On Top of The World – Literally
What’s one perk about applying to #BeAnAstronaut? You’re one step closer to being on top of the world.
Part of the job of a NASA astronaut is a task called spacewalking. Spacewalking refers to any time an astronaut gets out of a vehicle while in space; it is performed for many reasons such as completing repairs outside the International Space Station, conducting science experiments and testing new equipment.
Spacewalking can last anywhere from five to eight hours, and for that reason, astronauts’ spacesuits are more like mini-spacecraft than uniforms! Inside spacesuits, astronauts have the oxygen they need to breathe, water to drink and a bathroom!
Spacesuits also protect astronauts from the extreme environment of space. In Earth orbit, conditions can be as cold as minus 250 degrees Fahrenheit. In the sunlight, they can be as hot as 250 degrees. A spacesuit protects astronauts from those extreme temperatures.
To stay safe during spacewalks, astronauts are tethered to the International Space Station. The tethers, like ropes, are hooked to the astronaut and the space station – ensuring the astronaut does not float away into space.
Spacewalking can be a demanding task. Astronauts can burn anywhere from ~1500-2500 calories during one full assignment. That’s about equal to running 2/3 of a marathon.
Does spacewalking sound like something you’d be interested in? If so, you might want to APPLY to #BeAnAstronaut! Applications are open until March 31. Don’t miss your chance to!

Leadership, service, being prepared and doing your best – these qualities are exemplified by our astronauts, but are also shared by the Girl Scouts! Our astronaut corps has many scout alumnae, and over the years they’ve been breaking barriers and making names for themselves at NASA.
March 12, 2021 marks the 109th birthday of Girl Scouts in the United States, which has been inspiring generations of girls through leadership and STEM (science, technology, engineering and mathematics) activities to empower the explorers of today and tomorrow. To celebrate, we’re highlighting some of our Girl Scout alumnae over the years!
NASA astronaut and Girl Scout alumna Sunita Williams, who served as an International Space Station commander and spent 322 days in space during two spaceflight expeditions.
Former Scouts have served as crew members on numerous spaceflight missions.
From left: Susan Helms, the first female International Space Station crew member; Eileen Collins, the first woman to pilot and command a space shuttle; and Dr. Kathy Sullivan, the first American woman to perform a spacewalk.
Former Girl Scouts flew on more than one-third of the space shuttle missions and were pioneering forces as women began making their mark on human spaceflight. The first female crew member to serve on the International Space Station, the first to pilot and command a space shuttle and the first American woman to spacewalk were all Scout alumnae.
They continue to break records, such as the first three all-woman spacewalks...
Girl Scout alumnae and NASA astronauts Christina Koch and Jessica Meir made history when they conducted the first ever all-woman spacewalk on Oct.18, 2019. They went on to complete two more spacewalks, successfully completing their task of upgrading the space station’s battery charge/discharge unit. Christina and Jessica’s historic spacewalk was a testament to the growing number of women (and Girl Scouts) joining our astronaut corps; it is a milestone worth celebrating as we look forward to putting the first woman on the Moon with our Artemis Program!
....and the longest spaceflight ever by a woman!
NASA astronaut Christina Koch smiles for a selfie while completing tasks during a spacewalk outside the International Space Station.
Koch went on to seal her name in the record books by surpassing Peggy Whitson’s record for the longest single spaceflight in history by a woman!
Understanding how the human body adjusts to things like weightlessness, radiation and bone-density loss is crucial as we look forward to embarking on long-duration spaceflights to the Moon and Mars. Thanks to former astronaut Scott Kelly’s Year in Space mission, we’ve been able to observe these changes on a biological male. Now, thanks to Christina’s mission, we are able to observe these changes on a biological female.
Girl Scout alumnae will also help lead human exploration farther than ever before as members of our Artemis generation!

On January 10, 2020 we welcomed 11 new astronauts to our ranks – including three Girl Scout alumnae! As part of the first-ever class of astronauts under our Artemis lunar exploration program, Kayla Barron, Jessica Watkins and Loral O’Hara are now qualified for assignments including long-duration missions to the International Space Station, the Moon and Mars.
