Orbital Test Vehicle 7 (OTV-7), also referred to as United States Space Force-52 (USSF-52) or USA-349 , [3] [4] is the fourth flight of the second Boeing X-37B, an American unmanned vertical-takeoff, horizontal-landing spaceplane. It was launched to highly elliptical high Earth orbit aboard a Falcon Heavy rocket (for the first time) from LC-39A on 28 December 2023. [5]
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 materials provided by NASA. [6] [7] [8]
OTV-7 is the fourth mission for the second X-37B built, and the seventh X-37B mission overall. It was flown on a Falcon Heavy in the expendable center core-recoverable side cores configuration, and launched from Kennedy Space Center Launch Complex 39A. It is the second classified flight of Falcon Heavy, awarded in June 2018. [9] [10] [11] [12] It is valued at US$130 million, [13] 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. [14] Draft solicitation said the launch was 6,350 kg (14,000 lb) to GTO. [15] A month before launch, the Air Force announced that the mission will fly an X-37B spaceplane. [6]
OTV-7 was deployed into a Highly elliptical HEO orbit of 323 km (201 mi) x 38,838 km (24,133 mi) x 59.1° orbit. [6] [16]
Onboard experiments include NASA's Seeds-2 experiment investigating the effects of space-based radiation on plant seeds during a long-duration spaceflight. [6]
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 reusable launch vehicle has parts that can be recovered and reflown, while carrying payloads from the surface to outer space. Rocket stages are the most common launch vehicle parts aimed for reuse. Smaller parts such as rocket engines and boosters can also be reused, though reusable spacecraft may be launched on top of an expendable launch vehicle. Reusable launch vehicles do not need to make these parts for each launch, therefore reducing its launch cost significantly. However, these benefits are diminished by the cost of recovery and refurbishment.
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 ultimately developing a sustainable colony on 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 January 2024, 17 launches remain. Other future ULA launches will use the new Vulcan Centaur rocket.
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.
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.
USA-212 was the first flight of the Boeing X-37B Orbital Test Vehicle 1, an American robotic vertical-takeoff, horizontal-landing (VTHL) spaceplane. It was launched aboard an Atlas V rocket from Cape Canaveral on 22 April 2010, and operated in low Earth orbit. Its designation is part of the USA series.
The retirement of NASA's Space Shuttle fleet took place from March to July 2011. Discovery was the first of the three active Space Shuttles to be retired, completing its final mission on March 9, 2011; Endeavour did so on June 1. The final shuttle mission was completed with the landing of Atlantis on July 21, 2011, closing the 30-year Space Shuttle program.
