The solar wind is greatly accelerating the release of oxygen ions from the Martian atmosphere

The solar wind is greatly accelerating the release of oxygen ions from the Martian atmosphere

A new high resolution/high performance computing model developed by the Finnish Meteorological Institute shows in detail how the solar wind is stripping oxygen from the upper atmosphere of Mars.

This was based on the findings of the European Space Agency Mars Express probe and the NASA's Mars Atmosphere and Volatile EvolutioN (MAVEN) probes to study the erosion of the Martian atmosphere. The follow-up work focused on comparing the model successfully not only with the probe observations but also other models relating to the escape of oxygen from the Martian atmosphere within the context of an international modelling challenge.
