The Shuttle Landing Facility (SLF), also known as Launch and Landing Facility (LLF)[1] (IATA: QQS, ICAO: KTTS, FAA LID: TTS), is an airport located on Merritt Island in Brevard County, Florida, United States.

In addition to ongoing use by NASA, private companies have been utilizing the SLF since the 2011 end of the Space Shuttle program.

[2] (Despite its length, astronaut Jack R. Lousma stated that he would have preferred the runway to be "half as wide and twice as long"[5]) Additionally, the SLF has 1,001 feet (305 m) of paved overruns at each end.

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.

[2] 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.

Discovery and Endeavour took off from the SLF on top of the Shuttle Carrier Aircraft for museums in Washington, D.C., and Los Angeles.

In January 2014 it was announced that Boeing would lease the Orbiter Processing Facility at Kennedy Space Center to enable the U.S. Air Force to efficiently land, recover, refurbish, and re-launch the X-37B uncrewed spacecraft.

Zero Gravity Corporation, which offers flights where passengers experience brief periods of microgravity, has operated from the SLF,[17] as have record-setting attempts by the Virgin Atlantic GlobalFlyer.
