OGO-1 and OGO-3 MIT plasma experiments S4903

Abstract

Plasma proton and plasma electron prototype and flight models were designed, fabricated, and tested. Ground support equipment for the models was also prepared. The flight models were launched aboard the first and third Orbiting Geophysical Observatories on 4 Sept. 1964 and 6 June 1966. These experiments have generally functioned in accordance with the design specifications and useful data are still being received.
