ULA began development of the Vulcan Centaur in 2014 as replacement for both the Atlas and Delta rocket families. The Vulcan Centaur completed its maiden flight in January 2024. The primary customers of ULA are

8418-543: The construction is completed, Tiangong will enter the application and development phase, which is poised to last for no less than 10 years. The European Space Agency began development of the Hermes shuttle spaceplane in 1987, to be launched on the Ariane 5 expendable launch vehicle. It was intended to dock with the European Columbus space station . The projects were canceled in 1992 when it became clear that neither cost nor performance goals could be achieved. No Hermes shuttles were ever built. The Columbus space station

8540-399: The construction of which took place from 1986 to 1996. Mir orbited at an altitude of 354 kilometers (191 nautical miles), at an orbital inclination of 51.6°. It was occupied for 4,592 days and made a controlled reentry in 2001. The Space Shuttle started flying in 1981, but the US Congress failed to approve sufficient funds to make Space Station Freedom a reality. A fleet of four shuttles

8662-420: The cost of ULA's launches were approximately US$ 460 million each and proposed a price of US$ 90 million to provide similar launches. In response, Gass said ULA's average launch price was US$ 225 million, with future launches as low as US$ 100 million. In a leadership change at ULA in August 2014, Tory Bruno assumed the CEO position, marking a new strategic direction for the company. Under Bruno's leadership, ULA

8784-408: The crew. Notably, Starliner missions use a unique Atlas V configuration: two solid rocket boosters, no payload fairing, and a dual-engine Centaur second stage for a shallower launch profile and reduced crew G-forces. This configuration stands 172 feet tall, and ULA was contracted for nine Starliner missions with Atlas V. The Interim Cryogenic Propulsion Stage (ICPS) provides the second stage boost for

8906-431: The decades, a number of spacecraft have been proposed for spaceliner passenger travel. Somewhat analogous to travel by airliner after the middle of the 20th century, these vehicles are proposed to transport large numbers of passengers to destinations in space, or on Earth via suborbital spaceflights . To date, none of these concepts have been built, although a few vehicles that carry fewer than 10 persons are currently in

9028-517: The delivery of nuclear weapons , producing rockets large enough to be adapted to carry the first artificial satellites into low Earth orbit . After the first satellites were launched in 1957 and 1958 by the Soviet Union, the US began work on Project Mercury , with the aim of launching men into orbit. The USSR was secretly pursuing the Vostok program to accomplish the same thing, and launched

9150-697: The design contract included NASA paying Dynetics US$ 253 million in design development funding. The other teams selected in 2020 were the ' National Team '—led by Blue Origin but including Lockheed Martin , Northrop Grumman , and Draper (with US$ 579 million in NASA design funding) and SpaceX (with US$ 135 million in NASA funding). At the end of the ten-month program on 28 February 2021, NASA had planned to evaluate which contractors would be offered contracts for initial demonstration missions and select firms for development and maturation of their lunar lander system designs. However, on 27 January 2021, NASA informed each of

9272-447: The engines to continue building Atlas V as it developed a replacement rocket. At the time of the announcement they could fly 29 more missions and all of them had been sold, so no new orders would be accepted. ULA faces an uncertain future. In 2023, the company announced that it was for sale. In December 2023, it was announced that Jeff Bezos was looking at purchasing the company to merge it with Blue Origin, which he also owns. When

9394-460: The entire fully fueled lunar vehicle into lunar orbit using its Exploration Upper Stage . The ALPACA is refueled in lunar orbit in four Vulcan Centaur flights. The ALPACA can be reused for both crewed lunar landings and autonomous cargo landings. The first ALPACA will be reused autonomously after its first crewed landing as a proof of concept for NASA. In order to prevent boil-off, refueling and landing will take place in 2-3 week intervals. Long term,

9516-741: The fifth and sixth Wideband Global SATCOM satellites WGS-5 and WGS-6 , as well as NROL-65 . In 2014, ULA's Atlas V orbited the TDRS-12 communications satellite in January, the WorldView-3 commercial satellite in August 2014, and the CLIO communications satellite during September and October 2014. Atlas rockets also carried the satellites DMSP-5D-3/F19, NROL-67, NROL-33, and NROL-35. Delta IV rockets orbited GPS satellites and two Geosynchronous Space Situational Awareness Program satellites, and in July 2014, NASA's Orbiting Carbon Observatory 2

