Optical Communications: Explore Lasers in Space

When we return to the Moon, much will seem unchanged since humans first arrived in 1969. The flags placed by Apollo astronauts will be untouched by any breeze. The footprints left by man’s “small step” on its surface will still be visible across the Moon’s dusty landscape.

Our next generation of lunar explorers will require pioneering innovation alongside proven communications technologies. We’re developing groundbreaking technologies to help these astronauts fulfill their missions.

In space communications networks, lasers will supplement traditional radio communications, providing an advancement these explorers require. The technology, called optical communications, has been in development by our engineers over decades.

Optical communications, in infrared, has a higher frequency than radio, allowing more data to be encoded into each transmission. Optical communications systems also have reduced size, weight and power requirements. A smaller system leaves more room for science instruments; a weight reduction can mean a less expensive launch, and reduced power allows batteries to last longer.

On the path through this “Decade of Light,” where laser joins radio to enable mission success, we must test and demonstrate a number of optical communications innovations.

The Laser Communications Relay Demonstration (LCRD) mission will send data between ground stations in Hawaii and California through a spacecraft in an orbit stationary relative to Earth’s rotation. The demo will be an important first step in developing next-generation Earth-relay satellites that can support instruments generating too much data for today’s networks to handle.

The Integrated LCRD Low-Earth Orbit User Modem and Amplifier-Terminal will provide the International Space Station with a fully operational optical communications system. It will communicate data from the space station to the ground through LCRD. The mission applies technologies from previous optical communications missions for practical use in human spaceflight.

In deep space, we’re working to prove laser technologies with our Deep Space Optical Communications mission. A laser’s wavelength is smaller than radio, leaving less margin for error in pointing back at Earth from very, very far away. Additionally, as the time it takes for data to reach Earth increases, satellites need to point ahead to make sure the beam reaches the right spot at the right time. The Deep Space Optical Communications mission will ensure that our communications engineers can meet those challenges head-on.

An integral part of our journey back to the Moon will be our Orion spacecraft. It looks remarkably similar to the Apollo capsule, yet it hosts cutting-edge technologies. NASA’s Laser Enhanced Mission Communications Navigation and Operational Services (LEMNOS) will provide Orion with data rates as much as 100 times higher than current systems.

LEMNOS’s optical terminal, the Orion EM-2 Optical Communications System, will enable live, 4K ultra-high-definition video from the Moon. By comparison, early Apollo cameras filmed only 10 frames per second in grainy black-and-white. Optical communications will provide a “giant leap” in communications technology, joining radio for NASA’s return to the Moon and the journey beyond.

NASA’s Space Communications and Navigation program office provides strategic oversight to optical communications research. At NASA’s Goddard Space Flight Center in Greenbelt, Maryland, the Exploration and Space Communications projects division is guiding a number of optical communications technologies from infancy to fruition. If you’re ever near Goddard, stop by our visitor center to check out our new optical communications exhibit. For more information, visit nasa.gov/SCaN and esc.gsfc.nasa.gov.

5 Questions from a Year of Education on the International Space Station

This year, we’re celebrating a Year of Education on the Station as astronauts and former teachers Joe Acaba and Ricky Arnold have made the International Space Station their home. While aboard, they have been sharing their love of science, technology, engineering and math, along with their passion for teaching. With the Year of Education on the Station is coming to a close, here are some of the highlights from students speaking to the #TeacherOnBoard from across the country!

Why do you feel it’s important to complete Christa McAuliffe’s lessons?

“The loss of Challenger not only affected a generation of school teachers but also a generation of school children who are now adults.” Ricky’s personal mission was to bring the Challenger Mission full circle and give it a sense of closure by teaching Christa’s Lost Lessons. See some of Christa’s Lost Lessons here.

Have you ever poured water out to see what happens?

The concept of surface tension is very apparent on the space station. Fluids do not spill out, they stick to each other. Cool fact: you can drink your fluids from the palm of your hand if you wanted to! Take a look at this demonstration that talks a little more about tension. 

How does your equipment stay attached to the wall?

The use of bungee cords as well as hook and loop help keep things in place in a microgravity environment. These two items can be found on the space station and on the astronaut’s clothing! Their pants often have hook and loop so they can keep things nearby if they need to be using their hands for something else. 

Did being a teacher provide any advantage to being an astronaut?

Being an effective communicator and having the ability to be adaptable are great skills to have as a teacher and as an astronaut. Joe Acaba has found that these skills have assisted him in his professional development.  

Since you do not use your bones and muscles as often because of microgravity, do you have to exercise? What type can you do?

The exercises that astronauts do aboard the space station help them maintain their bone density and muscle mass. They have access to resistance training through ARED (Advanced Resistive Exercise Device) which is a weight machine and for cardio, there is a bicycle and treadmill available to keep up with their physical activity.

Discover NASA Technology in Your Life

Have you ever wondered how space exploration impacts you? “Spinoffs” are products and services developed from NASA technology or improved through NASA partnerships. These innovations—first created to help explore space and study Earth—are responsible for billions of dollars in both revenue and saved costs, tens of thousands of jobs created, and for changing the world around us.

Our NASA Home & City interactive web platform allows you to explore some of the spinoff technologies you can find in your everyday life, demonstrating the wider benefits of America’s investments in its space program.

Here are the seven most unexpected items you can find in your homes and cities which were “spun off” from technologies to enable the study and exploration of space.

1. Wireless Headsets

“That’s one small step for man, one giant leap for mankind.” On July 20, 1969, millions were glued to their television sets when NASA astronaut Neil Armstrong offered these famous words via live broadcast, upon becoming the first man to ever step foot on the Moon. This historic transmission was delivered from Armstrong’s headset to the headsets of Mission Control personnel at NASA, and then on to the world.

Improved by the technology that carried Neil Armstrong’s words, more compact and comfortable headsets were developed for airline pilots in the 1960s and '70s. Today those advancements continue to evolve in all forms of communications and telephone equipment. Mobile headsets provide greater efficiency and flexibility for everyone from professionals to video gamers.

2. Water Quality Monitoring

On the International Space Station very little goes to waste. This includes water, which is recovered from every possible source, cleaned and recycled.

Following our development of a simplified bacteria test for water quality on the space station, one engineer created a foundation to distribute test kits suitable for use in rural communities around the world. Water contamination is still a major problem in many places, and the test helps local communities and governments obtain and share water quality data using a smartphone app.

3. Skin Cream

We know that on Earth, gravity is a constant. For astronauts in orbit, however, it’s a different story—and according to a scientist at NASA's Johnson Space Center, studying what happens to bodies in microgravity “can lead to significant new discoveries in human biology for the benefit of humankind.”

As our researchers experimented with replicating microgravity conditions in the lab, they invented a bioreactor that could help simulate conditions that human cells experience in a space-like environment. This allowed them to perform tissue-growth experiments on the ground and in space, and eventually, to consider the question of how to protect human cells from the toxic effects of long-duration space missions.

Now, thanks to this NASA-patented bioreactor, one company uses agents from human cells that produce collagen to enrich its skin cream products. Lab tests have shown the rejuvenating cream to increase skin moisture content by 76 percent and reduce darkness and wrinkles by more than 50 percent.

4. Acoustic Guitars

From its start, NASA has innovated in all branches of aeronautics, which has led to numerous advances in helicopters, including ways to limit vibrations as they fly and advanced composites to build tougher, safer vehicles. 

An industrious helicopter manufacturer that built up its expertise with NASA contracts later used the same special vibration analysis equipment to enhance the sound of acoustic guitars. The company also built the body out of a fiberglass composite used for rotor blades. The resulting instruments are stronger and less expensive to produce than those of traditional rosewood and produce a rich, full sound.

5. Tiny [Mobile] Homes

While the International Space Station is the largest spacecraft ever flown—it's about the size of a football field—living and working space for astronauts is still at a premium. NASA created a studio called the Habitability Design Center to experiment with the interior design of spacecraft to maximize usable space and make scientific research as efficient and effective as possible.

An architect who helped NASA design the interior of the International Space Station launched a company specializing in compact trailers for camping and exploration. Suitable for a full hookup campsite or going completely off-grid, the company's flagship trailer can accommodate two adults and two children for sleeping and can be customized with a range of features including a shower, refrigerator, toilet, and more. And it all fits into a unit light enough to be towed by a four-cylinder car.

6. Blue Light Blocking Ski Goggles

Skiers and snowboarders face extremely bright sunlight, especially when it's reflected off the white snow. That can make it hard to see, and not just because of glare. The blue in sunlight makes it more difficult to discern colors at the edge of the visible light spectrum, like reds. A NASA-designed filter used in snow goggles helps block up to 95 percent of blue light, making it easier for people on the slopes to see the terrain clearly.

7. Implants for the Hearing Impaired

Hearing aids, which make sound louder, can only do so much for those who were born or have become deaf. Cochlear implants work in a completely different way, converting sound into digital signals that can be processed by the brain.  And the technology traces back in part to a NASA space shuttle engineer who used skills in electronics instrumentation and his own experiences with hearing loss to develop an early version of the life-changing device.

These are just a few examples of thousands of NASA Spinoff and dual-purpose technologies benefiting the world around us.

Five Technologies Taking Aeronautics into the Future

Martian helicopters? Electric planes? Quiet supersonic flight?

The flight technologies of tomorrow are today’s reality at NASA. We’re developing a number of innovations that promise to change the landscape (skyscape?) of aviation. Here are five incredible aeronautic technologies currently in development:

 1. The X-59 QueSST and Quiet Supersonic Technology

It might sound like an oxymoron, but ‘quiet boom’ technology is all the rage with our Aeronautics Mission Directorate. The X-59 QueSST is an experimental supersonic jet that hopes to reduce the sound of a supersonic boom to a gentle thump. We will gauge public reaction to this ‘sonic thump,’ evaluating its potential impact if brought into wider use. Ultimately, if the commercial sector incorporates this technology, the return of supersonic passenger flight may become a reality!

 2. The X-57 Electric Plane

Electric cars? Pfft. We’re working on an electric PLANE. Modified from an existing general aviation aircraft, the X-57 will be an all-electric X-plane, demonstrating a leap-forward in green aviation. The plane seeks to reach a goal of zero carbon emissions in flight, running on batteries fed by renewable energy sources!

3. Second-Generation Search and Rescue Beacons

Our Search and Rescue office develops technologies for distress beacons and the space systems that locate them. Their new constellation of medium-Earth orbit instruments can detect a distress call near-instantaneously, and their second-generation beacons, hitting shelves soon, are an order of magnitude more accurate than the previous generation!

(The Search and Rescue office also recently debuted a coloring book that doesn’t save lives but will keep your crayon game strong.)

4. Earth from the Air

Earth science? We got it.

We don’t just use satellite technology to monitor our changing planet. We have a number of missions that monitor Earth’s systems from land, sea and air. In the sky, we use flying laboratories to assess things like air pollution, greenhouse gasses, smoke from wildfires and so much more. Our planet may be changing, but we have you covered.

5. Icing Research

No. Not that icing.

Much better.

Though we at NASA are big fans of cake frosting, that’s not the icing we’re researching. Ice that forms on a plane mid-flight can disrupt the airflow around the plane and inside the engine, increasing drag, reducing lift and even causing loss of power. Ice can also harm a number of other things important to a safe flight. We’re developing tools and methods for evaluating and simulating the growth of ice on aircraft. This will help aid in designing future aircraft that are more resilient to icing, making aviation safer.

