Do Not Go Where The Path May Lead, Go Instead Where There Is No Path And Leave A Trail.  —Ralph Waldo

This Week @ NASA

Astronauts conduct a spacewalk on the International Space Station to prepare it for future activities. Peggy Whitson became the new women’s record holder for number of spacewalks and more!

International Space Station

Work continued aboard the International Space Station. Spacewalkers Shane Kimbrough and Peggy Whitson used the station’s robotic arm to move the Pressurized Mating Adapter-3 on March 24 to move a module to accommodate U.S. commercial spacecraft carrying astronauts on future missions. They continued this work on March 30. Another spacewalk to complete the work is slated for April.

James Webb Space Telescope

Engineers at our Goddard Space Flight Center Center complete vibration and acoustic tesing on the James Webb Space Telescope, which was subjected to earsplitting noice and shaken 50-100 times per second to simulate the rigors of launch.

MAVEN

Data from our MAVEN, our Mars Atmosphere and Volatile EvolutioN, and published in the journal Science, concludes that solar wind and radiation are responsible for stripping Mars of its atmosphere and turning it into the frigid desert world it is today.

Most of the gas ever in the Red Planet’s atmosphere has been lost to space. The MAVEN team focused on the gas argon, estimating that 65% of it has been stripped from the planet. In 2015, the science team determined that atmospheric gas continues to be lost to space.

STEM Education

We participated in a Women’s History Month celebration and the Smithsonian Air and Space Museum. The program feature NASA astronauts and engineers. The were also projects to get girls interested in sciene, technology, engineering and math, or STEM, education. There was also a screening of the film ‘Hidden Figures,’ which relates the story of African-American female mathematicians who were instrumental in the agency’s efforts to launch humans to space.

NASA App on Fire TV

We’ve released our latest free NASA app on a whole new platform--Amazon Fire TV! The app is already available for Apple TV, iOS, and Android.Viewers can stream NASA TV, access 16,000+, download video and more!

The James Webb Space Telescope

Like your backyard telescope, just MUCH more powerful

We’re building the world’s biggest space telescope ever - the James Webb Space Telescope. Webb will look back in time, studying the very first galaxies ever formed. While Webb doesn’t have a tube like your typical backyard telescope, because it's also a reflector telescope it has many of the same parts! Webb has mirrors (including a primary and a secondary) just like a small reflector telescope, only its mirrors are massive (6.5 meters across) and coated in gold (which helps us reflect infrared light).

How does a reflector telescope work? Light is bounced from the primary to the smaller secondary mirror, and then directed to your eye:

Webb works pretty much the same way!

Taking the place of your eye to the eyepiece is a package of science instruments, including cameras and spectrographs, which will capture the light directed into them by the telescope’s mirrors.    

In order to install these instruments, we had to move the telescope structure upside down… an impressive sight!

Once Webb was in place on the assembly stand in the cleanroom, the team at Goddard Space Flight Center installed the instrument module (which we call the ISIM, or Integrated Science Instrument Module), with surgical precision. ISIM has four instruments, three of which were contributed by our partners, the European Space Agency and the Canadian Space Agency. 

All four will detect infrared light from stars and galaxies as far away as 13.6 billion light years. In addition to seeing these first sources of light in the early Universe, Webb will look at stars and planetary systems being formed in clouds of dust and gas. It will also examine the atmospheres of planets around other stars – perhaps we will find an atmosphere similar to Earth’s!

Here is an image with the science instruments being lowered into their spot behind the primary mirror. You can see the golden mirror is face-down.

Here’s another perspective of the instruments being fit into the telescope. 

What you've seen come together above is just the telescope part of the James Webb Space Telescope mission – next comes putting together the rest of the observatory. This includes our massive tennis court-sized sunshield (which acts like the tube-part of your backyard telescope, protecting the mirrors from stray light and heat), as well as the parts that do things like power the telescope and let us communicate with it.

It actually takes several weeks for Webb to completely unfold into its full deployment!

