This report is the first part of a systems analysis of the initial phase of manned interplanetary operations. The primary objectives of the first missions are specified and the mission philosophy discussed, in order to set a frame of reference. The importance of brief mission periods is emphasized. Suitable mission profiles to Venus and Mars are presented. A discussion of propulsion systems which can be expected to be available at that time leads to the conclusion that the nuclear heat exchanger system, operating with liquid hydrogen, offers the best compromise within the framework of the mission philosophy outlined. The requirements for the ecological payload, the supporting systems, radiation protection, and the use of scientific payload in the exploration of Venus and Mars are discussed and the resulting weight requirements for the life support system and the scientific payload determined. Finally, design principles for nuclear-powered vehicles are summarized and a prototype layout for fast manned reconnaissance vehicles presented. (Author)
