Dynamic Test Chamber
NASA's International Sun-Earth Explorer C (ISEE C) was undergoing testing and evaluation inside Goddard's dynamic test chamber when this photo was taken. Working inside a dynamic test chamber, Goddard engineers wear protective "clean room" clothing to prevent microscopic dust particles from damaging the sophisticated instrumentation. NASA launched the 16-sided polyhedron, which weighed 1,032 lbs. (469 kg.), from Cape Canaveral, Florida, on August 12, 1978. From its halo orbit 932,000 miles ( million km.) from Earth, the satellite monitored the characteristics of solar phenomena about one hour before its companion satellites-ISEE-A and ISEE-B-observed the same phenomena from a much closer near-Earth orbit. The correlated measurements supported the work of 117 scientific investigators who were trying to get a better understanding of how the Sun controls Earth's near-space environment. The scientists represented 35 universities in 10 nations.
