The John F. Kennedy Space Center (KSC) is the NASA space vehicle launch facility and Launch Control Center (spaceport) on Merritt Island, Brevard County, Florida, United States. The site is near Cape Canaveral, midway between Miami and Jacksonville, Florida. It is long and around wide, covering . A total of 13,500 people work at the site as of early 2008. There is a visitor center and public tours and KSC is a major tourist destination for visitors to Florida. Because much of KSC is a restricted area and only 9 percent of the land is developed, the site also serves as an important wildlife sanctuary; Mosquito Lagoon, Indian River, Merritt Island National Wildlife Refuge and Canaveral National Seashore are also features of this area. The area receives more lightning strikes than any other place in the U.S., causing NASA to spend millions of dollars to avoid strikes during launch.

Operations are currently controlled from Launch Complex 39, the location of the Vehicle Assembly Building. to the east of the assembly building are the two launch pads. south is the KSC Industrial Area, where many of the Center's support facilities and the administrative Headquarters Building are located.

Kennedy Space Center's only launch operations are at Launch Complex 39. All other launch operations take place at the adjacent Cape Canaveral Air Force Station (CCAFS), which is operated by the US Air Force. The center employs about 15,000 civil servants and contractors.
