99-688: Started in 1994 as the Evolved Expendable Launch Vehicle launch system program, the initial program goal was to make government space launches more affordable and reliable , leading to the development of the Boeing Delta IV and Lockheed Martin Atlas V EELV families. These remained the primary launch vehicles for U.S. military satellites , and were later joined by the Falcon 9 developed by SpaceX . On 1 March 2019,

198-803: A 5 m payload fairing. Delta IV CBCs and DCSSs were integrated horizontally before being transported to the launchpad. In 2020, ULA announced retirement of the Delta IV after 5 more launches. The final flight occurred in April 2024. Each Atlas V launch vehicle is based on a Common Core Booster powered by one NPO Energomash RD-180 engine with two combustion chambers and a Centaur upper stage powered by one or two Pratt & Whitney Rocketdyne RL10A-4-2 engines. Up to five Aerojet Rocketdyne Graphite-Epoxy Motor solid rocket boosters can be added to increase vehicle performance, and two diameters of payload fairing are available. A three-digit naming convention

297-560: A Falcon Heavy launch vehicle using three Falcon 1 core boosters, with an approximate payload-to-LEO capacity of two tons, were initially discussed as early as 2003. The concept for three core booster stages of the company's as-yet-unflown Falcon 9 was referred to in 2005 as the Falcon 9 Heavy . SpaceX unveiled the plan for the Falcon Heavy to the public at a Washington, D.C. , news conference in April 2011, with an initial test flight expected in 2013. A number of factors delayed

396-465: A competitive contract award to launch national security spacecraft was conducted between United Launch Alliance (ULA), Northrop Grumman Innovation Systems (NGIS), Blue Origin , and SpaceX. Two providers were to be selected to launch spacecraft to a number of reference orbits. In October 2018, the USAF awarded development funding to ULA, NGIS, and Blue Origin to further the design of their rockets before

495-438: A complex launch vehicle like the three-core Falcon Heavy, indicating that a large extent of the new design "is really impossible to test on the ground" and could not be effectively tested independent of actual flight tests . By September 2017, all three first stage cores had completed their static fire tests on the ground test stand. The first Falcon Heavy static fire test was conducted on 24 January 2018. In April 2011, Musk

594-559: A contract under the EELV program to launch a GPS Block III satellite payload to MEO . The USAF began the process of competitively selecting the next generation NSSL vehicles in 2018. Announced performance requirements include: Category A payloads fit within a 4 m diameter payload envelope , category B payloads fit within a 5 m diameter payload envelope, and category C payloads require an extended 5 m diameter envelope. The USAF and United States Space Force (USSF) plan to use

693-488: A couple of years". Speaking at the 2008 Mars Society Conference, Musk also indicated that he expected a hydrogen-fueled upper stage would follow two to three years later (which would have been around 2013). By April 2011, the capabilities and performance of the Falcon 9 vehicle were better understood, SpaceX having completed two successful demonstration missions to low Earth orbit (LEO), one of which included reignition of

792-413: A draft RFP for "Phase 3" of NSSL, which covers the five fiscal years 2025-2029. Unlike the earlier NSSL contracts, Phase 3 is divided into two "lanes". Lane 1 covers less demanding missions and is structured to encourage new launch providers. Lane 2 is more similar to Phase 2 and requires each provider to be able to handle all NSSL requirements. However, Lane 2 allows for up to three providers instead of just

891-483: A few minutes later. However, only one of the three engines on the center booster that were intended to restart ignited during descent, causing the booster to be destroyed upon impacting the ocean at a speed of over 480 km/h (300 mph). Initially, Elon Musk tweeted that the Roadster had overshot its planned heliocentric orbit , and would reach the asteroid belt . Later, observations by telescopes showed that

990-644: A first launch of New Glenn in 2021. In the event, no phase 2 funding from the US government was forthcoming after August 2020 when ULA Vulcan and SpaceX were selected by the Air Force. Blue Origin is considered likely to continue building and testing New Glenn, in part since they were already privately funding development prior to the Air Force NSSL competition. Northrop Grumman was awarded US$ 792 million of phase 1 funding in 2018 for development of OmegA. OmegA

1089-601: A new, partly underground test stand was being built at the SpaceX Rocket Development and Test Facility in McGregor, Texas , specifically to test the triple cores and twenty-seven rocket engines of the Falcon Heavy. By May 2017, SpaceX conducted the first static fire test of flight-design Falcon Heavy center core at the McGregor facility. In July 2017, Musk discussed publicly the challenges of testing

1188-613: A price of US$ 2,350 per kg to LEO and US$ 5,620 per kg to GTO. In 2022, the published price for a reusable launch was $ 97 million. In 2022 NASA contracted with SpaceX to launch the Nancy Grace Roman Space Telescope on a Falcon Heavy for approximately $ 255 million, including launch service and other mission related costs. The nearest competing U.S. rocket was ULA's Delta IV Heavy with a LEO payload capacity of 28.4 t (63,000 lb) costs US$ 12,340 per kg to LEO and US$ 24,630 per kg to GTO. The Delta IV Heavy

