“Life in zero gravity is hard to simulate. We practice on the ground what we call…” — Peggy Whitson

Life in zero gravity is hard to simulate. We practice on the ground what we call 'the day in the life' simulations, but it's just practicing some of the tests. It can't prepare you for the fact that all of your tools float if you don't pay attention to where they are! If you don't Velcro things down, they're gonna float away.
