Space Exploration Technologies Corp., doing business as SpaceX, is a private American aerospace manufacturer and space transportation services company headquartered in Hawthorne, California. It was founded in 2002 by entrepreneur Elon Musk with the goal of reducing space transportation costs and enabling the colonization of Mars.[9][10][11] SpaceX has since developed the Falcon launch vehicle family and the Dragon spacecraft family, which both currently deliver payloads into Earth orbit.
SpaceX's achievements include the first privately funded liquid-propellant rocket to reach orbit (Falcon 1 in 2008),[12] the first private company to successfully launch, orbit, and recover a spacecraft (Dragon in 2010), the first private company to send a spacecraft to the International Space Station (Dragon in 2012),[13] the first propulsive landing for an orbital rocket (Falcon 9 in 2015), the first reuse of an orbital rocket (Falcon 9 in 2017), and the first private company to launch an object into orbit around the sun (Falcon Heavy's payload of a Tesla Roadster in 2018). SpaceX has flown 14 resupply missions to the International Space Station (ISS) under a partnership with NASA.[14] NASA also awarded SpaceX a further development contract in 2011 to develop and demonstrate a human-rated Dragon, which would be used to transport astronauts to the ISS and return them safely to Earth.
SpaceX announced in 2011 that it was beginning a reusable launch system technology development program. In December 2015, the first Falcon 9 was flown back to a landing pad near the launch site, where it successfully accomplished a propulsive vertical landing. This was the first such achievement by a rocket for orbital spaceflight.[16] In April 2016, with the launch of CRS-8, SpaceX successfully vertically landed a first stage on an ocean drone ship landing platform.[17] In May 2016, in another first, SpaceX again landed a first stage, but during a significantly more energetic geostationary transfer orbit mission.[18] In March 2017, SpaceX became the first to successfully re-launch and land the first stage of an orbital rocket.
SpaceX plans to launch its Dragon 2 spacecraft in January 2019 and to launch its first crewed spacecraft Dragon 2 in June 2019.
In September 2016, CEO Elon Musk unveiled the mission architecture of the Interplanetary Transport System program, an ambitious privately funded initiative to develop spaceflight technology for use in crewed interplanetary spaceflight. In 2017, Musk unveiled an updated configuration of the system, now named the BFR, which will be the largest rocket in history and will be fully reusable when it debuts in the early 2020s.[21] BFR is the acronym for Big Falcon Rocket.[22] SpaceX revealed on Twitter that the world’s first private passenger, who was later revealed to be Yusaku Maezawa, has been signed to fly across the moon in the BFR rocket.

Goals
Musk has stated that one of his goals is to decrease the cost and improve the reliability of access to space, ultimately by a factor of ten.[48] CEO Elon Musk said: "I believe $500 per pound ($1,100/kg) or less is very achievable."[49]

In 2017, SpaceX formed a subsidiary, The Boring Company,[4] and began work to construct a short underground test tunnel on and adjacent to the SpaceX headquarters and manufacturing facility, utilizing a small number of SpaceX employees,[53] which was completed in May 2018.[54][55]
At the 2017 International Astronautical Congress in Adelaide, Australia, Musk announced his plans to build large spaceships to reach Mars.[56] Using the BFR, Musk plans to land at least two uncrewed cargo ships to Mars in 2022. The first missions will be used to seek out sources of water and build a propellant plant. In 2024, Musk plans to fly four additional ships to Mars including the first people. From there, additional missions would work to establish a Mars colony.[10][57] Musk's advocacy for the long-term settlement of Mars, goes far beyond what SpaceX projects to build;[58][59][60] a successful colonization would ultimately involve many more economic actors—whether individuals, companies, or governments—to facilitate the growth of the human presence on Mars over many decades.[61][62][63]
Achievements
Landmark achievements of SpaceX include:[64]- The first privately funded liquid-fueled rocket to reach orbit (Falcon 1 flight 4—September 28, 2008)
