Nimbus 3

Status: Completed
Mission Category: Historical Missions
Launch Date: April 14, 1969
Launch Location: Vandenberg Air Force Base, CA

Nimbus 3, the third in a series of second-generation meteorological research-and-development satellites, was designed to serve as a stabilized, earth-oriented platform for the testing of advanced meteorological sensor systems and the collecting of meteorological data. The polar-orbiting spacecraft consisted of three major elements: (1) a sensory ring, (2) solar paddles, and (3) the control system housing. The solar paddles and the control system housing were connected to the sensory ring by a truss structure, giving the satellite the appearance of an ocean buoy.
