![]() It is believed that the crew deployed the two DCSC-III satellites atop the IUS on the first day in space. In keeping with an agreement between NASA and the DOD, media coverage of the mission stopped at that point. 3, 1985, Atlantis roared off its launch pad on a pillar of flame and within eight minutes was in orbit around the Earth.

Space shuttle Enterprise arrived at KSC via SCA on Sept. ![]() Four days later, the five-member crew successfully completed the Terminal Countdown Demonstration Test, a final dress rehearsal of the countdown right up to the moment of engine ignition. Pailes.Īs required before the first launch of an orbiter, engineers successfully completed the Flight Readiness Firing, an 18-second test of Atlantis’ main engines on Sept. Left: STS-51J crew patch.Right: STS-51J crew photo – Robert L. In 1998, the DOD declassified the primary payloads, identifying them as a pair of third-generation Defense Space Communications Satellites (DSCS-III) and releasing photographs of their deployment from the shuttle’s payload bay atop an Inertial Upper Stage (IUS). The flight was a classified DOD mission, so few details on the crew’s on-orbit activities are known. Grabe, Hilmers, and Pailes were making their first flight, while Stewart tested the Manned Maneuvering Unit during his first mission, STS-41B. Pailes, a Department of Defense (DOD) Manned Spaceflight Engineer. “Bo” Bobko, a veteran of STS-6 (the first flight of space shuttle Challenger) and STS-51D, Pilot Ronald J.

Left: Space Shuttle Atlantis rolls out of Rockwell International’s Palmdale, California, facility. After ground processing, workers mated Atlantis to its External Tank and Solid Rocket Boosters in the Vehicle Assembly Building (VAB) and rolled it out to Launch Pad 39A on Aug. Atlantis rolled out of Rockwell International’s plant in Palmdale, California, on March 6, 1985, and arrived at NASA’s Kennedy Space Center (KSC) on April 12 after a cross-country ferry flight from Edwards Air Force Base (AFB) in California atop a Shuttle Carrier Aircraft (SCA), a modified Boeing 747. ![]() In its construction and use of advanced technologies, Atlantis was very similar to its sister ship Discovery that joined the fleet a year earlier. Space shuttle Atlantis, named after the two-masted research vessel used by the Woods Hole Oceanographic Institution between 19, was the fourth space-qualified orbiter to join the fleet. ![]()
