AbstractAs a result of studies undertaken during 1981 and 1982, in support of NASA's Solar System Exploration Committee activities, several new approaches have been identified for development of flight hardware as well as ground systems for the execution of U.S. planetary missions through the close of the century. This paper will summarize these new approaches for achieving lower cost in planetary exploration in three different ways: • Use of modified “production line” spacecraft developed by aerospace companies for scientific and commercial use in earth orbit—study results will be discussed which demonstrate that with only modest modifications to existing earth orbiting spacecraft, excellent results can be expected at planetary targets in the inner solar system ranging from Venus to the inner portions of the asteroid belt. Use of both communications satellites typical of those used in geosynchronous applications, as well as low earth orbiting scientific and meteorological satellites will be discussed. The range of changes and the rationale for these changes required to perform planetary missions will be displayed in detail.• The development of a multi-mission modular type spacecraft for planetary missions—a new approach and new flexible spacecraft design proposed for development for planetary missions to comets, main-belt asteroids, and the outer planets will be identified. This Mariner Mark II spacecraft will enable reconfiguration at low cost for adaptation to a wide range of missions. Design concepts which draw heavily on early planetary missions as well as technology developments that are expected to be available in the late 80's and early 90's will be described in detail.• Development of low-cost multi-mission end-to-end information system—a system design including spacecraft command and data handling system requirements, as well as an architecture for a cost effective multi-mission operations system will be described. This system is intended to be applied to both classes of spacecraft/missions described above.