There you have it, five technologies taking aeronautics into the future, safely down to the ground and even to other planets! To stay up to date on the latest and greatest in science and technology, check out our website: www.nasa.gov.

Solar System: 10 Ways Interns Are Exploring Space With Us

Simulating alien worlds, designing spacecraft with origami and using tiny fossils to understand the lives of ancient organisms are all in a day’s work for interns at NASA.

Here’s how interns are taking our missions and science farther.

1. Connecting Satellites in Space

Becca Foust looks as if she’s literally in space – or, at least, on a sci-fi movie set. She’s surrounded by black, except for the brilliant white comet model suspended behind her. Beneath the socks she donned just for this purpose, the black floor reflects the scene like perfectly still water across a lake as she describes what happens here: “We have five spacecraft simulators that ‘fly’ in a specially designed flat-floor facility,” she says. “The spacecraft simulators use air bearings to lift the robots off the floor, kind of like a reverse air hockey table. The top part of the spacecraft simulators can move up and down and rotate all around in a similar way to real satellites.” It’s here, in this test bed on the Caltech campus, that Foust is testing an algorithm she’s developing to autonomously assemble and disassemble satellites in space. “I like to call it space K’nex, like the toys. We're using a bunch of component satellites and trying to figure out how to bring all of the pieces together and make them fit together in orbit,” she says. A NASA Space Technology Research Fellow, who splits her time between Caltech and NASA’s Jet Propulsion Laboratory (JPL), working with Soon-Jo Chung and Fred Hadaegh, respectively, Foust is currently earning her Ph.D. at the University of Illinois at Urbana-Champaign. She says of her fellowship, “I hope my research leads to smarter, more efficient satellite systems for in-space construction and assembly.”

2. Diving Deep on the Science of Alien Oceans

Three years ago, math and science were just subjects Kathy Vega taught her students as part of Teach for America. Vega, whose family emigrated from El Salvador, was the first in her family to go to college. She had always been interested in space and even dreamed about being an astronaut one day, but earned a degree in political science so she could get involved in issues affecting her community. But between teaching and encouraging her family to go into science, It was only a matter of time before she realized just how much she wanted to be in the STEM world herself. Now an intern at NASA JPL and in the middle of earning a second degree, this time in engineering physics, Vega is working on an experiment that will help scientists search for life beyond Earth. 

“My project is setting up an experiment to simulate possible ocean compositions that would exist on other worlds,” says Vega. Jupiter’s moon Europa and Saturn’s moon Enceladus, for example, are key targets in the search for life beyond Earth because they show evidence of global oceans and geologic activity. Those factors could allow life to thrive. JPL is already building a spacecraft designed to orbit Europa and planning for another to land on the icy moon’s surface. “Eventually, [this experiment] will help us prepare for the development of landers to go to Europa, Enceladus and another one of Saturn’s moons, Titan, to collect seismic measurements that we can compare to our simulated ones,” says Vega. “I feel as though I'm laying the foundation for these missions.”

3. Unfolding Views on Planets Beyond Our Solar System

“Origami is going to space now? This is amazing!” Chris Esquer-Rosas had been folding – and unfolding – origami since the fourth grade, carefully measuring the intricate patterns and angles produced by the folds and then creating new forms from what he’d learned. “Origami involves a lot of math. A lot of people don't realize that. But what actually goes into it is lots of geometric shapes and angles that you have to account for,” says Esquer-Rosas. Until three years ago, the computer engineering student at San Bernardino College had no idea that his origami hobby would turn into an internship opportunity at NASA JPL. That is, until his long-time friend, fellow origami artist and JPL intern Robert Salazar connected him with the Starshade project. Starshade has been proposed as a way to suppress starlight that would otherwise drown out the light from planets outside our solar system so we can characterize them and even find out if they’re likely to support life. Making that happen requires some heavy origami – unfurling a precisely-designed, sunflower-shaped structure the size of a baseball diamond from a package about half the size of a pitcher’s mound. It’s Esquer-Rosas’ project this summer to make sure Starshade’s “petals” unfurl without a hitch. Says Esquer-Rosas, “[The interns] are on the front lines of testing out the hardware and making sure everything works. I feel as though we're contributing a lot to how this thing is eventually going to deploy in space.”

4. Making Leaps in Extreme Robotics

Wheeled rovers may be the norm on Mars, but Sawyer Elliott thinks a different kind of rolling robot could be the Red Planet explorer of the future. This is Elliott’s second year as a fellow at NASA JPL, researching the use of a cube-shaped robot for maneuvering around extreme environments, like rocky slopes on Mars or places with very little gravity, like asteroids. A graduate student in aerospace engineering at Cornell University, Elliott spent his last stint at JPL developing and testing the feasibility of such a rover. “I started off working solely on the rover and looking at can we make this work in a real-world environment with actual gravity,” says Elliott. “It turns out we could.” So this summer, he’s been improving the controls that get it rolling or even hopping on command. In the future, Elliott hopes to keep his research rolling along as a fellow at JPL or another NASA center. “I'm only getting more and more interested as I go, so I guess that's a good sign,” he says.

5. Starting from the Ground Up

Before the countdown to launch or the assembling of parts or the gathering of mission scientists and engineers, there are people like Joshua Gaston who are helping turn what’s little more than an idea into something more. As an intern with NASA JPL’s project formulation team, Gaston is helping pave the way for a mission concept that aims to send dozens of tiny satellites, called CubeSats, beyond Earth’s gravity to other bodies in the solar system. “This is sort of like step one,” says Gaston. “We have this idea and we need to figure out how to make it happen.” Gaston’s role is to analyze whether various CubeSat models can be outfitted with the needed science instruments and still make weight. Mass is an important consideration in mission planning because it affects everything from the cost to the launch vehicle to the ability to launch at all. Gaston, an aerospace engineering student at Tuskegee University, says of his project, “It seems like a small role, but at the same time, it's kind of big. If you don't know where things are going to go on your spacecraft or you don't know how the spacecraft is going to look, it's hard to even get the proposal selected.”

6. Finding Life on the Rocks

By putting tiny samples of fossils barely visible to the human eye through a chemical process, a team of NASA JPL scientists is revealing details about organisms that left their mark on Earth billions of years ago. Now, they have set their sights on studying the first samples returned from Mars in the future. But searching for signatures of life in such a rare and limited resource means the team will have to get the most science they can out of the smallest sample possible. That’s where Amanda Allen, an intern working with the team in JPL’s Astrobiogeochemistry, or abcLab, comes in. “Using the current, state-of-the-art method, you need a sample that’s 10 times larger than we’re aiming for,” says Allen, an Earth science undergraduate at the University of California, San Diego, who is doing her fifth internship at JPL. “I’m trying to get a different method to work.” Allen, who was involved in theater and costume design before deciding to pursue Earth science, says her “superpower” has always been her ability to find things. “If there’s something cool to find on Mars related to astrobiology, I think I can help with that,” she says.

7. Taking Space Flight Farther

If everything goes as planned and a thruster like the one Camille V. Yoke is working on eventually helps send astronauts to Mars, she’ll probably be first in line to play the Mark Watney role. “I'm a fan of the Mark Watney style of life [in “The Martian”], where you're stranded on a planet somewhere and the only thing between you and death is your own ability to work through problems and engineer things on a shoestring,” says Yoke. A physics major at the University of South Carolina, Yoke is interning with a team that’s developing a next-generation electric thruster designed to accelerate spacecraft more efficiently through the solar system. “Today there was a brief period in which I knew something that nobody else on the planet knew – for 20 minutes before I went and told my boss,” says Yoke. “You feel like you're contributing when you know that you have discovered something new.”

8. Searching for Life Beyond Our Solar System

Without the option to travel thousands or even tens of light-years from Earth in a single lifetime, scientists hoping to discover signs of life on planets outside our solar system, called exoplanets, are instead creating their own right here on Earth. This is Tre’Shunda James’ second summer simulating alien worlds as an intern at NASA JPL. Using an algorithm developed by her mentor, Renyu Hu, James makes small changes to the atmospheric makeup of theoretical worlds and analyzes whether the combination creates a habitable environment. “This model is a theoretical basis that we can apply to many exoplanets that are discovered,” says James, a chemistry and physics major at Occidental College in Los Angeles. “In that way, it's really pushing the field forward in terms of finding out if life could exist on these planets.” James, who recently became a first-time co-author on a scientific paper about the team’s findings, says she feels as though she’s contributing to furthering the search for life beyond Earth while also bringing diversity to her field. “I feel like just being here, exploring this field, is pushing the boundaries, and I'm excited about that.”

9. Spinning Up a Mars Helicopter

Chloeleen Mena’s role on the Mars Helicopter project may be small, but so is the helicopter designed to make the first flight on the Red Planet. Mena, an electrical engineering student at Embry-Riddle Aeronautical University, started her NASA JPL internship just days after NASA announced that the helicopter, which had been in development at JPL for nearly five years, would be going to the Red Planet aboard the Mars 2020 rover. This summer, Mena is helping test a part needed to deploy the helicopter from the rover once it lands on Mars, as well as writing procedures for future tests. “Even though my tasks are relatively small, it's part of a bigger whole,” she says.

10. Preparing to See the Unseen on Jupiter's Moon Europa

In the 2020s, we’re planning to send a spacecraft to the next frontier in the search for life beyond Earth: Jupiter’s moon Europa. Swathed in ice that’s intersected by deep reddish gashes, Europa has unveiled intriguing clues about what might lie beneath its surface – including a global ocean that could be hospitable to life. Knowing for sure hinges on a radar instrument that will fly aboard the Europa Clipper orbiter to peer below the ice with a sort of X-ray vision and scout locations to set down a potential future lander. To make sure everything works as planned, NASA JPL intern Zachary Luppen is creating software to test key components of the radar instrument. “Whatever we need to do to make sure it operates perfectly during the mission,” says Luppen. In addition to helping things run smoothly, the astronomy and physics major says he hopes to play a role in answering one of humanity’s biggest questions. “Contributing to the mission is great in itself,” says Luppen. “But also just trying to make as many people aware as possible that this science is going on, that it's worth doing and worth finding out, especially if we were to eventually find life on Europa. That changes humanity forever!”

5 Examples of How Our Satellite Data is Helping the Planet

We could talk all day about how our satellite data is crucial for Earth science…tracking ocean currents, monitoring natural disasters, soil mapping – the list goes on and on.

But did you know there is another way this data can improve life here on Earth?

Our satellite data can be used to build businesses and commercial products – but finding and using this data has been a daunting task for many potential users because it’s been stored across dozens of websites.

Until now.

Our Technology Transfer program has just released their solution to make finding data easier, called The NASA Remote Sensing Toolkit (RST).

RST offers an all-in-one approach to finding and using our Earth Science data, the tools needed to analyze it, and software to build your own tools.  

Before, we had our petabytes on petabytes of information spread out across dozens of websites – not to mention the various software tools needed to interpret the data. 

Now, RST helps users find everything they need while having only one browser open.

Feeling inspired to innovate with our data? Here are just a few examples of how other companies have taken satellite data and turned it into products, known as NASA spinoffs, that are helping our planet today.

1. Bringing Landscape into Focus

We have a number of imaging systems for locating fires, but none were capable of identifying small fires or indicating the flames’ intensity. Thanks to a series of Small Business Innovation Research (SBIR) contracts between our Ames Research Center and Xiomas Technologies LLC, the Wide Area Imager aerial scanner does just that. While we and the U.S. Forest Service use it for fire detection, the tool is also being used by municipalities for detailed aerial surveillance projects.

