Packing for Mars: The Curious Science of Life in the Void

Roach (Stiff) once again proves herself the ideal guide to a parallel universe. Despite all the high-tech science that has resulted in space shuttles and moonwalks, the most crippling hurdles of cosmic travel are our most primordial human qualities: eating, going to the bathroom, having sex and bathing, and not dying in reentry. Readers learn that throwing up in a space helmet could be life-threatening, that Japanese astronaut candidates must fold a thousand origami paper cranes to test perseverance and attention to detail, and that cadavers are gaining popularity over crash dummies when studying landings. Roach's humor and determined curiosity keep the journey lively, and her profiles of former astronauts are especially telling. However, larger questions about the "worth" or potential benefits of space travel remain ostensibly unasked, effectively rendering these wild and well-researched facts to the status of trivia. Previously, Roach engaged in topics everyone could relate to. Unlike having sex or being dead, though, space travel pertains only to a few, leaving the rest of us unsure what it all amounts to. Still, the chance to float in zero gravity, even if only vicariously, can be surprising in what it reveals about us. (Aug.)
