Title: SpaceShipTwo
Content:  SpaceShipTwo is launched from the WhiteKnightTwo launcher aircraft, which takes off from the Mojave Air and Space Port in California during testing. Spaceport America (formerly Southwest Regional Spaceport), a US$212 million spaceport in New Mexico, partly funded by the state government, will become the permanent launch site when commercial launches begin.
Title: Space Shuttle program
Content:  All Space Shuttle missions were launched from the Kennedy Space Center (KSC) in Florida. Some civilian and military circumpolar space shuttle missions were planned for Vandenberg AFB in California. However, the use of Vandenberg AFB for space shuttle missions was canceled after the Challenger disaster in 1986. The weather criteria used for launch included, but were not limited to: precipitation, temperatures, cloud cover, lightning forecast, wind, and humidity. The Shuttle was not launched under conditions where it could have been struck by lightning. The first fully functional orbiter was Columbia (designated OV-102), built in Palmdale, California. It was delivered to 
Title: List of Space Shuttle landing sites
Content:  Three locations in the United States were used as landing sites for the Space Shuttle system. Each site included runways of sufficient length for the slowing-down of a returning spacecraft. The prime landing site was the Shuttle Landing Facility at the Kennedy Space Center in Florida, a purpose-built landing strip. Landings also occurred at Edwards Air Force Base in California, and one took place at White Sands Space Harbor in New Mexico. No Space Shuttle landed on a dry lakebed runway after 1991. Various international landing sites were also available in the event of a Transoceanic Abort Landing (TAL) scenario, as well as other sites in the United States and Canada in case of an East Coast Abort Landing (ECAL) situation. Space Shuttle landings were intended to regularly take place at Vandenberg Air Force Base in California for Department of Defense missions launched from the site, but none occurred due to the cancellation of all launches from Vandenberg.
Title: List of Shuttle Carrier Aircraft flights
Content:  Shuttle Carrier Aircraft ferry flights generally originated at Edwards Air Force Base in California or on one occasion White Sands Space Harbor in New Mexico following missions which landed there, especially in the early days of the Space Shuttle program or when weather at the Shuttle Landing Facility (SLF) at Kennedy Space Center prevented ending missions there. Flights generally ended at the SLF. A number of flights began at Armstrong Flight Research Center following delivery of the orbiter from Rockwell International to NASA from the nearby facilities in Palmdale, California.
Title: Shuttle Down
Content:  In the book, the Space Shuttle Atlantis launches on a polar orbit flight from Vandenberg Air Force Base in Southern California. During the launch, the main engines cut off prematurely and the Shuttle is forced to make an emergency landing on Easter Island. Officials at NASA must manage the technological challenge of recovering the shuttle. Problems include a lack of documents for the astronauts and shuttle, bringing in the crane that is used to lift the Shuttle onto the specially-modified 747 that carries it, widening the runway to accommodate the 747, building turn-arounds on the runway, and bringing in fuel for the plane. A subplot involves efforts by the Soviet Union to take the Shuttle for itself.
Title: Uncrewed spaceflights to the International Space Station
Content:   Cape Canaveral Space Force Station, located in Florida, United States, has been operational since 1950; with its first orbital launch occurring in 1958. All of NASA's crewed Mercury and Gemini missions were launched from the Cape, along with some of the earlier Apollo missions. Cape Canaveral is adjacent to the Kennedy Space Center, where the majority of Apollo missions and all the Space Shuttle missions were launched from. Under contract with NASA, SpaceX launches the Dragon 2 Cargo variant spacecraft to resupply the American portion of the ISS. The Dragon can transport 6000 kg of pressurized and unpressurized cargo and can return 3000 kg to Earth. It is the only uncrewed resupply vehicle capable of returning a payload.
Title: Uncrewed spaceflights to the International Space Station
Content:  The Mid-Atlantic Regional Spaceport, located at Wallops Island, Virginia, United States, is the launch site for the Northrop Grumman Cygnus spacecraft for resupplying the American portion of the ISS.
Title: Shuttle America
Content: Chicago, Illinois - O'Hare International Airport ; Columbus, Ohio - John Glenn Columbus International Airport ; Indianapolis, Indiana - Indianapolis International Airport ; Newark, New Jersey - Newark Liberty International Airport ; New York City-LaGuardia, New York - LaGuardia Airport  
Title: Edwards Air Force Base
Content:  After that time, Kennedy Space Center (KSC) in Florida was favored. This saved the considerable cost of transporting the shuttle from California back to Florida, but Edwards AFB and White Sands Space Harbor continued to serve as backups for the duration of the shuttle program. Shuttles landed at Edwards as recently as 9 August 2005 (STS-114), 22 June 2007 (STS-117), 30 November 2008 (STS-126), 24 May 2009 (STS-125), and 11 September 2009 (STS-128) due to rain and ceiling events at the KSC Shuttle Landing Facility. STS-126 was the only mission to land on temporary runway 04 at Edwards, as the refurbished main runway was operational from STS-119 through to the retirement of the shuttles.
Title: Shuttle Carrier Aircraft
Content:   Ferry flights generally transported the orbiters from Edwards Air Force Base, the shuttle's secondary landing site, to the Shuttle Landing Facility (SLF) at the Kennedy Space Center where the orbiter was processed. This was common in the early days of the Space Shuttle program when weather conditions at the SLF prevented the shuttle from landing there. Some flights started at the Dryden Flight Research Center following delivery of the orbiter from Rockwell International to NASA from the nearby facilities in Palmdale, California. At the end of the Space Shuttle program the SCA was used to deliver the retired orbiters from the Kennedy Space Center to their museums. Discovery was delivered to the Udvar-Hazy Center of the Smithsonian Institution's National Air and Space Museum in Chantilly, Virginia, near Washington, D.C. on April 19, 2012. On April 17, 2012, Discovery was flown atop
