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

Enjoyable - offbeat, funny, informative, thought-provoking 9 CDs approximately 11 hours Read by Sandra Burr  NASA Artist's conception of a Mars rover The point of Mary Roach's Packing for Mars: The Curious Science of Life in the Void is not the technical challenges of sending an object to Mars. We have demonstrated that we can send a probe to Mars, operate it and do a bit of exploring. No, this is about sending a human to Mars, a much more difficult proposition. Mary Roach deals with the following (and more) in her Packing for Mars : -We eat, drink, and create bodily waste. How do we store enough food to make the trip to Mars? -How do we deal with expelling bodily waste in a zero gravity environment (no toilets - everything would just float out!) -What do we do with the waste? Can you recycle it back into food? Who would want to eat that? -Can people actually live together in cramped quarters for months at a time with no break and not kill