9638-502: The first American in orbit, aboard Friendship 7 on a Mercury-Atlas rocket . The USSR launched five more cosmonauts in Vostok capsules , including the first woman in space, Valentina Tereshkova , aboard Vostok 6 on 16 June 1963. Through 1963, the US launched a total of two astronauts in suborbital flights and four into orbit. The US also made two North American X-15 flights ( 90 and 91 , piloted by Joseph A. Walker ), that exceeded

9760-650: The first Chinese taikonaut, Yang Liwei , went to space as part of Shenzhou 5 , the first Chinese human spaceflight. As of March 2024, humans have not traveled beyond low Earth orbit since the Apollo 17 lunar mission in December 1972. Currently, the United States, Russia, and China are the only countries with public or commercial human spaceflight-capable programs . Non-governmental spaceflight companies have been working to develop human space programs of their own, e.g. for space tourism or commercial in-space research . The first private human spaceflight launch

9882-687: The first U.S. Space Force National Security Mission. In May 2020, ULA launched an Atlas V rocket carrying the USSF-7 mission with the X-37B spaceplane for the U.S Space Force and the mission honored victims of the COVID-19 pandemic as well as first responders , health professionals , military personnel, and other essential workers . On 30 July 2020, Atlas V in the 541 configuration successfully launched Perseverance and Ingenuity as part of Mars 2020 towards Mars. In November 2020, ULA launched NROL-101,

10004-430: The first human into space, the cosmonaut Yuri Gagarin . On 12 April 1961, Gagarin was launched aboard Vostok 1 on a Vostok 3KA rocket and completed a single orbit. On 5 May 1961, the US launched its first astronaut , Alan Shepard , on a suborbital flight aboard Freedom 7 on a Mercury-Redstone rocket . Unlike Gagarin, Shepard manually controlled his spacecraft's attitude . On 20 February 1962, John Glenn became

10126-429: The first manual rendezvous and docking with Shenzhou 9 , which carried China's first female astronaut Liu Yang . In September 2016, Tiangong 2 was launched into orbit. It was a space laboratory with more advanced functions and equipment than Tiangong 1 . A month later, Shenzhou 11 was launched and docked with Tiangong 2 . Two astronauts entered Tiangong 2 and were stationed for about 30 days, verifying

10248-468: The first spacewalk, but overcame the early Soviet lead by performing several spacewalks, solving the problem of astronaut fatigue caused by compensating for the lack of gravity, demonstrating the ability of humans to endure two weeks in space, and performing the first space rendezvous and docking of spacecraft. The US succeeded in developing the Saturn V rocket necessary to send the Apollo spacecraft to

10370-584: The first woman to enter space through the United States program.Since then, eleven other countries have allowed women astronauts. The first all-female spacewalk occurred in 2018, by Christina Koch and Jessica Meir . These two women had both participated in separate spacewalks with NASA. The first mission to the Moon with a woman aboard is planned for 2024. Despite these developments, women are still underrepresented among astronauts and especially cosmonauts. More than 600 people have flown in space but only 75 have been women. Issues that block potential applicants from

10492-528: The flight than the center CBC. The 5 meter diameter composite fairing was standard on the Delta IV Heavy, with an aluminum isogrid fairing also available. The aluminum trisector (three-part) fairing was built by Boeing and derived from a Titan IV fairing. The trisector fairing was first used on the DSP-23 flight. Delta IV Heavy had 16 launches in its lifetime. Statistics are up-to-date as of 4 October 2024 . The first launch conducted by ULA

10614-491: The formation of ULA. Delta II was part of the Delta rocket family and entered service in 1989. ULA flew thirty missions using Delta II starting in 2006. Delta II vehicles included the Delta 6000 and the two later Delta 7000 variants ("Light" and "Heavy"). The rocket flew its final mission ICESat-2 on 15 September 2018. A nearly-complete Delta II, made from flight-qualified spare parts, is displayed in its 7320-10 configuration in

10736-540: The fully integrated two-stage system occurred in April 2023. A modified version of Starship is being developed for the Artemis program . United Launch Alliance United Launch Alliance, LLC ( ULA ) is an American launch service provider formed in December 2006 as a joint venture between Lockheed Martin Space and Boeing Defense, Space & Security . The company designs, assembles, sells and launches rockets, but

