The book: "Packing For Mars" by Mary Roach
 

The best-selling author of "Stiff" and "Bonk" explores the irresistibly strange universe of space travel and life without gravity.

Space is a world devoid of the things we need to live and thrive: air, gravity, hot showers, fresh produce, privacy, beer. Space exploration is in some ways an exploration of what it means to be human. How much can a person give up? How much weirdness can they take? What happens to you when you can't walk for a year? have sex? smell flowers? What happens if you vomit in your helmet during a spacewalk? Is it possible for the human body to survive a bailout from space? To answer these questions, space agencies set up all manner of quizzical and startlingly bizarre space simulations. As Mary Roach discovers, it's possible to preview space without ever leaving Earth. From the Space Shuttle training toilet to a crash test of NASA's new space capsule (cadaver filling in for astronaut), Roach takes us on a surreally entertaining trip into the science of life in space and space on Earth.

This sounds inviting

I read her book "Bonk" and loved it.

I read her book "Stiff" and found it very interesting and at the present time I'm reading her new book, "Gulp".

Anything - or anywhere - that takes me away from the reach of the IRS can't be bad.

The Mars thing is a go.
