When the Sun’s magnetic field interacts with Mars, interesting phenomena occur, especially when the local magnetic fields are on the planet’s day-night terminator. One such phenomenon is the acceleration of electrons, which can cause aurora when they interact with the plasma in the planet’s atmosphere. This process often happens in the region “behind” the planet, within the planet’s shadow. This region is called the “magnetotail” because when the Sun’s magnetic field drapes about Mars, it forms a comet-like tail in this shadow region. We study how electrons are accelerated in this region, and present a10-year dataset from one of NASA’s most successful spacecraft: the Mars Atmosphere and Volatile EvolutioN (MAVEN) mission.
