On Top of The World – Literally

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!
