ERS 6, 608
Orbit data source: Space-Track
ERS 6, 608 is a payload satellite owned by USAF SSD (US) in LEO that was launched on Thu, 09 May 1963 UTC via an ATLAS AGENA B launch vehicle from the Air Force Western Test Range (AFWTR). 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.
