MAVEN reveals speed of solar wind stripping Martian atmosphere

6 November 2015 Astronomy Now

NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission has identified the process that appears to have played a key role in the transition of the Martian climate from an early, warm and wet environment that might have supported surface life to the cold, arid planet Mars is today. Researchers have determined the rate at which the Martian atmosphere is losing gas to space via stripping by the solar wind and that the erosion increases significantly during solar storms.
