DLR Space Operations is the central institution for conducting space missions in Germany. The institution's responsibilities range from satellite missions for Earth observation, communication, and reconnaissance to manned missions and exploration flights into the planetary system. DLR Space Operations also works on new technologies to enable it to master even the most difficult space projects of the future. What to expect In the User Support Center for Space Experiments (MUSC), experiments and missions are prepared, tested, and certified on the ground for their operational use in space and are subsequently conducted in space. At MUSC, both the operation of experimental facilities that utilize microgravity, for example on the International Space Station, and the operation of landers and their payloads for scientific investigations as part of exploration missions within the solar system—such as to planets, asteroids, comets, or moons—are ensured. Through this work, we directly enable scientists to push the boundaries of knowledge.
