40 Years Ago: Space Shuttle Discovery Makes its Public Debut
On Oct. 16, 1983, NASA’s newest space shuttle, Discovery, made its public debut during a rollout ceremony at its manufacturing plant in Palmdale, California. Under construction for three years, Discovery joined NASA’s other two space-worthy orbiters, Columbia and Challenger, and atmospheric test vehicle Enterprise. The rollout ceremony, attended by NASA and other officials, also featured the astronauts assigned to Discovery’s first mission, STS-41D, then planned for launch in June 1984. By the time NASA retired Discovery in 2011, it had flown 39 missions, more than any other orbiter, in a career spanning 26 years and flying every type of mission envisioned for the space shuttle. The Smithsonian Institution’s National Air and Space Museum has Discovery on display at its Stephen F. Udvar-Hazy Center in Chantilly, Virginia.

On Jan. 25, 1979, NASA announced the names of the first four space-worthy orbiters – Columbia, Challenger, Discovery, and Atlantis. Like the other vehicles, NASA named Discovery after historical vessels of exploration – Captain James Cook’s HMS Discovery used during his third and final voyage (1776-1779) and Henry Hudson’s Discovery used during his 1610-1611 search for the Northwest Passage. On Jan. 29, NASA signed the contract with Rockwell International of Downey, California, to build and deliver Discovery. Construction began in June 1980 and finished in February 1983. The newest orbiter included several upgrades from the two earlier vehicles, and through more extensive use of blankets instead of tiles in the thermal protection system, weighed 6,870 pounds less than Columbia. After completion of systems testing, workers prepared Discovery for its first public appearance.

The rollout ceremony for Discovery took place on Oct. 16, 1983, at Rockwell International’s Palmdale facility, attended by hundreds of employees and visitors. In addition to NASA and other dignitaries, five of the six the astronauts assigned to Discovery’s first mission also participated, thanking the assembled employees for their hard work in building their spacecraft. They included STS-41D Commander Henry W. “Hank” Hartsfield, Pilot Michael L. Coats, and Mission Specialists Richard M. “Mike” Mullane, Steven A. Hawley, and Judith A. Resnik. Payload Specialist Charles D. Walker could not attend.

Following the ceremony, workers trucked Discovery 36 miles overland to NASA’s Dryden, now Armstrong, Flight Research Center at Edwards Air Force Base (AFB) in California’s Mojave Desert, the trip taking about 10 hours. In the Mate-Demate Device (MMD), workers placed Discovery atop the Shuttle Carrier Aircraft (SCA), a modified Boeing 747, to begin the ferry flight. The first leg of the journey started on Nov. 6 with a stop at Vandenberg AFB on the California coast, where workers used Discovery and the SCA to test the Orbiter Lifting Fixture, a scaled down version of the MDD planned for use exclusively at Vandenberg. At the time, NASA and the Department of Defense planned to fly space shuttles, with Discovery as the designated orbiter, from Vandenberg’s Space Launch Complex-6 on military polar orbital missions, beginning with STS-62A in 1986. The agencies mothballed those plans following the Challenger accident. From Vandenberg, on Nov. 8 the SCA carried Discovery to Carswell AFB near Ft. Worth for an overnight refueling stop, before continuing to NASA’s Kennedy Space Center in Florida on Nov. 9. The following day, workers towed Discovery to the Orbiter Processing Facility (OPF) for initial receiving inspections. After a move to the nearby Vehicle Assembly Building (VAB) on Dec. 9 for temporary storage, workers returned Discovery to the OPF on Jan. 10, 1984, to begin processing it for its first flight.

Four months later, on May 12, workers towed Discovery from the OPF to the VAB and mated it to an External Tank and twin Solid Rocket Boosters. The entire stack rolled out to Launch Pad 39A on May 19 in preparation for the planned June 25 launch of the STS-41D mission. As with any new orbiter, on June 2 NASA conducted a 20-second Flight Readiness Firing of Discovery’s three main engines. On June 14, the six-person crew participated in a countdown demonstration test. They boarded Discovery on June 25 for a launch attempt that aborted at the T minus nine-minute mark due to a failure of Discovery’s back-up General Purpose Computer. Technicians replaced the failed unit with one from Challenger for another launch attempt the next day. This time Discovery’s onboard computer aborted the launch four seconds before liftoff but after two of the three main engines had already ignited, resulting in some anxious moments in the crew compartment. To ease the tension, Hawley is reported to have said something along the lines of, “Gee, I thought we’d be a little higher when the engines shut off.” To make matters worse, a hydrogen fire at the base of the launch pad activated the fire suppression system, forcing the crew to evacuate the spacecraft under a deluge of water. The problem with the center engine required a replacement that engineers completed at the pad between July 3 and 5. But the delay caused NASA managers to shuffle payloads and launch schedules, and that required Discovery’s return to the VAB on July 14. Workers destacked the orbiter to return it to the OPF for the payload changes. That completed, and after restacking in the VAB, Discovery returned to Launch Pad 39A on Aug. 9 for a launch attempt 20 days later. A hardware problem resulted in a one-day delay, and finally on Aug. 30 Discovery lifted off on its first mission to space.

In the course of its 39 missions spanning more than 26 years, Discovery flew virtually every type of mission envisioned for the space shuttle, including government and commercial satellite deployments and retrievals, launching and servicing scientific observatories such as the Hubble Space Telescope, resupplying the Russian Mir space station, and assembling and maintaining the International Space Station. Discovery also flew the return to flight missions after both the Challenger and Columbia accidents. Discovery flew its final mission, STS-133, in February 2011. The following year, the Smithsonian Institution’s National Air and Space Museum placed space shuttle Discovery on display at its Stephen F. Udvar-Hazy Center in Chantilly, Virginia.
