TL;DR: The ASPERA-3 experiment as discussed by the authors was used to study the solar wind interaction and characterize the plasma and neutral gas environment within the space near Mars through the use of energetic neutral atom (ENA) imaging and measuring local ion and electron plasma.

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.

TL;DR: In this article, a single active region produced a series of proton solar flares, with X-ray class up to the X9.0 level, starting on 5 December 2006 at 10:35 UTC, and associated MeV particles were observed at Venus and Mars by Venus Express (VEX) and Mars Express (MEX).
