In the early days of the space race, agency researchers in Russia and at NASA really weren't sure all what would happen to an astronaut in space. They didn't know if a human mind could handle actually seeing Earth or what would happen to the human body when exposed to long periods of weightlessness. Would their blood forget which way to pump?
