NASA Tech Launching on the Falcon Heavy

Later this month, a SpaceX Falcon Heavy rocket will take to the skies for the third time to launch the Department of Defense’s Space Test Program-2 (STP-2) mission. Several exciting, one-of-a-kind NASA technology and science payloads are among the two-dozen spacecraft aboard.

First, let’s talk about that Falcon Heavy rocket. Its 27 engines generate thrust at liftoff equal to that of approximately 18 airplanes, and it can lift over 140,000 pounds.

Managed by the U.S. Air Force Space and Missile Systems Center, STP-2 is the first government-contracted Falcon Heavy launch. It will reuse the two side boosters recovered after the April flight. SpaceX describes it as one of the most challenging launches in the company’s history.

It’s a big deal to us at NASA because we’re launching some pretty cool technologies. The tech will support our future exploration plans by helping improve future spacecraft design and performance. Here’s a bit about each:

Deep Space Atomic Clock

Time is the heartbeat of space navigation. Today, we navigate in deep space by using giant antennas on Earth to send signals to spacecraft, which then send those signals back to Earth. Atomic clocks on Earth measure the time it takes a signal to make this two-way journey. Only then can human navigators on Earth use large antennas to tell the spacecraft where it is and where to go.

Our Jet Propulsion Laboratory has been perfecting an atomic clock fit for exploration missions. The Deep Space Atomic Clock is the first atomic clock designed to fly on a spacecraft destined for beyond Earth's orbit. The timepiece is lighter and smaller—no larger than a toaster oven—than its refrigerator-sized, Earthly counterparts.

This miniaturized clock could enable one-way navigation: a spacecraft receives a signal from Earth and can determine its location immediately using its own, built-in navigation system. Even smaller versions of the clock are being investigated right now that could be used for the growing number of small to mid-size satellites. As we go forward to the Moon with the Artemis program, precise measurements of time are key to mission success.

The Deep Space Atomic Clock is the primary payload onboard the General Atomics Electromagnetic Systems Orbital Test Bed satellite and will perform a year-long demonstration in space.

Enhanced Tandem Beacon Experiment (E-TBEx)

Two tiny satellites will study how signals can be muddled as they travel through hard-to-predict bubbles in the upper atmosphere. Signals sent from satellites down to Earth (and vice versa) can be disrupted by structured bubbles that sometimes form in Earth's upper atmosphere. Because this region is affected both by weather on Earth and conditions in space, it's hard to predict just when these bubbles will form or how they'll mess with signals.

The E-TBEx CubeSats (short for Enhanced Tandem Beacon Experiment) will try to shed some light on that question. As these little satellites fly around Earth, they'll send radio signals (like the ones used by GPS) to receiving stations on the ground. Scientists will be able to look at the signals received and see if they were jumbled as they traveled through the upper atmosphere down to Earth — which will help us track when these bubbles are forming and how much they're interfering with our signals.

Green Propellant Infusion Mission (GPIM)

For decades, we have relied on a highly toxic spacecraft fuel called hydrazine. The Green Propellant Infusion Mission (GPIM) will lay the foundation to replace conventional chemical propulsion systems with a safer and more efficient alternative for next-generation spacecraft.

GPIM will demonstrate a new propellant in space for the first time. Concocted by the U.S. Air Force Research Laboratory, this innovative, “green” fuel—which actually has more of a peach hue—is expected to improve overall spacecraft performance due to its higher density, increased thrust and lower freezing point in comparison with hydrazine.

GPIM’s propulsion system, developed by Aerojet Rocketdyne, consists of new compatible tanks, valves and thrusters. During the two-month-long demonstration on a Ball Aerospace spacecraft, engineers will conduct orbital maneuvers to demonstrate the performance of the propellant and propulsion system.

Space Environment Testbeds (SET)

It’s not easy being a spacecraft; invisible, energetic particles zip throughout space — and while there are so few that space is considered a vacuum, what’s there still packs a punch. Tiny particles — like those seen here impacting a detector on a Sun-studying spacecraft — can wreak havoc with the electronics we send up into space.

Space Environment Testbeds — or SET, for short — is a mission to study space radiation and how it affects spacecraft and electronics in orbit. What looks like snow flurries in these animated images, for example, is actually a solar radiation storm of incredibly fast particles, unleashed by a solar eruption. Energetic particles from the Sun or deep space can spark memory damage or computer upsets on spacecraft, and over time, degrade hardware.

By studying radiation effects and different methods to protect satellites, SET will help future missions improve spacecraft design, engineering and operations.