1287-540: A rocket stage may be recovered while others are not. The Space Shuttle , for example, recovered and reused its solid rocket boosters , the Space Shuttle orbiter that also acted as a second stage, and the engines used by the core stage (the RS-25 , which was located at the back of the orbiter), however the fuel tank that the engines sourced fuel from, which was separate from the engines, was not reused. For example,

1386-512: A second stage on top of the center core. Falcon Heavy has the second highest payload capacity of any currently operational launch vehicle behind NASA 's Space Launch System (SLS), and the fourth-highest capacity of any rocket to reach orbit, trailing behind the SLS , Energia and the Saturn V . SpaceX conducted Falcon Heavy's maiden launch on 6 February 2018, at 20:45 UTC . As a dummy payload ,

1485-399: A subsequent competition for award to build the launch vehicles. SpaceX received none of this funding to develop their designs, as both the Falcon 9 and Falcon Heavy had completed development and were already flying. Blue Origin was awarded $ 500 million of phase 1 funding for further development of New Glenn as a potential competitor in future contracts. As of 2019, Blue Origin expected

1584-426: A total sea-level thrust at liftoff of 22.82 MN (5,130,000 lbf), from the 27 Merlin 1D engines, while thrust rises to 24.68 MN (5,550,000 lbf) as the craft climbs out of the atmosphere. The upper stage is powered by a single Merlin 1D engine modified for vacuum operation, with a thrust of 934 kN (210,000 lbf), an expansion ratio of 117:1 and a nominal burn time of 397 seconds. At launch,

1683-638: Is 35% of the cost of the lowest-cost-per-pound LEO -capable launch system in a 2001 study: the Zenit , a medium-lift launch vehicle that could carry 14 t (31,000 lb) into LEO for US$ 35–50 million. In 2011, SpaceX stated that the cost of reaching low Earth orbit could be as low as $ 2,200/kg ($ 1,000/lb) if an annual rate of four launches can be sustained, and as of 2011 planned to eventually launch as many as 10 Falcon Heavies and 10 Falcon 9s annually. The published prices for Falcon Heavy launches have changed as development progressed, with announced prices for

1782-517: Is a carbon fiber aluminum core composite structure. Stage separation occurs via reusable separation collets and a pneumatic pusher system. The Falcon 9 tank walls and domes are made from Aluminum–lithium alloy . SpaceX uses an all- friction stir welded tank. The second stage tank of Falcon 9 is simply a shorter version of the first stage tank and uses most of the same tooling, material, and manufacturing techniques. This approach reduces manufacturing costs during vehicle production. All three cores of

1881-594: Is a super heavy-lift rocket developed and produced by SpaceX. It has been certified for the NSSL program after the STP-2 launch completed on 25 June 2019, as confirmed by the commander of the Air Force Space and Missile Systems Center, Lt. Gen. Thompson. He clarified: "I certified them to compete last year" and "one of the requirements behind certification is to fly three missions." This requirement has been satisfied by

1980-595: Is developing the first stage of the orbital New Glenn LV to be reusable, with first flight planned for no earlier than 2024. SpaceX has a new super-heavy launch vehicle under development for missions to interplanetary space . The SpaceX Starship is designed to support RTLS, vertical-landing and full reuse of both the booster stage and the integrated second-stage/large-spacecraft that are designed for use with Starship. Its first launch attempt took place in April 2023; however, both stages were lost during ascent. The fifth launch attempt ended with Booster 12 being caught by

2079-452: Is reduced by the reusable technology, but at a much lower price. When recovering all three booster cores, GTO payload is 8 t (18,000 lb). If only the two outside cores are recovered while the center core is expended, GTO payload would be approximately 16 t (35,000 lb). As a comparison, the next-heaviest contemporary rocket, the fully expendable Delta IV Heavy, could deliver 14.2 t (31,000 lb) to GTO. Falcon Heavy

2178-463: 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. An orbital launch vehicle must lift its payload at least to

2277-746: Is used for the Atlas V configuration identification. The first digit represents the payload fairing diameter, either 4.2 meters (indicated by a 4) or 5.4 (indicated by a 5) meters. The second digit is for the number of solid rocket boosters (0 to 5) to be used, and the third digit the number of RL-10 engines on the Centaur upper stage (1 or 2). As an example, an Atlas V 551 has a 5.4-meter payload fairing, 5 SRBs, and 1 RL-10. In August 2021, ULA announced that Atlas V would be retired, and all 29 remaining launches had been sold. The last launch for NSSL happened on 30 July 2024. As of July 2024, fifteen launches remain, all for non-DoD launches. The main features of

2376-451: The Atlas V Heavy and Russian Angara A5V . This triple first stage carries a standard Falcon 9 second stage, which in turn carries the payload in a fairing. Falcon Heavy has the second highest lift capability of any operational rocket, with a payload of 63,800 kg (140,700 lb) to low Earth orbit, 26,700 kg (58,900 lb) to Geostationary Transfer Orbit , and 16,800 kg (37,000 lb) to trans-Mars injection . The rocket

