1984-011B / 1990-030A
The Westar 6 satellite was carried into orbit on the Space Shuttle Challenger in Feb 1984. Deployment from the cargo bay was normal, but when the PAM-D upper stage ignited the nozzle failed and the satellite was left in a low elliptical orbit. It was recovered by the 51-A mission. The underwriters, Merritt Syndicates, sold the satellite to Asiasat. Asiasat (the Asia Satellite Telecommunications Co. of Hong Kong) is a consortium of Cable & Wireless, Hutchinson Wampoa and the China International Trust and Investment Corp. (CITIC). Asiasat got Hughes to refurbish the satellite; it was then relaunched from China aboard a CZ-3 rocket, this time reaching GEO successfully. It was used for regional SE Asian communications.