CAPSTONE: Testing a Path to the Moon

Before NASA's Artemis astronauts head to the Moon, a microwave oven-sized spacecraft will help lead the way. The Cislunar Autonomous Positioning System Technology Operations and Navigation Experiment, or CAPSTONE, is a CubeSat mission set to launch in spring of 2022. For at least six months, the small spacecraft will fly a unique elongated path around the Moon. Its trajectory—known as a near rectilinear halo orbit—has never been flown before! Once tried and tested, the same orbit will be home to NASA’s future lunar space station Gateway. Here are five things to know:

1. The 55-pound (25 kg) spacecraft is equipped with solar arrays, a camera, and antennae for communication and navigation.

2. Powerful thrusters will help propel the CubeSat toward the Moon.

3. CAPSTONE will fly a unique elongated path around the Moon for at least six months.

4. At its closest approach, it will come within 2,100 miles (3,380 km) of the Moon's North Pole.

5. The same orbit will be home to Gateway— our future outpost for Artemis astronauts heading to the Moon and beyond.

CAPSTONE is commercially owned and operated by Advanced Space in Westminster, Colorado. NASA’s Small Spacecraft Technology program within the agency’s Space Technology Mission Directorate funds the demonstration mission. The program is based at NASA’s Ames Research Center in California’s Silicon Valley. The development of CAPSTONE’s navigation technology is supported by NASA’s Small Business Innovation Research and Small Business Technology Transfer program. The Artemis Campaign Development Division within NASA’s Exploration Systems Development Mission Directorate funds the launch and supports mission operations. The Launch Services Program at NASA’s Kennedy Space Center in Florida manages the launch.

Hi there! Does the study of Earth Science teach us much about the science of other planets? Can much be assumed to be similar, or is the geology/biology incomparable? Thank you!

Build it. Test it. Then, Fly it.

Hundreds of pieces of rockets, rocket engines, boosters, space capsules, launch structures and more have been built, tested and prepared to take us on our Journey to Mars. Across the country, America’s space program is hard at work to launch the Orion space capsule on its first uncrewed flight atop the powerful Space Launch System in 2018.  

But enough of the artist concepts, let’s take a look at the real components being made across the country to prepare for this milestone:

Orion Spacecraft

From testing individual bracket strength to space flight tests, the Orion team is testing every component and subsystem of the spacecraft to ensure crew safety, operational reliability and backup systems are built into the spacecraft from the ground up. To date, hundreds of tests have been conducted across the program to verify and validate that Orion’s design, manufacturing and systems integration meet the rigorous requirements for safe human space exploration.

Orion engineers have subjected the spacecraft to deafening sound blasts, Earthquake-like vibrations and hurricane-force winds in preparation for Orion’s next flight. Large structures such as Orion’s crew and service modules were tested at Lockheed Martin’s Waterton Facility in Littleton, Colorado, and our Glenn Research Center’s Plum Brook Station in Sandusky, Ohio. Motor and engine tests have been conducted at Aerojet Rocketdyne’s facility in Sacramento, California, and Orbital ATK’s facilities in Promontory, Utah, and Elkton, Maryland.

Water impact testing of Orion’s landing capabilities were conducted at our Langley Research Center in Hampton, Virginia, and the capsule’s massive parachute system has been tested in various landing scenarios at the U.S. Army’s Yuma Proving Ground in Arizona. Final assembly, integration and pre-flight testing will take place at our Kennedy Space Center in Florida.

Space Launch System

Towering more than 320 feet, the Space Launch System will be the world’s most powerful rocket. Consisting of a core stage and two boosters, RS-25 engines, and the software to power it all, the initial configuration will provide 15 percent more thrust at launch than the Saturn V rocket and carry more than three times the mass of the Space Shuttle. When complete, we’ll be ready to fire up the largest and most powerful rocket ever built on it’s inaugural launch.

At our Michoud Assembly Facility in New Orleans, a talented crew of humans with the latest in machinery is building SLS’s core stage. The core stage is the structural backbone of SLS that stores cryogenic liquid hydrogen and liquid oxygen that feed the vehicle’s four RS-25 engines. 

For two monumental minutes in June, the SLS solid rocket boosters fired up in an amazing display of power as engineers verified their designs in the last full-scale test before SLS’s first flight. The smoke and fire may last only two minutes, but engineers at NASA’s Marshall Space Flight Center in Huntsville, Alabama, and Orbital ATK in Promontory, Utah, prepared weeks — even months — in advance for that test. 

