Is outer space like being underwater for astronauts?

None of my friends did space walks (1-2 had training but were awaiting missions). The pressures underwater (depth dependent) are greater than the vacuum of space. The difference between the JSC water tank and a real space walk is the slight resistance water offers. You get wetness with water. read more

Being neutrally buoyant does not stop the blood from rushing to your head or stop your body weight from resting on your shoulders. In the future we may do away with the NBL because it gives a false sense of security because it's not the real thing and the trainers and astronauts expect real space to be exactly like the pool, and it's not. read more

Jessica Meir has been thinking about going to outer space since she was five years old. Now that she's officially a NASA astronaut, Meir is prepping to join the small group of human beings who have left this planet, breaking through our Earth's atmosphere, defying its gravitational pull, and reaching into the stars in search of what's out there. read more

The second is spacesuit and spacewalk training, which utilizes the Neutral Buoyancy Lab (NASA's giant swimming pool), which features a true-to-size underwater space station. Third is the maintenance of the space station itself, so expertise in its life support systems, thermal control, electrical, and basic engineering are an absolute must. read more

The most exciting day for anyone who wants to travel into space is the day he or she is selected to be an astronaut candidate. Then the real work begins. It can take up to two years of training to become a fully qualified astronaut. Candidates must learn the basics of the Space Shuttle and the International Space Station. read more
