On 15 August 2018, Indian Prime Minister Narendra Modi , declared India will independently send humans into space before the 75th anniversary of independence in 2022. In 2019, ISRO revealed plans for a space station by 2030, followed by a crewed lunar mission. The program envisages the development of
246-453: A Russian-European program, because the modular structure (see below) allows for a division of design responsibilities between the partners (for instance, Russia could be in charge of the overall design of the reentry capsule, while ESA works on the habitation module etc.). About €15 million were pledged for the CSTS program at ESA's regular meeting on June 21 and June 22, 2006. Further funding of

The group proposed an ambitious Space Transportation System based on a reusable Space Shuttle , which consisted of a winged, internally fueled orbiter stage burning liquid hydrogen, launched with a similar, but larger kerosene -fueled booster stage, each equipped with airbreathing jet engines for powered return to
410-674: A crewed derivative of the ATV spacecraft into uncertainty. As of summer 2015, no known new developments on the CSTS/ACTS project had been disclosed to the public. In 2004, U.S. President George W. Bush announced the Vision for Space Exploration , a program that included the United States return to the Moon by 2020 and a crewed mission to Mars by 2030. For these purposes the Orion spacecraft
492-600: A design and collaboration study in December 2005, mainly because certain member states felt that ESA would just be a minor industrial contributor to the program, while Russia would actually develop and design the Kliper spacecraft. On the Russian side, the concept of Advanced Crew Transportation System, ACTS, conceived as a sort of "Euro-Soyuz", emerged during 2006, when Russian authorities realized that their proposal to replace
574-591: A fully-autonomous orbital vehicle capable of carrying 2 or 3 crew members to an about 300 km (190 mi) low Earth orbit and bringing them safely back home. Since 2008, the Japan Aerospace Exploration Agency has developed the H-II Transfer Vehicle cargo-spacecraft-based crewed spacecraft and Kibō Japanese Experiment Module –based small space laboratory. NASA is developing a plan to land humans on Mars by
656-577: A general cooperation, not a cooperation in developing the Orion, the actual vehicle to be used for Moon missions, which would be an entirely American built spacecraft. Since 2004, ESA had been in talks with Roscosmos on cooperation for the development of Kliper , the Russian successor project to the Soyuz spacecraft , which has been in service since 1967. While ESA's management was enthusiastic about this cooperation, their member states turned down funding for
738-664: A human into orbit independently. The goal of the second phase of CMS was to make technology breakthroughs in extravehicular activities (EVA, or spacewalk), space rendezvous , and docking to support short-term human activities in space. On 25 September 2008 during the flight of Shenzhou 7 , Zhai Zhigang and Liu Boming completed China's first EVA. In 2011, China launched the Tiangong 1 target spacecraft and Shenzhou 8 uncrewed spacecraft. The two spacecraft completed China's first automatic rendezvous and docking on 3 November 2011. About 9 months later, Tiangong 1 completed
820-580: A runway at the Kennedy Space Center launch site. Other components of the system included a permanent, modular space station; reusable space tug ; and nuclear interplanetary ferry, leading to a human expedition to Mars as early as 1986 or as late as 2000, depending on the level of funding allocated. However, Nixon knew the American political climate would not support congressional funding for such an ambition, and killed proposals for all but
902-462: A second-class partner. " In a July 2006 interview with New Scientist, NASA Administrator Michael Griffin however suggested interest in international cooperation in the general context of NASA's Moon exploration plans. " The US will return to the Moon but we think we will do it better, that it will be more rewarding for all, if it can do it in the company of as many of our ISS partners as we can, and with new partners. " In this statement Griffin speaks of

The descent module somewhat resembles the American Apollo spacecraft command module while the orbital module resembles a man-rated version of the ATV. Manuel Valls, head of Policy and Plans Department in ESA's Directorate of Human Spaceflight, Microgravity, and Exploration Program noted on the question of available launch vehicles for
1066-698: A solo project modeling the ACTS after the ATV craft that carries supplies to the International Space Station. At the start of the new decade, Russian plans for the development of the PPTS became gradually postponed. In January 2013, NASA announced that ESA would build the service module for the Orion test flight Artemis 1 , which is a major step in international cooperation in deep space exploration. Subsequently, ESA signed an agreement with NASA that saw it shift part of its ATV development focus towards
1148-473: A third, successful attempt at crewed spaceflight. To achieve independent human spaceflight capability, China developed the Shenzhou spacecraft and Long March 2F rocket dedicated to human spaceflight in the next few years, along with critical infrastructures like a new launch site and flight control center being built. The first uncrewed spacecraft, Shenzhou 1 , was launched on 20 November 1999 and recovered
1230-591: Is far more effective [...] because we could use – and this is our intention – existing launch vehicles or launch vehicles with minimal development." This means that CSTS would have had a tight mass budget, as only launchers with a maximum payload capacity in the class of Ariane 5 , Proton or Angara will be available for a launch. With two launches and low Earth Orbit ( LEO ) docking that means that CSTS together with an Earth Departure Stage will not be able to weigh more than about 45 to 50 tonnes in LEO (note however that this
1312-415: Is just for the lunar spacecraft, a lunar lander is not integrated in this calculation). An ESA presentation from June 13, 2006 presents a lunar orbital mission of the CSTS spacecraft with 3 launches, of which two are propulsion modules to propel the spacecraft to a trans-lunar trajectory. Such a scenario, while more complicated than the 2-stage approach mentioned by Manuel Valls, gives more leeway in terms of
1394-443: Is similar to the gap between the end of Apollo in 1975 and the first Space Shuttle flight in 1981, and is referred to by a presidential Blue Ribbon Committee as the U.S. human spaceflight gap. Since the early 2000s, a variety of private spaceflight ventures have been undertaken. As of November 2024, SpaceX and Boeing have launched humans to orbit, while Blue Origin has launched 8 crewed flights, six of which crossed

