The Mars Atmosphere and Volatile Evolution

The Mars Atmosphere and Volatile Evolution (MAVEN) is a future mission, It scheduled for launch in late 2013, it will be the first mission for understanding the Martian upper atmosphere and it contributes for found there sources.The goal of MAVEN is to determine the role that loss of atmospheric gas to space played in changing the Martian climate through time.MAVEN will determine how much of the Martian atmosphere has been lost over time by measuring the current rate of escape to space and gathering enough information about the relevant processes to allow extrapolation backward in time.
