Martian Summer: Robot Arms, Cowboy Spacemen, and My 90 Days with the Phoenix Mars Mission is a book written by Andrew Kessler. The book documents Andrew Kessler's three-month stint in mission control of the NASA Phoenix expedition, led by Peter Smith and based at the Lunar and Planetary Laboratory of the University of Arizona. The mission attempted (successfully) to locate evidence of water on Mars.
