NOAA / ESSA satellite seriesNASA and the National Oceanic & Atmospheric Administration launch NOAA-2, a weather satellite intended to operate in a near-polar low Earth orbit. NOAA-2 is based on the already-flown ITOS satellite design, and will function in orbit through October 1974, with a break of only a few months due to a failed vertical temperature profile radiometer instrument. NOAA-2 will be shut down in January 1975.