2. Monitoring the Nation’s Forests with the Help of Our Satellites

Have you ever thought about the long-term effects of natural disasters, such as hurricanes, on forest life? How about the big-time damage caused by little pests, like webworms? 

Our Stennis Space Center did, along with multiple forest services and environmental threat assessment centers. They partnered to create an early warning system to identify, characterize, and track disturbances from potential forest threats using our satellite data. The result was ForWarn, which is now being used by federal and state forest and natural resource managers.

3. Informing Forecasts of Crop Growth

Want to hear a corny story?

Every year Stennis teams up with the U.S. Department of Agriculture to host a program called Ag 20/20 to utilize remote sensing technology for operational use in agricultural crop management practices at the level of individual farms. During Ag 20/20 in 2000, an engineering contractor developed models for using our satellite data to predict corn crop yield. The model was eventually sold to Genscape Inc., which has commercialized it as LandViewer. Sold under a subscription model, LandViewer software provides predictions of corn production to ethanol plants and grain traders.

4. Water Mapping Technology Rebuilds Lives in Arid Regions

No joking around here. Lives depend on the ability to find precious water in areas with little of it.  

Using our Landsat satellite and other topographical data, Radar Technologies International developed an algorithm-based software program that can locate underground water sources. Working with international organizations and governments, the firm is helping to provide water for refugees and other people in drought-stricken regions such as Kenya, Sudan, and Afghanistan.

5. Satellite Maps Deliver More Realistic Gaming

Are you more of the creative type? This last entry used satellite data to help people really get into their gameplay.

When Electronic Arts (EA) decided to make SSX, a snowboarding video game, it faced challenges in creating realistic-looking mountains. The solution was our ASTER Global Digital Elevation Map, made available by our Jet Propulsion Laboratory, which EA used to create 28 real-life mountains from 9 different ranges for its award-winning game.

Chemical Space Gardens

You know that colorful crystal garden you grew as a kid?

Yeah, we do that in space now. 

Chemical Gardens, a new investigation aboard the International Space Station takes a classic science experiment to space with the hope of improving our understanding of gravity’s impact on their structural formation.

Here on Earth, chemical gardens are most often used to teach students about things like chemical reactions.

Chemical gardens form when dissolvable metal salts are placed in an aqueous solution containing anions such as silicate, borate, phosphate, or carbonate.

Delivered to the space station aboard SpaceX’S CRS-15 cargo mission, the samples for this experiment will be processed by crew members and grown throughout Expedition 56 before returning to Earth.

Results from this investigation could provide a better understanding of cement science and improvements to biomaterial devices used for scaffolding, for use both in space and on Earth.

6 Fun Facts About Our New Hexapod Robot

Satellites are crucial to everyday life and cost hundreds of millions of dollars to manufacture and launch. Currently, they are simply decommissioned when they run out of fuel. There is a better way, and it centers on satellite servicing, which can make spaceflight more sustainable, affordable, and resilient. Our satellite servicing technologies will open up a new world where fleet managers can call on robotic mechanics to diagnose, maintain and extend the lifespan of their assets.

Our new and unique robot is designed to test robotic satellite servicing capabilities. Standing 10 feet tall and 16 feet wide, the six-legged “hexapod” robot helps engineers perfect technologies before they’re put to use in space.

Here are SIX interesting facts about the hexapod:

1. The hexapod has six degrees of freedom. 

This essentially means the robot can move in six directions—three translational directions (forward and backward, up and down and left and right), and three rotational directions (roll, pitch and yaw). Because of its wide range of movement, the hexapod mimics the way a satellite moves in zero gravity.

2. It can move up to eight inches per second and can extend up to 13 feet (but usually doesn’t).

Like most space simulators, the hexapod typically moves slowly at about one inch per second. During tests, it remains positioned about nine feet off the floor to line up with and interact with a robotic servicing arm mounted to an arch nearby. However, the robot can move at speeds up to eight inches per second and extend/reach nearly 13 feet high!

3. The hexapod tests mission elements without humans.

The hexapod is crucial to testing for our Restore-L project, which will prove a combination of technologies needed to robotically refuel a satellite not originally designed to be refueled in space.

Perhaps the most difficult part of refueling a satellite in space is the autonomous rendezvous and grapple stage. A satellite in need of fuel might be moving 16,500 miles per hour in the darkness of space. A servicer satellite will need to match its speed and approach the client satellite, then grab it. This nail-biting stage needs to be done autonomously by the spacecraft’s systems (no humans controlling operations from the ground).

The hexapod helps us practice this never-before-attempted feat in space-like conditions. Eventually a suite of satellite servicing capabilities could be incorporated in other missions.

4. This type of robot is also used for flight and roller coaster simulators.

Because of the hexapod’s unparalleled* ability to handle a high load capacity and range of movement, while maintaining a high degree of precision and repeatability, a similar kind of robot is used for flight and roller coaster simulators.

*Pun intended: the hexapod is what is referred to as a parallel motion robot

5. The hexapod was designed and made in the U S of A.

The hexapod was designed and built by a small, New Hampshire-based company called Mikrolar. Mikrolar designs and produces custom robots that offer a wide range of motion and high degree of precision, for a wide variety of applications.

6. The robot lives at our Goddard Space Flight Center’s Robotic Operations Center.

The hexapod conducts crucial tests at our Goddard Space Flight Center’s Robotic Operations Center (ROC). The ROC is a 5,000-square-foot facility with 50 feet high ceilings. It acts as an incubator for satellite servicing technologies. Within its black curtain-lined walls, space systems, components and tasks are put to the test in simulated environments, refined and finally declared ready for action in orbit.

The hexapod is not alone in the ROC. Five other robots test satellite servicing capabilities. Engineers use these robots to practice robotic repairs on satellites rendezvousing with objects in space.

Navigating Space by the Stars

A sextant is a tool for measuring the angular altitude of a star above the horizon and has helped guide sailors across oceans for centuries. It is now being tested aboard the International Space Station as a potential emergency navigation tool for guiding future spacecraft across the cosmos. The Sextant Navigation investigation will test the use of a hand-held sextant that utilizes star sighting in microgravity.

5 Out-of-This World Technologies Developed for Our Webb Space Telescope

Our James Webb Space Telescope is the most ambitious and complex space science observatory ever built. It will study every phase in the history of our universe, ranging from the first luminous glows after the Big Bang, to the formation of solar systems capable of supporting life on planets like Earth, to the evolution of our own Solar System.

In order to carry out such a daring mission, many innovative and powerful new technologies were developed specifically to enable Webb to achieve its primary mission.  

Here are 5 technologies that were developed to help Webb push the boundaries of space exploration and discovery:

1. Microshutters

Microshutters are basically tiny windows with shutters that each measure 100 by 200 microns, or about the size of a bundle of only a few human hairs. 

The microshutter device will record the spectra of light from distant objects (spectroscopy is simply the science of measuring the intensity of light at different wavelengths. The graphical representations of these measurements are called spectra.)

Other spectroscopic instruments have flown in space before but none have had the capability to enable high-resolution observation of up to 100 objects simultaneously, which means much more scientific investigating can get done in less time. 

Read more about how the microshutters work HERE.

2. The Backplane

Webb's backplane is the large structure that holds and supports the big hexagonal mirrors of the telescope, you can think of it as the telescope’s “spine”. The backplane has an important job as it must carry not only the 6.5 m (over 21 foot) diameter primary mirror plus other telescope optics, but also the entire module of scientific instruments. It also needs to be essentially motionless while the mirrors move to see far into deep space. All told, the backplane carries more than 2400kg (2.5 tons) of hardware.

This structure is also designed to provide unprecedented thermal stability performance at temperatures colder than -400°F (-240°C). At these temperatures, the backplane was engineered to be steady down to 32 nanometers, which is 1/10,000 the diameter of a human hair!

Read more about the backplane HERE.

3. The Mirrors

One of the Webb Space Telescope's science goals is to look back through time to when galaxies were first forming. Webb will do this by observing galaxies that are very distant, at over 13 billion light years away from us. To see such far-off and faint objects, Webb needs a large mirror. 

Webb's scientists and engineers determined that a primary mirror 6.5 meters across is what was needed to measure the light from these distant galaxies. Building a mirror this large is challenging, even for use on the ground. Plus, a mirror this large has never been launched into space before! 

If the Hubble Space Telescope's 2.4-meter mirror were scaled to be large enough for Webb, it would be too heavy to launch into orbit. The Webb team had to find new ways to build the mirror so that it would be light enough - only 1/10 of the mass of Hubble's mirror per unit area - yet very strong. 

Read more about how we designed and created Webb’s unique mirrors HERE.

4. Wavefront Sensing and Control

Wavefront sensing and control is a technical term used to describe the subsystem that was required to sense and correct any errors in the telescope’s optics. This is especially necessary because all 18 segments have to work together as a single giant mirror.

The work performed on the telescope optics resulted in a NASA tech spinoff for diagnosing eye conditions and accurate mapping of the eye.  This spinoff supports research in cataracts, keratoconus (an eye condition that causes reduced vision), and eye movement – and improvements in the LASIK procedure.

Read more about the tech spinoff HERE. 

5. Sunshield and Sunshield Coating

Webb’s primary science comes from infrared light, which is essentially heat energy. To detect the extremely faint heat signals of astronomical objects that are incredibly far away, the telescope itself has to be very cold and stable. This means we not only have to protect Webb from external sources of light and heat (like the Sun and the Earth), but we also have to make all the telescope elements very cold so they don't emit their own heat energy that could swamp the sensitive instruments. The temperature also must be kept constant so that materials aren't shrinking and expanding, which would throw off the precise alignment of the optics.

Each of the five layers of the sunshield is incredibly thin. Despite the thin layers, they will keep the cold side of the telescope at around -400°F (-240°C), while the Sun-facing side will be 185°F (85°C). This means you could actually freeze nitrogen on the cold side (not just liquify it), and almost boil water on the hot side. The sunshield gives the telescope the equivalent protection of a sunscreen with SPF 1 million!

Science Launching to Station Looks Forward and Back

Some of the earliest human explorers used mechanical tools called sextants to navigate vast oceans and discover new lands. Today, high-tech tools navigate microscopic DNA to discover previously unidentified organisms. Scientists aboard the International Space Station soon will have both types of tools at their disposal.

Orbital ATK’s Cygnus spacecraft is scheduled to launch its ninth contracted cargo resupply mission to the space station no earlier than May 21. Sending crucial science, supplies and cargo to the crew of six humans living and working on the orbiting laboratory.

Our Gemini missions conducted the first sextant sightings from a spacecraft, and designers built a sextant into Apollo vehicles as a lost-communications navigation backup. The Sextant Navigation investigation tests use of a hand-held sextant for emergency navigation on missions in deep space as humans begin to travel farther from Earth.

Jim Lovell (far left) demonstrated on Apollo 8 that sextant navigation could return a space vehicle home. 

The remoteness and constrained resources of living in space require simple but effective processes and procedures to monitor the presence of microbial life, some of which might be harmful. Biomolecule Extraction and Sequencing Technology (BEST) advances the use of sequencing processes to identify microbes aboard the space station that current methods cannot detect and to assess mutations in the microbial genome that may be due to spaceflight.  

Genes in Space 3 performed in-flight identification of bacteria on the station for the first time. BEST takes that one step farther, identifying unknown microbial organisms using a process that sequences directly from a sample with minimal preparation, rather than with the traditional technique that requires growing a culture from the sample.