2475-629: The Delta IV based around Common Booster Cores and the Delta Cryogenic Second Stage , while Lockheed Martin developed the Atlas V based around Common Core Boosters and the Centaur upper stage. In 2003, Boeing was found to be in possession of proprietary documents from Lockheed Martin. The USAF moved 7 launches from Delta IV to Atlas V. To end litigation and competition for a limited market, both companies agreed to form

2574-640: The European Space Agency is responsible for the Ariane V , and the United Launch Alliance manufactures and launches the Delta IV and Atlas V rockets. Launchpads can be located on land ( spaceport ), on a fixed ocean platform ( San Marco ), on a mobile ocean platform ( Sea Launch ), and on a submarine . Launch vehicles can also be launched from the air . A launch vehicle will start off with its payload at some location on

2673-471: The Falcon 9 first stage , and have successfully recovered multiple payload fairings . In the case of Falcon Heavy, the two outer cores separate from the rocket earlier in the flight, and are thus moving at a lower velocity than in a Falcon 9 launch profile. For the first flight of Falcon Heavy, SpaceX had considered attempting to recover the second stage, but did not execute this plan. Falcon Heavy payload performance to geosynchronous transfer orbit (GTO)

2772-502: The Falcon 9 vehicle family since the 2012 announcement, advertising 8.3 t (18,000 lb) to GTO for its expendable flight profile, enabled the launch of this 6 t satellite without upgrading to a Falcon Heavy variant. In 2014, Inmarsat booked three launches with Falcon Heavy, but due to delays, switched a payload to Ariane 5 for 2017. Similarly to the Intelsat 35e case, another satellite from this contract, Inmarsat 5-F4 ,

2871-703: The Falcon Heavy test flight in February 2018, Arabsat-6A in April 2019, and the STP-2 launch in June 2019. Falcon Heavy has been certified for two Phase 1A reference orbits and as of 2019, "it's not certified for all of our most stressing national security space orbits," Thompson said. The USAF is working with SpaceX to mature their Falcon Heavy's design. As of December 2023, it has flown three classified national security flights: USSF-44, USSF-67, and USSF-52. In 2018,

2970-537: The U.S. Space Force certified Falcon Heavy for launching its top secret satellites, with the first such launch being USSF-44 which happened at 1 November 2022; and the second of which being USSF-67, which was launched 11 weeks after USSF-44. ViaSat selected the Falcon Heavy in late 2018 for the launch of its ViaSat-3 satellite which was scheduled to launch in the 2020–2022 timeframe; however it would not launch until 1 May 2023. On 13 October 2023, Falcon Heavy embarked on its 8th flight carrying NASA's Psyche probe to

3069-459: The U.S. government shutdown that began on 20 January 2018 , the testing and launch were further delayed. The static fire test was conducted on 24 January 2018. Musk confirmed via Twitter that the test "was good" and later announced the rocket would be launched on 6 February 2018. On 6 February 2018, after a delay of over two hours due to high winds, Falcon Heavy lifted off at 20:45 UTC. Its side boosters landed safely on Landing Zones 1 and 2

3168-741: The United Launch Alliance (ULA) joint venture. Each company has a 50% stake in ULA. Prior to 2012, the USAF was advancing another program, the Reusable Booster System and other follow-on technologies, and up to early 2012 issued contract awards for various aspects of it, before the program was cancelled in October 2012. In December 2012, the DoD announced a re-opening of the EELV-class launch vehicle market to competition while authorizing

3267-519: The United States Senate Committee on Commerce, Science, and Transportation , Musk testified, "Long term plans call for development of a heavy lift product and even a super-heavy, if there is customer demand. We expect that each size increase would result in a meaningful decrease in cost per pound to orbit. ... Ultimately, I believe US$ 500 per pound or less is very achievable". This $ 1,100/kg ($ 500/lb) goal stated by Musk in 2011

3366-444: The upper stage of the launch vehicle or launched to a geostationary transfer orbit (GTO). A direct insertion places greater demands on the launch vehicle, while GTO is more demanding of the spacecraft. Once in orbit, launch vehicle upper stages and satellites can have overlapping capabilities, although upper stages tend to have orbital lifetimes measured in hours or days while spacecraft can last decades. Distributed launch involves

3465-472: The 2000s and launch vehicles with integrated distributed launch capability built in began development in 2017 with the Starship design. The standard Starship launch architecture is to refuel the spacecraft in low Earth orbit to enable the craft to send high-mass payloads on much more energetic missions. After 1980, but before the 2010s, two orbital launch vehicles developed the capability to return to

3564-537: The Artemis Program's Commercial Lunar Payload Services (CLPS) initiative. On October 14, 2024, Falcon Heavy transported NASA's Europa Clipper into space to explore Jupiter's moon Europa. Falcon Heavy consists of a structurally strengthened Falcon 9 as the "core" component, with two additional Falcon 9 first stages with aerodynamic nose-cones mounted outboard serving as strap-on boosters , conceptually similar to Delta IV Heavy launcher and proposals for

