The launch of the ferry was originally scheduled for 25 June 1984. However, the launch at T- 9 minutes was canceled because the backup systems failed. The next attempt on 26 June 1984, even aborted only at T-6 seconds. It was discovered in the third main engine an anomaly. Back in the Orbiter Processing Facility, the shuttle got a new engine. Furthermore, it was taken the charge of the mission STS -41 -F on board and the flight STS -41 -F has been completely deleted. A software error then also prevented the third launch attempt on 29 August 1984, and even the final launch was again delayed by 6 minutes and 50 seconds, as an aircraft invaded the skies of Cape Canaveral.
During the flight, three satellites were exposed Satellite Business System SBS -D, SYNCOM IV-2 (also known as LEASAT2 ) and TELSTAR.
The IMAX camera from the last mission also flew again.
With Charles Walker, the first U.S. astronaut industry was on board. Walker was not a NASA astronaut, he came from the U.S. aviation and aerospace company McDonnell Douglas.
