NOAA / ESSA satellite seriesNASA and the newly-rechristened National Oceanic & Atmospheric Administration (formerly ESSA) launch NOAA-1, a weather satellite intended to operate in a near-polar low Earth orbit. Equipped with four cameras, NOAA-1 will operate in orbit for nearly a year before it begins suffering equipment malfunctions. Overheating in the spacecraft’s attitude control system forces ground controllers to turn off some of its weather sensing equipment, and NOAA-1 will eventually be shut down in August 1971.