3663-452: The EELV program in 1994, following many years of government-funded studies into improved systems and architecture. The intent was to replace legacy vehicles, including Delta II , Atlas II , and Titan IV . EELVs were to reduce costs by being based on standardized fairings, liquid core vehicles , upper stages, and solid rocket boosters . A Standard Payload Interface bus was also proposed as a way to save money and improve efficiency. Reducing

3762-416: The Falcon 9 in its Block 5 version include two stages , both powered by LOX and RP-1 , with nine Merlin 1D engines on the first stage and one Merlin 1D Vacuum engine on the second stage. This launcher features a reusable first stage and fairings, which lowers the cost per mission. GPS-IIIA USA-289 was the first NSSL-type B5 Falcon 9 launch. The launch occurred on December 23, 2018. The Falcon Heavy

3861-406: The Falcon Heavy arrange the engines in a structural form SpaceX calls Octaweb , aimed at streamlining the manufacturing process, and each core includes four extensible landing legs. To control the descent of the boosters and center core through the atmosphere, SpaceX uses four retractable grid fins at the top of each of the three Falcon 9 boosters, which extend after separation. Immediately after

3960-889: The Orion capsule. However, Falcon Heavy will support commercial missions for the Artemis program, since it will be used to transport the Dragon XL spacecraft to the Lunar Gateway . It was also selected to launch the first two elements of the Lunar Gateway, the Power and Propulsion Element (PPE), and the Habitation and Logistics Outpost (HALO), on a single launch no earlier than 2025, and to launch NASA's VIPER rover aboard Astrobotic Technology 's Griffin lander as part of

4059-406: The Roadster would only slightly exceed the orbit of Mars at aphelion . A year after the successful demo flight, SpaceX had signed five commercial contracts worth US$ 500–750 million, meaning that it had managed to cover the development cost of the rocket. The second flight, and first commercial one, occurred on 11 April 2019, launching Arabsat-6A , with all three boosters landing successfully for

4158-429: The USAF to proceed with a block buy of "up to" 36 boosters from ULA. At the same time, another 14 boosters were to be procured competitively beginning in 2015, with the initial launches to be performed in 2017. The USAF signed a contract at that time with SpaceX for two launches in 2014 and 2015 to serve as proving flights to support the certification process for the Falcon 9 v1.1 and Falcon Heavy . In April 2014, after

4257-594: The USSF selected SpaceX (F9 and FH) and ULA's yet-to-be-certified Vulcan Centaur to supply US military launch requirements in 2022–2027. New Glenn was considered for the first time in NSSL Phase 3 Lane 1 bidding. Delta IV Medium flew with two or four SRBs on a single Common Booster Core . The DCSS had 4 m diameter and 5 m diameter versions, with matching diameter payload fairings. Delta IV CBCs and DCSSs were integrated horizontally before being transported to

4356-548: The accomplishment of a goal with multiple spacecraft launches. A large spacecraft such as the International Space Station can be constructed by assembling modules in orbit, or in-space propellant transfer conducted to greatly increase the delta-V capabilities of a cislunar or deep space vehicle. Distributed launch enables space missions that are not possible with single launch architectures. Mission architectures for distributed launch were explored in

4455-498: The asteroid 16 Psyche . This mission only had the side boosters return to Earth with the center core expended, a decision made to create more tolerable margins for the mission. Following the announcement of NASA's Artemis program of returning humans to the Moon, the Falcon Heavy rocket has been mentioned several times as an alternative to the expensive Space Launch System (SLS) program, but NASA decided to exclusively use SLS to launch

4554-400: The award of two development agreements, the total amount was more than $ 3 billion. Boeing was awarded a contract for 19 out of the 28 launches; Lockheed Martin was awarded a contract for the other 9. Boeing received $ 1.38 billion, and Lockheed Martin received $ 650 million for the launches. Boeing and Lockheed Martin were each awarded US$ 500 million for the final phase of the bid. Boeing developed

4653-487: The booster stage of a launch vehicle. After 2010, SpaceX undertook a development program to acquire the ability to bring back and vertically land a part of the Falcon 9 orbital launch vehicle: the first stage . The first successful landing was done in December 2015, since 2017 rocket stages routinely land either at a landing pad adjacent to the launch site or on a landing platform at sea, some distance away from

4752-838: The boundary of space, approximately 150 km (93 mi) and accelerate it to a horizontal velocity of at least 7,814 m/s (17,480 mph). Suborbital vehicles launch their payloads to lower velocity or are launched at elevation angles greater than horizontal. Practical orbital launch vehicles use chemical propellants such as solid fuel , liquid hydrogen , kerosene , liquid oxygen , or hypergolic propellants . Launch vehicles are classified by their orbital payload capacity, ranging from small- , medium- , heavy- to super-heavy lift . Launch vehicles are classed by NASA according to low Earth orbit payload capability: Sounding rockets are similar to small-lift launch vehicles, however they are usually even smaller and do not place payloads into orbit. A modified SS-520 sounding rocket