10858-540: The hydrogen tank and are covered by the interstage during launch. Only three ICPS stages were ever built, one for each of the Artemis I , II , and III missions. Following these missions, the ICPS will be replaced by the Exploration Upper Stage built by Boeing. Delta II was an expendable launch system that was originally designed and built by McDonnell Douglas , and was later built by Boeing prior to

10980-565: The initial configuration (Block 1) of NASA's Space Launch System (SLS). The ICPS design was based on the Delta Cryogenic Second Stage employed by ULA's Delta launch vehicles. The ICPS is positioned atop the SLS core stage and directly below the Orion spacecraft . The ICPS has a cylindrical liquid hydrogen tank, structurally designed to bear launch loads, while the liquid oxygen and single RL10B-2 engine are suspended from

11102-407: The interior layout and its ingress / egress capabilities. The ALPACA is designed to be launched on ULA's Vulcan Centaur rocket. Vulcan launches the full ALPACA vehicle to NRHO . Four more Vulcan launches carry either a Centaur Tanker to refuel the liquid methane, liquid oxygen tanks of the lander or a logistics vehicle (MULE). Alternatively, if available, a SLS Block 1B could launch

11224-558: The joint venture was founded in 2006, ULA inherited the Atlas rocket family from Lockheed Martin and the Delta rocket family from Boeing. As of 2024, the Delta family has been retired and the Atlas V is in the process of being retired. ULA began development of the Vulcan Centaur in 2014 as replacement for both the Atlas and Delta rocket families. The Vulcan Centaur is a heavy-lift launch vehicle developed by ULA integrating technology from both its prior Atlas and Delta rocket families along with advancements. Vulcan has been designed to meet

11346-458: The largest member of the Delta IV family. Boeing flew it on one mission prior to the formation of ULA, and ULA on fifteen missions from 2007 to 2024. Its final launch was April 9, 2024 at Cape Canaveral Space Force Station . The Delta IV Heavy combined a 5 m (16 ft) diameter DCSS and payload fairing with two additional CBCs. These are strap-on boosters which are separated earlier in

11468-490: The limits of their single-pilot Vostok capsule by adapting it to a two or three-person Voskhod capsule to compete with Gemini. They were able to launch two orbital flights in 1964 and 1965 and achieved the first spacewalk , performed by Alexei Leonov on Voskhod 2 , on 8 March 1965. However, the Voskhod did not have Gemini's capability to maneuver in orbit, and the program was terminated. The US Gemini flights did not achieve

11590-535: The lunar programs, but failed to develop the N1 rocket necessary for a human landing, and discontinued their lunar programs in 1974. Upon losing the Moon race they concentrated on the development of space stations , using the Soyuz as a ferry to take cosmonauts to and from the stations. They started with a series of Salyut sortie stations from 1971 to 1986. In 1969, Nixon appointed his vice president, Spiro Agnew , to head

11712-407: The next day, marking the first step of the realization of China's human spaceflight capability. Three more uncrewed missions were conducted in the next few years in order to verify the key technologies. On 15 October 2003 Shenzhou 5 , China's first crewed spaceflight mission, put Yang Liwei in orbit for 21 hours and returned safely back to Inner Mongolia , making China the third nation to launch

11834-458: The onboard human crew. Spacecraft can also be remotely operated from ground stations on Earth, or autonomously , without any direct human involvement. People trained for spaceflight are called astronauts (American or other), cosmonauts (Russian), or taikonauts (Chinese); and non-professionals are referred to as spaceflight participants or spacefarers . The first human in space was Soviet cosmonaut Yuri Gagarin , who launched as part of

11956-532: The past decade or so; as of 2017 , at least one of each type is under development. Both Virgin Galactic and Blue Origin have craft in active development : the SpaceShipTwo spaceplane and the New Shepard capsule, respectively. Both would carry approximately a half-dozen passengers up to space for a brief time of zero gravity before returning to the launch location. XCOR Aerospace had been developing

12078-635: The planned Space Station Freedom into the International Space Station (ISS). Construction of the station began in 1998. The station orbits at an altitude of 409 kilometers (221 nmi) and an orbital inclination of 51.65°. Several of the Space Shuttle's 135 orbital flights were to help assemble, supply, and crew the ISS. Russia has built half of the International Space Station and has continued its cooperation with

