Intelsat III |
Intelsat III F-6 was a communications satellite owned by Intelsat. The satellite had an estimated useful life of 5 years.
The sixth of eight Intelsat III satellites to be launched, Intelsat III F-6 was built by TRW. It was a 293-kilogram (646 lb) spacecraft equipped with two transponders to be powered by body-mounted solar cells generating 183 watts of power. [3] It had a design life of five years and carried an SVM-2 apogee motor for propulsion. [4]
Intelsat III F-6 was launched on a Delta M rocket, flying from Launch Complex 17A at the Cape Canaveral Air Force Station. The launch took place on January 15, 1970, with the spacecraft bound for a geosynchronous transfer orbit. [1]
