United States Space Force-52 (USSF-52), also referred to as Orbital Test Vehicle 7 (OTV-7), [2] [3] will be the fourth flight of the second Boeing X-37B, an American unmanned vertical-takeoff, horizontal-landing spaceplane. It will be launched to low Earth orbit aboard a Falcon Heavy rocket (for the first time) from LC-39A NET 28 December 2023. [4]
The spaceplane is operated by the Department of the Air Force Rapid Capabilities Office and United States Space Force, which considers the mission classified and as such has not revealed the objectives. The spaceplane will be sent to orbit with a wide range of test and experimentation objectives. These tests include operating in new orbital regimes, experimenting with space domain awareness technologies and investigating the radiation effects to NASA materials. [5] [6] [7]
OTV-7 will be the fourth mission for the second X-37B built, and the seventh X-37B mission overall. It will be flown on a Falcon Heavy in the expendable center core-recoverable side cores configuration, and launched from Kennedy Space Center Launch Complex 39A. It will be the second classified flight of Falcon Heavy, awarded in June 2018. [8] [9] [10] [11] It is valued at US$130 million, [12] increased to $149.2 million in August 2021, due to "a change in the contract requirements" and expected to be completed by 14 April 2022. [13] Draft solicitation said the launch was 6,350 kg (14,000 lb) to GTO. [14] A month before launch, the Air Force announced that the mission will fly an X-37B spaceplane. [5]
OTV-7 will be deployed into a low to high earth orbit. [5]
Onboard experiments include NASA's Seeds-2 experiment investigating the effects of space-based radiation on plant seeds during a long-duration spaceflight. [5]
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.
A spaceplane is a vehicle that can fly and glide like an aircraft in Earth's atmosphere and maneuver like a spacecraft in outer space. To do so, spaceplanes must incorporate features of both aircraft and spacecraft. Orbital spaceplanes tend to be more similar to conventional spacecraft, while sub-orbital spaceplanes tend to be more similar to fixed-wing aircraft. All spaceplanes to date have been rocket-powered for takeoff and climb, but have then landed as unpowered gliders.
National Security Space Launch (NSSL) is a program of the United States Space Force (USSF) intended to assure access to space for United States Department of Defense and other United States government payloads. The program is managed by the Assured Access to Space Directorate (SSC/AA) of the Space Force's Space Systems Command (SSC), in partnership with the National Reconnaissance Office.
Space Exploration Technologies Corp. commonly referred to as SpaceX, is an American spacecraft manufacturer, launch service provider, defense contractor and satellite communications company headquartered in Hawthorne, California. The company was founded in 2002 by Elon Musk with the goal of reducing space transportation costs and to colonize Mars. The company currently operates the Falcon 9 and Falcon Heavy rockets along with the Dragon and Starship spacecraft.
The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. The X-37 is operated by the Department of the Air Force Rapid Capabilities Office, in collaboration with United States Space Force, for orbital spaceflight missions intended to demonstrate reusable space technologies. It is a 120-percent-scaled derivative of the earlier Boeing X-40. The X-37 began as a NASA project in 1999, before being transferred to the United States Department of Defense in 2004. Until 2019, the program was managed by Air Force Space Command.
Atlas V is an expendable launch system and the fifth major version in the Atlas launch vehicle family. It was originally designed by Lockheed Martin, now being operated by United Launch Alliance (ULA), a joint venture between Lockheed Martin and Boeing. It is used for DoD, NASA, and Commercial payloads. It is America's longest-serving active rocket. After 87 launches, in August 2021 ULA announced that Atlas V would be retired, and all 29 remaining launches had been sold. As of 6 October 2023, 17 launches remain.
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.
Falcon 9 is a partially reusable medium-lift launch vehicle that can carry cargo and crew into Earth orbit, designed, manufactured and launched by American aerospace company SpaceX. It can also be used as an expendable heavy-lift launch vehicle. The first Falcon 9 launch was on 4 June 2010. The first Falcon 9 commercial resupply mission to the International Space Station (ISS) launched on 8 October 2012. In 2020 it became the first commercial rocket to ever launch humans to orbit and is currently the only such vehicle capable of doing so. It is the only U.S. rocket currently certified for transporting humans to the ISS. In 2022, it became the U.S. rocket with the most launches in history and with the best safety record, having suffered just one flight failure.
FalconSAT is the United States Air Force Academy's (USAFA) small satellite engineering program. Satellites are designed, built, tested, and operated by Academy cadets. The project is administered by the USAFA Space Systems Research Center under the direction of the Department of Astronautics. Most of the cadets who work on the project are pursuing a bachelor of science degree in astronautical engineering, although students from other disciplines join the project.
