Sunita Williams breaks a 5.5-hour spacewalk record after forgetting how to walk in space
After spending nearly 7 months in zero gravity, astronaut Sunita Williams overcame the challenge of re-learning to walk, then set a record with a 5.5-hour spacewalk. Along with Butch Willmore, Williams smashed Peggy Whitson's record for total spacewalk time at the International Space Station and conducted vital experiments on microbial survival in space.
