1966-049A
OGO B was the second elliptical orbit OGO and became Orbiting Geophysical Observatory 3 after launch. The satellite was orbited on 1966 Jun 7 by an Atlas Agena B from Cape Kennedy. It entered a 319 x 122173 km x 31.4 deg orbit. 3-axis attitude control was lost on Jul 23 but the instruments functioned well. Pitch oscillations near perigee overloaded the system. On 1969 Dec 1 operation was reduced to only the magnetic survey instrument. OGO 3 was finally switched off on 1972 Feb 29.
