Orbiting geophysical observatory

In spite of early difficulties with the vehicle, nineteen of the twenty experiments aboard NASA's second orbiting geophysical observatory (OGO II) were reported functioning in early November. The satellite was launched on Oct. 14 from Vandenberg Air Force Base in California and moves in a very eccentric orbit inclined at 86° to the equator. OGO II is the second of a series of seven geophysical satellites to be put into a polar orbit. When the series is complete, four vehicles will be in eccentric orbits, and three will fly near the earth.