They took a moment after graduation to share inspiration and insight for current and future Scouts!
Q: A question from the Girl Scouts: What inspires you?
A: “Being a part of an awesome team has always been what inspires me. Whether it’s your Girl Scout troop, a sports team, your class – I think for me always the people around me who push me to succeed and support me when I make mistakes and help me become my best self is what inspires me to show up and do my best.” - NASA astronaut Kayla Barron
Q: How has being a Girl Scout helped you in becoming an astronaut?
A: “Being in the Girl Scouts when I was younger was really cool because, well, first it was just a group of my friends who got to do a lot of different things together. But it really gave us the opportunity to be exposed to a lot of different areas. Like we’d get to go camping. We’d get to ride horses and learn all of these different skills, and so that variety of skill set I think is very applicable to being an astronaut.” - NASA astronaut Loral O’Hara
Q: What would your advice be for the next generation of Girl Scout astronauts?
A: “My advice would be to find something that you’re passionate about. Ideally something in the STEM fields: Science, Technology, Engineering or Mathematics, and to pursue that thing that you’re interested in. Pursue that passion, whatever it is. And don’t give up on your dreams, and continue to follow them until you arrive where you want to be.” - NASA astronaut Jessica Watkins
To all the Girl Scouts out there, keep reaching for the stars because the sky is no longer the limit!

Employee Training – It’s Kind of a Big Deal
This is what it would look like if you were training to #BeAnAstronaut! Astronaut candidates must train for two years before they become official NASA astronauts. After graduation, you can look forward to more skill building when training for upcoming missions. Let’s dive into some of the courses you can expect once you’re selected for the job:
T-38 Jet Training
All astronaut candidates must learn to safely operate in a T-38 jet, either as a pilot or crew. Because this is the one area of their training that is not a simulation and involves decisions with life or death consequences, it teaches them to think quickly and clearly in dynamic situations.
Neutral Buoyancy Lab Training
The mission of the Neutral Buoyancy Lab (NBL) is to prepare astronauts for spacewalking outside the International Space Station! Astronauts are lowered into a large pool wearing full spacesuits. The pool is full of hardware that replicates what the space station is really like, so astronauts are able to practice tasks they can expect on a spacewalk such as going out the airlock, finding a good path to the work site and more! The NBL is beneficial because it gives astronauts the ability to be neutrally buoyant which simulates the effects of microgravity.
Geology Training
Geology training courses are specially tailored to the work astronauts will do from the International Space Station or on the next interplanetary mission! Astronauts learn the basic principles of geology, see rocks in their natural environment and handle samples from their class discussions. It’s less like memorizing the names of rocks and more like learning how geologists think and work.
Wilderness Survival Training
Before they end up in space, astronauts carry out a significant portion of their training in aircraft on Earth. It's unlikely, but possible, that one of those training planes could crash in a remote area and leave the humans on board to fend for themselves for a while. Knowing how to take care of their basic needs would be invaluable. Through the exercises, instructors hope to instill self-care and self-management skills, to develop teamwork skills, and to strengthen leadership abilities – all of which are valuable for working in the isolation of the wild or the isolation of space.
Extreme Environment Training
Astronauts participate in a variety of extreme environment training to prepare for the stresses of spaceflight. Pictured here, they are exploring the underground system of the Sa Grutta caves in Sardinia, Italy as a part of the European Astronaut Centre’s Cooperative Adventure for Valuing and Exercising human behavior and performance Skills (CAVES) expedition. Seasoned astronauts as well as rookies participate in the course and share experiences while learning how to improve leadership, teamwork, decision-making and problem-solving skills.
Virtual Reality Training
In our Virtual Reality Laboratory training facility at Johnson Space Center astronauts are able to immerse themselves in virtual reality to complete mission tasks and robotic operations before launching to space. The facility provides real time graphics and motion simulators integrated with a tendon-driven robotic device to provide the kinesthetic sensation of the mass and inertia characteristics of any large object (<500lb) being handled.