Adding these new processes to the proven technology opens new avenues for inflight research, such as how microorganisms on the station change or adapt to spaceflight.

The investigation’s sequencing components provide important information on the station’s microbial occupants, including which organisms are present and how they respond to the spaceflight environment -- insight that could help protect humans during future space exploration. Knowledge gained from BEST could also provide new ways to monitor the presence of microbes in remote locations on Earth.

Moving on to science at a scale even smaller than a microbe, the new Cold Atom Lab (CAL) facility could help answer some big questions in modern physics.

CAL creates a temperature ten billion (Yup. BILLION) times colder than the vacuum of space, then uses lasers and magnetic forces to slow down atoms until they are almost motionless. CAL makes it possible to observe these ultra-cold atoms for much longer in the microgravity environment on the space station than would be possible on the ground.

Results of this research could potentially lead to a number of improved technologies, including sensors, quantum computers and atomic clocks used in spacecraft navigation.

A partnership between the European Space Agency (ESA) and Space Application Services (SpaceAps), The International Commercial Experiment, or ICE Cubes Service, uses a sliding framework permanently installed on the space station and “plug-and-play” Experiment Cubes.

The Experiment Cubes are easy to install and remove, come in different sizes and can be built with commercial off-the-shelf components, significantly reducing the cost and time to develop experiments.

ICE Cubes removes barriers that limit access to space, providing more people access to flight opportunities. Potential fields of research range from pharmaceutical development to experiments on stem cells, radiation, and microbiology, fluid sciences, and more.

Meet Our Latest CubeSats

When the next Orbital ATK cargo mission to the International Space Station blasts off from Wallops Flight Facility in Virginia on May 20 at 5:04 a.m. EDT carrying science and supplies, the Cygnus spacecraft will also be carrying a few of our latest CubeSats.

The International Space Station is often used to deploy small satellites, a low-cost way to test technology and science techniques in space.

On board this time, for deployment later this summer, are...

The ‘Rabbit’ in the RainCube

As its name suggests, RainCube will use radar to measure rain and snowfall. CubeSats are measured in increments of 1U (A CubeSat unit, or 1U, is roughly equivalent to a 4-inch box, or 10x10x10 centimeters). The RainCube antenna has to be small enough to be crammed into a 1.5U container; the entire satellite is about as big as a cereal box.

"It's like pulling a rabbit out of a hat," said Nacer Chahat, a specialist in antenna design at our Jet Propulsion Laboratory. "Shrinking the size of the radar is a challenge for us. As space engineers, we usually have lots of volume, so building antennas packed into a small volume isn't something we're trained to do."

That small antenna will deploy in space, like an upside-down umbrella. To maintain its small size, the antenna relies on the high-frequency Ka-band wavelength – good for profiling rain and snow. Ka-band also allows for an exponential increase in sending data over long distances, making it the perfect tool for telecommunications.

Peering Into Clouds

TEMPEST-D will also study weather. Temporal Experiment for Storms and Tropical Systems – Demonstration (TEMPEST-D) has satellite technology with the potential to measure cloud and precipitation processes on a global basis. These measurements help improve understanding of Earth’s water cycle and weather predictions, particularly conditions inside storms.

TEMPEST-D millimeter-wave observations have the ability to penetrate into clouds to where precipitation initiation occurs. By measuring the evolution of clouds from the moment of the onset of precipitation, a future TEMPEST constellation mission could improve weather forecasting and improve our understanding of cloud processes, essential to understanding climate change.

Cutting Through the Noise

CubeRRT, also the size of a cereal box, will space test a small component designed to detect and filter radio frequency interference (RFI). RFI is everywhere, from cellphones, radio and TV transmissions, satellite broadcasts and other sources. You probably recognize it as that annoying static when you can’t seem to get your favorite radio station to come in clearly because another station is nearby on the dial.

The same interference that causes radio static also affects the quality of data that instruments like microwave radiometers collect. As the number of RFI-causing devices increases globally, our satellite instruments – specifically, microwave radiometers that gather data on soil moisture, meteorology, climate and more – will be more challenged in collecting high-quality data.

That’s where CubeSat Radiometer Radio frequency interference Technology (CubeRRT) comes in. The small satellite will be carrying a new technology to detect and filter any RFI the satellite encounters in real-time from space. This will reduce the amount of data that needs to be transmitted back to Earth – increasing the quality of important weather and climate measurements.

Searching the Halo of the Milky Way

Did you know that we’re still looking for half of the normal matter that makes up the universe? Scientists have taken a census of all the stars, galaxies and clusters of galaxies — and we’re coming up short, based on what we know about the early days of the cosmos.

That missing matter might be hiding in tendrils of hot gas between galaxies. Or it might be in the halos of hot gas around individual galaxies like our own Milky Way. But if it’s there, why haven’t we seen it? It could be that it’s so hot that it glows in a spectrum of X-rays we haven’t looked at before.

Image Credit: Blue Canyon Technologies

Enter HaloSat. Led by the University of Iowa, HaloSat will search the halo of the Milky Way for the emissions oxygen gives off at these very high temperatures. Most other X-ray satellites look at narrow patches of the sky and at individual sources. HaloSat will look at large swaths of the sky at a time, which will help us figure out the geometry of the halo — whether it surrounds the galaxy more like a fried egg or a sphere. Knowing the halo’s shape will in turn help us figure out the mass, which may help us discover if the universe’s missing matter is in galactic halos.

CubeSats for All

Small satellites benefit Earth and its people (us!) in multiple ways. From Earth imaging satellites that help meteorologists to predict storm strengths and direction, to satellites that focus on technology demonstrations to help determine what materials function best in a microgravity environment, the science enabled by CubeSats is diverse. 

They are also a pathway to space science for students. Our CubeSat Launch initiative (CSLI) provides access to space for small satellites developed by our Centers and programs, educational institutions and nonprofit organizations. Since the program began, more than 50 educational CubeSats have flown. In 2016, students built the first CubeSat deployed into space by an elementary school.

Why We Celebrate Search and Rescue Technologies on 4/06

Today (4/06), we celebrate the special radio frequency transmitted by emergency beacons to the international search and rescue network. 

This 406 MHz frequency, used only for search and rescue, can be "heard" by satellites hundreds of miles above the ground! The satellites then "forward" the location of the beacon back to Earth, helping first responders locate people in distress worldwide, whether from a plane crash, a boating accident or other emergencies.

Our Search and Rescue office, based out of our Goddard Space Flight Center, researches and develops emergency beacon technology, passing the technology to companies who manufacture the beacons, making them available to the public at retail stores. The beacons are designed for personal, maritime and aviation use.

The search and rescue network, Cospas-Sarsat, is an international program that ensures the compatibility of distress alert services with the needs of users. Its current space segment relies on instruments onboard low-Earth and geosynchronous orbiting satellites, hundreds to thousands of miles above us. 

Space instruments forward distress signals to the search and rescue ground segment, which is operated by partner organizations around the world! They manage specific regions of the ground network. For example, the National Oceanic and Atmospheric Administration (NOAA) operates the region containing the United States, which reaches across the Atlantic and Pacific Oceans as well as parts of Central and South America.

NOAA notifies organizations that coordinate search and rescue efforts of a 406 MHz distress beacon's activation and location. Within the U.S., the U.S. Air Force responds to land-based emergencies and the U.S. Coast Guard responds to water-based emergencies. Local public service organizations like police and fire departments, as well as civilian volunteers, serve as first responders.

Here at NASA, we research, design and test search and rescue instruments and beacons to refine the existing network. Aeronautical beacon tests took place at our Langley Research Center in 2015. Using a 240-foot-high structure originally used to test Apollo spacecraft, our Search and Rescue team crashed three planes to test the survivability of these beacons, developing guidelines for manufacturers and installation into aircraft.

In the future, first responders will rely on a new constellation of search and rescue instruments on GPS systems on satellites in medium-Earth orbit, not hundreds, but THOUSANDS of miles overhead. These new instruments will enable the search and rescue network to locate a distress signal more quickly than the current system and achieve accuracy an order of magnitude better, from a half mile to approximately 300 feet. Our Search and Rescue office is developing second-generation 406 MHz beacons that make full use of this new system.

We will also incorporate these second-generation beacons into the Orion Crew Survival System. The Advanced Next-Generation Emergency Locator (ANGEL) beacons will be attached to astronaut life preservers. After splashdown, if the Orion crew exits the capsule due to an emergency, these beacons will make sure we know the exact location of floating astronauts! Our Johnson Space Center is testing this technology for used in future human spaceflight and exploration missions.

If you're the owner of an emergency beacon, remember that beacon registration is free, easy and required by law.

Science-Heavy SpaceX Dragon Headed to Space Station

Heads up: a new batch of science is headed to the International Space Station aboard the SpaceX Dragon on April 2, 2018. Launching from Florida's Cape Canaveral Air Force Station atop a Falcon 9 rocket, this fire breathing (well, kinda…) spacecraft will deliver science that studies thunderstorms on Earth, space gardening, potential pathogens in space, new ways to patch up wounds and more.

Let's break down some of that super cool science heading 250 miles above Earth to the orbiting laboratory:

Sprites and Elves in Space

Atmosphere-Space Interactions Monitor (ASIM) experiment will survey severe thunderstorms in Earth's atmosphere and upper-atmospheric lightning, or transient luminous events. 

These include sprites, flashes caused by electrical break-down in the mesosphere; the blue jet, a discharge from cloud tops upward into the stratosphere; and ELVES, concentric rings of emissions caused by an electromagnetic pulse in the ionosphere.

Here's a graphic showing the layers of the atmosphere for reference:

Metal Powder Fabrication

Our Sample Cartridge Assembly (MSL SCA-GEDS-German) experiment will determine underlying scientific principles for a fabrication process known as liquid phase sintering, in microgravity and Earth-gravity conditions.

Science term of the day: Liquid phase sintering works like building a sandcastle with just-wet-enough sand; heating a powder forms interparticle bonds and formation of a liquid phase accelerates this solidification, creating a rigid structure. But in microgravity, settling of powder grains does not occur and larger pores form, creating more porous and distorted samples than Earth-based sintering. 

Sintering has many applications on Earth, including metal cutting tools, automotive engine connecting rods, and self-lubricating bearings. It has potential as a way to perform in-space fabrication and repair, such as building structures on the moon or creating replacement parts during extraterrestrial exploration.

Plants in space! It's l[a]unch time!

Understanding how plants respond to microgravity and demonstrating reliable vegetable production in space represent important steps toward the goal of growing food for future long-duration missions. The Veggie Passive Orbital Nutrient Delivery System (Veggie PONDS) experiment will test a passive nutrient delivery system in the station's Veggie plant growth facility by cultivating lettuce and mizuna greens for harvest and consumption on orbit.

The PONDS design features low mass and low maintenance, requires no additional energy, and interfaces with the Veggie hardware, accommodating a variety of plant types and growth media.

Quick Science Tip: Download the Plant Growth App to grow your own veggies in space! Apple users can download the app HERE! Android users click HERE!

Testing Materials in Space

The Materials ISS Experiment Flight Facility (MISSE-FF) experiment will provide a unique platform for testing how materials, coatings and components react in the harsh environment of space.

A continuation of a previous experiment, this version's new design eliminates the need for astronauts to perform spacewalks for these investigations. New technology includes power and data collection options and the ability to take pictures of each sample on a monthly basis, or more often if required. The testing benefits a variety of industries, including automotive, aeronautics, energy, space, and transportation.

