Mössbauer on Mars
Martian MB data
3426 days (3342 sols) since landing
3406 days (3322 sols) since landing
About our group:
We are using the Mössbauer effect to study minerals, new (artificial) materials, magnetism, implantation effects and surface properties. One of our main activities is the development of different kinds of Mössbauer spectrometers. As one highlight we built a miniaturized backscattering spectrometer, which was sent to planet Mars in the year 2003. It will investigate the mineralogy of the iron containing surface soils and rocks as well as answer questions about the possibility of life on Mars.
Carbonate-Rich Outcrops on Mars identified by the Spirit Rover NASA Rover Finds Clue to Mars Past And Environment for Life
Mössbauer-Group identifies Carbonate-Rich Outcrops on Columbia Hills / Analogy with meteorite ALH 84001
Lengthy detective work with data NASA's Mars Exploration Rover Spirit collected in late 2005 has confirmed that an outcrop called "Comanche" contains a mineral indicating that a past environment was wet and non-acidic, possibly favorable to life. Image credit: NASA/JPL-Caltech/Cornell University

MER Rovers status update:
MER-A 'Spirit'. Gusev Crater. 2011-05-18. Sol 2621-2627.
Spirit Remains Silent at Troy
More than 1,300 commands were radiated to Spirit as part of the recovery effort in an attempt to elicit a response from the rover. No communication has been received from Spirit since Sol 2210 (March 22, 2010). The project concluded the Spirit recovery efforts on May 25, 2011. The remaining, pre-sequenced ultra-high frequency (UHF) relay passes scheduled for Spirit on board the Odyssey orbiter will complete on June 8, 2011. Total odometry is unchanged at 7,730.50 meters (4.80 miles).
MER-B 'Opportunity'. Meridiani Planum. 2011-07-28. Sol 2663-2669.
Opportunity Completes Four Drives: Studies Rock Outcrop
Opportunity is less than 500 meters (0.31 miles) from "Spirit Point," the first landfall on the rim of Endeavour crater. The rover drove four times in the last week on Sols 2663, 2664, 2667 and 2668 (July 22, 23, 26 & 27, 2011), totaling over 460 meters (0.29 miles) of drive distance. The right-front wheel currents remain behaved. On Sol 2669 (July 28, 2011), Opportunity paused in her driving to collect a microscopic imager (MI) mosaic of the surface and an overnight alpha particle X-ray spectrometer (APXS) spectrum of exposed outcrop. The rover also performed a diagnostic test of the MI poker. The results of that test will be received later today. The plan ahead is more driving. As of Sol 2668 (July 27, 2011), solar array energy production was 413 watt-hours with an atmospheric opacity (Tau) of 1.01 and a solar array dust factor of 0.587. Total odometry is 32,973.44 meters (32.97 kilometers, 20.49 miles).