Launch Site

At our Kennedy Space Center in Florida, teams are hard at work transforming the historic Vehicle Assembly Building for the launches of tomorrow. Like a stairway to the heavens, these upgrades include the building and installation of platforms to access the new Space Launch System rocket. 

Before SLS roars into deep space from Launch Pad 39B, our Ground Systems program continues making significant upgrades and modifications to the historic launch pad to accommodate the new rocket’s shape and size. 

To make room for this new generation of rockets, workers took down the gantry that stood in support of the Space Shuttle program for 30 years and replaced it with, well, not much really. But that was the idea. Whenever SLS heads out to the pad in the future, it's going to bring its support structure with it. With that in mind, Pad 39B will provide all the fluids, electrical, and communications services to the launch platform.

All of this work is essential to get SLS flight ready before it’s maiden voyage and is an important step on our Journey to Mars.

Next Steps

The work happening across the country is preparing us for the first flight of SLS and Orion in 2018. That first, uncrewed test flight is critical to paving the way for future flights that will carry astronauts to deep space, including on a journey to Mars.

Ultimately, the SLS maiden flight will help us prepare for future human missions. During this flight, currently designated Exploration Mission-1, the spacecraft will travel thousands of miles beyond the moon over the course of about a three-week mission.

It will launch on the most powerful rocket in the world and fly farther than any spacecraft built for humans has ever flown. Orion will stay in space longer than any ship for astronauts has done without docking to a space station and return home faster and hotter than ever before.

How did the crews react to you being the first non-astronaut CapCom? I understand it was quite an important thing to people that the CapCom could empathise with their experiences.

In a Warming World, NASA’s Eyes Offer Crucial Views of Hurricanes

June 1 marks the start of hurricane season in the Atlantic Ocean. Last year’s hurricane season saw a record-setting 30 named storms. Twelve made landfall in the United States, also a record. From space, NASA has unique views of hurricanes and works with other government agencies -- like the National Oceanographic and Atmospheric Administration (NOAA) -- to better understand individual storms and entire hurricane seasons.

Here, five ways NASA is changing hurricane science:

1. We can see storms from space

From space, we can see so much more than what’s visible to the naked eye. Among our missions, NASA and NOAA have joint satellite missions monitoring storms in natural color -- basically, what our eyes see -- as well as in other wavelengths of light, which can help identify features our eyes can’t on their own. For instance, images taken in infrared can show the temperatures of clouds, as well as allow us to track the movement of storms at night.

2. We can see inside hurricanes in 3D

If you’ve ever had a CT scan or X-ray done, you know how important 3D imagery can be to understanding what’s happening on the inside. The same concept applies to hurricanes. Our Global Precipitation Measurement mission’s radar and microwave instruments can see through storm clouds to see the precipitation structure of the storm and measure how much total rain is falling as a result of the storm. This information helps scientists understand how the storm may change over time and understand the risk of severe flooding.

We can even virtually fly through hurricanes!

3. We’re looking at how climate change affects hurricane behavior

Climate change is likely causing storms to behave differently. One change is in how storms intensify: More storms are increasing in strength quickly, a process called rapid intensification, where hurricane wind speeds increase by 35 mph (or more) in just 24 hours.

In 2020, a record-tying nine storms rapidly intensified. These quick changes in storm strength can leave communities in their path without time to properly prepare.

Researchers developed a machine learning model that could more accurately detect rapidly intensifying storms.

It’s not just about how quickly hurricanes gain strength. We’re also looking at how climate change may be causing storms to move more slowly, which makes them more destructive. These “stalled” storms can slow to just a few miles an hour, dumping rain and damaging winds on one location at a time. Hurricane Dorian, for example, stalled over Grand Bahama and left catastrophic damage in its wake. Hurricanes Harvey and Florence experienced stalling as well, both causing major flooding.

4. We can monitor damage done by hurricanes

Hurricane Maria reshaped Puerto Rico’s forests. The storm destroyed so many large trees that the overall height of the island’s forests was shortened by one-third. Measurements from the ground, the air, and space gave researchers insights into which trees were more susceptible to wind damage.

Months after Hurricane Maria, parts of Puerto Rico still didn’t have power. Using satellite data, researchers mapped which neighborhoods were still dark and analyzed demographics and physical attributes of the areas with the longest wait for power.

5. We help communities prepare for storms and respond to their aftermath

The data we collect is available for free to the public. We also partner with other federal agencies, like the Federal Emergency Management Agency (FEMA), and regional and local governments to help prepare for and understand the impacts of disasters like hurricanes.

