TRAAC, 205
Orbit data source: Space-Track
TRAAC, 205 is a payload satellite owned by USN BuWeps (US) in LEO that was launched on Wed, 15 Nov 1961 UTC via a THOR ABLESTAR 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.
