S86-41700 (19 May 1984) --- The Space Shuttle Discovery moves towards Pad A on the crawler transporter for its maiden flight. Discovery will be launched on its first mission no earlier than June 19, 1984. Flight 41-D will carry a crew of six; Commander Henry Hartsfield, Pilot Mike Coats, Mission Specialists Dr. Judith Resnik, Dr. Steven Hawley and Richard Mullane and Payload Specialist Charles Walker. Walker is the first payload specialist to fly aboard a space shuttle. He will be running the materials processing device developed by McDonnell Douglas as part of its Electrophoresis Operations in Space project. Mission 41-D is scheduled to be a seven-day flight and to land at Edwards Air Force Base in California. The Syncom IV-1 (LEASAT) will be deployed from Discovery's cargo bay and the OAST-1, Large Format Camera, IMAX and Cinema 360 cameras will be aboard.

CAPE CANAVERAL, Fla. -- At the Kennedy Space Center in Florida, the payloads for the STS-41D space shuttle flight are shown loaded in Discovery’s cargo bay. With the orbiter in the vertical position at Launch Pad 39A, the payloads are, from top to bottom, OAST-1 a 102-foot-tall, 13-foot-wide Office of Application and Space Technology solar panel), the Satellite Business System SBS-D , Telstar 3-C, and Syncom IV-2. The six day mission is scheduled for launch on Aug. 29, 1984. The six crew members are Commander Henry W. Hartsfield Jr., Pilot Michael L. Coats, Mission Specialists Judith A. Resnik, Steven A.
