The OSO-8 Satellite

artist concept of OSO-8 The 8th Orbiting Solar Observatory (OSO-8) was launched on 21 June 1975. While OSO-8's primary objective was to observe the Sun, four instruments were dedicated to observations of other celestial X-ray sources brighter than a few milliCrab. OSO-8 ceased operations on 1 October 1978.

Mission Characteristics

* Lifetime : 21 June 1975 - 1 October 1978
* Energy Range : 0.15 keV - 1 MeV
* Payload :
  • GSFC Cosmic X-Ray Spectroscopy Experiment (GCXSE)
    Detector A (2-60 keV): Eff. area = 263 cm2, FOV = 5°
    Detector B (2-20 keV): Eff. area = 37 cm2, FOV = 3°
    Detector C (2-60 keV): Eff. area = 237 cm2, FOV = 5°
  • High Energy Celestial X-ray Experiment
    0.01-1 MeV eff. area 27.5 cm2, FOV 5°