- The first privately developed liquid-fueled rocket to put a commercial satellite in orbit (RazakSAT on Falcon 1 flight 5—July 14, 2009)
- The first private company to successfully launch, orbit, and recover a spacecraft (Dragon capsule on COTS demo flight 1—December 9, 2010)
- The first private company to send a spacecraft to the International Space Station (Dragon C2+—May 25, 2012)
- The first private company to send a satellite into geosynchronous orbit (SES-8 on Falcon 9 flight 7—December 3, 2013)
- The first landing of an orbital rocket's first stage on land (Falcon 9 flight 20—December 22, 2015)
- The first landing of an orbital rocket's first stage on an ocean platform (Falcon 9 flight 23—April 8, 2016)
- The first relaunch and landing of a used orbital rocket stage (B1021 on Falcon 9 flight 32—March 30, 2017)[65]
- The first controlled flyback and recovery of a payload fairing (Falcon 9 flight 32—March 30, 2017)[66]
- The first reflight of a commercial cargo spacecraft. (Dragon C106 on CRS-11 mission—June 3, 2017)[67]
Setbacks
In March 2013, a Dragon spacecraft in orbit developed issues with its thrusters that limited its control capabilities. SpaceX engineers were able to remotely clear the blockages within a short period, and the spacecraft was able to successfully complete its mission to and from the International Space Station.In June 2015, CRS-7 launched a Dragon capsule atop a Falcon 9 to resupply the International Space Station. All telemetry readings were nominal until 2 minutes and 19 seconds into the flight, when a loss of helium pressure was detected and a cloud of vapor appeared outside the second stage. A few seconds after this, the second stage exploded. The first stage continued to fly for a few seconds before disintegrating due to aerodynamic forces. The capsule was thrown off and survived the explosion, transmitting data until it was destroyed on impact.[68] Later it was revealed that the capsule could have landed intact if it had software to deploy its parachutes in case of a launch mishap.[69] The problem was discovered to be a failed 2-foot-long steel strut purchased from a supplier to hold a helium pressure vessel that broke free due to the force of acceleration.[70] This caused a breach and allowed high-pressure helium to escape into the low-pressure propellant tank, causing the failure. The Dragon software issue was also fixed in addition to an analysis of the entire program in order to ensure proper abort mechanisms are in place for future rockets and their payload.[71]
In September 2016, a Falcon 9 exploded during a propellant fill operation for a standard pre-launch static fire test.[72][73] The payload, the Spacecom Amos-6 communications satellite valued at $200 million, was destroyed.[74] Musk described the event as the "most difficult and complex failure" ever in SpaceX's history; SpaceX reviewed nearly 3,000 channels of telemetry and video data covering a period of 35–55 milliseconds for the postmortem.[75] Musk reported the explosion was caused by the liquid oxygen that is used as propellant turning so cold that it solidified and it ignited with carbon composite helium vessels.[76] Though not considered an unsuccessful flight, the rocket explosion sent the company into a four-month launch hiatus while it worked out what went wrong, and SpaceX returned to flight in January 2017.[77]
In February 2018, the Falcon Heavy center core crashed about 100 meters from its target, the autonomous spaceport drone ship, "Of Course I Still Love You", when two of the three engines did not fire during the final landing burn. Elon Musk said on the disaster, "Not enough ignition fluid to light the outer two engines after several three engine relights," Musk wrote. "Fix is pretty obvious." The other two boosters were able to successfully simultaneously land on a pair of landing pads at Cape Canaveral Air Force Station. [78]
Ownership, funding and valuation
