Deployed from STS 41B 4 February 1984; failed to reach proper orbit; recovered by STS-51A. The Westar series of geostationary spacecraft provide commercial communications services for Western Union. Westar 6 failed to achieve geosynchronous orbit after being deployed from the Space Shuttle. It was later retrieved by another Shuttle mission (November 14, 1984) and returned for refurbishment and relaunch. All Westars have been launched by NASA on a reimbursable basis. Spacecraft: Westar uses the Hughes HS-376 spacecraft design. Spin stabilised with a despun antenna section. Body mounted solar cells. Once on orbit, an outer cylinder deploys downward in 'dixie-cup' fashion to increase the solar panel area. Payload: Westar spacecraft typically carried 12 to 24 transponders in the 4-6 GHz range. A single antenna reflector (72 inch diameter) is used with an array of offset feed horns. The reflector uses two polarisation-selective surfaces for horizontal and vertical polarised signals.
