Mars flyby and rendezvous with the flyby segment transferring the crew over. (see also Mars Excursion Module (MEM)) Alternately, a flyby-only human mission is also possible, without detaching at Mars, but to slingshot around Mars and back to Earth. In July 1965, Mariner 4 achieved a flyby of Mars with a return of data, providing the public and scientists with dramatically closer images of Mars. During the flyby Mariner 4 took 21 pictures amounting to about 1% of the surface of Mars. Mars was not globally mapped until the Mariner 9 orbiter, which over the course of 1972 to 1973 took thousands
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,
