Satellite edit
The satellite was box-shaped, measuring 1.66 by 2.1 by 1.77 metres; solar arrays spanned 15.9 metres tip to tip. The arrays, supplemented by nickel-hydrogen batteries during eclipse, provided 1800 watts of power. The payload housed 21 C-band and 4 Ku-band transponders. It could accommodate 15,000 two-way voice circuits and two TV channels simultaneously. It had a launch mass of 1928 kg.[2] The satellite was deactivated in January 1998.
Launch edit
The satellite was successfully launched into space on 15 December 1981 at 23:35:00 UTC, by means of an Atlas SLV-3D Centaur-D1AR vehicle from the Cape Canaveral Air Force Station, Florida, United States.
