RADIATION SAT (5E 1), 671
Orbit data source: Space-Track
RADIATION SAT (5E 1), 671 is a payload satellite owned by USN BuWeps (US) in LEO that was launched on Sat, 28 Sep 1963 UTC via a THOR ABLESTAR 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.
