"Mars, the most habitable of our sister planets, holds a special place in our imaginations and in our space exploration program. Fully half of NASA’s planetary exploration effort is now devoted to Mars. Key questions include: Has Mars ever harbored life? Is there life on Mars now? Will humans be able to survive the martian surface? Answers to these questions lie in determining the present location of water on Mars and its likely inventory in the past, and in determining the present radiation environment of Mars. This book captures the objectives, the design of the 2001 Mars Odyssey Mission and the details of the instruments carried to Mars".