In August 2008, SpaceX accepted a $20 million investment from Founders Fund.[79] In early 2012, approximately two-thirds of the company were owned by its founder[80] and his 70 million shares were then estimated to be worth $875 million on private markets,[81] which roughly valued SpaceX at $1.3 billion as of February 2012.[82] After the COTS 2+ flight in May 2012, the company private equity valuation nearly doubled to $2.4 billion.[83][84] In January 2015, SpaceX raised $1 billion in funding from Google and Fidelity, in exchange for 8.333% of the company, establishing the company valuation at approximately $12 billion. Google and Fidelity joined prior investors Draper Fisher Jurvetson, Founders Fund, Valor Equity Partners and Capricorn.[85][86] In July 2017, the Company raised US$350m at a valuation of US$21 billion.[87]As of May 2012, SpaceX had operated on total funding of approximately $1 billion in its first ten years of operation. Of this, private equity provided about $200M, with Musk investing approximately $100M and other investors having put in about $100M (Founders Fund, Draper Fisher Jurvetson, ...).[88] The remainder has come from progress payments on long-term launch contracts and development contracts. By March 2018, SpaceX had contracts for 100 launch missions, and each of those contracts provide down payments at contract signing, plus many are paying progress payments as launch vehicle components are built in advance of mission launch, driven in part by US accounting rules for recognizing long-term revenue.[45]

Successful SpaceX launches by year[89]
Spacecraft and flight hardware
SpaceX currently manufactures three broad classes of rocket engine in-house: the kerosene fueled Merlin engines, the methane fueled Raptor engines, and the hypergolic fueled Draco/SuperDraco vernier thrusters. The Merlin powers their two main space launch vehicles: the Falcon 9,[91] which flew successfully into orbit on its maiden launch in June 2010[92] and the super-heavy class Falcon Heavy, which was launched for the first time on February 6, 2018. SpaceX also manufactures the Dragon, a pressurized orbital spacecraft that is launched on top of a Falcon 9 booster to carry cargo to low Earth orbit, and the follow-on Dragon 2 spacecraft, or Crew Dragon, currently in the process of being human-rated through a variety of design reviews and flight tests that began in 2014.[93][94]

Rocket engines
Since the founding of SpaceX in 2002, the company has developed three families of rocket engines — Merlin and the retired Kestrel for launch vehicle propulsion, and the Draco control thrusters. SpaceX is currently developing two further rocket engines: SuperDraco and Raptor. SpaceX is currently the world’s most prolific producer of liquid fuel rocket engines.[95]Merlin is a family of rocket engines developed by SpaceX for use on its Falcon rocket family. Merlin engines use LOX and RP-1 as propellants in a gas-generator power cycle. The Merlin engine was originally designed for sea recovery and reuse. The injector at the heart of Merlin is of the pintle type that was first used in the Apollo Program for the lunar module landing engine. Propellants are fed via a single shaft, dual impeller turbo-pump.
Kestrel is a LOX/RP-1 pressure-fed rocket engine, and was used as the Falcon 1 rocket's second stage main engine. It is built around the same pintle architecture as SpaceX's Merlin engine but does not have a turbo-pump, and is fed only by tank pressure. Its nozzle is ablatively cooled in the chamber and throat, is also radiatively cooled, and is fabricated from a high strength niobium alloy.
Both names for the Merlin and Kestrel engines are derived from species of North American falcons: the kestrel and the merlin.[96]
Draco are hypergolic liquid-propellant rocket engines that utilize monomethyl hydrazine fuel and nitrogen tetroxide oxidizer. Each Draco thruster generates 400 newtons (90 lbf) of thrust.[97] They are used as reaction control system (RCS) thrusters on the Dragon spacecraft.[98] SuperDraco engines are a much more powerful version of the Draco thrusters, which will be initially used as landing and launch escape system engines on the version 2 Dragon spacecraft, Dragon 2.
Raptor is a new family of methane-fueled full flow staged combustion cycle engines to be used in its future Interplanetary Transport System. Development versions have been test fired.[99]
Falcon launch vehicles

From left to right, Falcon 1, Falcon 9 v1.0, three versions of Falcon 9 v1.1, three versions of Falcon 9 v1.2 (Full Thrust), two versions of Falcon 9 Block 5, and Falcon Heavy.
