MAVEN Mission Reveals Speed of Solar Wind Stripping Martian Atmosphere

Scientists involved in NASA’s Mars Atmosphere and Volatile Evolution (MAVEN) mission, which is being led by the LASP team at the University of Colorado Boulder, have 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.

MAVEN data have enabled researchers to determine the rate at which the Martian atmosphere currently is losing gas to space via stripping by the solar wind. The findings reveal that the erosion of Mars’ atmosphere increases significantly during solar storms. The scientific results from the mission appear in the Nov. 5 issues of the journals Science and Geophysical Research Letters.
