Planetary science - 1983-1986

Results obtained in the U.S. planetary science programs during 1983-1986 are discussed in a brief review. Topics examined include Halley observations and probes, the flyby of comet Giacobini-Zinner by ISEE-3 (ICE), the Voyager 2 encounter with Uranus, analysis of Voyager 1 and 2 data from the Jupiter and Saturn systems, Pioneer Venus Orbiter observations, theoretical models of lunar evolution, and antarctic meteorites of lunar and perhaps Martian origin.
