Life on Mars If the surface life has been reanimated as recently as 450,000 years ago, then rovers on Mars could find dormant but still viable life at a depth of one meter below the surface, according to an estimate. In 1965, the Mariner 4 probe discovered that Mars had no global magnetic field that would protect the planet from potentially life-threatening cosmic radiation and solar radiation; observations made in the late 1990s by the Mars Global Surveyor confirmed this discovery. Scientists speculate that the lack of magnetic shielding helped the solar wind blow away much of Mars's atmosphere over the course of
Mars Society for testing the innovative balloon system in the low-gravity environment. Test carriers were so far the Airbus A300 for short duration parabolic flights and the sounding rocket test campaigns REXUS3-REGINA and REXUS4-MIRIAM for longer duration flight tests under free space conditions. Further flights tests are planned for the coming years (e.g. MIRIAM II) with the objective of qualifying ARCHIMEDES for its Mars mission by 2018. ARCHIMEDES will be carried to Mars on board an AMSAT Mars Probe or a similar satellite. ARCHIMEDES is developed by the MSD with the support of the Bundeswehr University Munich, of the IABG in Ottobrunn,
