NASA adjudged Solar-Maximum Mission Smm successful in observing solar flares using five or six experiments simultaneously, coaligning the narrow field-of-view instruments and measuring total solar radiation over at least six months. Launched February 14, 1980, Smm had collected the most data ever on solar flares, about 25 in number, coordinating with groundbased optical and radio telescopes under the International Solar-Maximum Year program. These valuable joint observations would continue. (NASA MOR-S-826-80-O1 [postlaunch] Dec 4/80)
NASA reported successful static-firing for 591 seconds December 4 at NSTL of the main Shuttle propulsion system. The test exceeded the firing time needed to put the Shuttle into Earth orbit. This 11th test of the three-engine cluster brought total test time on the main system to almost 32,000 seconds, in addition to more than 86,400 seconds of tests on individual engines conducted in separate firings.
