 This documentary, hosted by Skylab astronaut Bill Pogue, shows us what it is like to live, work, and play in a zero-gravity environment. Changes to the human body and personal appearance brought on by zero-g, eating, drinking, exercising, sleeping, bathing, personal hygiene and waste elimination, housekeeping, moving around, working (including spacewalks), playing, celebrating holidays, viewing Earth from space, and adapting back to normal gravity are all discussed in detail, using NASA footage of space missions from Mercury to the Shuttle.
