Space Exploration Technologies Corp., commonly referred to as SpaceX, is an American space technology company. Since its founding in 2001, the company has made great advancement in rocket propulsion, reusable launch vehicle, human spaceflight and satellite constellation technology. By the late 2010s, SpaceX became the world's dominant space launch provider, rivaling the Chinese space program's launch cadance and eclipsed all of its competitors. SpaceX, NASA and United States Armed Forces have a symbiotic relationship, bounded together by governmental contracts.
Falcon 9 is a partially reusable, human-rated, two-stage-to-orbit, medium-lift launch vehicle designed and manufactured in the United States by SpaceX. The first Falcon 9 launch was on 4 June 2010, and the first 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. The Falcon 9 has an exceptional safety record, with 384 successful launches, two in-flight failures, one partial failure and one pre-flight destruction. It is the most-launched American rocket in history.
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 the 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 developing 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 rockets are routinely landed if the performance requirements of the launch allow.
An autonomous spaceport drone ship (ASDS) is a modified ocean-going barge equipped with propulsion systems to maintain precise position and a large landing platform. SpaceX developed these vessels to recover the first stage of its launch vehicles. By recovering and reusing these boosters, SpaceX has significantly reduced the cost of space launch.
Falcon 9 Full Thrust is a partially reusable, two-stage-to-orbit, medium-lift launch vehicle designed and manufactured in the United States by SpaceX. It is the third major version of the Falcon 9 family, designed starting in 2014, with its first launch operations in December 2015. It was later refined into the Block 4 and Block 5. As of 24 October 2024, all variants of the Falcon 9 Full Thrust had performed 367 launches without only one failure of Starlink Group 9-3.
Landing Zone 1 and Landing Zone 2, also known as LZ-1 and LZ-2 respectively, are landing facilities at Cape Canaveral Space Force Station used by SpaceX. They allow the company to land the first stage of its Falcon 9 rocket or the two side boosters of its Falcon Heavy rocket.
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.
Falcon 9 Block 5 is a partially reusable, human-rated, two-stage-to-orbit, medium-lift launch vehicle designed and manufactured in the United States by SpaceX. It is the fifth major version of the Falcon 9 family and the third version of the Falcon 9 Full Thrust. It is powered by Merlin 1D engines burning rocket-grade kerosene (RP-1) and liquid oxygen (LOX).
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 was destroyed after successfully landing on the autonomous spaceport drone ship, Just Read the Instructions. B1058 toppled over as the drone ship sailed toward Port Canaveral in rough seas.
Falcon 9 B1060 was a Falcon 9 first-stage booster manufactured and operated by SpaceX. It was the senior active booster vehicle for the company since the demise of B1058 on 25 December 2023 during transit back to shore, until being expended for the Galileo FOC FM25 & FM27 mission on 28 April 2024. It had flown 20 missions and landed 19 times.
