This was the year of Mary Roach for me: I had always been hesitant about her books - Bonk seemed to flippant, Stiff irreverant and she was altogether too popular - always a sign that a pop science author doesn't know what she or he is talking about.

So I picked up Packing for Mars because one of my friends was insistent that Mary Roach was actually a great author, and by the title it seemed the least likely to offend, and, to be perfectly honest, there needs to be a new law of physics to describe the force that over time pulls me in to any book on astronomy.

To say I was pleasantly surprised is an understatement. Roach is clearly a scientific writer, rather than a scientist, which is a niche in need of more authors: she writes with a fluidity that is lacking in some popular science books written by scientists, but more than that, she functions in this odd way as an audience surrogate - bringing with her the curiosity (sometimes scatological) of her readers and commenting along the way about her anticipation for meetings, her rationale for her questions and a description of how she finds out the information that she shares. It is a unique authorial voice and one that I enjoyed thoroughly.
The content itself is a complete exploration into the NASA space program - short on hoopla and long on (sometimes scatological) details. Roach is complete, explaining, for instance, every type of food tried, the nutritional assessments, texture and composition of astronaut food, followed up by how it is actually eaten, including concerns about the ability to swallow in space, and which were substantiated and which were not.

Yes, she is a little long on the scatology, but I think that bothers me more than it does the average reader. And while there is a heavy dose of humor, it is mostly witty and tongue-in-cheek, more than gross-out humor. I've been converted: Long live Mary Roach!
