Its mass is 734 kilograms. Its perigee to Earth is 829 kilometers. Its apogee is 845 kilometers away from Earth. Its inclination is 98.70°. It was managed by the U.S. National Oceanic and Atmospheric Administration (NOAA); designed and launched by NASA. The spacecraft was 3-axis stabilized. TIROS-N was operated for 868 days until deactivated by NOAA on 27 February 1981.{{cite web|url=http://science1.nasa.gov/missions/tiros/|title=TIROS-N/NOAA Program - 1978-1986|publisher=NASA|access-date=May 10, 2014|url-status=dead|archiveurl=https://web.archive.org/web/20141209032810/http://science1.nasa.gov/missions/tiros/|archive-date=December 9, 2014 }} {{PD-notice}}
