Orbiting Astronomical Observatory

(OAO)
(series of 1960s-1970s NASA space telescopes)

The name Orbiting Astronomical Observatory (OAO) was used for four NASA space telescopes launched in the 1960s and 1970s. Two of them failed before observing, OAO-1 and OAO-B. OAO-2, named Stargazer, was operational 1969-1973, hosting a number of ultraviolet (UV) telescopes (one set of them named the Celescope) and was the first successful space telescope. OAO-3, named Copernicus, was operational from 1972-1981, hosting both UV and X-ray telescopes.
