The John F. Kennedy Space Center (Also known as the KSC) was the United States launch site that was used for every NASA human space flight since December 1968.
Although such flights are currently on hiatus, KSC continues to manage and operate unmanned rocket launch facilities for the U.S. government's civilian space program from three pads at the adjoining Cape Canaveral Air Force Station. Its Vehicle Assembly Building (VAB) is the fourth-largest structure in the world by volume, and was the largest when completed in 1965. Located on Merritt Island, Florida, the center is north-northwest of Cape Canaveral on the Atlantic Ocean, midway between Miami and Jacksonville on Florida's Space Coast. It is 34 miles (55 km) long and roughly 6 miles (10 km) wide, covering 219 square miles (570 km2). A total of 13,100 people worked at the center as of 2011. Approximately 2,100 are employees of the federal government; the rest are contractors.