In 2020, our Disasters Program provided data to groups in Alabama, Louisiana, and Central America to identify regions significantly affected by hurricanes. This helps identify vulnerable communities and make informed decisions about where to send resources.

The 2021 Atlantic hurricane season starts today, June 1. Our colleagues at NOAA are predicting another active season, with an above average number of named storms. At NASA, we’re developing new technology to study how storms form and behave, including ways to understand Earth as a system. Working together with our partners at NOAA, FEMA and elsewhere, we’re ready to help communities weather another year of storms.

Bonus: We see storms on other planets, too!

Earth isn’t the only planet with storms. From dust storms on Mars to rains made of glass, we study storms and severe weather on planets in our solar system and beyond. Even the Sun has storms. Jupiter’s Great Red Spot, for instance, is a hurricane-like storm larger than the entire Earth.

Hey! I was wondering how everyone on the ISS adjusts to each other’s culture and language. It seems like it might be hard with language barriers and other factors, to live in a confined space with people from another country. Do others try to teach you their language? Does everyone mostly speak English, or do some people speak Russian?

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.

Student Experiments Soar!

Have you ever wondered what it takes to get a technology ready for space? The NASA TechRise Student Challenge gives middle and high school students a chance to do just that – team up with their classmates to design an original science or technology project and bring that idea to life as a payload on a suborbital vehicle.

Since March 2021, with the help of teachers and technical advisors, students across the country have dreamed up experiments with the potential to impact space exploration and collect data about our planet.

So far, more than 180 TechRise experiments have flown on suborbital vehicles that expose them to the conditions of space. Flight testing is a big step along the path of space technology development and scientific discovery.

The 2023-2024 TechRise Challenge flight tests took place this summer, with 60 student teams selected to fly their experiments on one of two commercial suborbital flight platforms: a high-altitude balloon operated by World View, or the Xodiac rocket-powered lander operated by Astrobotic. Xodiac flew over the company’s Lunar Surface Proving Ground — a test field designed to simulate the Moon’s surface — in Mojave, California, while World View’s high-altitude balloon launched out of Page, Arizona.

Here are four innovative TechRise experiments built by students and tested aboard NASA-supported flights this summer:

1. Oobleck Reaches the Skies

Oobleck, which gets its name from Dr. Seuss, is a mixture of cornstarch and water that behaves as both a liquid and a solid. Inspired by in-class science experiments, high school students at Colegio Otoqui in Bayomón, Puerto Rico, tested how Oobleck’s properties at 80,000 feet aboard a high-altitude balloon are different from those on Earth’s surface. Using sensors and the organic elements to create Oobleck, students aimed to collect data on the fluid under different conditions to determine if it could be used as a system for impact absorption.

2. Terrestrial Magnetic Field

Middle school students at Phillips Academy International Baccalaureate School in Birmingham, Alabama, tested the Earth’s magnetic field strength during the ascent, float, and descent of the high-altitude balloon. The team hypothesized the magnetic field strength decreases as the distance from Earth’s surface increases.

3. Rocket Lander Flame Experiment

To understand the impact of dust, rocks, and other materials kicked up by a rocket plume when landing on the Moon, middle school students at Cliff Valley School in Atlanta, Georgia, tested the vibrations of the Xodiac rocket-powered lander using CO2 and vibration sensors. The team also used infrared (thermal) and visual light cameras to attempt to detect the hazards produced by the rocket plume on the simulated lunar surface, which is important to ensure a safe landing.

4. Rocket Navigation

Middle and high school students at Tiospaye Topa School in LaPlant, South Dakota, developed an experiment to track motion data with the help of a GPS tracker and magnetic radar. Using data from the rocket-powered lander flight, the team will create a map of the flight path as well as the magnetic field of the terrain. The students plan to use their map to explore developing their own rocket navigation system.

The 2024-2025 TechRise Challenge is now accepting proposals for technology and science to be tested on a high-altitude balloon! Not only does TechRise offer hands-on experience in a live testing scenario, but it also provides an opportunity to learn about teamwork, project management, and other real-world skills.

“The TechRise Challenge was a truly remarkable journey for our team,” said Roshni Ismail, the team lead and educator at Cliff Valley School. “Watching them transform through the discovery of new skills, problem-solving together while being driven by the chance of flying their creation on a [rocket-powered lander] with NASA has been exhilarating. They challenged themselves to learn through trial and error and worked long hours to overcome every obstacle. We are very grateful for this opportunity.”

Are you ready to bring your experiment design to the launchpad? If you are a sixth to 12th grade student, you can make a team under the guidance of an educator and submit your experiment ideas by November 1. Get ready to create!
