In Roach's first book, despite her hysterical dark humor about an awkward subject (cadavers), I never felt she crossed a line of disrespect or tastefulness. I can't say that with Packing for Mars. On occasion she seemed more concerned with making her next dick or poop joke than discussing the actual science. At times, I felt it was gratuitous.
But that's a minor quibble in an otherwise enjoyable book about a subject we may well be hearing a lot more about if America (or a joint enterprise) puts a manned-mission to Mars back on the table. I'm with Roach. It would cost roughly what we spent on the Iraq war. Don't even pretend to tell me a Mars expedition would be wasted money after that!
from the publisher: The best-selling author of Stiff and Bonk explores the irresistibly strange universe of space travel and life without gravity. From the Space Shuttle training toilet to a crash test of NASA's new space capsule, Mary Roach takes us on a surreally entertaining trip into the science of life in space and space on Earth.
