In this historical photo from the U.S. space agency, 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 on Nov. 6, 1976. 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 (1.5 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

The National Aeronautics and Space Administration (NASA) is the U.S. government agency in charge of the civilian space program as well as aeronautics and aerospace research. Founded in 1958, NASA is a civilian space agency aimed at exploring the universe with space telescopes,  satellites, robotic spacecraft, astronauts and more. The space agency has 10 major centers based across the U.S. and launches robotic and crewed missions from the Kennedy Space Center in Cape Canaveral Florida. It's astronaut corps is based at the Johnson Space Center in Houston. To follow NASA's latest mission, follow the space agency on Twitter or any other social channel, of visit:
