One of Discovery's two satellite payloads on mission STS-51D, the Hughes Syncom-IV/Leasat 3 geosynchronous communications satellite, remained inert after deployment on April 13, 1985 and engineers quickly determined that a likely culprit was a faulty switch on the satellite's side.

STS 51-D was the fourth Discovery shuttle flight. On board were Karol Bobko, Donald Williams, Rhea Seddon, David Griggs, Jeffrey Hoffman, Charles Walker and US Senator Jake Garn. During this mission, the TELESAT-l (ANIK C-1) communications satellite was deployed, attached to Payload Assist Module (PAM-D) motor.

Senator aboard resented, and had one of the worst cases of space sickness ever recorded. AKA: Discovery. Launched: 1985-04-12. Returned: 1985-04-19. Number crew: 7 . Duration: 7.00 days.

STS-51 was a NASA Space Shuttle Discovery mission that launched the Advanced Communications Technology Satellite (ACTS) in September 1993. Discovery's 17th flight also featured the deployment and retrieval of the SPAS-ORFEUS satellite and its IMAX camera, which captured spectacular footage of Discovery in space.

2013年4月24日 · STS-51-D was the sixteenth flight of NASA's Space Shuttle program, and the fourth flight of Space Shuttle Discovery. [1] . The launch of STS-51-D from Kennedy Space Center (KSC), Florida, on 12 April 1985 was delayed by 55 minutes, after a boat strayed into the restricted Solid Rocket Booster (SRB) recovery zone.

Mission 51-D was originally set for a March launch and included deployment of the Hughes LEASAT 3 spacecraft and retrieval of NASA's Long Duration Exposure Facility. It was remanifested following the decision to cancel Mission 51-E, which was to have been flown by orbiter Challenger.
