GOES 1 (SMS-C), 8366

Orbit data source: Space-Track

GOES 1 (SMS-C), 8366 is a payload satellite owned by NOAA (US) in GEO that was launched on Thu, 16 Oct 1975 UTC via a DELTA 2914 launch vehicle from the Air Force Eastern Test Range (AFETR). Payload-class satellites include a variety of spacecraft equipped with specific instruments for various scientific and technological missions. These include communications satellites like Starlink; space stations such as the ISS; scientific satellites like the Hubble; Earth observation satellites from companies like Planet Labs, Umbra, and HawkEye 360; GPS; miniature CubeSats for education and research; and military/defense satellites.