New Ways to Develop Drugs in Space

Microgravity affects movement and effectiveness of drugs in unique ways. Microgravity studies already have resulted in innovative medicines to treat cancer, for example. The Metabolic Tracking investigation determines the possibility of developing improved drugs in microgravity, using a new method to test the metabolic impacts of drug compounds. This could lead to more effective, less expensive drugs.

SpaceX Dragon breathes Astronomical Amounts of Science to Space Station

SpaceX is helping the crew members aboard the International Space Station get down and nerdy as they launch their Dragon cargo spacecraft into orbit for the 13th commercial resupply mission, targeted for Dec. 15 from our Kennedy Space Center in Florida. 

This super science-heavy flight will deliver experiments and equipment that will study phenomena on the Sun, materials in microgravity, space junk and more. 

Here are some highlights of research that will be delivered to the station:

ZBLAN Fiber Optics Tested in Space!

The Optical Fiber Production in Microgravity (Made in Space Fiber Optics) experiment demonstrates the benefits of manufacturing fiber optic filaments in a microgravity environment. This investigation will attempt to pull fiber optic wire from ZBLAN, a heavy metal fluoride glass commonly used to make fiber optic glass.

When ZBLAN is solidified on Earth, its atomic structure tends to form into crystals. Research indicates that ZBLAN fiber pulled in microgravity may not crystalize as much, giving it better optical qualities than the silica used in most fiber optic wire. 

Total and Spectral Solar Irradiance Sensor is Totally Teaching us About Earth’s Climate

The Total and Spectral Solar Irradiance Sensor, or TSIS, monitors both total solar irradiance and solar spectral irradiance, measurements that represent one of the longest space-observed climate records. Solar irradiance is the output of light energy from the entire disk of the Sun, measured at the Earth. This means looking at the Sun in ways very similar to how we observe stars rather than as an image with details that our eye can resolve.

Understanding the variability and magnitude of solar irradiance is essential to understanding Earth’s climate.  

Sensor Monitors Space Station Environment for Space Junk

The Space Debris Sensor (SDS) will directly measure the orbital debris environment around the space station for two to three years.

Above, see documentation of a Micro Meteor Orbital Debris strike on one of the window’s within the space station’s Cupola. 

Research from this investigation could help lower the risk to human life and critical hardware by orbital debris.

Self-Assembling and Self-Replicating Materials in Space!

Future space exploration may utilize self-assembly and self-replication to make materials and devices that can repair themselves on long duration missions. 

The Advanced Colloids Experiment- Temperature-7 (ACE-T-7) investigation involves the design and assembly of 3D structures from small particles suspended in a fluid medium. 

Melting Plastics in Microgravity

The Transparent Alloys project seeks to improve the understanding of the melting and solidification processes in plastics in microgravity. Five investigations will be conducted as a part of the Transparent Alloys project.

These European Space Agency (ESA) investigations will allow researchers to study this phenomena in the microgravity environment, where natural convection will not impact the results.  

Studying Slime (or…Algae, at Least) on the Space Station

Arthrospira B, an ESA investigation, will examine the form, structure and physiology of the Arthrospira sp. algae in order to determine the reliability of the organism for future spacecraft biological life support systems.

The development of these kinds of regenerative life support systems for spaceflight could also be applied to remote locations on Earth where sustainability of materials is important.

Reinventing the Wheel

Planning a trip to the Moon? Mars? You’re going to need good tires…

Exploration requires mobility. And whether you’re on Earth or as far away as the Moon or Mars, you need good tires to get your vehicle from one place to another. Our decades-long work developing tires for space exploration has led to new game-changing designs and materials. Yes, we’re reinventing the wheel—here’s why.

Wheels on the Moon

Early tire designs were focused on moving hardware and astronauts across the lunar surface. The last NASA vehicle to visit the Moon was the Lunar Roving Vehicle during our Apollo missions. The vehicle used four large flexible wire mesh wheels with stiff inner frames. We used these Apollo era tires as the inspiration for new designs using newer materials and technology to better function on a lunar surface.

Up springs a new idea

During the mid-2000s, we worked with industry partner Goodyear to develop the Spring Tire, an airless compliant tire that consists of several hundred coiled steel wires woven into a flexible mesh, giving the tires the ability to support high loads while also conforming to the terrain. The Spring Tire has been proven to generate very good traction and durability in soft sand and on rocks.

Spring Tires for Mars

A little over a year after the Mars Curiosity Rover landed on Mars, engineers began to notice significant wheel damage in 2013 due to the unexpectedly harsh terrain. That’s when engineers began developing new Spring Tire prototypes to determine if they would be a new and better solution for exploration rovers on Mars.

In order for Spring Tires to go the distance on Martian terrain, new materials were required. Enter nickel titanium, a shape memory alloy with amazing capabilities that allow the tire to deform down to the axle and return to its original shape.

These tires can take a lickin’

After building the shape memory alloy tire, Glenn engineers sent it to the Jet Propulsion Laboratory’s Mars Life Test Facility. It performed impressively on the punishing track.

Why reinvent the wheel? It’s worth it.

New, high performing tires would allow lunar and Mars rovers to explore greater regions of the surface than currently possible. They conform to the terrain and do not sink as much as rigid wheels, allowing them to carry heavier payloads for the same given mass and volume. Also, because they absorb energy from impacts at moderate to high speeds, there is potential for use on crewed exploration vehicles which are expected to move at speeds significantly higher than the current Mars rovers.

Airless tires on Earth

Maybe. Recently, engineers and materials scientists have been testing a spinoff tire version that would work on cars and trucks on Earth. Stay tuned as we continue to push the boundaries on traditional concepts for exploring our world and beyond.

13 Reasons to Have an Out-of-This-World Friday (the 13th)

1. Not all of humanity is bound to the ground

Since 2000, the International Space Station has been continuously occupied by humans. There, crew members live and work while conducting important research that benefits life on Earth and will even help us eventually travel to deep space destinations, like Mars.

2. We’re working to develop quieter supersonic aircraft that would allow you to travel from New York to Los Angeles in 2 hours

We are working hard to make flight greener, safer and quieter – all while developing aircraft that travel faster, and building an aviation system that operates more efficiently. Seventy years after Chuck Yeager broke the sound barrier in the Bell X-1 aircraft, we’re continuing that supersonic X-plane legacy by working to create a quieter supersonic jet with an aim toward passenger flight.

3. The spacecraft, rockets and systems developed to send astronauts to low-Earth orbit as part of our Commercial Crew Program is also helping us get to Mars

Changes to the human body during long-duration spaceflight are significant challenges to solve ahead of a mission to Mars and back. The space station allows us to perform long duration missions without leaving Earth’s orbit.

Although they are orbiting Earth, space station astronauts spend months at a time in near-zero gravity, which allows scientists to study several physiological changes and test potential solutions. The more time they spend in space, the more helpful the station crew members can be to those on Earth assembling the plans to go to Mars.

4. We’re launching a spacecraft in 2018 that will go “touch the Sun”

In the summer of 2018, we’re launching Parker Solar Probe, a spacecraft that will get closer to the Sun than any other in human history. Parker Solar Probe will fly directly through the Sun’s atmosphere, called the corona. Getting better measurements of this region is key to understanding our Sun. 

For instance, the Sun releases a constant outflow of solar material, called the solar wind. We think the corona is where this solar wind is accelerated out into the solar system, and Parker Solar Probe’s measurements should help us pinpoint how that happens.  

5. You can digitally fly along with spacecraft…that are actually in space…in real-time!

NASA’s Eyes are immersive, 3D simulations of real events, spacecraft locations and trajectories. Through this interactive app, you can experience Earth and our solar system, the universe and the spacecraft exploring them. Want to watch as our Juno spacecraft makes its next orbit around Juno? You can! Or relive all of the Voyager mission highlights in real-time? You can do that too! Download the free app HERE to start exploring.

6. When you feel far away from home, you can think of the New Horizons spacecraft as it heads toward the Kuiper Belt, and the Voyager spacecraft are beyond the influence of our sun…billions of miles away

Our New Horizons spacecraft completed its Pluto flyby in July 2015 and has continued on its way toward the Kuiper Belt. The spacecraft continues to send back important data as it travels toward deeper space at more than 32,000 miles per hour, and is ~3.2 billion miles from Earth.

In addition to New Horizons, our twin Voyager 1 and 2 spacecraft are exploring where nothing from Earth has flown before. Continuing on their more-than-37-year journey since their 1977 launches, they are each much farther away from Earth and the sun than Pluto. In August 2012, Voyager 1 made the historic entry into interstellar space, the region between the stars, filled with material ejected by the death of nearby stars millions of years ago.

7. There are humans brave enough to not only travel in space, but venture outside space station to perform important repairs and updates during spacewalks

Just this month (October 2017) we’ve already had two spacewalks on the International Space Station...with another scheduled on Oct. 20. 

Spacewalks are important events where crew members repair, maintain and upgrade parts of the International Space Station. These activities can also be referred to as EVAs – Extravehicular Activities. Not only do spacewalks require an enormous amount of work to prepare for, but they are physically demanding on the astronauts. They are working in the vacuum of space in only their spacewalking suit. 

8. Smart people are up all night working in control rooms all over NASA to ensure that data keeps flowing from our satellites and spacecraft

Our satellites and spacecraft help scientists study Earth and space. Missions looking toward Earth provide information about clouds, oceans, land and ice. They also measure gases in the atmosphere, such as ozone and carbon dioxide and the amount of energy that Earth absorbs and emits. And satellites monitor wildfires, volcanoes and their smoke.

9. A lot of NASA-developed tech has been transferred for use to the public

Our Technology Transfer Program highlights technologies that were originally designed for our mission needs, but have since been introduced to the public market. HERE are a few spinoff technologies that you might not know about.

10. We have a spacecraft currently traveling  to an asteroid to collect a sample and bring it back to Earth

OSIRIS-REx is our first-ever mission that will travel to an asteroid and bring a sample of it back to Earth. Currently, the spacecraft is on its way to asteroid Bennu where it will survey and map the object before it “high-fives” the asteroid with its robotic arm to collect a sample, which it will send to Earth.

If everything goes according to plan, on Sept. 24, 2023, the capsule containing the asteroid sample will make a soft landing in the Utah desert.

11. There are Earth-sized planets outside our solar system that may be habitable

To date, we have confirmed 3,000+ exoplanets, which are planets outside our solar system that orbit a Sun-like star. Of these 3,000, some are in the habitable zone – where the temperature is just right for liquid water to exist on the surface.  

Recently, our Spitzer Space Telescope revealed the first known system of SEVEN Earth-size planets around a single star. Three of these plants are firmly in the habitable zone, and could have liquid water on the surface, which is key to life as we know it.

12. Earth looks like art from space

In 1960, the United States put its first Earth-observing environmental satellite into orbit around the planet. Over the decades, these satellites have provided invaluable information, and the vantage point of space has provided new perspectives on Earth.

The beauty of Earth is clear, and the artistry ranges from the surreal to the sublime.

13. We’re building a telescope that will be able to see the first stars ever formed in the universe

Wouldn’t it be neat to see a period of the universe’s history that we’ve never seen before? That’s exactly what the James Webb Space Telescope (JWST) will be able to do…plus more!

Specifically, Webb will see the first objects that formed as the universe cooled down after the Big Bang. We don’t know exactly when the universe made the first stars and galaxies – or how for that matter. That is what we are building Webb to help answer.

Happy Friday the 13th! We hope it’s out-of-this-world!

