sts-41d

Discovery's primary cargo consisted of three commercial communications satellites: SBS-D for Satellite Business Systems, Telstar 3C for Telesat of Canada, and Syncom IV-2, or Leasat-2, a Hughes-built satellite leased to the US Navy. Leasat-2 was the first large communications satellite designed specifically to be deployed from the Space Shuttle. All three satellites were deployed successfully and became operational.

STS-41D

STS-41-D was the 12th flight of NASA's Space Shuttle program, and the first mission of the orbiter Discovery. It was launched from Kennedy Space Center, Florida, on 30 August 1984, and landed on 5 September. Three commercial communications satellites were deployed into orbit during the six-day mission, and a number of scientific experiments were conducted.
The mission was delayed by more than two months from its original planned launch date, having experienced the Space Shuttle program's first launch abort at T-6 seconds on 26 June 1984.

The Lion Brothers version of the STS-41D patch has the largest sailing ship.