Falcon 9 is an EELV-class medium-lift vehicle capable of delivering up to 22,800 kilograms (50,265 lb) to orbit, and is intended to compete with the Delta IV and the Atlas V rockets, as well as other launch providers around the world. It has nine Merlin engines in its first stage.[102] The Falcon 9 v1.0 rocket successfully reached orbit on its first attempt on June 4, 2010. Its third flight, COTS Demo Flight 2, launched on May 22, 2012, and was the first commercial spacecraft to reach and dock with the International Space Station.[103] The vehicle was upgraded to Falcon 9 v1.1 in 2013 and again in 2015 to the current Falcon 9 Full Thrust version. As of February 2018, Falcon 9 vehicles have flown 49 successful missions with one failure, the CRS-7 mission. An additional vehicle was destroyed during a routine test several days prior to a scheduled launch in 2016.
In 2011, SpaceX began development of the Falcon Heavy, a heavy-lift rocket configured using a cluster of three Falcon 9 first stage cores with a total 27 Merlin 1D engines and propellant crossfeed.[104][105] The Falcon Heavy successfully flew on its inaugural mission on February 6, 2018 with a payload consisting of Musk's personal Tesla Roadster into heliocentric orbit[106] The Falcon Heavy is the world's most powerful rocket in operation.[107] The first stage would be capable of lifting 63,800 kilograms (140,660 lb) to LEO with the 27 Merlin 1D engines producing 22,819 kN of thrust at sea level, and 24,681 kN in space.
Dragon capsules
The Dragon spacecraft approaching the ISS
In 2006, NASA announced that the company was one of two selected to provide crew and cargo resupply demonstration contracts to the ISS under the COTS program.[110] SpaceX demonstrated cargo resupply and eventually crew transportation services using the Dragon.[103] The first flight of a Dragon structural test article took place in June 2010, from Launch Complex 40 at Cape Canaveral Air Force Station during the maiden flight of the Falcon 9 launch vehicle; the mock-up Dragon lacked avionics, heat shield, and other key elements normally required of a fully operational spacecraft but contained all the necessary characteristics to validate the flight performance of the launch vehicle.[111] An operational Dragon spacecraft was launched in December 2010 aboard COTS Demo Flight 1, the Falcon 9's second flight, and safely returned to Earth after two orbits, completing all its mission objectives.[93] In 2012, Dragon became the first commercial spacecraft to deliver cargo to the International Space Station,[103] and has since been conducting regular resupply services to the ISS.[112]
The interior of the COTS 2 Dragon
SpaceX plans to launch its Dragon 2 spacecraft on an uncrewed test flight to the ISS in November 2018, and in April 2019, a crewed Dragon will send US astronauts to the ISS for the first time since the retirement of the Space Shuttle.[115][116] In February 2017 SpaceX announced that two would-be space tourists had put down "significant deposits" for a mission which would see the two private astronauts fly on board a Dragon capsule around the moon and back again.
In addition to SpaceX's privately funded plans for an eventual Mars mission, NASA Ames Research Center had developed a concept called Red Dragon: a low-cost Mars mission that would use Falcon Heavy as the launch vehicle and trans-Martian injection vehicle, and the Dragon capsule to enter the Martian atmosphere. The concept was originally envisioned for launch in 2018 as a NASA Discovery mission, then alternatively for 2022[117] The objectives of the mission would be return the samples from Mars to Earth at a fraction of the cost of the NASA own return-sample mission now projected at 6 billion dollars.[117] [118]
In September 2017, Elon Musk released first prototype images of their space suits to be used in future missions. The suit is in testing phase and it is designed to cope with 2 ATM pressure in vacuum.[119][120]
Research and development
First test firing of a scale Raptor development engine in September 2016 in McGregor, Texas.