10 Out of this World NASA Spinoff Technologies

What is a spinoff? Great question! A NASA spinoff is a technology, originally developed to meet our mission needs that has been transferred to the public and now provides benefits as a commercial product or service. Basically, we create awesome stuff and then share it with the world. Here’s a list of just a few NASA spinoff technologies (in no particular order): 

1. Enriched Baby Food

While developing life support for Mars missions, NASA-funded researchers discovered a natural source for an omega-3 fatty acid that plays a key role in infant development. The ingredient has since been infused in more than 99% of infant formula on the market and is helping babies worldwide develop healthy brains, eyes and hearts. 

2. Digital Camera Sensors

Whether you take pictures and videos with a DSLR camera, phone or even a GoPro, you’re using NASA technology. The CMOS active pixel sensor in most digital image-capturing devices was invented when we needed to miniaturize cameras for interplanetary missions. 

3. Airplane Wing Designs

Did you know that we’re with you when you fly? Key aerodynamic advances made by our researchers - such as the up-turned ends of wings, called “winglets” - are ubiquitous among modern aircraft and have saved many billions of dollars in fuel costs. 

4. Precision GPS

Uncorrected GPS data can be off by as much as 15 meters thanks to data errors, drift in satellite clocks and interference from Earth’s atmosphere. One of our software packages developed in the 1990s dials in these locations to within centimeters, enabling highly accurate GPS readings anywhere on the planet. One of our most important contributions to modern society, precise GPS is used in everything from personal devices and commercial airplanes to self-driving tractors. 

5. Memory Foam

Possibly the most widely recognized spinoff, memory foam was invented by our researchers looking for ways to keep its test pilots and astronauts comfortable as they experienced extreme acceleration. Today, memory foam cushions beds, chairs, couches, car and motorcycle seats, shoes and even football helmets. 

6. International Search and Rescue System

We pioneered the technology now used internationally for search and rescue operations. When pilots, sailors or other travelers and adventurers are stranded, they can activate a personal locator bacon that uses overhead satellites to relay their call for help and precise location to authorities. 

7. Improvements to Truck Aerodynamics

Nearly every truck on the road has been shaped by NASA - literally. Agency research in vehicle aerodynamic design led to the curves and contours that help modern big rigs cut through the air with less drag. Our contributions to truck design have greatly reduced fuel consumption, perhaps by as much as 6,800 gallons per year for an average vehicle. 

8. Shock Absorbers for Buildings and Bridges

Shock absorbers originally designed to survive the extreme conditions of space shuttle launches are now bracing hundreds of buildings and bridges in earthquake-prone regions all over the world. None of which have suffered even minor damage during an earthquake. 

9. Advanced Water Filtration

We have recently discovered sources of water on the moon and Mars, but even so space is still practically a desert for human explorers, and every drop possible must be recycled and reused. A nanofiber filer devised to purify water in orbit is currently at work on Earth. From devices that supply water to remote villages, to a water bottle that lets hikers and adventurers stay hydrated using streams and lakes, our technology is being utilized. 

10. Invisible Braces

A company working with NASA invented the translucent ceramic that became the first invisible dental braces, which would go on to become one of the best-selling orthodontic products of all time. 

So, now that you know a few of the spinoff technologies that we helped develop, you can look for them throughout your day. Visit our page to learn about more spinoff technologies: https://spinoff.nasa.gov

What ways were used to determine all of the inner workings under our planet Earth’s surface?

Distance: Hazard Far From Home

A human journey to Mars, at first glance, offers an inexhaustible amount of complexities. To bring a mission to the Red Planet from fiction to fact, our Human Research Program has organized some of the hazards astronauts will encounter on a continual basis into five classifications.

The third and perhaps most apparent hazard is, quite simply, the distance.

Rather than a three-day lunar trip, astronauts would be leaving our planet for roughly three years. Facing a communication delay of up to 20 minutes one way and the possibility of equipment failures or a medical emergency, astronauts must be capable of confronting an array of situations without support from their fellow team on Earth.

Once you burn your engines for Mars, there is no turning back so planning and self-sufficiency are essential keys to a successful Martian mission. The Human Research Program is studying and improving food formulation, processing, packaging and preservation systems.

While International Space Station expeditions serve as a rough foundation for the expected impact on planning logistics for such a trip, the data isn’t always comparable, but it is a key to the solution.

