In the framework of the ExoMars program, a test campaign was successfully achieved both in Morocco (Erfoud) and in Thales Alenia Space's plant, in Rome. This video underlines tests regarding a key instrument, the Radar Doppler Altimeter (RDA), onboard the descent modules that will land on the Red Planet. This technology concerns both missions: 2016 & 2020. Part of these tests were carried out in Morocco, in the Erfoud-Merzane region, to check the RDAs operation on soil similar to that found on Mars.
