1962-006A
The S-016 payload, also designated OSO A consisted of two sections: the `wheel' and a despun section called the `sail' which carried a solar array and some of the experiments. The wheel section had thrusters on booms to control the spin rate.
Orbiting Solar Observatory 1 was launched at 1606 on 1962 Mar 7. The launch vehicle was a Thor Delta. OSO 1 transmitted until 1963 Aug 3, although useful data stopped in May 1962; OSO 1 reentered on 1981 Oct 8.
