The exploration of the universe remains a challenging endeavor, constantly pushing the limits of technology. Of special interest is the investigation of the other planets of our solar system such as Mars, which has been examined by various teleoperated and (semi-) autonomous satellites and landers. But an important milestone that is needed for a deeper understanding of the planet is still missing: A crewed landing. In order to send humans to such a remote location, an infrastructure for the landing crew including an energy supply, a habitat, and a return vehicle needs to be provided on the surface of the planet. The construction and maintenance of these structures is envisioned to be done by semiautonomous robots that are commanded from orbiting spacecrafts.
