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

To the rocket scientist, you are a problem. You are the most irritating piece of machinery he or she will ever have to deal with. You and your fluctuating metabolism, your puny memory, your frame that comes in a million different configurations. You are unpredictable. You’re inconstant. You take weeks to fix. The engineer must worry about the water and oxygen and food you’ll need in space, about how much extra fuel it will take to launch your shrimp cocktail and irradiated beef tacos. A solar cell or a thruster nozzle is stable and undemanding. It does not excrete or panic or fall in love with the mission commander. It has no ego. Its structural elements don’t start to break down without gravity, and it works just fine without sleep.
