Study of an imaging experiment planned for the 1973 Mariner Venus/Mercury flyby mission. Scientific objectives are presented together with mission constraints, analysis of alternative systems, and the rationale for the final choice. The final selection was a vidicon camera quite similar to that used for Mariner Mars 1971, but with the capability of real time transmission during the Venus and Mercury flybys. Systematic high resolution UV photography of Venus is planned after encounter in an attempt to understand the nature of the mysterious UV markings and their apparent 4- to 5-day rotation period.
Discussion of Jovian belts, zones and atmospheric features as identified by an analysis of photographs of the planet at the Laboratory. The topics include the circulation of the Jovian atmosphere, the rotation periods of zones and belts, the Great Red Spot shown by methane photographs, and some high altitude photographs of terrestrial atmospheric conditions. Hypothetical mechanisms controlling the atmospheric conditions on Jupiter are considered.

The operation and problems involved with two sky noise meters installed in the Catalina Mountains near Tucson, Arizona are discussed. The instruments were installed at two different locations on Mt. Lemon. It was found that when photometric conditions prevailed, a positive correlation existed between the outputs of the two instruments. In particular, the strongdiurnal effect, in which the sky noise increases abruptly at sunrise and falls markedly after sunset, was reproduced by both instruments. Discrepancies in data recorded by the two instruments are analyzed and possible causes for the discrepancies are proposed.
