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 booster is a rocket used either in the first stage of a multistage launch vehicle or in parallel with longer-burning sustainer rockets to augment the space vehicle's takeoff thrust and payload capability. Boosters are traditionally necessary to launch spacecraft into low Earth orbit, and are especially important for a space vehicle to go beyond Earth orbit. The booster is dropped to fall back to Earth once its fuel is expended, a point known as booster engine cut-off (BECO).
A launch vehicle is typically a rocket-powered vehicle designed to carry a payload from Earth's surface or lower atmosphere to outer space. The most common form is the ballistic missile-shaped multistage rocket, but the term is more general and also encompasses vehicles like the Space Shuttle. Most launch vehicles operate from a launch pad, supported by a launch control center and systems such as vehicle assembly and fueling. Launch vehicles are engineered with advanced aerodynamics and technologies, which contribute to high operating costs.
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 launch humans to orbit and remains the only such vehicle. It is the only U.S. rocket 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.
Rocket Lab USA, Inc. is a publicly traded aerospace manufacturer and launch service provider that operates and launches lightweight Electron orbital rockets used to provide dedicated launch services for small satellites as well as a suborbital variant of Electron called HASTE. The company plans to build a larger Neutron rocket as early as 2024. Electron rockets have launched 44 times from either Rocket Lab's Launch Complex 1 in New Zealand or at the Mid-Atlantic Regional Spaceport in Wallops Island, Virginia, United States. Rocket Lab has launched one HASTE rocket to date from Wallops Island, Virginia.
Falcon Heavy is a partially reusable super heavy-lift launch vehicle that can carry cargo into Earth orbit, and beyond. It is designed, manufactured and launched by American aerospace company SpaceX.
SpaceX has privately funded the development of orbital launch systems that can be reused many times, similar to the reusability of aircraft. SpaceX has developed technologies over the last decade to facilitate full and rapid reuse of space launch vehicles. The project's long-term objectives include returning a launch vehicle first stage to the launch site within minutes and to return a second stage to the launch pad, following orbital realignment with the launch site and atmospheric reentry in up to 24 hours. SpaceX's long term goal would have been reusability of both stages of their orbital launch vehicle, and the first stage would be designed to allow reuse a few hours after return. Development of reusable second stages for Falcon 9 was later abandoned in favor of developing Starship, however, SpaceX developed reusable payload fairings for the Falcon 9.
Falcon 9 flight 10 was a Falcon 9 space launch that occurred on July 14, 2014. It was the fifth launch of the Falcon 9 v1.1 launch vehicle and carried six Orbcomm-OG2 telecommunication satellites. All six 172-kilogram-mass (379 lb) satellites were successfully deployed.
The Falcon 9 first-stage landing tests were a series of controlled-descent flight tests conducted by SpaceX between 2013 and 2016. Since 2017, the first stage of Falcon 9 missions has been routinely landed if the rocket performance allowed it, and if SpaceX chose to recover the stage.
Falcon 9 flight 20 was a Falcon 9 space launch that occurred on 22 December 2015 at 01:29:00 UTC. It was the first time that the first stage of an orbital rocket made a successful return and vertical landing.
Falcon 9 Full Thrust is a partially reusable medium-lift launch vehicle, designed and manufactured by SpaceX. It was first designed in 2014–2015, with its first launch operations in December 2015. As of 2 April 2024, Falcon 9 Full Thrust had performed 297 launches without any failures. Based on the Laplace point estimate of reliability, this rocket is the most reliable orbital launch vehicle in operation.
New Glenn is a heavy-lift orbital launch vehicle developed by Blue Origin, named after NASA astronaut John Glenn, the first American astronaut to orbit Earth. Design work on the vehicle began in 2012; illustrations of the vehicle, and the high-level specifications, were initially publicly unveiled in September 2016. The full vehicle was first unveiled on a launch pad on 21 February 2024. New Glenn is a two-stage rocket with a diameter of 7 m (23 ft). Its first stage will be powered by seven BE-4 engines that are also being designed and manufactured by Blue Origin. It will launch from Cape Canaveral Launch Complex 36.
Firefly Alpha is a two-stage orbital expendable launch vehicle developed by the American company Firefly Aerospace to compete in the commercial small satellite launch market. Alpha is intended to provide launch options for both full vehicle and rideshare customers.
Curie is a liquid-propellant rocket engine designed and manufactured by Rocket Lab. A bipropellant is used for the propulsion of the third stage/kick stage of the Electron rocket, as well as the Photon. The composition of the propellant is a trade secret.
Orbital Express Launch Ltd., or Orbex, is a United Kingdom-based aerospace company that is developing a small commercial orbital rocket called Prime. Orbex is headquartered in Forres, Moray, in Scotland and has subsidiaries in Denmark and Germany. Its future launch complex, Sutherland spaceport, is being built on the A' Mhòine peninsula in the county of Sutherland, northern Scotland.
Falcon 9 booster B1048 was a reusable orbital-class Block 5 Falcon 9 first-stage booster manufactured by SpaceX. B1048 was the third Falcon 9 Block 5 to fly and the second Block 5 booster to re-fly. It became the second orbital-class booster to fly a third time and is the first booster ever to be launched five times. B1048 service came to an end on its fifth flight when an engine shut down prematurely on launch. Whilst the primary mission was unaffected and the Starlink payload deployed successfully, B1048 was unable to land. In a subsequent investigation, SpaceX found that isopropyl alcohol, used as cleaning fluid, was trapped and ignited causing the engine to be shut down. To address the issue, in a following launch SpaceX indicated that the cleaning process was not done.