4851-460: The cancellation of OmegA. ULA was awarded $ 967 million of phase 1 funding for further development of Vulcan Centaur as a potential competitor in future contracts. On 12 August 2019, ULA submitted Vulcan Centaur for phase 2 of the USAF's launch services competition. As of July 2024, Vulcan Centaur has completed one certification flight launch and another is left be fully certified for national security launches. On 12 August 2019, at least three of

4950-484: The capability of producing a Falcon 9 first stage or Falcon Heavy side booster every week and an upper stage every two weeks". In 2015, SpaceX announced a number of changes to the Falcon Heavy rocket, worked in parallel to the upgrade of the Falcon 9 v1.1 launch vehicle. In December 2016, SpaceX released a photo showing the Falcon Heavy interstage at the company headquarters in Hawthorne, California . By May 2013,

5049-428: The center core throttles to full power for a few seconds for additional thrust, then throttles down. This allows a longer burn time. After the side boosters separate, the center core throttles back up to maximum thrust. For added reliability of restart, the engine has dual redundant pyrophoric igniters ( Triethylaluminium - Triethylborane ) (TEA-TEB). The interstage, which connects the upper and lower stage for Falcon 9,

5148-404: The center core touches down on a drone ship. If boosters are expended, then the landing legs and grid fins are omitted from the vehicle. The landing legs are made of carbon fiber with aluminum honeycomb structure . The four legs stow along the sides of each core during liftoff and extend outward and down just before landing. The Falcon Heavy uses a 4.5 m (15 ft) interstage attached to

5247-719: The cost of launches and ensuring national access to space were the two main goals of the USAF space launch/EELV program. Some of the reasons why assured access to space is a priority for the United States are stated in National Presidential Directive Number 40, which reads: Access to space through U.S. space transportation capabilities is essential to: The United States, therefore, must maintain robust, responsive, and resilient U.S. space transportation capabilities to assure access to space. Procurement of EELV boosters for military space launch

5346-466: The debut of Falcon Heavy. SpaceX anticipated the first commercial Falcon Heavy launch would be three to six months after a successful maiden flight, but due to delays, the first commercial payload, Arabsat-6A was successfully launched on 11 April 2019, a year and two months after the first flight. SpaceX hoped to have 10 launches every year from 2021 on, but there were no launches in 2020 or 2021. In May 2012, SpaceX announced that Intelsat had signed

5445-416: The first Falcon Heavy lifted off on 6 February 2018, at 20:45 UTC, carrying its dummy payload, Elon Musk's personal Tesla Roadster , beyond Mars orbit. Musk first mentioned Falcon Heavy in a September 2005 news update, referring to a customer request from 18 months prior. Various solutions using the planned Falcon 5 (which was never flown) had been explored, but the only cost-effective, reliable iteration

5544-435: The first commercial contract for a Falcon Heavy flight. It was not confirmed at the time when the first Intelsat launch would occur, but the agreement had SpaceX delivering satellites to geosynchronous transfer orbit (GTO). In August 2016, it emerged that this Intelsat contract had been reassigned to a Falcon 9 Full Thrust mission to deliver Intelsat 35e into orbit in the third quarter of 2017. Performance improvements of

5643-458: The first stage boosters to the launch site as well as recover the first stage core following landing at an Autonomous Spaceport Drone Ship barge after completion of primary mission requirements. These systems include four deployable landing legs , which are locked against each first-stage tank core during ascent and deploy just prior to touchdown. Excess propellant reserved for Falcon Heavy first-stage recovery operations will be diverted for use on

5742-491: The first stage core. It is a composite structure consisting of an aluminum honeycomb core surrounded by carbon fiber face sheet plies. Unlike for Falcon 9, the black thermal protection layer on the interstage of Block 5 center core boosters is later painted white, as seen in the Falcon Heavy flights so far, probably due to aesthetics of the Falcon Heavy Logo, providing it a greyish look. The overall length of

5841-457: The first time. The third flight occurred on 25 June 2019, launching the STP-2 (DoD Space Test Program) payload. The payload was composed of 25 small spacecraft. Operational Geostationary transfer orbit (GTO) missions for Intelsat and Inmarsat , which were planned for late 2017, were moved to the Falcon 9 Full Thrust rocket version as it had become powerful enough to lift those heavy payloads in its expendable configuration. In June 2022,

5940-416: The four companies submitted their final bids for the launch services competition. SpaceX bid the existing Falcon 9 and Falcon Heavy , while Blue Origin was expected to bid New Glenn, ULA bid Vulcan Centaur, and NGIS's bid status was not reported. Blue Origin also filed a pre-award protest of the request for proposal arguing that the requirements were ambiguous. The US Department of the Air Force announced

6039-442: The ground. In contrast, reusable launch vehicles are designed to be recovered intact and launched again. The Falcon 9 is an example of a reusable launch vehicle. As of 2023, all reusable launch vehicles that were ever operational have been partially reusable, meaning some components are recovered and others are not. This usually means the recovery of specific stages, usually just the first stage, but sometimes specific components of

6138-528: The launch site (RTLS). Both the US Space Shuttle —with one of its abort modes —and the Soviet Buran had a designed-in capability to return a part of the launch vehicle to the launch site via the mechanism of horizontal-landing of the spaceplane portion of the launch vehicle. In both cases, the main vehicle thrust structure and the large propellant tank were expendable , as had been

