The miniaturized Mossbauer (MB) spectrometer MIMOS II is part of the Athena payload of NASA's twin Mars Exploration Rovers 'Spirit' (MER-A) and 'Opportunity' (MER-B). It determines the Fe-bearing mineralogy of Martian soils and rocks at the Rovers' respective landing sites, Gusev crater and Meridiani Planum. Both spectrometers performed successfully during first year of operation. Total integration time is about 49 days for MERA (79 samples) and 34 days for MER-B (85 samples). For curiosity it might be interesting to mention that the total odometry of the oscillating part of the MB drive exceeds 35 km for both rovers.
