1965-007A
The S-017 payload, OSO B, was damaged in an accident on 1964 Apr 14 when the Altair X-248A6 third stage ignited during a ground test and the vehicle launched itself to the building ceiling. Unlike the later X-258, the X-248 igniter was sensitive to electrostatic potentials generated by normal activity in the clean room. There were three fatalities.
Parts from OSO B were combined with an engineering prototype to create OSO B2, which was launched at 1636 on 1965 Feb 3 by a Delta C from Cape Canaveral. 12 minutes later, Orbiting Solar Observatory 2 was in a 96.40 min, 550 x 634 km x 32.9 deg orbit. It transmitted regularly until 1965 Nov and was used occasionally until mid 1966.
