The gantry-like MDD structure is used for servicing the shuttle orbiters in preparation for their ferry flight back to the Kennedy Space Center in Florida, including mounting the shuttle atop NASA's modified Boeing 747 Shuttle Carrier Aircraft. Space Shuttle Atlantis landed at 12:33 p.m. February 20, 2001, on the runway at Edwards Air Force Base, California, where NASA's Dryden Flight Research Center is located. The mission, which began February 7, logged 5.3 million miles as the shuttle orbited earth while delivering the Destiny science laboratory to the International Space Station. Inclement weather conditions in Florida prompted the decision to land Atlantis at Edwards. The last time a space shuttle landed at Edwards was Oct. 24, 2000.

Once servicing was complete, one of NASA's two 747 Shuttle Carrier Aircraft, No. 905, was readied to ferry Endeavour back to the Kennedy Space Center, FL.

Space Shuttle Discovery landed safely at NASA's Dryden Flight Research Center at Edwards Air Force Base in California at 5:11:22 a.m. PDT, August 9, 2005, following the very successful 14-day STS-114 return to flight mission. During their two weeks in space, Commander Eileen Collins and her six crewmates tested out new safety procedures and delivered supplies and equipment the International Space Station. Discovery spent two weeks in space, where the crew demonstrated new methods to inspect and repair the Shuttle in orbit. The crew also delivered supplies, outfitted and performed maintenance on the International Space Station. A number of these tasks were conducted during three spacewalks. In an unprecedented event, spacewalkers were called upon to remove protruding gap fillers from the heat shield on Discovery's underbelly. In other spacewalk activities, astronauts installed an external platform onto the Station's Quest Airlock and replaced one of the orbital outpost's Control Moment Gyroscopes. Inside the Station, the STS-114 crew conducted joint operations with the Expedition 11 crew. They unloaded fresh supplies from the Shuttle and the Raffaello Multi-Purpose Logistics Module. Before Discovery undocked, the crews filled Raffeallo with unneeded items and returned to Shuttle payload bay. Discovery launched on July 26 and spent almost 14 days on orbit.

KENNEDY SPACE CENTER, FLA. - News media photographers capture the approach of Space Shuttle Discovery, atop a modified Boeing 747 Shuttle Carrier Aircraft (SCA), as it is towed to the Mate_Demate Device (MDD) at the Kennedy Space Center (KSC) Shuttle Landing Facility (SLF). Discovery touched down on runway 15 at the SLF at about 10:00 a.m. EDT. The cross-country ferry flight became necessary when two days of unfavorable weather conditions at KSC forced Discovery to land on runway 22 at Edwards Air Force Base, Calif., on Aug. 9 following mission STS-114. On the return trip, stops were made at Altus Air Force Base, Okla., and Barksdale Air Force Base, La., where Discovery stayed for two nights. A crane on the MDD will lift Discovery from the SCA and place it on solid ground. Discovery will then be towed to the Orbiter Processing Facility where preparations will begin for its next flight, STS-121.

Following its landing on June 22, 2007, the Space Shuttle Atlantis is towed from the runway at Edwards Air Force Base to NASA Dryden's Mate-Demate Device (MDD) for post-flight processing in preparation for its return to the Kennedy Space Center in Florida.

KENNEDY SPACE CENTER, FLA. -- The crew members of mission STS-120 arrive at NASA's Kennedy Space Center Shuttle Landing Facility aboard T-38 jet aircraft to take part in terminal countdown demonstration test activities. Mission Specialist Paolo Nespoli, representing the European Space Agency on his first shuttle flight, is seen here with the space shuttle mate-demate device in the background. The terminal countdown demonstration test provides astronauts and ground crews an opportunity to participate in various simulated countdown activities, including equipment familiarization and emergency training. The STS-120 mission will deliver the U.S. Node 2 module, named Harmony, aboard space shuttle Discovery to the International Space Station. Launch of Discovery on mission STS-120 is targeted for Oct. 23 at 11:38 a.m. EDT on a 14-day mission to the International Space Station. Photo credit: NASA_Kim Shiflett

Beyond it runs Kennedy Parkway North, a route that passes the Vehicle Assembly Building seen in the upper right corner. At right is the tow-way, connecting the Orbiter Processing Facility with the SLF. Between it and the SLF parking area is the remote launch vehicle hangar, still under construction. On the horizon, looking east, is seen the Atlantic Ocean.

KENNEDY SPACE CENTER, FLA. - Discovery rests on its wheels under the mate_demate device on NASA Kennedy Space Center’s Shuttle Landing Facility. The equipment that lowered it to the ground is being removed. Discovery was returned to NASA Kennedy Space Center on a ferry flight from Edwards Air Force Base in California, arriving Aug. 21. Visible on Discovery is the tail cone that covers and protects the main engines during the ferry flight. Discovery will be towed to the Orbiter Processing Facility where the Multi-Purpose Logistics Module Raffaello still inside will be removed from the payload bay and transferred to the Space Station Processing Facility. The orbiter will then begin processing for the second Return to Flight mission, STS-121, scheduled for launch no earlier than March 2006.

An aerial view of the Shuttle Landing Facility shows the Mate/Demate device in the foreground, with two Shuttle Training Aircraft (STA) on the ground behind it. Visible in the background is the runway and the taxi way leading from the SLF to the right. The STAs are Grumman Gulfstream 2 aircraft with converted cockpits that emulate those in the Shuttles for practice landings at the SLF.

Robert 'Skip' Garrett; main propulsion advanced systems technician, and Chris Jacobs; main propulsion systems engineering technician, inspect external tank attachment fittings on the Space Shuttle Discovery as part of it's post-flight processing at NASA's Dryden Flight Research Center. The Space Shuttles receive post-flight servicing in the Mate-Demate Device (MDD) following landings at NASA's Dryden Flight Research Center, Edwards, California. The gantry-like MDD structure is used for servicing the shuttle orbiters in preparation for their ferry flight back to the Kennedy Space Center in Florida, including mounting the shuttle atop NASA's modified Boeing 747 Shuttle Carrier Aircraft. Space Shuttle Discovery landed safely at NASA's Dryden Flight Research Center at Edwards Air Force Base in California at 5:11:22 a.m. PDT, August 9, 2005, following the very successful 14-day STS-114 return to flight mission. During their two weeks in space, Commander Eileen Collins and her six crewmates tested out new safety procedures and delivered supplies and equipment the International Space Station. Discovery spent two weeks in space, where the crew demonstrated new methods to inspect and repair the Shuttle in orbit. The crew also delivered supplies, outfitted and performed maintenance on the International Space Station. A number of these tasks were conducted during three spacewalks. In an unprecedented event, spacewalkers were called upon to remove protruding gap fillers from the heat shield on Discovery's underbelly. In other spacewalk activities, astronauts installed an external platform onto the Station's Quest Airlock and replaced one of the orbital outpost's Control Moment Gyroscopes. Inside the Station, the STS-114 crew conducted joint operations with the Expedition 11 crew. They unloaded fresh supplies from the Shuttle and the Raffaello Multi-Purpose Logistics Module.