12200-438: The programs, and limit the space missions they are able to go on, are, for example: Sally Ride became the first American woman in space, in 1983. Eileen Collins was the first female Shuttle pilot, and with Shuttle mission STS-93 in 1999 she became the first woman to command a U.S. spacecraft. For many years, the USSR (later Russia) and the United States were the only countries whose astronauts flew in space. That ended with

12322-429: The purpose of the flight was purely symbolic. The two nations continued to compete rather than cooperate in space, as the US turned to developing the Space Shuttle and planning the space station, which was dubbed Freedom . The USSR launched three Almaz military sortie stations from 1973 to 1977, disguised as Salyuts. They followed Salyut with the development of Mir , the first modular, semi-permanent space station,

12444-511: The remaining cost of development, estimated at 75% of the cost, as of March 2018. The NSSL program purchased a prototype Vulcan launch in October 2018, and was awarded a contract in August 2020 to launch 60% of NSSL missions over a 5-year period beginning in 2024. The Vulcan Centaur was originally slated to conduct its maiden flight in 2019, however was delayed repeatedly. The inaugural flight occurred on January 8, 2024, successfully sending

12566-539: The requirements of the National Security Space Launch (NSSL) program and be capable of achieving human-rating certification to allow the launch of a vehicle such as the Boeing Starliner or Sierra Nevada Dream Chaser . The rocket was developed as ULA faced pressure to respond to growing competition from SpaceX and its reusable rockets and the need to phase out the RD-180 engine used on

12688-412: The scored the lowest. The largest issue identified was negative mass margins, meaning it wasn't able to carry out the listed mission without decreasing the mass of the lander. Human spaceflight Human spaceflight (also referred to as manned spaceflight or crewed spaceflight ) is spaceflight with a crew or passengers aboard a spacecraft , often with the spacecraft being operated directly by

12810-470: The time, the only humans in space are those aboard the ISS, which generally has a crew of 7, and those aboard Tiangong, which generally has a crew of 3. NASA and ESA use the term "human spaceflight" to refer to their programs of launching people into space. These endeavors have also formerly been referred to as "manned space missions", though this is no longer official parlance according to NASA style guides, which call for gender-neutral language . Under

12932-420: The viability of astronauts' medium-term stay in space. In April 2017, China's first cargo spacecraft, Tianzhou 1 docked with Tiangong 2 and completed multiple in-orbit propellant refueling tests, which marked the successful completion of the second phase of CMS. The third phase of CMS began in 2020. The goal of this phase is to build China's own space station, Tiangong . The first module of Tiangong ,

13054-516: Was a suborbital flight on SpaceShipOne on June 21, 2004. The first commercial orbital crew launch was by SpaceX in May 2020, transporting NASA astronauts to the ISS under United States government contract. Human spaceflight capability was first developed during the Cold War between the United States and the Soviet Union (USSR). These nations developed intercontinental ballistic missiles for

13176-685: Was a Delta II from Vandenberg Space Force Base on 14 December 2006, carrying the satellite USA-193 for the National Reconnaissance Office . The satellite failed shortly after launch and was intentionally destroyed on 21 February 2008, by an SM-3 missile that was fired from the Ticonderoga -class cruiser USS  Lake Erie . ULA's first Atlas V launch was in March 2007; it was an Atlas V variant 401 launching six military research satellites for Space Test Program (STP) 1. This mission also performed three burns of

13298-453: Was also used to launch a number of U.S. government non-military payloads and one commercial satellite. Delta IV had two main versions, which allowed the family to accommodate a range of payload sizes and masses; models includes Medium, which had four configurations, and the Heavy . Payloads that would previously fly on Medium moved to either Atlas V or Vulcan Centaur . Delta IV Heavy was

13420-618: Was announced as the first CEO of ULA and oversaw the merger of the two groups. Production was consolidated into one central plant in Decatur, Alabama while all engineering was moved into a facility in Littleton, Colorado . The parent companies retained responsibility for marketing and sales of the Delta and Atlas rockets. Cost pressures led ULA to announce it would lay off 350 of its 4,200 workers in early 2009, and decommissioned two of its seven launch pads . ULA also joined and later left

13542-472: Was built: Columbia , Challenger , Discovery , and Atlantis . A fifth shuttle, Endeavour , was built to replace Challenger , which was destroyed in an accident during launch that killed 7 astronauts on 28 January 1986. From 1983 to 1998, twenty-two Shuttle flights carried components for a European Space Agency sortie space station called Spacelab in the Shuttle payload bay. The USSR copied

