MAVEN (Mars Atmospheric and Volatile EvolutioN) is a satellite designed to investigate the dramatic climatic change the planet has experienced. Though Mars once held liquid surface water, the dense atmosphere that supported it was lost to space long ago. MAVEN will look at the area around the planet to observe how quickly the atmosphere is currently being lost to help infer what might have happened in the past.
Built by Lockheed Martin with science operations under the direction of Bruce Jakosky of the University of Colorado, MAVEN arrived in Martian orbit on September 21st, 2014. Its mission will involve a series of elliptical orbits dipping into the upper atmosphere of Mars to directly sample the gas and ion composition there. The outer solar array panels are angled slightly inward to make the satellite more stable during these operations.
