First flight of space shuttle Discovery; deployed SBS 4, Leasat 1, Telstar 3C. First launch attempt aborted at T-3 seconds after SSMEs ignited. Toilet failed during mission. First occurrence of blow-by in SRB field joints.

AKA: Discovery. Launched: 1984-08-30. Returned: 1984-09-05. Number crew: 6 . Duration: 6.04 days.

Payloads: Satellite Business System (SBS)-D communications satellite with Payload Assist Module (PAM)-D deployment, Syncom IV-2 communications satellite with its unique stage deployment, Telstar (American Telephone and Telegraph) 3-C with PAM-D deployment, Office of Aeronautics and Space Technology (OAST)-1 experiments. Deployment and restowing of large solar array. Continuous Flow Electrophoresis (CFES). IMAX camera.

Orbits of Earth: 96. Distance traveled: 4,007,266 km. Orbiter Liftoff Mass: 119,511 kg. Orbiter Mass at Landing: 91,476 kg. Payload to Orbit: 21,552 kg. Payload Returned: 5,123 kg. Landed at: Runway 17 dry lake bed at Edwards Air Force Base, . Landing Speed: 370 kph. Touchdown miss distance: 765 m. Landing Rollout: 3,131 m. A student experiment, sponsored by Rockwell International, of indium crystal growth using the float zone technique was successful, although a blown fuse resulted in a premature shutdown.

Mission Objectives:

Launch:
August 30, 1984, 8:41:50 a.m, EDT. Launch attempt June 25 scrubbed during T-9 minute hold due to failure of orbiter's back-up general purpose computer (GPC). Launch attempt June 26 aborted at T-4 seconds when GPC detected anomaly in orbiter's number three main engine. Discovery returned to OPF and number three main engine replaced. (To preserve launch schedule of future missions, 41-D cargo remanifested to include payload elements from both 41-D and 41-F flights; 41-F mission cancelled.) Shuttle restacked and returned to pad. Third launch attempt Aug. 29 delayed when discrepancy noted in flight software of Discovery's master events controller relating to solid rocket booster fire commands. A software patch was verified and implemented to assure all three booster fire commands were issued in the proper time interval. Launch Aug. 30 delayed six minutes, 50 seconds when private aircraft intruded into warning area off coast of Cape Canaveral. Launch Weight: 263,477 lbs.
Orbit:
Altitude: 184nm
Inclination: 28.5 degrees
Orbits: 97
Duration: Six days, zero hours, 56 minutes, four seconds.
Distance: 2,490,000 miles

Hardware:
SRB: BI-011
SRM: 013LW(HPM)
ET : 13/LWT-6
MLP : 2
SSME-1: SN-2109
SSME-2: SN-2018
SSME-3: SN-2021

Landing:
September 5, 1984, 8:37:54 s.m. PDT, Runway 17, Edwards Air Force Base, Calif. Rollout distance: 10,275 feet. Rollout time:60 seconds. Landing planned for Edwards desert runway because it was Discovery's first flight. Orbiter returned to KSC Sept. 10, 1984. Landing Weight: 201,674 lbs.

Mission Highlights:
Three satellites deployed: Satellite Business System SBS-D, SYNCOM IV-2 (also known as LEASAT2) and TELSTAR. The 102- foot-tall, 13-loot-wide Office of Application and Space Technology (OAST-1) solar wing extended from payload bay. Wing carried different types of solar cells and extended to full height several times. It demonstrated large lightweight solar arrays for future in building large facilities in space such as Space Station. Other payloads: Continuous Flow Electrophoresis System (CFES) Ill; Radiation Monitoring Equipment (RME); Shuttle Student Involvement Program (SSIP) experiment; lMAX camera, being flown second time; and an Air Force experiment, Cloud Logic to Optimize Use of Defense Systems (CLOUDS).
