MAVEN: Solar storms speed oxygen loss from Mars atmosphere
In September 2017, a series of moderate to extreme flares jetted outward from the Sun’s surface. Among them was a monster X8.2 class flare that occurred on 10 September and was one of the largest flares of the current, but … Continue reading

MAVEN: Meteoric metal chemistry in Mars’ atmosphere
When dust particles enter the Mars’ atmosphere, collisions with air molecules cause heating and evaporation, and the continuous injection of metal atoms and ions into Mars’ atmosphere. The MAVEN Imaging Ultraviolet Spectrograph, or IUVS, instrument has detected a layer of … Continue reading

How the solar wind interacts with Mars
Mars, without a strong internal dipole magnetic field, is a place where the supersonic solar wind directly contacts the planet’s upper atmosphere. Using a large set of data from the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission, [a paper published … Continue reading