SpaceX has on occasion developed new engineering development technologies to enable it to pursue its various goals. For example, at the 2015 GPU Technology Conference, SpaceX revealed their own computational fluid dynamics (CFD) software to improve the simulation capability of evaluating rocket engine combustion design.[121][122]
Reusable launch system

SpaceX's active test program began in late 2012 with testing low-altitude, low-speed aspects of the landing technology. Grasshopper and the Falcon 9 Reusable Development Vehicles (F9R Dev) were experimental technology-demonstrator reusable rockets that performed vertical takeoffs and landings.
High-velocity, high-altitude aspects of the booster atmospheric return technology began testing in late 2013 and have continued through 2018, with a 98% success rate to date. As a result of Elon Musk's goal of crafting more cost-effective launch vehicles, SpaceX conceived a method to reuse the first stage of their primary rocket, the Falcon 9,[124] by attempting propulsive vertical landings on solid surfaces. Once the company determined that soft landings were feasible by touching down over the Atlantic and Pacific Ocean, they began landing attempts on a solid platform. SpaceX leased and modified several barges to sit out at sea as a target for the returning first stage, converting them to autonomous spaceport drone ships (ASDS). SpaceX first achieved a successful landing and recovery of a first stage in December 2015,[125] and in April 2016, the first stage booster first successfully landed on the ASDS Of Course I Still Love You.[126][127]
SpaceX continues to carry out first stage landings on every orbital launch that fuel margins allow. By October 2016, following the successful landings, SpaceX indicated they were offering their customers a ten percent price discount if they choose to fly their payload on a reused Falcon 9 first stage.[128] On March 30, 2017, SpaceX launched a "flight-proven" Falcon 9 for the SES-10 mission. This was the first time a re-launch of a payload-carrying orbital rocket went back to space.[129][65] The first stage was recovered and landed on the ASDS Of Course I Still Love You in the Atlantic Ocean, also making it the first landing of a reused orbital class rocket. Elon Musk called the achievement an "incredible milestone in the history of space."[130][131]
Interplanetary Transport System / BFR

SpaceX initially envisioned the ITS vehicle design which was solely aimed at Mars transit and other interplanetary uses, SpaceX in 2017 began to focus on a vehicle support all SpaceX launch service provider capabilities: Earth-orbit, lunar-orbit, interplanetary missions, and even intercontinental passenger transport on Earth.[132] The BFR will be the world’s most powerful rocket.[45]
Musk's long term vision for the company is the development of technology and resources suitable for human colonization on Mars. He has expressed his interest in someday traveling to the planet, stating "I'd like to die on Mars, just not on impact."[133] A rocket every two years or so could provide a base for the people arriving in 2025 after a launch in 2024.[134][135] According to Steve Jurvetson, Musk believes that by 2035 at the latest, there will be thousands of rockets flying a million people to Mars, in order to enable a self-sustaining human colony.[136]
Other projects
In January 2015, SpaceX CEO Elon Musk announced the development of a new satellite constellation to provide global broadband internet service. In June 2015 the company asked the federal government for permission to begin testing for a project that aims to build a constellation of 4,425 satellites capable of beaming the Internet to the entire globe, including remote regions which currently do not have Internet access.[137][138] The Internet service would use a constellation of 4,425 cross-linked communications satellites in 1,100 km orbits. Owned and operated by SpaceX, the goal of the business is to increase profitability and cashflow, to allow SpaceX to build its Mars colony.[139] Development began in 2015, initial prototype test-flight satellites were launched on the SpaceX PAZ mission in 2017. Initial operation of the constellation could begin as early as 2020. As of March 2017, SpaceX filed with the US regulatory authorities plans to field a constellation of an additional 7,518 "V-band satellites in non-geosynchronous orbits to provide communications services" in an electromagnetic spectrum that had not previously been "heavily employed for commercial communications services". Called the "V-band low-Earth-orbit (VLEO) constellation", it would consist of "7,518 satellites to follow the [earlier] proposed 4,425 satellites that would function in Ka- and Ku-band".[140]In June 2015, SpaceX announced that they would sponsor a Hyperloop competition, and would build a 1-mile-long (1.6 km) subscale test track near SpaceX's headquarters for the competitive events.[141][142] The first competitive event was held at the track in January 2017 and the second in August 2017.[143][144] A third event is planned for late 2018.[145]

