The Shuttle Landing Facility (SLF), also known as Launch and Landing Facility (LLF) (IATA: QQS, ICAO: KTTS, FAA LID: TTS), is an airport located on Merritt Island in Brevard County, Florida, United States. It is a part of the Kennedy Space Center and was used by Space Shuttle for landing until July 2011. It was also used for takeoffs and landings for NASA training jets such as the Shuttle Carrier Aircraft and for civilian aircraft. Starting in 2015, Space Florida manages and operates the facility under a 30-year lease from NASA. In addition to ongoing use by NASA, private companies have been utilizing the SLF since the 2011 end of the Space Shuttle program.
== Facilities == The Shuttle Landing Facility covers 500 acres (2 km2) and has a single runway, 15/33. It is one of the longest runways in the world, at 15,000 feet (4,572 m), and is 300 feet (91 m) wide. Despite its length, astronaut Jack R. Lousma stated that he would have preferred the runway to be "half as wide and twice as long". Additionally, the SLF has 1,001 feet (305 m) of paved overruns at each end. The Mate-Demate Device (MDD), for use when the Shuttle was transported by the Shuttle Carrier Aircraft, was located just off the southern end of the runway. The runway is designated runway 15, or 33, depending on the direction of use. The runway surface consists of an extremely high-friction concrete strip designed to maximize the braking ability of the Space Shuttle at its high landing speed, with a paving thickness of 16.0 inches (40.6 cm) at the center. It uses a grooved design to provide drainage and further increase the coefficient of friction. The original groove design was found to actually provide too much friction for the rubber used in the Shuttle's tires, causing failures during several landings. This issue was resolved by grinding down the pavement, reducing the depth of the grooves significantly. The first air traffic control tower for the SLF was built on top of the 100-foot-tall (30 m) MDD. This was replaced by a 1952-vintage portable 30-foot-tall (9.1 m) military field tower located near the center of the runway on the east bank. In September 2003, it was replaced by a 82-foot-tall (25 m) permanent tower, with a co-located weather observation station. A local nickname for the runway is the "gator tanning facility", as some of the 4,000 alligators living at Kennedy Space Center regularly bask in the sunlight on the runway. The landing facility is managed by contractor EG&G, which provides air traffic control services, as well as managing potential hazards to landing aircraft, such as bird life. The Bird Team kept the facility clear of both local and migratory birds during Shuttle landings using pyrotechnics, blank rounds fired from shotguns and a series of 25 propane cannons arranged around the facility.
== History and usage ==
=== Space Shuttle era === On April 14, 1972, NASA announced the selection of KSC as the launch and landing site for the Space Shuttle program. On December 10, 1973, KSC requested bids from 50 construction firms to build a 15,000-foot (4,572 m) runway to accommodate the Shuttle. On March 18, 1974, NASA awarded a US$21,812,737 (equivalent to $142,400,965 in 2025) contract to Morrison–Knudsen for the construction of the runway, including overruns, aprons, taxiways, and access roads. Construction of the runway began on April 1, 1974. The SLF officially opened in 1976 after receiving certification from the Federal Aviation Administration. Columbia was the first Shuttle to arrive at the SLF via the Shuttle Carrier Aircraft on March 24, 1979. The runway was first used to land a Space Shuttle on February 11, 1984, when Challenger's STS-41-B mission returned to Earth. This also marked the first landing of a spacecraft at its launch site. Prior to this, all Shuttle landings were performed at Edwards Air Force Base in California (with the exception of STS-3, which landed at White Sands Space Harbor) while the landing facility continued testing and Shuttle crews developed landing skills at White Sands and Edwards, where the margin for error is much greater than SLF and its water hazards. On September 22, 1993, Discovery was the first Space Shuttle to land at night at the SLF on STS-51. A total of 78 Space Shuttle missions landed at the SLF (58% of the 135 missions). The final landing of a Space Shuttle occurred on July 21, 2011, by Atlantis for STS-135. Discovery and Endeavour took off from the SLF on top of the Shuttle Carrier Aircraft for museums in Washington, D.C., and Los Angeles.