Exploration to the Moon and Mars will expose astronauts to five known hazards of spaceflight, including distance from Earth. To learn more, and find out what our Human Research Program is doing to protect humans in space, check out the "Hazards of Human Spaceflight" website. Or, check out this week’s episode of “Houston We Have a Podcast,” in which host Gary Jordan further dives into the threat of distance with Erik Antonsen, the Assistant Director for Human Systems Risk Management at the Johnson Space Center.

10 Technologies That Are Changing the Game

Earlier this year, we hosted a Game Changing Technology Industry Day for the aerospace industry, and in October our engineers and technologists visited Capitol Hill showcasing some of these exciting innovations. Check out these technology developments that could soon be making waves on Earth and in space.

1. Wearable technology

With smartwatches, glasses, and headsets already captivating users around the world, it’s no surprise that the next evolution of wearable technology could be used by first responders at the scene of an accident or by soldiers on a battlefield. The Integrated Display and Environmental Awareness System (IDEAS) is an interactive optical computer that works for smart glasses. 

It has a transparent display, so users have an unobstructed view even during video conferences or while visualizing environmental data. 

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. Every breath they take: life support technologies

Before astronauts can venture to Mars and beyond, we need to significantly upgrade our life support systems. The Next Generation Life Support project is developing technologies to allow astronauts to safely carry out longer duration missions beyond low-Earth orbit. 

The Variable Oxygen Regulator will improve the control of space suit pressure, with features for preventing decompression sickness. The Rapid Cycle Amine technology will remove carbon dioxide and humidity and greatly improve upon today’s current complex system.

3. 3-D printing (for more than just pizza)

New Advanced Manufacturing Technologies (AMT), such as 3-D printing, can help us build rocket parts more quickly and aid in building habitats on other planets. 

These manufacturing initiatives will result in innovative, cost-efficient solutions to many of our planetary missions. Back in 2014, the International Space Station’s 3-D printer manufactured the first 3-D printed object in space, paving the way to future long-term space expeditions. 

The object, a printhead faceplate, is engraved with names of the organizations that collaborated on this space station technology demonstration: NASA and Made In Space, Inc., the space manufacturing company that worked with us to design, build and test the 3-D printer.

4. Spacecraft landing gear

Large spacecraft entering the atmosphere of Mars will be traveling over five times the speed of sound, exposing the craft to extreme heat and drag forces. The Hypersonic Inflatable Aerodynamic Decelerator (HIAD) is designed to protect spacecraft from this environment with an inflatable structure that helps slow a craft for landing. 

To get astronauts and other heavy loads to the surface safely, these components must be very strong. The inflatable consists of a material 15 times stronger than steel, while the thermal protection system can withstand temperatures over 1600°C.

5. From heat shield technology to firefighter shelters

For the Convective Heating Improvement for Emergency Fire Shelters (CHIEFS) project, we partnered with the U.S. Forest Service to develop safer, more effective emergency fire shelters for wild land firefighters. 

Using existing technology for flexible spacecraft heat shields like HIAD, we are building and testing new fire shelters composed of stacks of durable, insulated materials that could help protect the lives of firefighters.

6. Robots and rovers

Real life is looking a bit more like science fiction as Human Robotics Systems are becoming highly complex. They are amplifying human productivity and reducing mission risk by improving the effectiveness of human-robot teams. 

Our humanoid assistant Robonaut is currently aboard the International Space Station helping astronauts perform tasks.

A fleet of robotic spacecraft and rovers already on and around Mars is dramatically increasing our knowledge and paving the way for future human explorers. The Mars Science Laboratory Curiosity rover measured radiation on the way to Mars and is sending back data from the surface. 

This data will help us plan how to protect the astronauts who will explore Mars. 

Future missions like the Mars 2020 rover, seeking signs of past life, will demonstrate new technologies that could help astronauts survive on the Red Planet.

7. Robotic repairs

Currently, a satellite that is even partially damaged cannot be fixed in orbit. Instead, it must be disposed of, which is a lot of potential science lost.

Satellite Servicing technologies would make it possible to repair, upgrade, and even assemble spacecraft in orbit using robotics.

