Space is a world devoid of the things we need to live and thrive: air,
gravity, hot showers, fresh produce, privacy, beer. Space exploration is
in some ways an exploration of what it means to be human. How much can a
person give up? How much weirdness can they take? What happens to you
when you can't walk for a year? have sex? smell flowers? What happens if
you vomit in your helmet during a spacewalk? Is it possible for the
human body to survive a bailout from space? To answer these questions,
space agencies set up all manner of quizzical and startlingly bizarre
space simulations. As Mary Roach discovers, it's possible to preview
space without ever leaving Earth. From the Space Shuttle training toilet
to a crash test of NASA's new space capsule (cadaver filling in for
astronaut), Roach takes us on a surreally entertaining trip into the
science of life in space and space on Earth.
