Current plans for additional lunar exploration are uncertain.
The Lunar Polar Orbiter (LPO), a spacecraft primarily designed for
systematic geochemical measurements of the surface, is being studied.
Large jumps in knowledge could occur from future planetary
exploration with respect to Venus and the satellites of the outer planets
(Jupiter, Saturn) which are at present largely unknown.
The next few years will see a rapid expansion of our knowledge of
the solar system.
The major events anticipated are as follows:
In addition to the Viking missions previously cited, high public
interest in Viking has stimulated recommendations for another Mars mission
Rovers with a 100 km roam radius and an orbiter equipped
mainly with geochemical sensors and penetrators, and possibly a sample
return, are being considered.
A Venus orbiter imaging radar (VOIR) is needed to study the surface
features of this planet.
This radar has been given the highest ranking by
most science advisory groups and will return high resolution images
(less than 1 km) of most of the planet.
Because Venus is closest to
the Earth in size and composition, this mission, and the 1978 radar
mission to measure mechanical properties of the Venusian surface, have
particular interest to terrestrial geologists. Two GS scientists
are members of the science team.
Two Voyager spacecraft are presently on their way to Jupiter
The satellites of those planets range widely in density and
surface properties, and considerable variations in the geology are
anticipated. Voyager will return several thousand pictures for study
A subsequent mission to orbit Jupiter would provide a more
systematic set of observations than will be possible from Voyager.
The Voyagers, launched in 1977 for an encounter with Jupiter,
will continue on for an encounter with Saturn in 1983.
