Former Astronaut about his first Spacewalk
What was your first space walk like? originally appeared on Quora: the place to gain and share knowledge, empowering people to learn from others and better understand the world.
Answer by Leroy Chiao, former NASA astronaut and ISS commander:
„It was a totally new experience, because there is no training that can accurately simulate the feeling and impression. The zero-G airplane flights get you 20 or so seconds at a time of weightlessness, but you don’t get the visual impression of climbing out of the airlock into open space.
Nonetheless, EVA is hard physical work, as your suit is pressurized to keep you alive. Moving your arms and fingers takes strength. Also, it is loud inside of the spacesuit, because of the fan/pump motor(s). It is not at all like in the movies.