6237-505: The launch site. The Falcon Heavy is similarly designed to reuse the three cores comprising its first stage. On its first flight in February 2018, the two outer cores successfully returned to the launch site landing pads while the center core targeted the landing platform at sea but did not successfully land on it. Blue Origin developed similar technologies for bringing back and landing their suborbital New Shepard , and successfully demonstrated return in 2015, and successfully reused

6336-484: The launch tower, and Ship 30, the upper stage, successfully landing in the Indian Ocean. Falcon Heavy Falcon Heavy is a super heavy-lift launch vehicle with partial reusability that can carry cargo into Earth orbit and beyond. It is designed, manufactured and launched by American aerospace company SpaceX . The rocket consists of a center core on which two Falcon 9 boosters are attached, and

6435-461: The launches over the five-year period. The contract type for the phase 2 contracts is new for NSSL launches as it will be a "firm-fixed-price, indefinite-delivery" type of launch contract. The awards in August 2020 are a major part of "the transition of the national security launch program to take advantage of commercial innovation and private investments in launch vehicles." In 2023, USSF released

6534-799: The launches were contracted, SpaceX sued the United States Air Force, arguing that the RD-180 engines, produced in Russia by the government owned NPO Energomash and used by the Atlas V, violated sanctions against the Russian government. The USAF and SpaceX settled the lawsuit in Jan 2015 by opening up more launches to competitive bidding. The USAF certified the Falcon 9 in May 2015, and in 2016 SpaceX won

6633-451: The launchpad. The Delta IV Medium retired after the 22 August 2019 launch of a GPS-III satellite . The mission used a Delta IV M+(4,2) two SRBs, and a 4 m diameter DCSS and payload fairing, the final use of the 4 m fairing. The Delta IV Heavy launch vehicle used three Common Booster Cores (CBCs) each powered by a Pratt and Whitney Rocketdyne RS-68A engine, a Delta Cryogenic Second Stage 5 m (DCSS) powered by an RL10 , and

6732-653: The maiden Falcon Heavy flight in September 2015 to occur no earlier than April 2016. The flight was to be launched from the refurbished Kennedy Space Center Launch Complex 39A . The flight was postponed again to late 2016, early 2017, summer 2017, late 2017 and finally to February 2018. At a July 2017 meeting of the International Space Station Research and Development meeting in Washington, D.C. , Musk downplayed expectations for

6831-519: The next generation NSSL launch vehicles until at least 2030. See EELV_Secondary_Payload_Adapter (ESPA rings with radial ports) Since 2019 there have been four vehicles certified by the Department of Defense to conduct NSSL launches: Atlas V, Delta IV Heavy, Falcon 9 and Falcon Heavy. Delta IV Medium was retired in August 2019 and Delta IV Heavy retired in April 2024. After a two-year solicitation and competition process in 2018–2020, in August 2020

6930-565: The payload penalty to be around 10%, which would still yield over 57 t (126,000 lb) of lift capability to LEO. Returning all three boosters to the launch site rather than landing them on drone ships would yield about 30 t of payload to LEO. From 2013 to 2016, SpaceX conducted parallel development of a reusable rocket architecture for Falcon 9 , that applies to parts of Falcon Heavy as well. Early on, SpaceX had expressed hopes that all rocket stages would eventually be reusable . SpaceX has since demonstrated routine land and sea recovery of

7029-503: The planned maiden flight to 2018, including two anomalies with Falcon 9 launch vehicles, which required all engineering resources to be dedicated to failure analysis, halting flight operations for many months. The integration and structural challenges of combining three Falcon 9 cores were much more difficult than expected. In July 2017, Elon Musk said, "It actually ended up being way harder to do Falcon Heavy than we thought. ... We were pretty naive about that". The initial test flight for

7128-443: The primary mission objective, if required, ensuring sufficient performance margins for successful missions. The nominal payload capacity to a geostationary transfer orbit (GTO) is 8 t (18,000 lb) with recovery of all three first-stage cores (the price per launch is US$ 97 million), versus 26.7 t (59,000 lb) in fully expendable mode. The Falcon Heavy can also inject a 16 t (35,000 lb) payload into GTO if only

7227-522: The program name was changed from EELV to National Security Space Launch (NSSL) to better reflect the growing commercial launch market and the changing nature of launch contracts, including the potential for reusable launch vehicles. The NSSL program launches the nation's most valuable military satellites; contracts to launch lower value payloads, such as those of the Space Test Program , are awarded using different methodologies. The USAF began

7326-433: The projected GTO payload for Falcon Heavy to 21.2 t (47,000 lb). In April 2017, the projected LEO payload for Falcon Heavy was raised from 54.4 to 63.8 t (120,000 to 141,000 lb). The maximum payload is achieved when the rocket flies a fully expendable launch profile, not recovering any of the three first-stage boosters. With just the core booster expended, and two side-boosters recovered, Musk estimates

