Have you ever wondered what it's really like for an astronaut in outer space? From the exciting moments to the day-to-day details, from the serious to the humorous, you'll find answers to every question you've ever had about living in space! What does it feel like to be weightless? Would a sneeze propel you backward? What happens to your body in space? And, most importantly, how do you go to the bathroom in space? Find out the answers from the astronaut who for more than a decade held the world record for the number of days spent living in space! To take advantage of the renewed interest in space travel, thanks to the success of Packing for Mars, this re-release of the bestseller (with over a quarter million copies in print) features a fresh look, dozens of authentic NASA photographs, and an introduction by John Glenn.
