MAVEN Mission

NASA's MAVEN mission is investigating the mystery of how ancient Mars went from being a wet world to the cold, dry desert it is now. The MAVEN (short for Mars Atmosphere and Volatile Evolution) probe will investigate the Red Planet's thin atmosphere, searching for signs of how the planet became what it is today. See the latest MAVEN news, photos and video here.
