When I read Mary Roach’s Packing for Mars two thoughts kept coming up: one, that I so wish I’d written the book, and two, that going to space is a royal pain in the ass. I’m amazed anyone has ever wanted to or, in fact, done it. Going to the bathroom alone—a topic Roach delights in investigating in spite of, or perhaps because of, the associated awkwardness—is a major feat in zero gravity. Her book answers all of the practical and embarrassing questions you could ever think to ask about space. Best of all, she gets those answers through correspondence with astronauts and visits to various NASA outposts around the country, as well as a visit to JAXA headquarters.
If you don’t know Roach’s work, do yourself a favor and read one of her books. You’ve got plenty to choose from beyond Packing for Mars. I first found out about her when her first book, Stiff, which examines “the curious lives of human cadavers” made an appearance on Six Feet Under. Her next book, Spook, is all about ghosts and the afterlife. There’s Bonk, which is all about the science of sex and features crazy studies about things such as pig orgasms (and is my favorite of all her books so far), and Gulp, which explores eating and digestion.
