P13D:
Results from the MAVEN Mission to Mars II


Session ID#: 10388

Session Description:
The Mars Atmosphere and Volatile Evolution (MAVEN) mission went into orbit at Mars in September, 2014.  Its one-Earth-year primary mission will have been completed in November, 2015.  The goal of MAVEN is to understand the structure and composition of the Mars upper atmosphere and ionosphere, the nature of interactions with the solar wind, the current rate of escape of gases to space, and the role played by the solar and solar-wind drivers.  These results will allow us to understand the role played by escape of gas to space in the changes in the Mars climate inferred to have taken place through time.  Preliminary results from the primary mission will be presented.