Happy National Techies Day!

October 3 is National Techies Day…and here at NASA we have quite a few people who get REALLY excited about technology. Without techies and the technology they develop, we wouldn’t be able to do the amazing things we do at NASA, or on Earth and in space.

Our Techies

We love our techies! The passionate engineers, researchers and scientists who work on our technology efforts enable us to make a difference in the world around us. They are responsible for developing the pioneering, new technologies and capabilities needed to achieve our current and future missions.

Research and technology development take place within our centers, in academia and industry, and leverage partnerships with other government agencies and international partners. We work to engage and inspire thousands of technologists and innovators creating a community of our best and brightest working on the nation’s toughest challenges.

Technology Drives Exploration

Our investments in technology development enable and advance space exploration. We are continually seeking to improve our ability to access and travel through space, land more mass in more locations, enable humans to live and explore in space and accelerate the pace of discovery.

Techie Technology

Advanced Manufacturing Technologies

When traveling to other planetary bodies, each and every pound of cargo matters. If we can reduce the weight by building tools once we arrive, that’s less weight we need to launch from Earth and carry through space.

Additive manufacturing is a way of printing three-dimensional (3-D) components from a digital model. If you think of a common office printer, it uses a 2-D file to print images and text on a sheet of paper. A 3-D printer uses a 3D file to deposit thin layers of material on top of each other, creating a 3-D product.

Thanks to techies, we’re already using this technology on the International Space Station to print wrenches and other tools. Our Additive Construction for Mobile Emplacement (ACME) project is investigating ways to build structures on planetary surfaces using resources available at a given site.

Discover more about how our techies are working with advanced manufacturing HERE.

Technology Demonstrations

Our techies are always innovating and developing new cutting-edge ideas. We test these ideas in extreme environments both here on Earth and in space.  

Science missions in space require spacecraft propulsion systems that are high-performance, lightweight, compact and have a short development time. The Deep Space Engine project is looking to meet those needs. Our techies are currently testing a 100lbf (pound-force) thruster to see if this compact, lightweight, low-cost chemical propulsion system can operate at very low temperatures, which allows long duration storage capabilities.

Another technology in development is PUFFER, or the Pop-Up Flat Folding Explorer Robot…and it was inspired by origami! This robot’s lightweight design is capable of flattening itself, tucking in its wheels and crawling into places rovers can’t fit. PUFFER has been tested in a range of rugged terrains to explore areas that might be too risky for a full-fledged rover to go.

With our partners at Ball Aerospace & Technologies Corp., we’ve also collaborated on the Green Propellant Infusion Mission (GPIM), which will flight test a "green" alternative to the toxic propellant, hydrazine, in 2018. GPIM is the nation’s premier spacecraft demonstration of a new high-performance power and propulsion system — a more environmentally friendly fuel. This technology promises improved performance for future satellites and other space missions by providing for longer mission durations, increased payload mass and simplified pre-launch spacecraft processing, including safer handling and transfer of propellants.  

Find out more about our technology demonstrations HERE.

Aircraft Technology

What if you could travel from London to New York in less than 3.5 hours? Our techies’ research into supersonic flight could make that a reality! 

Currently, supersonic flight creates a disruptive, loud BOOM, but our goal is to instead create a soft “thump” so that flying at supersonic speeds could be permitted over land in the United States.

We’re conducting a series of flight tests to validate tools and models that will be used for the development of future quiet supersonic aircraft.

Did you know that with the ability to observe the location of an aircraft’s sonic booms, pilots can better keep the loud percussive sounds from disturbing communities on the ground? This display allows research pilots the ability to physically see their sonic footprint on a map as the boom occurs.

Learn more about our aircraft technology HERE.

Technology Spinoffs 

Did you know that some of the technology used in the commercial world was originally developed for NASA? For example, when we were testing parachutes for our Orion spacecraft (which will carry humans into deep space), we needed to capture every millisecond in extreme detail. This would ensure engineers saw and could fix any issues. The problem was,there didn’t exist a camera in the world that could shoot at a high enough frame rate -- and store it in the camera’s memory -- all while adjusting instantly from complete darkness to full daylight and withstanding the space vacuum, space radiation and water immersion after landing.

Oh…and it had to be small, lightweight, and run on low power. Luckily, techies built exactly what we needed. All these improvements have now been incorporated into the camera which is being used in a variety of non-space industries…including car crash tests, where high resolution camera memory help engineers get the most out of testing to make the cars we drive safer.

Learn about more of our spinoff technologies HERE.

Launching the Future of Space Communications

Our newest communications satellite, named the Tracking and Data Relay Satellite-M or TDRS-M, launches Aug. 18 aboard an Atlas V rocket from our Kennedy Space Center in Florida. It will be the 13th TDRS satellite and will replenish the fleet of satellites supporting the Space Network, which provides nearly continuous global communications services to more than 40 of our missions.

Communicating from space wasn’t always so easy. During our third attempt to land on the moon in 1970, the Apollo 13 crew had to abort their mission when the spacecraft’s oxygen tank suddenly exploded and destroyed much of the essential equipment onboard. Made famous in the movie ‘Apollo 13’ by Ron Howard and starring Tom Hanks, our NASA engineers on the ground talked to the crew and fixed the issue. Back in 1970 our ground crew could only communicate with their ground teams for 15 percent of their orbit – adding yet another challenge to the crew. Thankfully, our Apollo 13 astronauts survived and safely returned to Earth. 

Now, our astronauts don’t have to worry about being disconnected from their teams! With the creation of the TDRS program in 1973, space communications coverage increased rapidly from 15 percent coverage to 85 percent coverage. And as we’ve continued to add TDRS spacecraft, coverage zoomed to over 98 percent!

TDRS is a fleet of satellites that beam data from low-Earth-orbiting space missions to scientists on the ground. These data range from cool galaxy images from the Hubble Space Telescope to high-def videos from astronauts on the International Space Station! TDRS is operated by our Space Network, and it is thanks to these hardworking engineers and scientists that we can continuously advance our knowledge about the universe!  

What’s up next in space comm? Only the coolest stuff ever! LASER BEAMS. Our scientists are creating ways to communicate space data from missions through lasers, which have the ability to transfer more data per minute than typical radio-frequency systems. Both radio-frequency and laser comm systems send data at the speed of light, but with laser comm’s ability to send more data at a time through infrared waves, we can receive more information and further our knowledge of space.

How are we initiating laser comm? Our Laser Communications Relay Demonstration is launching in 2019! We’re only two short years away from beaming space data through lasers! This laser communications demo is the next step to strengthen this technology, which uses less power and takes up less space on a spacecraft, leaving more power and room for science instruments.

Watch the TDRS launch live online at 8:03 a.m. EDT on Aug. 18: https://www.nasa.gov/nasalive

New Research Heading to Earth’s Orbiting Laboratory

It’s a bird! It’s a plane! It’s a…dragon? A SpaceX Dragon spacecraft is set to launch into orbit atop the Falcon 9 rocket toward the International Space Station for its 12th commercial resupply (CRS-12) mission August 14 from our Kennedy Space Center in Florida.

It won’t breathe fire, but it will carry science that studies cosmic rays, protein crystal growth, bioengineered lung tissue.

Here are some highlights of research that will be delivered:

I scream, you scream, we all scream for ISS-CREAM! 

Cosmic Rays, Energetics and Mass, that is! Cosmic rays reach Earth from far outside the solar system with energies well beyond what man-made accelerators can achieve. The Cosmic Ray Energetics and Mass (ISS-CREAM) instrument measures the charges of cosmic rays ranging from hydrogen to iron nuclei. Cosmic rays are pieces of atoms that move through space at nearly the speed of light

The data collected from the instrument will help address fundamental science questions such as:

Do supernovae supply the bulk of cosmic rays?

What is the history of cosmic rays in the galaxy?

Can the energy spectra of cosmic rays result from a single mechanism?

ISS-CREAM’s three-year mission will help the scientific community to build a stronger understanding of the fundamental structure of the universe.

Space-grown crystals aid in understanding of Parkinson’s disease

The microgravity environment of the space station allows protein crystals to grow larger and in more perfect shapes than earth-grown crystals, allowing them to be better analyzed on Earth. 

Developed by the Michael J. Fox Foundation, Anatrace and Com-Pac International, the Crystallization of Leucine-rich repeat kinase 2 (LRRK2) under Microgravity Conditions (CASIS PCG 7) investigation will utilize the orbiting laboratory’s microgravity environment to grow larger versions of this important protein, implicated in Parkinson’s disease.

Defining the exact shape and morphology of LRRK2 would help scientists to better understand the pathology of Parkinson’s and could aid in the development of therapies against this target.

Mice Help Us Keep an Eye on Long-term Health Impacts of Spaceflight

Our eyes have a whole network of blood vessels, like the ones in the image below, in the retina—the back part of the eye that transforms light into information for your brain. We are sending mice to the space station (RR-9) to study how the fluids that move through these vessels shift their flow in microgravity, which can lead to impaired vision in astronauts.

By looking at how spaceflight affects not only the eyes, but other parts of the body such as joints, like hips and knees, in mice over a short period of time, we can develop countermeasures to protect astronauts over longer periods of space exploration, and help humans with visual impairments or arthritis on Earth.

Telescope-hosting nanosatellite tests new concept

The Kestrel Eye (NanoRacks-KE IIM) investigation is a microsatellite carrying an optical imaging system payload, including an off-the-shelf telescope. This investigation validates the concept of using microsatellites in low-Earth orbit to support critical operations, such as providing lower-cost Earth imagery in time-sensitive situations, such as tracking severe weather and detecting natural disasters.

Sponsored by the ISS National Laboratory, the overall mission goal for this investigation is to demonstrate that small satellites are viable platforms for providing critical path support to operations and hosting advanced payloads.

Growth of lung tissue in space could provide information about diseases

The Effect of Microgravity on Stem Cell Mediated Recellularization (Lung Tissue) uses the microgravity environment of space to test strategies for growing new lung tissue. The cells are grown in a specialized framework that supplies them with critical growth factors so that scientists can observe how gravity affects growth and specialization as cells become new lung tissue.

The goal of this investigation is to produce bioengineered human lung tissue that can be used as a predictive model of human responses allowing for the study of lung development, lung physiology or disease pathology.

These crazy-cool investigations and others launching aboard the next SpaceX #Dragon cargo spacecraft on August 14. They will join many other investigations currently happening aboard the space station. Follow @ISS_Research on Twitter for more information about the science happening on 250 miles above Earth on the space station.  

Watch the launch live HERE starting at 12:20 p.m. EDT on Monday, Aug. 14!

The Past, Present and Future of Exploration on Mars

Today, we’re celebrating the Red Planet! Since our first close-up picture of Mars in 1965, spacecraft voyages to the Red Planet have revealed a world strangely familiar, yet different enough to challenge our perceptions of what makes a planet work.

You’d think Mars would be easier to understand. Like Earth, Mars has polar ice caps and clouds in its atmosphere, seasonal weather patterns, volcanoes, canyons and other recognizable features. However, conditions on Mars vary wildly from what we know on our own planet.

Join us as we highlight some of the exploration on Mars from the past, present and future:

PAST

Viking Landers

Our Viking Project found a place in history when it became the first U.S. mission to land a spacecraft safely on the surface of Mars and return images of the surface. Two identical spacecraft, each consisting of a lander and an orbiter, were built. Each orbiter-lander pair flew together and entered Mars orbit; the landers then separated and descended to the planet’s surface.

