摘要: Abstract The HARP differential electrostatic analyzer measured thermal and supra electron ion fluxes distributions in the Mars environment. High bit-rate data obtained around pericenter passage on elliptical orbits early February 1989 will be highlighted, correlation with results of other experiments discussed. A similarity between total count rate variations spacecraft potential measurements Plasma-Wave System experiment is established. variation energy spectra discussed various regions solar wind interaction Mars. Tentative anisotropy are presented, making use regular ratio rates two sensor heads looking perpendicular directions. Magnetic field MAGMA magnetometer used for comparison.
