The Magellan imagery shows that Venus has a crater abundance equivalent to a surface age of 300 million to 500 million years and a crater distribution close to random. Hence, the tectonics of Venus must be quiescent compared to those of Earth in the last few 100 million years.

VENERA 4, 5 and 6 indicate that the surface layers and atmosphere of Venus are considerably dryer than corresponding regions on Earth. The water content of the atmosphere is in the region of 0.1 to 1 per cent of the total atmospheric gases by volume1, and at the Venus surface temperatures of about 700 K this is very dry indeed.

This report is an introduction to the accompanying collection of initial results from the successful Pioneer Venus orbiter and mutiprobe missions that encountered Venus on 4 December and 9 December 1978, respectively. The mission features are briefly described and furnish data accumulated over the first 30 days of the mission.
