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
A quantitative model of the planetary Na + contribution to Mercury’s magnetosphere
Dominique Delcourt,S. Grimald,François Leblanc,Jean-Jacques Berthelier,A. Millilo,Alessandro Mura,Stefano Orsini,Thomas E. Moore +7 more
TL;DR: In this article, the circulation of heavy ions of planetary origin within Mercury's magnetosphere was examined using single particle trajectory calculations, focusing on the dynamics of sodium ions, one of the main species that are ejected from the planet's surface.
Journal ArticleDOI

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 paper, the mass composition of escaping ion species at Mars was analyzed using data from the ion mass analyzer (IMA) sensor of the ASPERA-3 instrument suite on Mars Express.
Journal ArticleDOI
Mapping of the cusp plasma precipitation on the surface of Mercury
Stefano Massetti,Stefano Orsini,Anna Milillo,Alessandro Mura,E. De Angelis,Helmut Lammer,Peter Wurz +6 more
TL;DR: In this paper, the shape and dimension of the open magnetic field regions (cusps) that allow the direct penetration of magnetosheath plasma through the exosphere of Mercury, down to its surface, were investigated.
