Inside the Launch Control Center, personnel watch as the Saturn V rocket carrying the Apollo 11 astronauts lifts off the launch pad on July 16, 1969. The Launch Control Center (LCC) is a four-story building at NASA's Kennedy Space Center on Merritt Island, Florida, used to manage launches of spacecraft from Kennedy Space Center Launch Complex 39. The LCC handles all American space flights with human crews. Attached to the southeast corner of the Vehicle Assembly Building, the LCC contains offices; telemetry, tracking, and instrumentation equipment; the automated Launch Processing System; and four firing rooms. LCC has conducted launches since the unmanned Apollo 4 launch in 1967. LCC's first launch with a human crew was Apollo 8 on December 21, 1968. NASA's Space Shuttle program also used LCC. NASA has renovated the center for the upcoming Space Launch System (SLS) missions, which are scheduled to begin in 2020 with Exploration Mission-1.
