Life on Mars life were found. Mariner 4 probe performed the first successful flyby of the planet Mars, returning the first pictures of the Martian surface in 1965. The photographs showed an arid Mars without rivers, oceans, or any signs of life. Further, it revealed that the surface (at least the parts that it photographed) was covered in craters, indicating a lack of plate tectonics and weathering of any kind for the last 4 billion years. The probe also found that Mars has no global magnetic field that would protect the planet from potentially life-threatening cosmic rays. The probe was able to calculate
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,
