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.
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.
Vertical takeoff, vertical landing (VTVL) is a form of takeoff and landing for rockets. Multiple VTVL craft have flown. The most successful VTVL vehicle was the Apollo Lunar Module which delivered the first humans to the Moon. Building on the decades of development SpaceX's utilised the VTVL concept for its flagship Falcon 9 first stage, which is delivered over two hundred successful powered landings so far.
Space Launch Complex 4 (SLC-4) is a launch and landing site at Vandenberg Space Force Base, California, U.S. It has two pads, both of which are used by SpaceX for Falcon 9, one for launch operations, and other as Landing Zone 4 (LZ-4) for SpaceX landings.
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 the development of Starship, however, SpaceX developed reusable payload fairings for the Falcon 9.
SpaceX CRS-6, also known as SpX-6, was a Commercial Resupply Service mission to the International Space Station, contracted to NASA. It was the eighth flight for SpaceX's uncrewed Dragon cargo spacecraft and the sixth SpaceX operational mission contracted to NASA under a Commercial Resupply Services contract. It was docked to the International Space Station from 17 April to 21 May 2015.
Falcon 9 v1.1 was the second version of SpaceX's Falcon 9 orbital launch vehicle. The rocket was developed in 2011–2013, made its maiden launch in September 2013, and its final flight in January 2016. The Falcon 9 rocket was fully designed, manufactured, and operated by SpaceX. Following the second Commercial Resupply Services (CRS) launch, the initial version Falcon 9 v1.0 was retired from use and replaced by the v1.1 version.
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.
An autonomous spaceport drone ship (ASDS) is an ocean-going vessel derived from a deck barge, outfitted with station-keeping engines and a large landing platform, and is autonomously positioned when on station for a landing. Construction of the drone ships was commissioned by aerospace company SpaceX to allow recovery of launch vehicle boosters at sea for missions that do not carry sufficient fuel to return to the launch site after boosting spacecraft onto an orbital or interplanetary trajectory.
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 4 March 2024, Falcon 9 Full Thrust had performed 285 launches without any failures. Based on the Laplace point estimate of reliability, this rocket is the most reliable orbital launch vehicle in operation.
Landing Zone 1 and Landing Zone 2, also known as LZ-1 and LZ-2 respectively, are landing facilities on Cape Canaveral Space Force Station for recovering components of SpaceX's VTVL reusable launch vehicles. LZ-1 and LZ-2 were built on land leased in February 2015, on the site of the former Cape Canaveral Launch Complex 13. SpaceX built Landing Zone 2 at the facility to have a second landing pad, allowing two Falcon Heavy boosters to land simultaneously.
SpaceX Dragon C106 is a Dragon space capsule built by SpaceX. It is the first reused SpaceX Dragon capsule to be reflown into space, having its second launch in 2017. C106 was first used on CRS-4, and then used again for the CRS-11 and CRS-19 missions. It was the second capsule after C108 to be used a third time, marking a milestone in SpaceX's drive to reduce space launch costs through reusing hardware.
Falcon 9 B1046 was a reusable Falcon 9 first-stage booster manufactured by SpaceX. It flew four times between 2018 and 2020 before it was expended during a successful abort test of the Crew Dragon. It was the first rocket of the final Falcon 9 upgrade, Block 5.
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.
A floating launch vehicle operations platform is a marine vessel used for launch or landing operations of an orbital launch vehicle by a launch service provider: putting satellites into orbit around Earth or another celestial body, or recovering first-stage boosters from orbital-class flights by making a propulsive landing on the platform.
Falcon 9 booster B1058 was a reusable Falcon 9 Block 5 first-stage booster manufactured by SpaceX. B1058 was the first Falcon 9 booster to fly fourteen, fifteen, sixteen, seventeen, eighteen and nineteen times and broke a turnaround record on its later flights. Its first flight was for Crew Dragon Demo-2, the first crewed orbital spaceflight by a private company. The booster was the first and only Falcon 9 booster to feature NASA's worm logo and meatball insignia, which was reintroduced after last being used in 1992. The booster's service ended shortly after its nineteenth successful landing when it toppled over on the droneship due to high winds and rough seas.
Falcon 9 B1060 is a Falcon 9 first-stage booster manufactured and operated by SpaceX. It is the senior active rocket for the company since the demise of B1058 on 25 December 2023. As of 24 February 2024, it has flown to space and landed 18 times, matching the record of B1062.