This can extend the lifespan of a mission, and also enable deeper space exploration. 

Restore-L, set to launch in 2020, is a mission that will demonstrate the ability to grab and refuel a satellite.

8. Low-cost spacecraft avionics controllers

Small satellites, or smallsats, are quickly becoming useful tools for both scientists and industry. However, the high cost of spacecraft avionics—the systems that guide and control the craft—often limits how and when smallsats can be sent into orbit by tagging along as payloads on larger launches. 

Using Affordable Vehicle Avionics (AVA) technology, we could launch many more small satellites using an inexpensive avionics controller. This device is smaller than a stack of six CD cases and weighs less than two pounds!

9. Making glass from metal

After a JPL research team of modern-day alchemists set about mixing their own alloys, they discovered that a glass made of metal had the wear resistance of a ceramic, was twice as strong as titanium, and could withstand the extreme cold of planetary surfaces, with temperatures below -150 degrees Fahrenheit.

Bulk Metallic Glass (BMG) gears would enable mechanisms to function without wasting energy on heaters. Most machines need to maintain a warmer temperature to run smoothly, which expends precious fuel and decreases the mission’s science return. 

By developing gearboxes made of BMG alloys, we can extend the life of a spacecraft and learn more about the far reaches of our solar system than ever before. Plus, given their extremely high melting points, metallic glasses can be cheaply manufactured into parts by injection molding, just like plastics.

10. Lighter, cheaper, safer spacecraft fuel tanks

Cryogenic propellant tanks are essential for holding fuel for launch vehicles like our Space Launch System—the world’s most powerful rocket. But the current method for building these tanks is costly and time-consuming, involving almost a mile of welded parts.

Advanced Near Net Shape Technology, part of our Advanced Manufacturing Technologies, is an innovative manufacturing process for constructing cryotanks, using cylinders that only have welds in one area. 

This makes the tank lighter, cheaper, and safer for astronauts, as there are fewer potentially defective welds.

10 Things: Journey to the Center of Mars

May the fifth be with you because history is about to be made: As early as May 5, 2018, we’re set to launch Mars InSight, the very first mission to study the deep interior of Mars. We’ve been roaming the surface of Mars for a while now, but when InSight lands on Nov. 26, 2018, we’re going in for a deeper look. Below, 10 things to know as we head to the heart of Mars.

Coverage of prelaunch and launch activities begins Thursday, May 3, on NASA Television and our homepage.

1. What’s in a name? 

"Insight" is to see the inner nature of something, and the InSight lander—a.k.a. Interior Exploration using Seismic Investigations, Geodesy and Heat Transport—will do just that. InSight will take the "vital signs" of Mars: its pulse (seismology), temperature (heat flow) and reflexes (radio science). It will be the first thorough check-up since the planet formed 4.5 billion years ago.

2. Marsquakes. 

You read that right: earthquakes, except on Mars. Scientists have seen a lot of evidence suggesting Mars has quakes, and InSight will try to detect marsquakes for the first time. By studying how seismic waves pass through the different layers of the planet (the crust, mantle and core), scientists can deduce the depths of these layers and what they're made of. In this way, seismology is like taking an X-ray of the interior of Mars.

Want to know more? Check out this one-minute video.

3. More than Mars. 

InSight is a Mars mission, but it’s also so much more than that. By studying the deep interior of Mars, we hope to learn how other rocky planets form. Earth and Mars were molded from the same primordial stuff more than 4.5 billion years ago, but then became quite different. Why didn’t they share the same fate? When it comes to rocky planets, we’ve only studied one in great detail: Earth. By comparing Earth's interior to that of Mars, InSight's team hopes to better understand our solar system. What they learn might even aid the search for Earth-like planets outside our solar system, narrowing down which ones might be able to support life.

4. Robot testing. 

InSight looks a bit like an oversized crane game: When it lands on Mars this November, its robotic arm will be used to grasp and move objects on another planet for the first time. And like any crane game, practice makes it easier to capture the prize.

Want to see what a Mars robot test lab is like? Take a 360 tour.

