Packing for Mars

What happens to you when you cant walk for a year? When you cant have sex? Or smell flowers? What happens if you vomit in your helmet during a space walk? Is it possible to survive a bailout at 17,000 miles an hour? Space is a world devoid of the things we need to live and thrive: air, gravity, hot showers, fresh veg, privacy, beer. To answer these questions, space agencies set up all manner of quizzical and startlingly bizarre space simulations, and as Mary Roach discovers, its possible to preview space without ever leaving Earth. Packing for Mars takes us on a surreally entertaining voyage into the science of life in space and space on Earth.