Signs You Might Be Ready to Apply to be a NASA Astronaut
Have you heard the news? Astronaut applications are opening soon (March 2), and there’s never been a better time to apply then now. Here are a few signs that might mean you’re ready to take to the stars:
1. You Don’t Mind Having Roommates
When you’re an astronaut, you have to work and live with your crew mates for extended periods of time. It’s important to the mission and your safety that everyone can collaborate and work together.
2. You LOVE Space
If the Milky Way, planets and space travel doesn’t excite you then this might not be the perfect job for you. But if you love galaxies, space station research and deep space exploration, then maybe you should take a look at our application.
3. Adventure Doesn’t Scare You
Being an astronaut means that you get to take part in adventures that most people will never experience. Imagine: sitting on the launch pad in the Orion spacecraft, atop a rocket that’s getting ready to launch. You’ll travel farther into space than any other humans have been and help push the boundaries of technology in the proving ground of deep space lunar orbits, leading the way for future missions to Mars.
4. You Want to be on the Cutting Edge of Science
Not only do astronauts get to travel to space, but they also get to conduct really cool research in microgravity. Did you know that right now they’re monitoring veggie growth on the International Space Station? This research could help with our future deep space exploration and could teach us a few things about growing plants on Earth. Learn more about all the awesome research on the space station HERE.
5. You’re Not Afraid of Heights
One of the coolest things about being an astronaut, is that you get to go to SPACE! At the very least, you’ll travel to the International Space Station, which is 250 miles above Earth. Or, you could be one of the first astronauts to travel to a distant asteroid or even Mars!
6. You Like Meeting New People
Space is a place where people from all around the world come together to push the boundaries of human exploration. Whether you’re living on the space station with an international crew, or embarking on Artemis missions to the Moon – you’re sure to make new friendships wherever you go.
7. Pizza is Life
Meal time is family time aboard the space station, and what better way to bond than pizza night! Getting to know your crew mates AND channelling your inner chef is always a win win.
8. World Traveling is on Your Bucket List
The International Space Station orbits Earth 16 times a day, so get ready to rack up those frequent flyer miles! A favorite past time of many astronauts is Earth watching from the station’s cupola observatory. Get lost in the Pacific Ocean’s blue hue, gaze at the Himalayas or photograph your favorite cities all from a bird’s eye view. Get assigned to an Artemis Moon mission? Even better! Have fun expanding your travels to the solar system.
9. You’ve Dreamed of Flying
Perk about the job? Your childhood dreams to fly finally come true. Whether you’re floating around the International Space Station or getting adjusted to our new spaceship, Gateway, your inner superhero will be beaming.
10. You Like Helping Others
Astronauts don’t just push the boundaries of human exploration, they also help pave the way for scientific breakthroughs back at home. Thanks to the microgravity environment of space, discoveries not possible on Earth are able to be unlocked. Investigations into Parkinson’s Disease, cancer and more have been conducted on the orbital lab.

How is Biotechnology Preparing us to Live on the Moon and Mars?
The adventures awaiting astronauts on future long-duration missions have technologists researching sustainable ways to live away from Earth. We’re using what we know from almost 20 years of a continuous human presence on the International Space Station and looking at new technologies to prepare for missions to the Moon and Mars.
Biotechnology – technology that uses living organisms to make products that provide a new use – is key to this research.
With biotechnology, we’re developing new ways to manufacture medicines, build habitats and more in space. Here are some ways biotechnology is advancing spaceflight and how the same research is reaping benefits on Earth.
Healthy astronauts
Planning ways to supply food for a multi-year mission on the Moon or Mars may require making food and nutrients in space. Our scientists are testing an early version of a potential solution: get microorganisms to produce vital nutrients like those usually found in vegetables. Then, whenever they’re needed, astronauts can drink them down.