7425-438: The results of the approximately US$ 3.5 billion National Security Space Launch Phase 2 Launch Service Procurement on 7 August 2020. SpaceX and ULA were the two vendors selected via the competition to supply launches to the US military in the 2022–2026 timeframe. The US Space Force (USSF) plans 30–34 launches during these five fiscal years. ULA is expected to handle 60 percent of the launches while SpaceX will handle 40 percent of

7524-528: The rocket carried a Tesla Roadster belonging to SpaceX founder Elon Musk , with a mannequin dubbed "Starman" in the driver's seat. The second Falcon Heavy launch occurred on 11 April 2019, and all three booster rockets successfully returned to Earth . The third Falcon Heavy launch successfully occurred on 25 June 2019. Since then, Falcon Heavy has been certified for the National Security Space Launch (NSSL) program. Falcon Heavy

7623-551: The same booster on a second suborbital flight in January 2016. By October 2016, Blue had reflown, and landed successfully, that same launch vehicle a total of five times. The launch trajectories of both vehicles are very different, with New Shepard going straight up and down, whereas Falcon 9 has to cancel substantial horizontal velocity and return from a significant distance downrange. Both Blue Origin and SpaceX also have additional reusable launch vehicles under development. Blue

7722-582: The second-stage engine . At a press conference at the National Press Club in Washington, D.C., on 5 April 2011, Musk stated that Falcon Heavy would "carry more payload to orbit or escape velocity than any vehicle in history, apart from the Saturn V Moon rocket ... and Soviet Energia rocket". In the same year, with the expected increase in demand for both variants, SpaceX announced plans to expand manufacturing capacity "as we build towards

7821-469: The side boosters separate, three engines in each continues to burn for a few seconds in order to control the booster's trajectory safely away from the rocket. The grid fins then deploy as the boosters turn back to Earth , followed by the landing legs. The side boosters land softly on the ground in fully/partially reusable launch configuration. The center core continues to fire until stage separation. In fully reusable launches, its grid fins and legs deploy and

7920-436: The side boosters sooner, allowing their earlier separation to reduce the mass being accelerated. This would leave most of the center core propellant available after booster separation. Musk stated in 2016 that crossfeed would not be implemented. Instead, the center booster throttles down shortly after liftoff to conserve fuel, and resumes full thrust after the side boosters have separated. At an appearance in May 2004 before

8019-496: The song actually used for the launch was " Life on Mars "), and that it would be launched into an orbit around the Sun that will reach the orbit of Mars . He released pictures in the following days. The car had three cameras attached to provide "epic views". On December 28, 2017, the Falcon Heavy was moved to the launch pad in preparation of a static fire test of all 27 engines, which was expected on 19 January 2018. However, due to

8118-428: The standard procedure for all orbital launch vehicles flown prior to that time. Both were subsequently demonstrated on actual orbital nominal flights, although both also had an abort mode during launch that could conceivably allow the crew to land the spaceplane following an off-nominal launch. In the 2000s, both SpaceX and Blue Origin have privately developed a set of technologies to support vertical landing of

8217-410: The success of the maiden flight: There's a real good chance the vehicle won't make it to orbit ... I hope it makes it far enough away from the pad that it does not cause pad damage. I would consider even that a win, to be honest. In December 2017, Musk tweeted that the dummy payload on the maiden Falcon Heavy launch would be his personal Tesla Roadster playing David Bowie 's " Space Oddity " (though

8316-502: The surface of the Earth. To reach orbit, the vehicle must travel vertically to leave the atmosphere and horizontally to prevent re-contacting the ground. The required velocity varies depending on the orbit but will always be extreme when compared to velocities encountered in normal life. Launch vehicles provide varying degrees of performance. For example, a satellite bound for Geostationary orbit (GEO) can either be directly inserted by

8415-494: The two providers of Phase 2. Proposals were due December 15, 2023 and awards are expected in mid to late 2024. Phase 3 Lane 1 awardees were SpaceX, Blue Origin and ULA. The vehicles being: Falcon 9 , New Glenn and Vulcan Centaur , respectively. Launch vehicle A launch vehicle is typically a rocket -powered vehicle designed to carry a payload (a crewed spacecraft or satellites ) from Earth's surface or lower atmosphere to outer space . The most common form

8514-562: The two side boosters are recovered. The partially reusable Falcon Heavy falls into the heavy-lift range of launch systems, capable of lifting 20–50 t (44,000–110,000 lb) into low Earth orbit (LEO), under the classification system used by a NASA human spaceflight review panel. A fully expendable Falcon Heavy is in the super heavy-lift category with a maximum payload of 64 t (141,000 lb) to low Earth orbit. The initial concept (Falcon 9-S9 2005) envisioned payloads of 24.75 t (54,600 lb) to LEO, but by April 2011 this

8613-455: The various versions of Falcon Heavy priced at US$ 80–125 million in 2011, US$ 83–128 million in 2012, US$ 77–135 million in 2013, US$ 85 million for up to 6.4 t (14,000 lb) to GTO in 2014, US$ 90 million for up to 8 t (18,000 lb) to GTO in 2016. From 2017 to early 2022, the price has been stated at US$ 150 million for 63.8 t (141,000 lb) to LEO or 26.7 t (59,000 lb) to GTO (fully expendable). This equates to

