Ask An Astronaut - Challenges of Microgravity
Clip: Season 1000 | 1m 1s
Have you ever wondered what it's like to live and work in space? We certainly did, so we asked NASA Astronaut, Colonel Doug Wheelock, who has spent more than 178 days in space at the International Space Station to tell us about his experience for a series we're calling "Ask An Astronaut." This time, Col. Wheelock tells us how tough it can be to live and work in a microgravity environment.
