Summary
STS-41-D launched on a Lockheed Space Operations Company Space Shuttle from Launch Complex 39A, Kennedy Space Center, FL, USA on August 30, 1984. It was Lockheed Space Operations Company's 3rd launch, 3rd this year and humanity's 2,868th orbital launch attempt. It was the 12th Space Shuttle flight and the 3rd this year. The payload was bound for low Earth orbit (LEO). Discovery (STS 41-D), one of 7 catalogued objects, reached a 303 × 309 km orbit inclined 28.5°. 6 crew members flew: Henry 'Hank' Hartsfield, Steven Hawley, Michael Coats, Mike Mullane, Judith Resnik and Charles D. Walker. The spacecraft was Space Shuttle Discovery (OV-103). 7 objects from this launch are catalogued, 4 of them payloads.

Spacecraft
Space Shuttle Discovery (OV-103)
Space Shuttle Discovery (Orbiter Vehicle Designation: OV-103) is one of the orbiters from NASA's Space Shuttle program and the third of five fully operational orbiters to be built. Its first mission, STS-41-D, flew from August 30 to September 5, 1984. Over 27 years of service it launched and landed 39 times, gathering more spaceflights than any other spacecraft to date. Discovery became the third operational orbiter to enter service, preceded by Columbia and Challenger. It embarked on its last mission, STS-133, on February 24, 2011 and touched down for the final time at Kennedy Space Center on March 9, having spent a cumulative total of almost a full year in space. Discovery performed both research and International Space Station (ISS) assembly missions. It also carried the Hubble Space Telescope into orbit. Discovery was the first operational shuttle to be retired, followed by Endeavour and then Atlantis.
- Destination: Low Earth Orbit
- Mission length: 6 days
Space Shuttle Discovery successfully landed at Edwards Air Force Base after this mission.