Besides taking photographs and collecting other science data, the two landers conducted three biology experiments designed to look for possible signs of life.

Pathfinder Rover

In 1997, Pathfinder was the first-ever robotic rover to land on the surface of Mars. It was designed as a technology demonstration of a new way to deliver an instrumented lander to the surface of a planet. Mars Pathfinder used an innovative method of directly entering the Martian atmosphere, assisted by a parachute to slow its descent and a giant system of airbags to cushion the impact.

Pathfinder not only accomplished its goal but also returned an unprecedented amount of data and outlived its primary design life.

PRESENT

Spirit and Opportunity

In January 2004, two robotic geologists named Spirit and Opportunity landed on opposite sides of the Red Planet. With far greater mobility than the 1997 Mars Pathfinder rover, these robotic explorers have trekked for miles across the Martian surface, conducting field geology and making atmospheric observations. Carrying identical, sophisticated sets of science instruments, both rovers have found evidence of ancient Martian environments where intermittently wet and habitable conditions existed.

Both missions exceeded their planned 90-day mission lifetimes by many years. Spirit lasted 20 times longer than its original design until its final communication to Earth on March 22, 2010. Opportunity continues to operate more than a decade after launch.

Mars Reconnaissance Orbiter

Our Mars Reconnaissance Orbiter left Earth in 2005 on a search for evidence that water persisted on the surface of Mars for a long period of time. While other Mars missions have shown that water flowed across the surface in Mars’ history, it remained a mystery whether water was ever around long enough to provide a habitat for life.

In addition to using the rover to study Mars, we’re using data and imagery from this mission to survey possible future human landing sites on the Red Planet.

Curiosity

The Curiosity rover is the largest and most capable rover ever sent to Mars. It launched November 26, 2011 and landed on Mars on Aug. 5, 2012. Curiosity set out to answer the question: Did Mars ever have the right environmental conditions to support small life forms called microbes? 

Early in its mission, Curiosity’s scientific tools found chemical and mineral evidence of past habitable environments on Mars. It continues to explore the rock record from a time when Mars could have been home to microbial life.

FUTURE

Space Launch System Rocket

We’re currently building the world’s most powerful rocket, the Space Launch System (SLS). When completed, this rocket will enable astronauts to begin their journey to explore destinations far into the solar system, including Mars.

Orion Spacecraft

The Orion spacecraft will sit atop the Space Launch System rocket as it launches humans deeper into space than ever before. Orion will serve as the exploration vehicle that will carry the crew to space, provide emergency abort capability, sustain the crew during the space travel and provide safe re-entry from deep space return velocities.

Mars 2020

The Mars 2020 rover mission takes the next step in exploration of the Red Planet by not only seeking signs of habitable conditions in the ancient past, but also searching for signs of past microbial life itself.

The Mars 2020 rover introduces a drill that can collect core samples of the most promising rocks and soils and set them aside in a “cache” on the surface of Mars. The mission will also test a method for producing oxygen from the Martian atmosphere, identify other resources (such as subsurface water), improve landing techniques and characterize weather, dust and other potential environmental conditions that could affect future astronauts living and working on the Red Planet.

For decades, we’ve sent orbiters, landers and rovers, dramatically increasing our knowledge about the Red Planet and paving the way for future human explorers. Mars is the next tangible frontier for human exploration, and it’s an achievable goal. There are challenges to pioneering Mars, but we know they are solvable.

Five Ways the International Space Station’s National Lab Enables Commercial Research

A growing number of commercial partners use the International Space Station National Lab. With that growth, we will see more discoveries in fundamental and applied research that could improve life on the ground.

Space Station astronaut Kate Rubins was the first person to sequence DNA in microgravity.

Since 2011, when we engaged the Center for the Advancement of Science in Space (CASIS) to manage the International Space Station (ISS) National Lab, CASIS has partnered with academic researchers, other government organizations, startups and major commercial companies to take advantage of the unique microgravity lab. Today, more than 50 percent of CASIS’ experiments on the station represent commercial research.

Here’s a look at five ways the ISS National Lab is enabling new opportunities for commercial research in space.

1. Supporting Commercial Life Sciences Research

One of the main areas of focus for us in the early origins of the space station program was life sciences, and it is still a major priority today. Studying the effects of microgravity on astronauts provides insight into human physiology, and how it evolves or erodes in space. CASIS took this knowledge and began robust outreach to the pharmaceutical community, which could now take advantage of the microgravity environment on the ISS National Lab to develop and enhance therapies for patients on Earth. Companies such as Merck, Eli Lilly & Company, and Novartis have sent several experiments to the station, including investigations aimed at studying diseases such as osteoporosis, and examining ways to enhance drug tablets for increased potency to help patients on Earth. These companies are trailblazers for many other life science companies that are looking at how the ISS National Lab can advance their research efforts.

2. Enabling Commercial Investigations in Material and Physical Sciences

Over the past few years, CASIS and the ISS National Lab also have seen a major push toward material and physical sciences research by companies interested in enhancing their products for consumers. Examples range from Proctor and Gamble’s investigation aimed at increasing the longevity of daily household products, to Milliken’s flame-retardant textile investigation to improve protective clothing for individuals in harm’s way, and companies looking to enhance materials for household appliances. Additionally, CASIS has been working with a variety of companies to improve remote sensing capabilities in order to better monitor our oceans, predict harmful algal blooms, and ultimately, to better understand our planet from a vantage point roughly 250 miles above Earth.

3. Supporting Startup Companies Interested in Microgravity Research 

CASIS has funded a variety of investigations with small startup companies (in particular through seed funding and grant funding from partnerships and funded solicitations) to leverage the ISS National Lab for both research and test-validation model experiments. CASIS and The Boeing Company recently partnered with MassChallenge, the largest startup accelerator in the world, to fund three startup companies to conduct microgravity research.

4. Enabling Validation of Low-Earth Orbit Business Models 

The ISS National Lab helps validate low-Earth orbit business models. Companies such as NanoRacks, Space Tango, Made In Space, Techshot, and Controlled Dynamics either have been funded by CASIS or have sent instruments to the ISS National Lab that the research community can use, and that open new channels for inquiry. This has allowed the companies that operate these facilities to validate their business models, while also building for the future beyond station.

5. Demonstrating the Commercial Value of Space-based Research

We have been a key partner in working with CASIS to demonstrate to American businesses the value of conducting research in space. Through outreach events such as our Destination Station, where representatives from the International Space Station Program Science Office and CASIS select cities with several major companies and meet with the companies to discuss how they could benefit from space-based research. Over the past few years, this outreach has proven to be a terrific example of building awareness on the benefits of microgravity research.

On June 19, engineers on the ground remotely operated the International Space Station’s robotic arm to remove the Roll-Out Solar Array (ROSA) from the trunk of SpaceX’s Dragon cargo vehicle. Here, you see the experimental solar array unfurl as the station orbits Earth.

Solar panels are an efficient way to power satellites, but they are delicate and large, and must be unfolded when a satellite arrives in orbit. The Roll-Out Solar Array (ROSA) is a new type of solar panel that rolls open in space like a party favor and is more compact than current rigid panel designs.

ROSA is 20% lighter and 4x smaller in volume than rigid panel arrays!

This experiment remained attached to the robotic arm over seven days to test the effectiveness of the advanced, flexible solar array that rolls out like a tape measure. During that time, they also measured power produced by the array and monitored how the technology handled retraction.

10 “Spinoffs of Tomorrow” You Can License for Your Business

The job of the our Technology Transfer Program is pretty straight-forward – bring NASA technology down to Earth. But, what does that actually mean? We’re glad you asked! We transfer the cool inventions NASA scientists develop for missions and license them to American businesses and entrepreneurs. And that is where the magic happens: those business-savvy licensees then create goods and products using our NASA tech. Once it hits the market, it becomes a “NASA Spinoff.”

If you’re imagining that sounds like a nightmare of paperwork and bureaucracy, think again. Our new automated “ATLAS” system helps you license your tech in no time — online and without any confusing forms or jargon.

So, sit back and browse this list of NASA tech ripe for the picking (well, licensing.) When you find something you like, follow the links below to apply for a license today! You can also browse the rest of our patent portfolio - full of hundreds of available technologies – by visiting technology.nasa.gov.

1. Soil Remediation with Plant-Fungal Combinations

Ahh, fungus. It’s fun to say and fun to eat—if you are a mushroom fan. But, did you know it can play a crucial role in helping trees grow in contaminated soil? Scientists at our Ames Research Center discovered that a special type of the fungus among us called “Ectomycorrhizal” (or EM for short) can help enhance the growth of trees in areas that have been damaged, such as those from oil spills.

2. Preliminary Research Aerodynamic Design to Lower Drag

When it comes to aircraft, drag can be, well…a drag. Luckily, innovators at our Armstrong Flight Research Center are experimenting with a new wing design that removes adverse yaw (or unwanted twisting) and dramatically increases aircraft efficiency by reducing drag. Known as the “Preliminary Research Aerodynamic Design to Lower Drag (PRANDTL-D)” wing, this design addresses integrated bending moments and lift to achieve drag reduction.

3. Advancements in Nanomaterials

What do aircraft, batteries, and furniture have in common? They can ALL be improved with our nanomaterials.  Nanomaterials are very tiny materials that often have unique optical, electrical and mechanical properties. Innovators at NASA’s Glenn Research Center have developed a suite of materials and methods to optimize the performance of nanomaterials by making them tougher and easier to process. This useful stuff can also help electronics, fuel cells and textiles.

4. Green Precision Cleaning

Industrial cleaning is hard work. It can also be expensive when you have to bring in chemicals to get things squeaky. Enter “Green Precision Cleaning,” which uses the nitrogen bubbles in water instead. The bubbles act as a scrubbing agent to clean equipment. Goddard Space Flight Center scientists developed this system for cleaning tubing and piping that significantly reduces cost and carbon consumption. Deionized water (or water that has been treated to remove most of its mineral ions) takes the place of costlier isopropyl alcohol (IPA) and also leaves no waste, which cuts out the pricey process of disposal. The cleaning system quickly and precisely removes all foreign matter from tubing and piping.

5. Self-Contained Device to Isolate Biological Samples

When it comes to working in space, smaller is always better. Innovators at our Johnson Space Center have developed a self-contained device for isolating microscopic materials like DNA, RNA, proteins, and cells without using pipettes or centrifuges. Think of this technology like a small briefcase full of what you need to isolate genetic material from organisms and microorganisms for analysis away from the lab. The device is also leak-proof, so users are protected from chemical hazards—which is good news for astronauts and Earth-bound scientists alike.

6. Portable, Rapid, Quiet Drill

When it comes to “bringing the boom,” NASA does it better than anyone. But sometimes, we know it’s better to keep the decibels low. That’s why innovators at NASA’s Jet Propulsion Laboratory have developed a new handheld drilling device, suitable for a variety of operations, that is portable, rapid and quiet. Noise from drilling operations often becomes problematic because of the location or time of operations. Nighttime drilling can be particularly bothersome and the use of hearing protection in the high-noise areas may be difficult in some instances due to space restrictions or local hazards. This drill also weighs less than five pounds – talk about portable power.  

7. Damage Detection System for Flat Surfaces

The ability to detect damage to surfaces can be crucial, especially on a sealed environment that sustains human life or critical equipment. Enter Kennedy Space Center’s damage detection system for flat composite surfaces. The system is made up of layered composite material, with some of those layers containing the detection system imbedded right in. Besides one day potentially keeping humans safe on Mars, this tech can also be used on aircrafts, military shelters, inflatable structures and more.