5. The gang’s all here. 

InSight will be traveling with a number of instruments, from cameras and antennas to the heat flow probe. Get up close and personal with each one in our instrument profiles.

6. Trifecta. 

InSight has three major parts that make up the spacecraft: Cruise Stage; Entry, Descent, and Landing System; and the Lander. Find out what each one does here.

7. Solar wings. 

Mars has weak sunlight because of its long distance from the Sun and a dusty, thin atmosphere. So InSight’s fan-like solar panels were specially designed to power InSight in this environment for at least one Martian year, or two Earth years.

8. Clues in the crust. 

Our scientists have found evidence that Mars’ crust is not as dense as previously thought, a clue that could help researchers better understand the Red Planet’s interior structure and evolution. “The crust is the end-result of everything that happened during a planet’s history, so a lower density could have important implications about Mars’ formation and evolution,” said Sander Goossens of our Goddard Space Flight Center in Greenbelt, Maryland.

9. Passengers. 

InSight won’t be flying solo—it will have two microchips on board inscribed with more than 2.4 million names submitted by the public. "It's a fun way for the public to feel personally invested in the mission," said Bruce Banerdt of our Jet Propulsion Laboratory, the mission's principal investigator. "We're happy to have them along for the ride."

10. Tiny CubeSats, huge firsts. 

The rocket that will loft InSight beyond Earth will also launch a separate NASA technology experiment: two mini-spacecraft called Mars Cube One, or MarCO. These suitcase-sized CubeSats will fly on their own path to Mars behindInSight. Their goal is to test new miniaturized deep space communication equipment and, if the MarCOs make it to Mars, may relay back InSight data as it enters the Martian atmosphere and lands. This will be a first test of miniaturized CubeSat technology at another planet, which researchers hope can offer new capabilities to future missions.

Celebrating 81 Years of Ingenuity

Eighty-one years ago, our world-class research center in California’s Silicon Valley was born. Ground broke on Ames Research Center on Dec. 20, 1939. It was the second aeronautical laboratory established by the National Advisory Committee for Aeronautics to perform fundamental research on all things flight. From its very beginnings, Ames was a place for innovation. Tests performed in its wind tunnels transformed military aircraft during World War II and paved the way for air travel at supersonic speeds. In the 1950s and ‘60s, its researchers looked to the stars and came up with new designs and materials for spacecraft that would make human spaceflight a reality. Fast-forward to the present, and the center contributes to virtually every major agency mission through its expertise in spacecraft entry systems, robotics, aeronautics, supercomputing, and so much more! Here are things to know about Ames.

Ames Research Center is home to the world’s largest wind tunnel.

The center is also home to Pleiades, our most powerful supercomputer.

Its modeling and simulation work plays a key role in designing new vehicles for exploring space.

The center invented heat shield materials for landing rovers on Mars.

It built robots to assist astronauts living and working aboard the International Space Station.

It launched a space telescope that revealed thousands of worlds beyond our solar system.

The center has also led multiple missions to explore the Moon.

It found water on the Moon ... more than once, and in places no one would have guessed.

The Volatiles Investigating Polar Exploration Rover is the latest lunar exploration mission led by Ames. Launching in 2023, the mobile robot will search for water ice inside craters and other places at the Moon's South Pole. Its survey will help pave the way for astronaut missions to the lunar surface beginning in 2024 as part of the Artemis program.

Touchdown! 

A Soyuz spacecraft is seen as it lands with astronaut Shane Kimbrough of NASA and Russian Flight Engineers Sergey Ryzhikov and Andrey Borisenko near the town of Zhezkazgan, Kazakhstan on Monday, April 10. Kimbrough, Ryzhikov, and Borisenko are returning after 173 days in space onboard the International Space Station. 

While living and working aboard the space station, the crew members contributed to hundreds of experiments in biology, biotechnology, physical science and Earth science aboard the world-class orbiting laboratory. For example, the Microgravity Expanded Stem Cells investigation had crew members observe cell growth and other characteristics in microgravity. 

Results from this investigation could lead to the treatment of diseases and injury in space, and provide a way to improve stem cell production for medical therapies on Earth. Photo Credit: (NASA/Bill Ingalls)
