TL;DR: The Analyzer of Space Plasma and Energetic Atoms (ASPERA) on board the Mars Express spacecraft found that solar wind plasma and accelerated ionospheric ions may be observed all the way down to theMars Express pericenter of 270 kilometers above the dayside planetary surface, implying direct exposure of the martian topside atmosphere toSolar wind plasma forcing.

TL;DR: The ELectron Spectrometer (ELS) from the Analyzer of Space Plasmas and Energetic Atoms (ASPERA-3) flown on the Mars Express spacecraft has an 8% energy resolution, combined with the capability to oversample the martian electron distribution as discussed by the authors.
Journal ArticleDOI
Plasma Acceleration Above Martian Magnetic Anomalies

TL;DR: The Analyzer of Space Plasma and Energetic Atoms experiment on the Mars Express spacecraft has made a detailed study of acceleration processes on the nightside of Mars, observing accelerated electrons and ions in the deep nightside high-altitude region of Mars that map geographically to interface/cleft regions associated with martian crustal magnetization regions.

TL;DR: By identifying peaks in the photoelectron spectrum produced by photoionization of CO2 in the Martian atmosphere, a pilot study was conducted to determine the locations of these photoelectrons in the space around Mars as discussed by the authors.
