I was first introduced to Mary Roach with Stiff: The Curious Lives of Human Cadaversand I quickly fell in love. Roach has the ability to make nonfiction fun and informative. In Packing for Mars: The Curious Science of Life in the Void, Roach tackles life in space. This book is chock full of everything you ever wanted to know about the history of space exploration and a bunch of stuff you never thought about and will never forget. Roach spends a big portion of the book dealing with human digestion and how to deal with it in space. Our bodies don’t work quiet the same in zero gravity as they do on Earth. So eating and everything that comes after have to be dealt with in special ways. Roach details everything from different sized condom-type urine collection bags, to fecal popcorning, to space toilets, to recycling waste into food (highly unpalatable). There are also the problems of how to eat in space and how your clothes break down after going unwashed for weeks. I was not aware that underwear would disintegrate after a couple weeks of constant wear/definitely not something I have had to experience! Roach doesn’t just focus on the absurd and the gross, she is truly fascinated by space travel and has a deep appreciation for those who work in the industry.
