In a video posted to twitter, NASA astronaut Drew Feustel showed his attempt to walk heel-to-toe with his eyes closed after over six months in space. Surrounded by a team of researchers, Feustel stumbles forward looking much worse than a drunk person trying to pass a field sobriety test. The best comparison is like a baby giraffe learning to use it’s long legs.
Feustel spent his time on the International Space Station (ISS), floating around with only a weak gravitational pull. To challenge the loss of bone density and muscle mass, astronauts spend two hours a day exercising on modified equipment.If you find this interesting, check out NASA’s twin study with astronauts Scott and Mark Kelly where Scott spent a year in space to determine the long-term effects on the body.