The area has one of the largest concentrations of aerospace headquarters, facilities, and/or subsidiaries in the U.S., including Boeing/McDonnell Douglas main satellite building campuses, Aerospace Corp., Raytheon, NASA's Jet Propulsion Laboratory, Air Force Space Command's Space and Missile Systems Center at Los Angeles Air Force Base, Lockheed Martin, BAE Systems, Northrop Grumman, and AECOM, etc., with a large pool of aerospace engineers and recent college engineering graduates.[146]
SpaceX utilizes a high degree of vertical integration in the production of its rockets and rocket engines.[30] SpaceX builds its rocket engines, rocket stages, spacecraft, principal avionics and all software in-house in their Hawthorne facility, which is unusual for the aerospace industry. Nevertheless, SpaceX still has over 3,000 suppliers with some 1,100 of those delivering to SpaceX nearly weekly.[149]
In June 2017, SpaceX announced they would construct a facility on 0.88 hectares (2.17 acres) in Port Canaveral Florida for refurbishment and storage of previously-flown Falcon 9 and Falcon Heavy booster cores.[150][needs update]
Development and test facility
SpaceX McGregor engine test bunker, September 2012
The company purchased the McGregor facilities from Beal Aerospace, where it refitted the largest test stand for Falcon 9 engine testing. SpaceX has made a number of improvements to the facility since purchase, and has also extended the acreage by purchasing several pieces of adjacent farmland. In 2011, the company announced plans to upgrade the facility for launch testing a VTVL rocket,[50] and then constructed a half-acre concrete launch facility in 2012 to support the Grasshopper test flight program.[51] As of October 2012, the McGregor facility had seven test stands that are operated "18 hours a day, six days a week"[151] and is building more test stands because production is ramping up and the company has a large manifest in the next several years. [needs update]
In addition to routine testing, Dragon capsules (following recovery after an orbital mission), are shipped to McGregor for de-fueling, cleanup, and refurbishment for reuse in future missions.
Launch facilities

Cape Canaveral Air Force Station Space Launch Complex 40 (SLC-40) is used for Falcon 9 launches to low Earth and geostationary orbits. SLC-40 is not capable of supporting Falcon Heavy launches. As part of SpaceX's booster reusability program, the former Launch Complex 13 at Cape Canaveral, now renamed Landing Zone 1, has been designated for use for Falcon 9 first-stage booster landings.

Vandenberg Air Force Base Space Launch Complex 4 East (SLC-4E) is used for payloads to polar orbits. The Vandenberg site can launch both Falcon 9 and Falcon Heavy,[154] but cannot launch to low inclination orbits. Post-launch landings will take place at the neighboring SLC-4W.Kennedy Space Center
On April 14, 2014, SpaceX signed a 20-year lease for Launch Pad 39A.[155] The pad was subsequently modified to support Falcon 9 and Falcon Heavy launches. SpaceX has launched 13 Falcon 9 missions from Launch Pad 39A and more recently the Falcon Heavy, on February 6, 2018. SpaceX intends to launch the first crewed missions to the ISS from Launch Pad 39A in December 2018.[156]Brownsville
In August 2014, SpaceX announced they would be building a commercial-only launch facility at Brownsville, Texas.[157][158] The Federal Aviation Administration released a draft Environmental Impact Statement for the proposed Texas facility in April 2013, and "found that 'no impacts would occur' that would force the Federal Aviation Administration to deny SpaceX a permit for rocket operations,"[159][159] and issued the permit in July 2014.[160] SpaceX started construction on the new launch facility in 2014 with production ramping up in the latter half of 2015,[161] with the first launches from the facility no earlier than late 2018.[162] Real estate packages at the location have been named by SpaceX with names based on the theme "Mars Crossing".[163][164]Satellite prototyping facility
In January 2015, SpaceX announced it would be entering the satellite production business and global satellite internet business. The first satellite facility is a 30,000 square foot (2800m2) office building located in Redmond, Washington. As of January 2017, a second facility in Redmond was acquired with 40,625 square feet (3800m2) and has become a research and development lab for the satellites.[165] In July 2016, SpaceX acquired an additional 740 square meters (8,000 sq ft) creative space in Irvine, California (Orange County) to focus on satellite communications.[166]Launch contracts
SpaceX won demonstration and actual supply contracts from NASA for the International Space Station (ISS) with technology the company developed. SpaceX is also certified for US military launches of Evolved Expendable Launch Vehicle-class (EELV) payloads. With approximately 30 missions on manifest for 2018 alone, SpaceX represents over $12B under contract.[45]NASA contracts
COTS
The COTS 2 Dragon is berthed to the ISS by Canadarm2.