8. Sucrose-Treated Carbon Nanotube and Graphene Yarns and Sheets

We all know what a spoonful of sugar is capable of. But, who knew it could help make some materials stronger? Innovators at NASA’s Langley Research Center did! They use dehydrated sucrose to create yarns and woven sheets of carbon nanotubes and graphene.

The resulting materials are lightweight and strong. Sucrose is inexpensive and readily available, making the process cost-effective. Makes you look at the sweet substance a little differently, doesn’t it?

9. Ultrasonic Stir Welding

NASA scientists needed to find a way to friction weld that would be gentler on their welding equipment. Meet our next tech, ultrasonic stir welding.

NASA’s Marshall Space Flight Center engineers developed ultrasonic stir welding to join large pieces of very high-strength, high-melting-temperature metals such as titanium and Inconel. The addition of ultrasonic energy reduces damaging forces to the stir rod (or the piece of the unit that vibrates so fast, it joins the welding material together), extending its life. The technology also leaves behind a smoother, higher-quality weld.

10. A Field Deployable PiezoElectric Gravimeter (PEG)

It’s important to know that the fuel pumping into rockets has remained fully liquid or if a harmful chemical is leaking out of its container. But each of those things, and the many other places sensors are routinely used, tends to require a specially designed, one-use device.

That can result in time-consuming and costly cycles of design, test and build, since there is no real standardized sensor that can be adapted and used more widely.

To meet this need, the PiezoElectric Gravimeter (PEG) was developed to provide a sensing system and method that can serve as the foundation for a wide variety of sensing applications.

Space Missions Come Together in Colorado

Our leadership hit the road to visit our commercial partners Lockheed Martin, Sierra Nevada Corp. and Ball Aerospace in Colorado. They were able to check the status of flight hardware, mission operations and even test virtual reality simulations that help these companies build spacecraft parts.

Let’s take a look at all the cool technology they got to see…

Lockheed Martin

Lockheed Martin is the prime contractor building our Orion crew vehicle, the only spacecraft designed to take humans into deep space farther than they’ve ever gone before.

Acting NASA Deputy Administrator Lesa Roe and Acting NASA Administrator Robert Lightfoot are seen inside the CHIL…the Collaborative Human Immersive Laboratory at Lockheed Martin Space Systems in Littleton, Colo. Lockheed Martin’s CHIL enables collaboration between spacecraft design and manufacturing teams before physically producing hardware.

Cool shades! The ability to visualize engineering designs in virtual reality offers tremendous savings in time and money compared to using physical prototypes. Technicians can practice how to assemble and install components, the shop floor can validate tooling and work platform designs, and engineers can visualize performance characteristics like thermal, stress and aerodynamics, just like they are looking at the real thing.

This heat shield, which was used as a test article for the Mars Curiosity Rover, will now be used as the flight heat shield for the Mars 2020 rover mission.

Fun fact: Lockheed Martin has built every Mars heat shield and aeroshell for us since the Viking missions in 1976.

Here you can see Lockheed Martin’s Mission Support Area. Engineers in this room support six of our robotic planetary spacecraft: Mars Odyssey, Mars Reconnaissance Orbiter, MAVEN, Juno, OSIRIS-REx and Spitzer, which recently revealed the first known system of seven Earth-size planets around a single star, TRAPPIST-1. They work with NASA centers and the mission science teams to develop and send commands and monitor the health of the spacecraft.

See all the pictures from the Lockheed Martin visit HERE. 

Sierra Nevada Corporation

Next, Lightfoot and Roe went to Sierra Nevada Corporation in Louisville, Colo. to get an update about its Dream Chaser vehicle. This spacecraft will take cargo to and from the International Space Station as part of our commercial cargo program.

Here, Sierra Nevada Corporation’s Vice President of Space Exploration Systems Steve Lindsey (who is also a former test pilot and astronaut!) speaks with Lightfoot and Roe about the Dream Chaser Space System simulator.

Lightfoot climbed inside the Dream Chaser simulator where he “flew” the crew version of the spacecraft to a safe landing. This mock-up facility enables approach-and-landing simulations as well as other real-life situations. 

See all the images from the Sierra Nevada visit HERE.

Ball Aerospace

Lightfoot and Roe went over to Ball Aerospace to tour its facility. Ball is another one of our commercial aerospace partners and helps builds instruments that are on NASA spacecraft throughout the universe, including the Hubble Space Telescope and the New Horizons mission to Pluto. Ball designed and built the advanced optical technology and lightweight mirror system that will enable the James Webb Space Telescope to look 13.5 billion years back in time. 

Looking into the clean room at Ball Aerospace’s facility in Boulder, Colo., the team can see the Ozone Mapping Profiler Suite. These sensors are used on spacecraft to track ozone measurements.

Here, the group stands in front of a thermal vacuum chamber used to test satellite optics. The Operation Land Imager-2 is being built for Landsat 9, a collaboration between NASA and the U.S. Geological Survey that will continue the Landsat Program’s 40-year data record monitoring the Earth’s landscapes from space.

See all the pictures from the Ball Aerospace visit HERE. 

We recently marked a decade since a new era began in commercial spaceflight development for low-Earth orbit transportation. We inked agreements in 2006 to develop rockets and spacecraft capable of carrying cargo such as experiments and supplies to and from the International Space Station.

5 NASA Software Codes You Can Download – For Free!

One of the biggest steps of any mission starts right here on Earth at a computer desk – NASA runs on software, period. Rovers can’t move, spacecraft can’t fly, even rockets can’t blast off without the software codes that run them all.

We’ve compiled hundreds of these powerful codes into one location at software.nasa.gov. And guess what? You can start downloading them right now for free! Here are just a few you can use:  

1. TetrUSS (Tetrahedral Unstructured Software System)

TetrUSS has been used extensively for space launch vehicle analysis and design, like on the Space Launch System, which is planned to take humans to Mars.

You really could say it's helping us to “blast off.” Outside of NASA, this software has been used to analyze Mars planetary entry vehicles, ballistics and even high-altitude sky diver aerodynamics. Basically if anything has moved through any planetary atmosphere, this software has played a role.

2. KNIFE (part of the FUN3D software and released as a package)

The name may be a bit intimidating, but with good reason – KNIFE packs a powerful punch. 

It was created to help us learn more about the sonic booms that resonate when planes break the sound barrier, but it has also helped develop green energy sources such as wind turbines and techniques to minimize drag for long-haul trucking. Maybe we should re-name this versatile and handy code, “Swiss Army KNIFE?”

3. Cart3D (Automated Triangle Geometry Processing for Surface Modeling and Cartesian Grid Generation)

If software codes went to high school, Cart3D would be Prom Queen. This software is so popular, it is being used in almost every mission area here at NASA. 

Engineers and scientists are currently using it to model everything from advanced drones to quieter supersonic aircraft.

4. FACET (Future Air Traffic Management Concepts Evaluation Tool)

Frequent flyers: this may be your favorite code without even knowing it. FACET was developed to evaluate futuristic concepts in air traffic management, and it has served as a testbed for assessing today’s regular operations. 

To sum it up, this software code helps airports keep planes organized in the air and on the ground.

5. GIPSY-OASIS

GIPSY-OASIS is part of the GPS system to end all GPS systems. It’s so accurate, John Deere used it to help create self-driving tractors.

 How? John Deere already had a navigation system in the works, but it could only be used in certain parts of the world. 

Our ground stations are all across the globe, and our software ensures accuracy down to a few inches. And so, a new breed of tractor was born!  Did we mention this software is free?

These are just a few examples of the software NASA has available for free public and consumer use. To browse the catalog online, check out software.nasa.gov.

Five NASA Technologies at the 2017 Consumer Electronics Show

This week, we’re attending the International Consumer Electronics Show (CES), where we’re joining industrial pioneers and business leaders from across the globe to showcase our space technology. Since 1967, CES has been the place to be for next-generation innovations to get their marketplace debut.

Our technologies are driving exploration and enabling the agency’s bold new missions to extend the human presence beyond the moon, to an asteroid, to Mars and beyond. Here’s a look at five technologies we’re showing off at #CES2017:

1. IDEAS

Our Integrated Display and Environmental Awareness System (IDEAS) is an interactive optical computer that works for smart glasses. The idea behind IDEAS is to enhance real-time operations by providing augmented reality data to field engineers here on Earth and in space. 

This device would allow users to see and modify critical information on a transparent, interactive display without taking their eyes or hands off the work in front of them. 

This wearable technology could dramatically improve the user’s situational awareness, thus improving safety and efficiency. 

For example, an astronaut could see health data, oxygen levels or even environmental emergencies like “invisible” ethanol fires right on their helmet view pane. 

And while the IDEAS prototype is an innovative solution to the challenges of in-space missions, it won’t just benefit astronauts—this technology can be applied to countless fields here on Earth.

2. VERVE

Engineers at our Ames Research Center are developing robots to work as teammates with humans. 

They created a user interface called the Visual Environment for Remote Virtual Exploration (VERVE) that allows researchers to see from a robot’s perspective. 

Using VERVE, astronauts on the International Space Station remotely operated the K10 rover—designed to act as a scout during NASA missions to survey terrain and collect science data to help human explorers. 

This week, Nissan announced that a version of our VERVE was modified for its Seamless Autonomous Mobility (SAM), a platform for the integration of autonomous vehicles into our society. For more on this partnership: https://www.nasa.gov/ames/nisv-podcast-Terry-Fong

3. OnSight

Did you know that we are leveraging technology from virtual and augmented reality apps to help scientists study Mars and to help astronauts in space? 

The Ops Lab at our Jet Propulsion Laboratory is at the forefront of deploying these groundbreaking applications to multiple missions. 

One project we’re demonstrating at CES, is how our OnSight tool—a mixed reality application developed for the Microsoft HoloLens—enables scientists to “work on Mars” together from their offices. 

Supported by the Mars 2020 and Curiosity missions, it is currently in use by a pilot group of scientists for rover operations. Another HoloLens project is being used aboard the International Space Station to empower the crew with assistance when and where they need it.

At CES, we’re also using the Oculus Rift virtual reality platform to provide a tour from the launchpad at our Kennedy Space Center of our Space Launch System (SLS). SLS will be the world’s most powerful rocket and will launch astronauts in the Orion Spacecraft on missions to an asteroid and eventually to Mars. Engineers continue to make progress aimed toward delivering the first SLS rocket to Kennedy in 2018.

4. PUFFER

The Pop-Up Flat Folding Explorer Robot, PUFFER, is an origami-inspired robotic technology prototype that folds into the size of a smartphone. 

It is a low-volume, low-cost enhancement whose compact design means that many little robots could be packed in to a larger “parent” spacecraft to be deployed on a planet’s surface to increase surface mobility. It’s like a Mars rover Mini-Me!

5. ROV-E

Our Remote Operated Vehicle for Education, or ROV-E, is a six-wheeled rover modeled after our Curiosity and the future Mars 2020 Rover. 

It uses off-the-shelf, easily programmable computers and 3D-printed parts. ROV-E has four modes, including user-controlled driving to sensor-based hazard-avoidance and “follow me” modes. ROV-E can answer questions about Mars and follow voice commands.

ROV-E was developed by a team of interns and young, up-and-coming professionals at NASA’s Jet Propulsion Laboratory who wanted to build a Mars rover from scratch to help introduce students and the public to Science, Technology, Engineering & Mathematics (STEM) careers, planetary science and our Journey to Mars.