The microorganisms are genetically engineered to rapidly produce controlled quantities of essential nutrients. Because the microorganisms and their food source both have a long shelf-life at room temperature and only need water to be activated, the system provides a simple, practical way to produce essential nutrients on-demand. The same kind of system designed for space could also help provide nutrition for people in remote areas of our planet.
Our researchers are evaluating the first batches of BioNutrient samples that came back to Earth after an experimental run on the International Space Station.
Because space travel takes a toll on the human body, we’re also researching how biotechnology can be used to advance the field of regenerative medicine.
Related cells that are joined together are collectively referred to as tissue, and these cells work together as organs to accomplish specific functions in the human body. Blood vessels around the cells vascularize, providing nutrients to the tissue to keep it healthy.
Our Vascular Tissue Challenge offers a $500,000 prize to be divided among the first three teams that successfully create thick, metabolically-functional human vascularized organ tissue in a controlled laboratory environment. The vascularized, thick-tissue models resulting from this challenge will function as organ analogs, or models, that can be used to study deep space environmental effects, such as radiation, and to develop strategies to minimize the damage to healthy cells.
Plant factories
Humans have relied on plants’ medicinal qualities for thousands of years for everything from alleviating minor ailments to curing serious diseases. Now, researchers are trying to simplify the process of turning plants into medicine (i.e. how to make it compact and portable). If successful, the cost of biomanufacturing pharmaceuticals on Earth could go down, and plants could produce medicines in space.
Creating medicine on demand isn’t something we typically do, so we’re turning to experts in the field for help. Researchers at the University of California, Davis are transforming plants into mini-medicine factories for future Mars missions. They’re genetically altering an ordinary type of lettuce so that it produces a protein called parathyroid hormone. This hormone is an approved drug for treating osteoporosis, a common condition where bones become weak and brittle.
This type of research is important to long duration spaceflight. When astronauts land on Mars, they will have spent more than half a year in zero gravity on the flight there, and they’ll need to be strong and ready to explore. Having the technologies needed to treat that possibility, and other unanticipated health effects of long duration spaceflight, is crucial.
Growing habitats
Vitamins aren’t the only thing astronauts could be growing on Mars; we’re exploring technologies that could grow structures out of fungi.
An early-stage research project underway at our Ames Research Center is prototyping technologies that could "grow" habitats on the Moon, Mars and beyond out of life – specifically, fungi and the unseen underground threads that make up the main part of the fungus. These tiny threads build complex structures with extreme precision, networking out into larger structures like mushrooms. With the right conditions, they can be coaxed into making new structures – ranging from a material similar to leather to the building blocks for a planetary home.
The myco-architecture project envisions a future where astronauts can construct a habitat out of the lightweight fungi material. Upon arrival, by unfolding a basic structure made up of dormant fungi and simply adding water, the fungi would grow around that framework into a fully functional human habitat – all while being safely contained to avoid contaminating the external environment.
Recycling waste
Once astronauts arrive on the surface of the Moon or a more distant planet, they’ll have to carefully manage garbage. This waste includes some stuff that gets flushed on Earth.
Today, we’re already using a recycling system on the space station to turn urine into drinking water. Poop on the other hand is contained then disposed of on spacecraft returning to Earth. That won’t be possible on more distant journeys, so, we’re turning to biomanufacturing for a practical solution.
Biology can serve as an effective recycling factory. Microorganisms such as yeast and algae feed on all kinds of things classified as “mission waste.” Processing their preferred form of nourishment generates products that can serve as raw materials used to make essential supplies like nutrients, medicines, plastic and fuel.
By taking a careful look at biological processes, we hope to develop new, lightweight systems to leverage that biology to do some helpful in-space manufacturing.
From Space to Earth
Biotechnology is preparing us for longer space missions to the Moon and then Mars – farther from Earth than humans have ever traveled before. As we prepare for those exciting missions, we’re also conducting research on the space station for the primary benefit of everyone on Earth.
January is National Biotechnology Month. To learn more about some of the ways NASA is using biotechnology to solve challenges in space and improve life on Earth, visit this link.
