Viking engineers rely on contingency book for Viking mis sions
Viking engineers at Jet Propulsion Laboratory use a detailed contingency manual to manage Mars mission glitches. When Viking 2 orbiter briefly lost contact during descent and a solar power fault caused oscillator wobble, planners employed remote fixes, standby gyros, and taped data to recover the mission.

Venus surface mapped by radar reveals volcanic features
MIT scientist Gordon H. Pettengill and colleagues at the Arecibo Observatory present radar images of Venus showing Maxwell a raised, rough area with long parallel ridges. They suggest volcanic activity or internal processes may shape the surface, implying planetary plate forces similar to Earth. The 4 million square mile area is captured in 12 mile resolution. Venus’s extreme heat and pressure create high winds and cloud cover.
