Fig. 1From: In situ observations of ions and magnetic field around Phobos: the mass spectrum analyzer (MSA) for the Martian Moons eXploration (MMX) missionSecondary ion ratios for several types of meteorites considering the solar wind and Martian magnetospheric ion sputtering. Solar wind fluxes were calculated assuming 95% H+ and 5% He++ ions, and incident ion fluxes for the various magnetosphere regions were determined from MAVEN STATIC observations combined with SDTrimSP sputtering simulations and experimental calibration of relative secondary ion yields (Schaible et al. 2017)Back to article page
