Orbiting Solar Observatory

Astronomy

A series of NASA satellites, which studied ultraviolet, X-ray, and gamma-ray emission from the Sun during an entire solar cycle. Eight were launched between 1962 and 1975. Among their discoveries were the first observations of gamma rays from solar flares, and bursts of hard X-rays and ultraviolet emission at the impulsive stage of flares.

Space Exploration

Any of eight nearly identical solar observatories launched by NASA from 1962 to 1975. OSOs are designed mainly to point several ultraviolet and X-ray telescopes at the Sun from a platform mounted on a cylindrical wheel. OSO 1, active from its launch in March 1962 to August 1963, was a 200-kg spacecraft deployed to measure solar electromagnetic radiation in the ultraviolet, X-ray, and gamma-ray wavelengths, and to investigate dust particles in space. The University of Minnesota gamma-ray experiment aboard measured the intensity and direction of low-energy gamma rays in space.
OSO 5 had the longest lifespan, from January 1969 to July 1975. It studied solar X-ray bursts and measured the diffuse cosmic background. OSO 8, launched in June 1975 and active until October 1978, had four additional instruments to study other celestial X-ray sources.
