It was part of a series of satellites called Advanced TIROS-N, being the fifth of the series.[5] NOAA-12 was launched on an Atlas E rocket on May 14, 1991 from Vandenberg Air Force Base, California. The satellite design provides an economical and stable sun-synchronous (morning equator-crossing) platform for advanced operational instruments to measure the earth's atmosphere, its surface and cloud cover, and the near-space environment.[5]The Satellite Operations Control Center is located in Suitland, Maryland. Major command stations for satellite control are located near Fairbanks, Alaska and on Wallops Island, Virginia; a backup station for connection when the satellite is unavailable from the main stations is located at Point Barrow, Alaska. The last contact occurred on August 10, 2007.[2] Instruments