In December 2010, the launch of the COTS Demo Flight 1 mission, SpaceX became the first private company to successfully launch, orbit and recover a spacecraft.[170] Dragon was successfully deployed into orbit, circled the Earth twice, and then made a controlled re-entry burn for a splashdown in the Pacific Ocean. With Dragon's safe recovery, SpaceX became the first private company to launch, orbit, and recover a spacecraft; prior to this mission, only government agencies had been able to recover orbital spacecraft.
COTS Demo Flight 2 launched in May 2012, in which Dragon successfully berthed with the ISS, marking the first time that a private spacecraft had accomplished this feat.[171][172]
Commercial cargo
Commercial Resupply Services (CRS) are a series of contracts awarded by NASA from 2008–2016 for delivery of cargo and supplies to the ISS on commercially operated spacecraft. The first CRS contracts were signed in 2008 and awarded $1.6 billion to SpaceX for 12 cargo transport missions, covering deliveries to 2016.[173] SpaceX CRS-1, the first of the 12 planned resupply missions, launched in October 2012, achieved orbit, berthed and remained on station for 20 days, before re-entering the atmosphere and splashing down in the Pacific Ocean.[174] CRS missions have flown approximately twice a year to the ISS since then. In 2015, NASA extended the Phase 1 contracts by ordering an additional three resupply flights from SpaceX.[175][176] After further extensions late in 2015, SpaceX is currently scheduled to fly a total of 20 missions.[177] A second phase of contracts (known as CRS2) were solicited and proposed in 2014. They were awarded in January 2016, for cargo transport flights beginning in 2019 and expected to last through 2024.Commercial crew
Crew Dragon undergoing testing prior to flight
In September 2014, NASA chose SpaceX and Boeing as the two companies that will be funded to develop systems to transport U.S. crews to and from the ISS. SpaceX won $2.6 billion to complete and certify Dragon 2 by 2017. The contracts include at least one crewed flight test with at least one NASA astronaut aboard. Once Crew Dragon achieves NASA certification, the contract requires SpaceX to conduct at least two, and as many as six, crewed missions to the space station.[183] In early 2017, SpaceX was awarded four additional crewed missions to the ISS from NASA to shuttle astronauts back and forth.[184]
US Defense contracts
In 2005, SpaceX announced that it had been awarded an Indefinite Delivery/Indefinite Quantity (IDIQ) contract for Responsive Small Spacelift (RSS) launch services by the United States Air Force, which could allow the Air Force to purchase up to $100 million worth of launches from the company.[185] In April 2008, NASA announced that it had awarded an IDIQ Launch Services contract to SpaceX for up to $1 billion, depending on the number of missions awarded. The contract covers launch services ordered by June 2010, for launches through December 2012.[186] Musk stated in the same 2008 announcement that SpaceX has sold 14 contracts for flights on the various Falcon vehicles.[186] In December 2012, SpaceX announced its first two launch contracts with the United States Department of Defense. The United States Air Force Space and Missile Systems Center awarded SpaceX two EELV-class missions: Deep Space Climate Observatory (DSCOVR) and Space Test Program 2 (STP-2). DSCOVR was launched on a Falcon 9 launch vehicle in 2015, while STP-2 will be launched on a Falcon Heavy in 2018.[187]In May 2015, the United States Air Force announced that the Falcon 9 v1.1 was certified for launching "national security space missions," which allows SpaceX to contract launch services to the Air Force for any payloads classified under national security.[188] This broke the monopoly held since 2006 by ULA over the US Air Force launches of classified payloads.[189]
