ORFEUS


American ultraviolet astronomy satellite. One launch, 1996.11.19. ORFEUS was a German astronomical satellite. It was deployed by the shuttle remote manipulating system arm and retrieved after six days of free flight.

The main instrument was a 1 meter telescope with extreme ultraviolet (400-1150 Angstroms) and far ultraviolet (900-1250 Angstrom) spectrometers of high spectral resolution. Also carried was the Princeton Interstellar Medium Absorption Profile Spectrograph which studied the fine structure of ultraviolet absorption lines in stellar spectra caused by interstellar gas. The ORFEUS program was managed by the German space agency and the Shuttle Pallet Satellite (SPAS) spacecraft bus was made by Messerschmitt-Bolkow-Blohm.

AKA: Orbiting and Retrievable Far and Extreme UV Spectrometer.
First Launch: 1996.11.19.
Number: 1 .

Associated Launch Sites
  • Cape Canaveral America's largest launch center, used for all manned launches. Today only six of the 40 launch complexes built here remain in use. Located at or near Cape Canaveral are the Kennedy Space Center on Merritt Island, used by NASA for Saturn V and Space Shuttle launches; Patrick AFB on Cape Canaveral itself, operated the US Department of Defense and handling most other launches; the commercial Spaceport Florida; the air-launched launch vehicle and missile Drop Zone off Mayport, Florida, located at 29.00 N 79.00 W, and an offshore submarine-launched ballistic missile launch area. All of these take advantage of the extensive down-range tracking facilities that once extended from the Cape, through the Caribbean, South Atlantic, and to South Africa and the Indian Ocean. More...
  • Cape Canaveral LC39B Shuttle, Saturn V, Saturn I launch complex. LC39A and LC39B, part of the Kennedy Space Center, were built on Merritt Island (north/northwest of the Cape) to support the Saturn V/Apollo lunar landing program in 1963-1966. The sites were modified in the last half of the 1970s to support the manned Space Shuttle program. More...
