A major objective of missions to Mars will be to conduct reconnaissance and to explore the surface. Systems that will allow astronauts to operate freely in the Martian environment are discussed. Special consideration is given to the design of manned rovers and to the safety and science issues involved. To conduct a wide-ranging exploration, a sortie time of at least 7 Martian days and an adequate fuel/power source are needed for at least a 100-km range. The concept of a hybrid rover is proposed, that will fulfill these requirements. In the Hybrid Rover, the driver of the vehicle will transport a space-suit-wearing astronaut to the area of interest, where the 'suitman' will demount and conduct typical field geological exploration, while the driver will continue to reconnoiter the area, and/or conduct independent sampling sorties using manipulator arms. Attention is also given to the design of a life support system. For fulfilling the power requirements of transportation and a power-intensive closed-cycle life supporting system, nuclear power is being considered as one of the possible power sources.
