The Space Launch Complex 46 (SLC-46), previously Launch Complex 46 (LC-46), is a launch complex at Cape Canaveral Space Force Station operated under license by Space Florida previously used for Athena rocket launches. It has been used by Astra, which will continue the use with Rocket 4 and maybe 5 and will be used by ABL Space Systems for the near-term use by RS1.
This complex was built as part of the U.S. Navy's Trident II submarine-launch missile development effort. Construction was underway by early February 1984, with the first Trident II launch LC-46 occurring on 15 January 1987. A total of 19 Trident IIs were launched from the site between 15 January 1987 and 27 January 1989. After this, all subsequent Trident II testing took place at sea, and the site was deactivated. [1]
During the construction of then-called LC-46, the nearby sounding rocket complex LC-43 was demolished. Its operations were transferred to LC-47.
In 1997, Space Florida began operations at the site, and was opened for commercial space operations. Lockheed Martin launched an Athena II and an Athena I from the pad in 1998 and 1999 respectively. The Athena II, launched January 7, 1998, carried the Lunar Prospector spacecraft which orbited the Moon. On January 27, 1999, the Athena I lifted off with Taiwan's first satellite, ROCSAT-1, carrying experimental communications, ocean imagery, and ionospheric studies instruments.
In March 2010, the USAF 45th Space Wing issued Real Property Licenses to Space Florida for Launch Complexes 36 and 46 at Cape Canaveral Air Force Station. [2] [3] On July 1, 2010, the Federal Aviation Administration approved a Launch Site Operator's License for commercial launches at Launch Complex 46. [4]
On September 24, 2010, the Economic Development Commission of Florida's Space Coast was awarded a $500,000 Defense Infrastructure Grant from the State of Florida to be used for critical communications upgrades at SLC-46. [5] In early 2014, Space Florida contracted with Alliant Techsystems (ATK) to begin phase three of the communications infrastructure refurbishment, with completion expected to take one year. [6]
In July 2015, the U.S. Air Force and Orbital ATK announced a Minotaur IV launched from SLC-46 would be used for the ORS-5 mission in 2017. [7] [8] ORS-5 was successfully launched on August 26, 2017. [9]
On July 2, 2019, NASA launched a repurposed Peacekeeper missile from SLC-46, carrying the Orion spacecraft for the Ascent Abort-2 mission. [10] The mission's goal was to demonstrate and qualify the Orion Launch Abort System (LAS) that will allow the astronaut crew to safely escape in the event of an emergency during launch pad operations, through the ascent phase of the Orion vehicle.
On December 6, 2021, Astra announced plans to launch its small orbital rockets from SLC-46 as soon as February 2022. [11] The company was planning for a launch cadence of once a month for two years. [12]
On 10 February 2022, the first Astra launch from SLC-46 resulted in failure. After two previous scrubbed launch attempts in the preceding days, the launch of the rocket occurred nominally. However, first stage separation failed, leading to the second stage to spin out of control, and the rocket and payload were lost. [13]
On 12 June 2022, the second Astra launch from SLC-46 also resulted in failure. Astra's Rocket 3.3 vehicle (serial number LV0010) carrying two TROPICS CubeSats for NASA failed to reach orbit and the satellites were lost. [14]
The John F. Kennedy Space Center, located on Merritt Island, Florida, is one of the National Aeronautics and Space Administration's (NASA) ten field centers. Since 1968, KSC has been NASA's primary launch center of American spaceflight, research, and technology. Launch operations for the Apollo, Skylab and Space Shuttle programs were carried out from Kennedy Space Center Launch Complex 39 and managed by KSC. Located on the east coast of Florida, KSC is adjacent to Cape Canaveral Space Force Station (CCSFS). The management of the two entities work very closely together, share resources, and operate facilities on each other's property.
Cape Canaveral Space Force Station (CCSFS) is an installation of the United States Space Force's Space Launch Delta 45, located on Cape Canaveral in Brevard County, Florida.
Delta IV was a group of five expendable launch systems in the Delta rocket family. It flew 45 missions from 2002 to 2024. Originally designed by Boeing's Defense, Space and Security division for the Evolved Expendable Launch Vehicle (EELV) program, the Delta IV became a United Launch Alliance (ULA) product in 2006. The Delta IV was primarily a launch vehicle for United States Air Force (USAF) military payloads, but was also used to launch a number of United States government non-military payloads and a single commercial satellite.
Minotaur-C, formerly known as Taurus or Taurus XL, is a four stage solid fueled launch vehicle built in the United States by Orbital Sciences and launched from SLC-576E at California's Vandenberg Air Force Base. It is based on the air-launched Pegasus rocket from the same manufacturer, utilizing a "zeroth stage" in place of an airplane. The Minotaur-C is able to carry a maximum payload of around 1458 kg into a low Earth orbit (LEO).
The Minotaur is a family of United States solid-fuel launch vehicles repurposed from retired Minuteman and Peacekeeper model intercontinental ballistic missiles. Built by Northrop Grumman under the Space Force's Rocket Systems Launch Program, these vehicles are used for various space and test launch missions.
United Launch Alliance, LLC (ULA) is an American launch service provider formed in December 2006 as a joint venture between Lockheed Martin Space and Boeing Defense, Space & Security. The company designs, assembles, sells and launches rockets, but the company subcontracts out the production of rocket engines and solid rocket boosters.
Space Launch Complex 37 (SLC-37), previously Launch Complex 37 (LC-37), is a launch complex on Cape Canaveral Space Force Station, Florida. Construction began in 1959 and the site was accepted by NASA to support the Saturn I program in 1963. The complex consists of two launch pads. LC-37A has never been used, but LC-37B launched uncrewed Saturn I flights and was modified and launched Saturn IB flights, including the first (uncrewed) test of the Apollo Lunar Module in space. It was deactivated in 1972. In 2001 it was modified as the launch site for Delta IV, a launch system operated by United Launch Alliance.
Space Launch Complex 17 (SLC-17), previously designated Launch Complex 17 (LC-17), was a launch site at Cape Canaveral Air Force Station (CCAFS), Florida used for Thor and Delta launch vehicles launches between 1958 and 2011.
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.
Launch Complex 36 (LC-36) is a launch complex located at the Cape Canaveral Space Force Station in Florida. Historically, it served as a launch pad for Atlas rockets operated by NASA and the U.S. Air Force from 1962 to 2005.
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 August 2024, the pad has hosted over 200 Falcon 9 launches.
Missile Row was a nickname given in the 1960s to the eight SM-65 Atlas and HGM-25A Titan I launch complexes at the middle area of Cape Canaveral Space Force Station (CCSFS), historically used by the United States Air Force and NASA. Operated by the 45th Space Wing since 1949, it was the site of all fourteen Mercury-Atlas and Gemini launches, as well as many other early missile tests, Department of Defense (DoD) launches, and NASA launches. For the DoD, it played a secondary role to Vandenberg Air Force Base in California, but was the launch site for many NASA unmanned space probes, as those spacecraft were typically launched on military launchers.
The Operationally Responsive Space Office is a joint initiative of the United States Department of Defense (DoD). The "stand up" of the office took place 21 May 2007 at Kirtland Air Force Base. The first director of the ORS Office was Col. Kevin McLaughlin, who was also the commander of the Space Development and Test Wing located at Kirtland. The ORS Office focuses on providing quick-response tactical space-based capabilities; utilizing smaller satellites, such as the Tactical Satellite Program and smaller launch vehicles.
