In January 2022, the Mars Society announced the holding of an international contest for the best design plan of diverse teams of specialized

robots using a 10 metric ton Mars lander, an essential requirement for any human Mars exploration mission. Such systems could first be demonstrated by being used to deliver expeditions consisting of platoons of robots, including wheeled or treaded ground rovers, helicopters, airplanes,balloons, or other types of flight vehicles, and legged robots, including those in humanoid, cat-like, or insectoid forms. Expeditions of this type could return scientific bonanzas while preparing Mars landing sites for human arrival. This book contains the designs of the six finalists in the

competition.
