Flight

Launch from Cape Canaveral (KSC); landing on Edwards AFB.

Two earlier launch attempts, one on August 24, 1985 and another on August 25, 1985 were scrubbed, because of bad weather and a computer failure.

The crew deployed the communications satellites AUSSAT-1 (Australia) ASC-1 (USA) on flight day one and Syncom IV-4/Leasat-4 (US Navy) on flight day three.

EVAs by William Fisher and James van Hoften were performed on September 01, 1985 (7h 08m) and September 02, 1985 (4h 30m). They captured satellite Syncom IV-3/Leasat-3 in space, repaired it, and deployed the satellite again.

In addition, a middeck materials processing experiment was flown.
