I really enjoy Mary Roach's books, so when I was looking for some new audio books, I picked up Packing for Mars. I was not disappointed; it was great.
I have read her other three books, Stiff, Bonk, and Spook, already. I thought Stiff (about cadavers) and Bonk (about sex) were so interesting and funny. I learned a lot. Spook (about the afterlife) was still a good read, but not near as good as the others.
Packing for Mars is about space travel, both in the past and potential for the future. I think one of the best things I can say about this book is that it left me more interested in space and space travel than when I started it. I have always thought that NASA was kind of useless. Now, it makes more sense and I can see its purpose. I read Packing for Mars because it was by Roach, not because I was interested in the topic. However, it really was a fascinating read.
Roach touches on all kind of issues related to space. She covers peeing, sex, and eating. While these issues seem mundane, in space they become very complex. Then there are the complex issues: the effect of g-force on the human body, the feasibility of a human travel to Mars, and even creating space suits to fit a wide range of astronaut body sizes.
If you liked Roach's other books, then definitely pick this up. If you haven't read any of her books, then don't be scared away because this is a non-fiction science book. Her books are very accessible and funny.