13664-466: Was carried by a Delta II. Orion 's first test flight was launched by a Delta IV Heavy rocket in December 2014, as part of Exploration Flight Test-1 . A Delta II rocket orbited a Soil Moisture Active Passive satellite in January 2015. In March 2015, an Atlas V rocket carried NASA's Magnetospheric Multiscale Mission spacecraft, and a Delta IV rocket orbited the GPS IIF-9 satellite on behalf of

13786-604: Was carried in November 2016, as was the WorldView-4 imaging satellite. In December 2016, the Wideband Global SATCOM's eighth satellite WGS-8 was launched on a Delta IV Medium rocket, and an Atlas V carried the EchoStar XIX communications satellite on behalf of Hughes Communications . In March 2017, WGS-9 was orbited by a Delta IV. Atlas V rockets carried NRO satellites, TDRS-M , and

13908-547: Was initiated in 2019, and in April 2020, Dynetics won a US$ 253 million contract from NASA for a year-long design concept study to be completed in early 2021. NASA had intended to subsequently issue build and test contracts to one or two of the three 2020 awardees in order to advance the human landing element of the Artemis Program. In the event, the Dynetics HLS proposal was not selected by NASA in April 2021, and

14030-669: Was launched in May 2022. A crewed flight to fully certify Starliner was launched in June 2024. Similar to SpaceX, development funding has been provided by a mix of government and private funds. Virgin Galactic is developing SpaceshipTwo , a commercial suborbital spacecraft aimed at the space tourism market. It reached space in December 2018. Blue Origin is in a multi-year test program of their New Shepard vehicle and has carried out 16 uncrewed test flights as of September 2021, and one crewed flight carrying founder Jeff Bezos , his brother Mark Bezos , aviator Wally Funk , and 18-year old Oliver Daemen on July 20, 2021. Over

14152-435: Was not selected but also budgetary constraints. Although NASA had previously stated it wanted to contract for multiple dissimilar Human Landing Systems, "only one design was selected for an initial uncrewed demonstration and the first crewed landing, due to significant budget constraints" based on the HLS funds allocated by Congress . NASA has indicated that Dynetics would be free to compete for subsequent missions that are not

14274-487: Was not until the 1980s that another woman entered space. At the time, all astronauts were required to be military test pilots; women were not able to enter this career, which is one reason for the delay in allowing women to join space crews. After the rules were changed, Svetlana Savitskaya became the second woman to enter space; she was also from the Soviet Union . Sally Ride became the next woman to enter space and

14396-516: Was planned by 1993, but the program was canceled due to lack of funding and the dissolution of the Soviet Union in 1991. Two more orbiters were never completed, and the one that performed the uncrewed flight was destroyed in a hangar roof collapse in May 2002. The dissolution of the Soviet Union in 1991 brought an end to the Cold War and opened the door to true cooperation between the US and Russia. The Soviet Soyuz and Mir programs were taken over by

14518-643: Was proposed for space tourism. According to a press release from the Iraqi News Agency dated 5 December 1989, there was only one test of the Al-Abid space launcher, which Iraq intended to use to develop its own crewed space facilities by the end of the century. These plans were put to an end by the Gulf War of 1991 and the economic hardships that followed. Under the George W. Bush administration,

14640-533: Was reconfigured as the European module of the same name on the International Space Station. Japan ( NASDA ) began the development of the HOPE-X experimental shuttle spaceplane in the 1980s, to be launched on its H-IIA expendable launch vehicle. A string of failures in 1998 led to funding reductions, and the project's cancellation in 2003 in favor of participation in the International Space Station program through

14762-507: Was to visit and study the Sun 's outer corona in August 2018. It was also the Delta IV Heavy with a Star-48BV kick stage, and the highest-ever spacecraft velocity. The company launched the final Delta II rocket, carrying ICESat-2 from Vandenberg Air Force Base SLC-2 on 15 September 2018. This marks the last launch of a Delta family rocket based on the original Thor IRBM . On 22 August 2019, ULA launched its last Delta IV Medium rocket for

14884-408: Was under pressure to reduce costs to better compete with SpaceX and its partially reusable rockets, replace its Russian-made RD-180 with more efficient western-made engines, and introduce a next-generation launch vehicle. The company's high cost to launch left the company with few commercial and civil satellite launch customers, and increasingly reliant on U.S. military and spy agency contracts. After
