The plasma Environment of Mars

TL;DR: For a number of years significant uncertainties have existed concerning the nature of the solar wind interaction at Mars, because of the lack of relevant plasma and field observations as discussed by the authors, but the results of the Phobos-2 and Mars Global Surveyor (MGS) spacecraft, with different instrument complements and orbital parameters, led to a significant improvement of our knowledge about the regions and boundaries surrounding Mars.
Journal ArticleDOI

Solar Wind-Induced Atmospheric Erosion at Mars: First Results from ASPERA-3 on Mars Express

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.
Journal ArticleDOI

The loss of ions from Venus through the plasma wake

TL;DR: Measurements of the atmosphere of Venus show that the dominant escaping ions are O+, He+ and H+.
Journal ArticleDOI

Charge exchange near Mars: The solar wind absorption and energetic neutral atom production

TL;DR: In this article, an empirical proton model derived from Phobos 2 observations interacting with the Martian atomic (H) and molecular (H2) hydrogen, and oxygen (O) upper atmospheres representing solar minimum and solar maximum conditions is presented.
