Full Description This is the STS-37 Crew portrait. Pictured from left to right are Kenneth D. (Ken) Cameron, pilot, Jay Apt, mission specialist, Steven R. Nagel, commander, and Jerry L. Ross and Linda M. Godwin, mission specialists. Launched aboard the Space Shuttle Atlantis on April 5, 1991 at 9:22:44am (EST), the crew?s major objective was the deployment of the Gamma Ray Observatory (GRO). Included in the observatory were the Burst and Transient Source Experiment (BATSE), the Imaging Compton Telescope (COMPTEL), the Energetic Gamma Ray Experiment Telescope (EGRET), and the Oriented Scintillation Spectrometer Telescope (OSSEE).

Title The Compton Gamma Ray Observatory
Explanation The Compton Gamma Ray Observatory [ http://cossc.gsfc.nasa.gov/cossc/descriptions/cgro.html ] (CGRO) was the most massive instrument ever launched by a NASA Space Shuttle [ http://spaceflight.nasa.gov/shuttle/index.html ] in 1991 and continues to revolutionize gamma-ray astronomy [ http://cossc.gsfc.nasa.gov/gamma/gamma.html ]. Before Compton loses more stabilizing gyroscopes, NASA is considering [ http://cnn.com/2000/TECH/space/01/14/satellite.deorbit/index.html ] firing onboard rockets to bring it on a controlled reentry into the ocean. This orbiting observatory sees the sky in gamma-ray photons [ http://cossc.gsfc.nasa.gov/cossc/descriptions/espec1.html ] - light so blue humans can't see it. These photons are blocked by the Earth's atmosphere from reaching the Earth's surface. Results from CGRO, pictured above [ http://images.jsc.nasa.gov/images/pao/STS37/10064038.htm ], have shown the entire universe to be a violent and rapidly changing place - when viewed in gamma-rays. Astronomers using CGRO data continue to make monumental discoveries [ http://adsabs.harvard.edu/cgi-bin/nph-abs_connect?&text=CGRO&query_type=PAPERS ], including identifying mysterious gamma-ray bursts [ http://antwrp.gsfc.nasa.gov/cgi-bin/cossc/apod_search?gamma+ray+burst ] that uniquely illuminate the early universe, discovery of a whole new class of QSOs [ http://cossc.gsfc.nasa.gov/cossc/descriptions/egret_blazars.html ], and discovery of objects so strange [ http://cossc.gsfc.nasa.gov/cossc/descriptions/egret_src.html ] that astronomers can't yet figure out what they are.

Title Gamma Ray Observatory (GRO) in ground support structure at TRW
Description The Gamma Ray Observatory (GRO) is positioned in a support structure in TRW's assembly room for checkout and processing prior to shipment to the Kennedy Space Center (KSC). GRO is the heaviest NASA science satellite ever to be deployed by the Space Shuttle into low Earth orbit. GRO's trunnions are locked into the support structure. From left to right are three of the four GRO instruments including the Oriented Scintillation Spectrometer Experiment (OSSE), the Imaging Compton Telescope (COMPTEL), and the Energetic Gamma Ray Experiment Telescope (EGRET). The Burst and Transient Source Experiment (BATSE) equipment is located on GRO's corners. GRO, which weighs just over 35,000 pounds (15,876 kilograms), is a space-based observatory scheduled to be put into space by Atlantis, Orbiter Vehicle (OV) 104, next year. GRO is designed to study the universe in an invisible, high-energy form of light known as gamma rays. Gamma rays, which cannot penetrate the Earth's atmosphere, are of interest to

Title TRW processing and check out of Gamma Ray Observatory (GRO)
Description As they prepare for the shipment of the Gamma Ray Observatory (GRO) from TRW's assembly room to the Kennedy Space Center (KSC), TRW workers and NASA engineers are dwarfed by the heaviest NASA science satellite ever to be deployed by the Space Shuttle into low Earth orbit. GRO is suspended by overhead crane at one end and positioned in rack at the other end. The four GRO instruments include the Oriented Scintillation Spectrometer Experiment (OSSE) (at bottom), the Imaging Compton Telescope (COMPTEL) (center), the Energetic Gamma Ray Experiment Telescope (EGRET) (at top), and the Burst and Transient Source Experiment (BATSE) (located on GRO's corners).
