Orbiting Geophysical Observatory (OGO) Program [1] of NASA refers to the six satellites launched by the United States that were in use from September 1964 to 1972, designed to study the Earth's magnetosphere.[2] The satellites successfully studied the interactions between the Earth and the Sun, despite a number of technical problems. Each satellite had 20 to 25 instruments. The project manager for all 6 OGO projects was Wilfred Scull.
