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!

We’re studying a new method of water recycling and carbon dioxide removal that relies on specific geometric shapes and fluid dynamics, rather than complex machinery, in an effort to help build better life support systems for spacecraft. The research could also teach us more about the water processing approaches we take on Earth. Here, NASA astronaut Jack Fischer, is working with the Capillary Structures for Exploration Life Support (Capillary Structures) investigation capillary sorbent hardware that is made up of 3D printed contractors that are supported by tubing, valves and a pump.
Learn more about how this highly interactive investigation works, and what we could learn from the results HERE.

What are three things you would want everyone to know about your work?
Crazyspacesuit: Were you aware of the Overview Effect before experiencing it?
Telescopes located both on the ground and in space continue to dazzle us with incredible images of the universe. We owe these sharp vistas to a series of brilliant astronomers, including Andrea Ghez – an astrophysicist and professor at UCLA – and the “Mother of Hubble,” Nancy Grace Roman.
Did you know that stars don’t actually twinkle? They only look like they do because their light has to travel through our turbulent atmosphere to reach our eyes. As the atmosphere shifts and swirls around, the light from distant stars is slightly refracted, or bent, in different directions. Sometimes it’s directed right at us, but sometimes it’s directed a bit to the side.
It's like someone’s shining a flashlight toward you but moving it around slightly. Sometimes the beam is pointed right at you and appears very bright, and sometimes it's pointed a bit to either side of you and it appears dimmer. The amount of light isn't really changing, but it looks like it is.
This effect creates a problem for ground-based telescopes. Instead of seeing sharp images, astronomers get fuzzy pictures. Special tech known as adaptive optics helps resolve pictures of space so astronomers can see things more clearly. It’s even useful for telescopes that are in space, above Earth’s atmosphere, because tiny imperfections in their optics can blur images, too.
In 2020, Andrea Ghez was awarded a share of the Nobel Prize in Physics for devising an experiment that proved there’s a supermassive black hole embedded in the heart of our galaxy – something Hubble has shown is true of almost every galaxy in the universe! She used the W. M. Keck Observatory’s adaptive optics to track stars orbiting the unseen black hole.
A woman named Nancy Grace Roman, who was NASA’s first chief astronomer, paved the way for telescopes that study the universe from space. An upcoming observatory named in her honor, the Nancy Grace Roman Space Telescope, will use a special kind of adaptive optics in its Coronagraph Instrument, which is a technology demonstration designed to block the glare from host stars and reveal dimmer orbiting planets.
Roman’s Coronagraph Instrument will come equipped with deformable mirrors that will serve as a form of visual "autocorrect" by measuring and subtracting starlight in real time. The mirrors will bend and flex to help counteract effects like temperature changes, which can slightly alter the shape of the optics.
Other telescopes have taken pictures of enormous, young, bright planets orbiting far away from their host stars because they’re usually the easiest ones to see. Taking tech that’s worked well on ground-based telescopes to space will help Roman photograph dimmer, older, colder planets than any other observatory has been able to so far. The mission could even snap the first real photograph of a planet like Jupiter orbiting a Sun-like star!
Find out more about the Nancy Grace Roman Space Telescope on Twitter and Facebook, and learn about the person from which the mission draws its name.

What's a SPOC? Isn't that a star trek character?
How did COVID19 affect your teamwork leading up to the launch? I hope everyone is staying well and sane:)
What does a normal day for you consist of?
Science in the field gets even more delightful. Two different missions are in the field right now, studying snow and how it affects communities around the country.
From our Wallops Flight Facility in Virginia, the IMPACTS mission is flying up and down the East Coast, investigating how snow forms inside clouds. In Grand Mesa, Colorado, SnowEx’s teams on the ground and in the air are taking a close look at how much water is stored in snow.
Hate going out in the storm? The IMPACTS mission can help with that! IMPACTS uses two planes – a P-3 Orion and an ER-2 – flying through and high above the clouds to study where intense bands of snowfall form. Better understanding where intense snow will fall can improve forecast models down the road — helping prepare communities for snowstorms.
Cameras mounted on the wings of the P3 took microscopic images of snowflakes, like this one.
At the same time, the SnowEx team is in Colorado, studying the depth and density of snow. Researchers are making radar spirals with snowmobiles and working in giant snow pits to measure things like snow water equivalent, or how much water is stored in snow.
SnowEx is helping us better understand snow’s role in ecosystems and human systems, like irrigation for agriculture. If you want to bring some corn for popping, SnowEx’s science can help grow that crop.
