STS 41-D

This was the first flight of Discovery. Discovery launched from Kennedy Space Center on August 30, 1984 at 8:41 AM EDT and landed at Edwards Air Force Base on September 5 at 6:37 AM PDT. The shuttle orbited 97 times at an altitude of 184 nautical miles at an inclination of 28.5 degrees and travelled 2.5 million miles. The mission lasted 6 days, 0 hours, 56 minutes, and 4 seconds.

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

Discovery was crewed by Commander Henry W. Hartsfield, Pilot Michael J Coats, Mission Specialists Judith A. Resnick, Stephen A. Hawley, Richard M. Mullane, and Payload Specialist Charles D. Walker.