8712-492: The vehicle at launch is 70 m (230 ft), and the total fueled mass is 1,420 t (3,130,000 lb). Without recovery of any stage, the Falcon Heavy can theoretically inject a 63.8 t (141,000 lb) payload into a low Earth orbit, or 16.8 t (37,000 lb) to Venus or Mars . However, because of the structural limitations the maximum weight Falcon Heavy can lift is reduced. The Falcon Heavy includes first-stage recovery systems , to allow SpaceX to return

8811-400: Was a rocket design with two main solid stages, a cryogenic upper stage, and the possibility of additional solid-rocket strap-on boosters. As of 2019, the first flight has been stated by NGIS to be expected in 2021. In the event, no phase 2 funding from the US government was forthcoming after August 2020 when ULA Vulcan and SpaceX were selected by the Air Force. In 2020, Northrop Grumman announced

8910-423: Was designed to be able to carry humans into space beyond low Earth orbit , although as of February 2018 , SpaceX does not intend to transport people on Falcon Heavy, nor pursue the human-rating certification process to transport NASA astronauts . Both Falcon Heavy and Falcon 9 are expected to eventually be superseded by the Starship super-heavy lift launch vehicle, currently being developed. Concepts for

9009-459: Was designed to meet or exceed all current requirements of human rating. The structural safety margins are 40% above flight loads, higher than the 25% margins of other rockets. Falcon Heavy was designed from the outset to carry humans into space and it would restore the possibility of flying crewed missions to the Moon or Mars. The first stage is powered by three Falcon 9 derived cores, each equipped with nine Merlin 1D engines. The Falcon Heavy has

9108-413: Was one that used a 9-engine first stage—the Falcon 9. The Falcon Heavy was developed using private capital with Musk stating that the cost was more than US$ 500 million. No government financing was provided for its development. The Falcon Heavy design is based on Falcon 9 's fuselage and engines. By 2008, SpaceX had been aiming for the first launch of Falcon 9 in 2009, while "Falcon 9 Heavy would be in

9207-453: Was originally designed with a "propellant crossfeed" capability, whereby the center core engines would be supplied with fuel and oxidizer from the two side cores until their separation . This approach had previously been proposed by Vladimir Chelomei for the UR-700 launch system. Operating all engines at full thrust from launch, with fuel supplied mainly from the side boosters, would deplete

9306-489: Was planning for a first launch of Falcon Heavy from Vandenberg Air Force Base , California on the United States west coast in 2013. SpaceX refurbished Launch Complex 4E at Vandenberg AFB to accommodate Falcon 9 and Heavy. The first launch from the Cape Canaveral , Florida east coast launch complex was planned for late 2013 or 2014. Due partly to the failure of SpaceX CRS-7 in June 2015, SpaceX rescheduled

9405-425: Was projected to be up to 53 t (117,000 lb) with geostationary transfer orbit (GTO) payloads up to 12 t (26,000 lb). Later reports in 2011 projected higher payloads beyond LEO, including 19 t (42,000 lb) to geostationary transfer orbit, 16 t (35,000 lb) to translunar trajectory , and 14 t (31,000 lb) on a trans-Martian orbit to Mars . By late 2013, SpaceX raised

9504-426: Was retired in 2024. Competitors from 2024 onwards may include SpaceX's Starship (100+ t to LEO), Blue Origin's New Glenn (45 t to LEO), Relativity Space 's Terran R (34 t to LEO), and United Launch Alliance (ULA) Vulcan Centaur (27 t to LEO). Due to improvements to the performance of Falcon 9 , some of the heavier satellites flown to GTO, such as Intelsat 35e and Inmarsat-5 F4, were launched before

9603-524: Was switched to a Falcon 9 Full Thrust due to the increased liftoff capacity. The remaining contract covered the launch of Inmarsat-6 F1 in 2020 on a Falcon 9 . In December 2012, SpaceX announced its first Falcon Heavy launch contract with the United States Department of Defense (DoD). The United States Air Force Space and Missile Systems Center awarded SpaceX two Evolved Expendable Launch Vehicle (EELV)-class missions, including

9702-480: Was to evolve to more closely match commercial practice. The initial bids came from four major defense contractors: Lockheed Martin , Boeing , McDonnell Douglas , and Alliant Techsystems . Each of the bids included a variety of concepts. Boeing initially proposed using the RS-25 Space Shuttle main engine. In October 1998 two initial launch services contracts (known as Buy 1) were awarded. Along with

9801-596: Was used to place a 4-kilogram payload ( TRICOM-1R ) into orbit in 2018. Orbital spaceflight requires a satellite or spacecraft payload to be accelerated to very high velocity. In the vacuum of space, reaction forces must be provided by the ejection of mass, resulting in the rocket equation . The physics of spaceflight are such that rocket stages are typically required to achieve the desired orbit. Expendable launch vehicles are designed for one-time use, with boosters that usually separate from their payload and disintegrate during atmospheric reentry or on contact with
