The 41-D crew successfully completed three satellite placements, of which this was the last. Telstar was the second 41-D deployed satellite to be equipped with a payload assist module (PAM-D). The frame was exposed with a 70mm camera.

41D-37-050 (1 Sept 1984) --- Telstar, the third of three satellites to be placed into space via the Earth-orbiting Discovery, departs from the cargo bay of the manned vehicle during 41-D's third day in space. The scene was photographed at 9:35 a.m. (CDT), Sept. 1, 1984, with a 70mm handheld hasselblad camera aimed through the windows on the flight deck. Heavy clouds cover much of the water and land mass of Earth in the background.

41D-36-034 (30 Aug 1984) --- Less than nine hours after the first launch of the Discovery, its astronaut crewmembers photographed deployment of the SBS-4 communications satellite. The cylindrical spacecraft spins and rises from its cradle-like protective shield to begin life in space. A number of maneuvers will place it in its desired orbit. A 70mm camera, aimed through the spacecraft’s aft flight deck windows, was used to expose the frame.

41D-06-013 (6 Sept 1984) --- Payload specialist Charles Walker works with the continuous flow electrophoresis systems (CFES) experiment, located in the middeck.

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.

STS041-S-002 (7 May 1990) --- These five astronauts have been assigned to fly the STS-41 mission for the National Aeronautics and Space Administration (NASA).

Hawley participate in and underwater simulation of a 41-D contingency extravehicular activity (EVA) in the Johnson Space Center's weightless environment training facility (WET-F). All Shuttle crews, many of which are not scheduled for definite EVAs, possess team members trained to perform in space certain tasks normally done remotely in the event of systems failures. Among those contingent tasks is the manual closing of the payload bay doors. Mullane and Hawley are two of three mission specialists assigned duty on the seven-day 41-D flight. This photograph was taken by Otis Imboden.

S84-35757 (May 1984) --- Astronaut Judith A. Resnik, 41-D mission specialist, and Charles Walker, payload specialist for that June 1984 flight, prepare for some scheduled intravehicular activity involving the continuous flow electrophoresis systems (CFES) experiment. CFES will join the six-member crew aboard the Earth-orbiting Discovery for a seven day mission. The two share in preparing a sample to be processed by the CFES. In the background are stowage lockers and a CFES trainer-- part of the Shuttle one-g trainer at NASA's Johnson Space Center (JSC). Walker, an engineer at McDonnell Douglas Astronautics Co. in St. Louis, Missouri, will be the first Shuttle payload specialist to represent a project designed for commercial purposes. As payload specialist, his job will be to run the materials electrophoresis-operations-in-space project.

KENNEDY SPACE CENTER, FLA. -- Technicians work in the aft compartment of Shuttle Endeavour's payload bay, where a new Enhanced Main Events Controller (E-MEC) will be installed. The original E-MEC in Endeavour became suspect during the Jan. 31 launch countdown and mission STS-99 was delayed when NASA managers decided to replace it. Each Shuttle carries two enhanced master events controllers (E-MECs), which provide relays for onboard flight computers to send signals to arm and fire pyrotechnics that separate the solid rockets and external tank during assent. Both E-MECs are needed for the Shuttle to be cleared for flight. Currently Endeavour and Columbia are the only two orbiters with the E-MECs. Built by Rockwell's Satellite Space Electronics Division, Anaheim, Calif., each unit weighs 65 pounds and is approximately 20 inches long, 13 inches wide and 8 inches tall. Previously, three Shuttle flights have been scrubbed or delayed due to faulty MECs: STS-73, STS-49 and STS-41-D. Before workers can begin E-MEC replacement efforts at the launch pad, cryogenic reactants had to be offloaded from the orbiter and Space Shuttle ordnance disconnected. The next scheduled date for launch of STS-99 is Feb. 11 at 12:30 p.m. EST
