OGO 1

  1964-054A

---

OGO I was launched at 0123 on 1964 Sep 5 by Atlas Agena D from LC12 at Cape Kennedy. It was inserted into a 281 x 149385 km x 31.1 deg orbit. The two large booms failed to deploy and the attitude control system failed because an earth sensor was obscured. On Sep 10 a ground command signal oriented the solar panels to the sun and the experiments were operational, sending back data until 1969 Nov 25. The spacecraft was put on standby until 1971 Nov 1; it finally stopped transmitting around 1972 Feb 15. In 1999 Space Command issued a revised decay date of 1980 Aug 10, but in 2000 it resumed issuing orbital elements.
