Kennedy Space Center Launch Complex 39A

Launch Complex 39 (LC-39) is a rocket launch site at the John F. Kennedy Space Center on Merritt Island in Florida, United States. The site and its collection of facilities were originally built as the Apollo program's "Moonport" and later modified for the Space Shuttle program. Launch Complex 39 consists of three launch sub-complexes or "pads"—39A, 39B, and 39C—a Vehicle Assembly Building (VAB), a Crawlerway used by crawler-transporters to carry mobile launcher platforms between the VAB and the pads, Orbiter Processing Facility buildings, a Launch Control Center which contains the firing rooms, a news facility famous for the iconic countdown clock seen in television coverage and photos, and various logistical and operational support buildings. SpaceX leases Launch Complex 39A from NASA and has modified the pad to support Falcon 9 and Falcon Heavy launches. NASA began modifying Launch Complex 39B in 2007 to accommodate the now defunct Constellation program, and is currently prepared for the Artemis program, which was first launched in November 2022. A pad to be designated 39C, which would have been a copy of pads 39A and 39B, was originally planned for Apollo but never built. A smaller pad, also designated 39C, was constructed from January to June 2015, to accommodate small-lift launch vehicles. NASA launches from pads 39A and 39B have been supervised from the NASA Launch Control Center (LCC), located 3 miles (4.8 km) from the launch pads. LC-39 is one of several launch sites that share the radar and tracking services of the Eastern Test Range.

The Crawlerway is a 130-foot-wide (40 m) double pathway at the Kennedy Space Center in Florida. It runs between the Vehicle Assembly Building and the two launch pads at Launch Complex 39. It has a length of 3.4 and 4.2 miles (5.5 and 6.8 km) to Pad 39A and Pad 39B, respectively. A seven-foot (2 m) bed of stones lies beneath a layer of asphalt and a surface made of Alabama river rocks. The Crawlerway was originally designed to support the weight of the Saturn V rocket and its payload, plus the Launch Umbilical Tower and mobile launcher platform, atop a crawler-transporter during the Apollo program. It was also used from 1981 to 2011 to transport the lighter Space Shuttles to their launch pads. Construction of the Crawlerway connected Merritt Island with the mainland, forming a peninsula. The main vehicle access road to and from the launch pads, the Saturn Causeway, runs alongside the Crawlerway.

Launch Complex 39B (LC-39B) is the second of Launch Complex 39's three launch pads, located at NASA's Kennedy Space Center in Merritt Island, Florida. The pad, along with Launch Complex 39A, was first designed for the Saturn V launch vehicle, which at the time was the United States' most powerful rocket. Typically used to launch NASA's crewed spaceflight missions since the late 1960s, the pad is currently configured for use by the agency's Space Launch System rocket, a Shuttle-derived launch vehicle which is currently used in the Artemis program and subsequent Moon to Mars campaigns. The pad had also been leased by NASA to aerospace company Northrop Grumman, for use as a launch site for their Shuttle-derived OmegA launch vehicle, for National Security Space Launch flights and commercial launches, before the OmegA program was cancelled.

Space Launch Complex 41 (SLC-41), previously Launch Complex 41 (LC-41), is an active launch site at Cape Canaveral Space Force Station. As of 2024, the site is used by United Launch Alliance (ULA) for Atlas V and Vulcan Centaur launches. Previously, it had been used by the United States Air Force for Titan IIIC, Titan IIIE, and Titan IV launches.

The Astronaut Beach House is a two-story house built in 1962 as a part of the then Neptune Beach subdivision at Cape Canaveral, Florida. NASA purchased the development through eminent domain for $31,500 in 1963 to accommodate the expanding Kennedy Space Center, and other private homes were removed. Unlike a nearby gas station and store, the home was left and has served as a social gathering point for astronauts prior to launch. Officially it was called the Astronaut Training and Rehabilitation Building then, today it is officially titled the Kennedy Space Center Conference Center. Throughout its history with NASA it has been known as the Astronaut Beach House or simply The Beach House. It stands 50 meters (160 ft) back from the shoreline directly in between Pads 40 and 41. It also serves as a private conference center, and for astronauts and their families for private gatherings and barbecues before launch. The house contains memorabilia including wine bottles signed by crew members identified by mission decals.

