Access of solar wind electrons into the Martian magnetosphere

Barabash, S.; Lundin, R.; Winningham, J. D. +7 more

Electrons with energy of ~40 80 eV measured by the instrument ASPERA-3 on Mars Express and MAG-ER onboard Mars Global Surveyor are used to trace an access of solar wind electrons into the Martian magnetosphere. Crustal magnetic fields create an additional protection from solar wind plasma on the dayside of the Southern Hemisphere by shifting the b…
