Description:
Numerous questions generated by past Soviet and U.S. Venus missions regarding the climate and history of Venus have stimulated the initiation of a new U.S. program of Venus probes and orbiters. Among the issues that these missions are intended to resolve are the intensity of sunlight reaching the surface of the planet, the extent and composition of the cloud layer, and the mechanisms responsible for the extremely high surface temperatures measured by earlier probes. Also of interest are the reasons for the sharply differing terrains revealed by the Soviet probes Venera 9 and 10. Clarification of such questions may be expected to improve understanding of the origin of life on earth.