The Launch Complex 39 Press Site is a news media facility at Launch Complex 39 at the John F. Kennedy Space Center (KSC) on Merritt Island, Florida where journalists have observed every U.S. crewed space launch since Apollo 8 in 1968. The site is just south of the Vehicle Assembly Building (VAB); 3 miles (4.8 km) west-southwest of Pad A, and 3.4 miles (5.4 km) southwest of Pad B. The site includes an elevated mound where news media facilities are located, as well as the KSC News Center and several smaller support buildings. The News Center is 8,700 square feet (810 m2) and contains 15 site support offices, media workspace, and a media library. Current media buildings include CBS, NBC, Florida Today and The Orlando Sentinel; and trailers for The Associated Press and Reuters. The 100-seat auditorium in the audio-video support building, where pre- and post-launch news conferences are held, is named for former CNN correspondent John Holliman, who covered space exploration until his death in 1998. It was built in 1980. A large illuminated digital countdown clock and a flagpole flying an American flag on the edge of the turning basin have often been included in television coverage and launch photos. Before a launch, the clock counts down, showing the remaining time until T-zero in hours, minutes and seconds (–00:00:00). After launch, the clock counts forward in Mission Elapsed Time for several hours. The flagpole also flew a smaller Space Shuttle Orbiter-specific flag below the American flag on launch day during the final years of the Space Shuttle Program.

The Rocco A. Petrone Launch Control Center (commonly known as just the Launch Control Center or LCC) is a four-story building at NASA's Kennedy Space Center on Merritt Island, Florida, used to manage launches of launch vehicles from Kennedy Space Center Launch Complex 39. Attached to the southeast corner of the Vehicle Assembly Building, the LCC contains offices; telemetry, tracking, and instrumentation equipment; and firing rooms. LCC has conducted launches since the unmanned Apollo 4 (Apollo-Saturn 501) launch on November 9, 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 Space Launch System (SLS) missions, which began in 2022 with Artemis 1. In February 2022, the center was renamed after former launch director Rocco A. Petrone.

The Vehicle Assembly Building (originally the Vertical Assembly Building), or VAB, is a large building at NASA's Kennedy Space Center (KSC) in Florida, designed to assemble large pre-manufactured space vehicle components, such as the massive Saturn V, the Space Shuttle and the Space Launch System, and stack them vertically onto one of three mobile launcher platforms used by NASA. As of March 2022, the first Space Launch System (SLS) rocket was assembled inside in preparation for the Artemis I mission, launched on November 16, 2022. At 129,428,000 cu ft (3,665,000 m3), it is the eighth-largest building in the world by volume as of 2022. The building is at Launch Complex 39 at KSC, 149 miles (240 km) south of Jacksonville, 219 miles (352 km) north of Miami, and 50 miles (80 km) due east of Orlando, on Merritt Island on the Atlantic coast of Florida. The VAB is the largest single-story building in the world, was the tallest building (526 ft or 160 m) in Florida until 1974, and is the tallest building in the United States outside an urban area.

The following buildings were added to the National Register of Historic Places as part of the John F. Kennedy Space Center MPS Multiple Property Submission (or MPS). This is a partial list of historic places at KSC; full list available via KSC's Environmental Planning - Cultural Resources.

Space Launch Complex 40 (SLC-40), sometimes referred to as "Slick Forty," is a launch pad located at Cape Canaveral Space Force Station in Florida. Initially opened as Launch Complex 40 (LC-40) and used by the United States Air Force for 55 launches of rockets from the Titan family between 1965 and 2005. In 2007, SpaceX acquired a lease for SLC-40 and has since transformed the complex into a high-volume launch site for the Falcon 9 rocket. As of November 2024, the pad has hosted over 220 Falcon 9 launches. A major setback occurred in 2016 when a catastrophic explosion during a static fire test heavily damaged the facility. After extensive repairs and upgrades, SLC-40 returned to service in December 2017. To further enhance its capabilities, a tower and access arm were added in 2023 to support SpaceX's crewed missions.