In April 2016, the U.S. Air Force awarded the first such national security launch, an $82.7 million contract to SpaceX to launch the 2nd GPS III satellite in May 2018; this estimated cost was approximately 40% less than the estimated cost for similar previous missions.[190][191][192] Prior to this, United Launch Alliance was the only provider certified to launch national security payloads.[193][193][194] ULA did not submit a bid for the May 2018 launch.[195][196]
In 2016 the US National Reconnaissance Office said it had purchased launches from SpaceX - the first (for NROL-76) took place on 1st May 2017.[197]
In March 2017 SpaceX won (vs ULA) with a bid of $96.5 million for the 3rd GPS III launch (due Feb 2019).[198]
In March 2018, SpaceX secured an additional $290 million contract from the U.S. Air Force to launch three next generation GPS satellites, known as GPS III. The first of these launches is expected to take place in March 2020.[199]
Launch market competition and pricing pressure
SpaceX's low launch prices, especially for communication satellites flying to geostationary (GTO) orbit, have resulted in market pressure on its competitors to lower their own prices.[30] Prior to 2013, the openly competed comsat launch market had been dominated by Arianespace (flying Ariane 5) and International Launch Services (flying Proton).[200] With a published price of US$56.5 million per launch to low Earth orbit, "Falcon 9 rockets [were] already the cheapest in the industry. Reusable Falcon 9s could drop the price by an order of magnitude, sparking more space-based enterprise, which in turn would drop the cost of access to space still further through economies of scale."[201] SpaceX has publicly indicated that if they are successful with developing the reusable technology, launch prices in the US$5 to 7 million range for the reusable Falcon 9 are possible.[202]In 2014, SpaceX had won nine contracts out of 20 that were openly competed worldwide in 2014 at commercial launch service providers.[203] Space media reported that SpaceX had "already begun to take market share" from Arianespace.[204] Arianespace has requested that European governments provide additional subsidies to face the competition from SpaceX.[205][206] European satellite operators are pushing the ESA to reduce Ariane 5 and the future Ariane 6 rocket launch prices as a result of competition from SpaceX. According to one Arianespace managing director in 2015, it was clear that "a very significant challenge [was] coming from SpaceX ... Therefore things have to change ... and the whole European industry is being restructured, consolidated, rationalised and streamlined."[207] Jean Botti, Director of innovation for Airbus (which makes the Ariane 5) warned that "those who don't take Elon Musk seriously will have a lot to worry about."[208] In 2014, no commercial launches were booked to fly on the Russian Proton rocket.[203]
Also in 2014, SpaceX capabilities and pricing began to affect the market for launch of US military payloads. For nearly a decade the large US launch provider United Launch Alliance (ULA) had faced no competition for military launches.[209] Without this competition, launch costs by the U.S. provider rose to over $400 million.[210] The ULA monopoly ended when SpaceX began to compete for national security launches. At a side-by-side comparison, SpaceX’s launch costs for commercial missions are considerably lower at $62 million.[211]
In 2015, anticipating a slump in domestic military and spy launches, ULA stated that it would go out of business unless it won commercial satellite launch orders.[212] To that end, ULA announced a major restructuring of processes and workforce in order to decrease launch costs by half.[213][214]
In 2017, SpaceX had 45% global market share for awarded commercial launch contracts, the estimate for 2018 is about 65% as of July 2018.[215]
