Associated space launch
OAO 2 (Orbiting Astronomical Observatory), also known as Stargazer, was one of a series of automated astronomical observatories that was ground controllable in orientation and was placed in a low-earth orbit.
OAO 2 was lifted into orbit during the mission ‘Atlas SLV-3C Centaur | OAO 2’, on board a Atlas SLV-3C Centaur space rocket.
The launch took place on Dec. 7, 1968, 8:40 a.m. from Launch Complex 36B.
