NASA Space Shuttle Discovery STS-51G Mission Patch Patch is approximately 4″ x 4.75″. Discovery lifted off from Launch Complex 39A, Kennedy Space Center (KSC), at 7:33 a.m. EDT on June 17, 1985. The mission’s crew members included Daniel C. Brandenstein, commander; John O. Creighton, pilot; Shannon W. Lucid, Steven R. Nagel, and John M. Fabian, mission specialists; and Patrick Baudry, from France, and Prince Sultan Sultan bin Salman Al Saud, from Saudi Arabia, both payload specialists. STS-51-G carried three communications satellites as its primary cargo. These were Arabsat-1B (Arab Satellite Communications Organization); Morelos-1 (Mexico); and Telstar-303 (AT&T Corporation); all three were Hughes-built satellites. All three successfully utilized Payload Assist Module (PAM-D) booster stages to achieve geostationary transfer orbits (GTO) after being deployed from Discovery. Also carried was the SPARTAN-1 (Shuttle Pointed Autonomous Research Tool for AstroNomy) a deployable/retrievable carrier module, designed to be deployed from the orbiter and fly free in space before being retrieved. SPARTAN-1 included 140 kg (310 lb) of astronomy experiments. It was deployed and operated successfully, independent of the orbiter, before being retrieved. Discovery furthermore carried an experimental materials-processing furnace, two French biomedical experiments (French Echocardiograph Experiment (FEE) and French Postural Experiment (FPE)),[3] and six Getaway Special (GAS) experiments, which were all successfully performed, although the GO34 Getaway Special shut down prematurely. This mission was also the first flight test of the OEX advanced autopilot which gave the orbiter capabilities above and beyond those of the baseline system. The mission’s final payload element was a High Precision Tracking Experiment (HPTE) for the Strategic Defense Initiative (SDI) (nicknamed “Star Wars”); the HPTE failed to deploy properly during its first try on the mission’s 37th orbit, because the orbiter was not at the correct attitude. It was successfully deployed on orbit 64. Discovery landed at Edwards Air Force Base at 9:11:52 a.m. EDT on June 24, 1985, after a mission duration of 7 days, 1 hour, 38 minutes, and 52 seconds.
