SPACE.com: A new NASA unmanned spacecraft destined for Mars is scheduled to launch in 2013. The Mars Atmosphere and Volatile Evolution mission, called “Maven” for short, will cost $438 million and will study Mars’s atmosphere. “Maven will examine all known ways the sun is currently swiping the Martian atmosphere, and may discover new ones as well,” said Joseph Grebowsky, the mission’s project scientist at NASA’s Goddard Space Flight Center.
