In-Situ Determination of the Iron Mineralogy of the Surface of Mars — •Goestar Klingelhoefer1, Bodo Bernhardt1, Ralf Gellert1, Beatrix Mueller1, Josef Foh1, Uwe Bonnes2, Egbert Kankeleit2, Slava Linkin3, Evgeny Evlanov3, Boris Zubkov3, and Claude d’Uston4 — 1Universitaet Mainz, Inst.Anorg.u.Analyt.Chemie, 55099 Mainz — 2Inst.f.Kernphysik, Universitaet Darmstadt — 3Space Research Institut IKI, Moscow, Russia — 4CESR, Toulouse, France
The miniaturized Moessbauer Spectrometer MIMOS II as part of the scientific payload of the US-American Mars missions Mars-Surveyor 2001 and 2003 will be used to determine the Iron bearing minerals and the (Fe2+)/(Fe3+) ratio of the surface material of the planet Mars. The instrument MIMOS II, originally developed for the Russian space mission Mars-98, has a total weight of less than 500 g and a power consumption of about 2-3 Watts. It consists of a sensor head and the electronics board with the instrument control unit. The obtained information on minerals, weathering products, and oxidation state will significantly contribute to the understanding of the history of water on the surface of Mars, and the possible evolution of life on Mars.
The project is funded by the German Space Agency DLR.
