Satellite

The second of eight Intelsat III satellites to be launched, Intelsat III F-2 was built by TRW. It was a 293-kilogram (646 lb) spacecraft, with its mass reducing to 151 kilograms (333 lb) by entry into service as it burned propellant to reach its final orbit. The satellite carried an SVM-2 apogee motor for propulsion and was equipped with two transponders powered by body-mounted solar cells generating 183 watts of power.[3] It was designed for a five-year service life.[4]

Launch

The launch of Intelsat III F-2 made use of a Delta M rocket flying from Launch Complex 17A at the Cape Canaveral Air Force Station. The launch took place at 00:32:00 UTC on December 19, 1968, with the spacecraft entering a geosynchronous transfer orbit.[1] Intelsat III F-2 subsequently fired its apogee motor to achieve geostationary orbit. It was operated at a longitude of 24° west, over Brazil; however it ceased operations after only a year and a half in orbit, in mid-1971.[5]

Orbit

Intelsat III F-2 remains in orbit as a derelict satellite. As of February 7, 2014 it was in an orbit with a perigee of 38,438 kilometers (23,884 mi), an apogee of 39,317 kilometers (24,430 mi), inclination of 13.73 degrees and an orbital period of 26.60 hours.[2]