As an alternative to HOPE-X, NASDA in 2001 proposed the Fuji crew capsule for independent or ISS flights, but the project did not proceed to the contracting stage. From 1993 to 1997, the Japanese Rocket Society , Kawasaki Heavy Industries , and Mitsubishi Heavy Industries worked on the proposed Kankoh-maru vertical-takeoff-and-landing single-stage-to-orbit reusable launch system. In 2005, this system
1640-643: The Constellation program included plans for retiring the Space Shuttle program and replacing it with the capability for spaceflight beyond low Earth orbit. In the 2011 United States federal budget , the Obama administration canceled Constellation for being over budget and behind schedule, while not innovating and investing in critical new technologies. As part of the Artemis program , NASA is developing

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

Gemini's objective was to support Apollo by developing American orbital spaceflight experience and techniques to be used during the Moon mission. Meanwhile, the USSR remained silent about their intentions to send humans to the Moon and proceeded to stretch
2296-569: The Shuguang spacecraft. Nineteen PLAAF pilots were selected for this goal in March 1971. The Shuguang-1 spacecraft, to be launched with the CZ-2A rocket, was designed to carry a crew of two. The program was officially canceled on 13 May 1972 for economic reasons. In 1992, under China Manned Space Program (CMS), also known as "Project 921", authorization and funding was given for the first phase of

The first step has begun with Artemis I in 2022, sending an uncrewed Orion spacecraft to a distant retrograde orbit around the Moon and returning it to Earth after a 25-day mission. SpaceX is developing Starship , a fully reusable two-stage system, with near-Earth and cislunar applications and an ultimate goal of landing on Mars. The upper stage of the Starship system, also called Starship, has had 9 atmospheric test flights as of September 2021. The first test flight of
2706-498: The ACTS plan. As of late November 2008, the project funding had been limited to a feasibility study with a launch of an actual vehicle possible no earlier than 2017. In 2009, Russia decided it would go with a version of the original design of the CSTS and renamed it the Prospective Piloted Transport System (PPTS). ESA decided to go with an ACTS (Advanced Crew Transportation System), an evolution of

In mid-2009 EADS Astrium was awarded a €21 million study to design a crewed variation of the European ATV vehicle which is believed to now be the basis of the ACTS design. Since early 2013, ESA and NASA have begun cooperation on developing the European Service Module for the current version of the Orion spacecraft . This has cast previous ESA efforts concerning
2870-465: The CSTS spacecraft that "although nothing at this stage is definitive, [...] both the Russians and we think that it is only prudent, and most efficient and effective, to go with 2 stages and not one. The 1-stage has been done already with Saturn V and Apollo. To do that now would entail the development of quite a new launcher and that will take time and money like hell, if I may say. Going with two stages
2952-503: The CSTS spacecraft. It had not been decided what launcher would carry the spacecraft to orbit, however Manuel Valls indicated that beside a Russian rocket, Ariane 5 could possibly also function as the carrier rocket. At about the same time as FKA and ESA announced their plans for the CSTS spacecraft, the German space agency, DLR , together with EADS Astrium announced their support for the ATV evolution proposal. This proposal envisioned
3034-564: The CSTS' mass budget. EADS Astrium Space Transportation concepts for adapting the Ariane 5 ECB for lunar exploration could increase Ariane 5 LEO performance to 27 tonnes. These performance adaptions would entail the use of a composite solid rocket casing, and upgrades to the Vulcain Mk III and Vinci (ECSB) engines. Both the ESA's site at French Guiana and the planned Russian spaceport at Vostochny were considered as launch sites for

After the December 2005 rejection of Kliper by ESA, Jean-Jacques Dordain emphasized that a collaboration with Russia on a new spacecraft could still be decided in June 2006. On June 13, 2006 the press reported that the winged Kliper project had been replaced by a study to develop a capsule under the Advanced Crew Transportation System program that ESA would fund. This rejection by ESA notwithstanding, Kliper

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
4100-431: 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

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 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
4346-482: The development of a modified ATV with a reentry capsule that would be return cargo from the ISS by 2013 and in a second phase a crewed vehicle based on this modified ATV by 2017. Those dates were later revised to 2015 and 2020 respectively. This proposal was presented to ESA's governing body at its meeting in November 2008 and received funding for an initial development phase of a cargo return vehicle that may be ready by 2017. The ATV Evolution concept may have contributed to
4428-585: The end of the CSTS project. However, the head of the ESA denies that the ATV evolution plan is an alternative and talks are still ongoing as to whether or not to continue funding the ACTS plan. In 2009, Russia had decided to keep the general design of the CSTS spacecraft for their new crewed spacecraft, which eventually developed into the PPTS project. In the meantime, the European Space Agency took on

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 ,
5904-444: Was Soviet cosmonaut Yuri Gagarin , who launched as part of the Soviet Union's Vostok program on 12 April 1961 at the beginning of the Space Race . On 5 May 1961, Alan Shepard became the first American in space, as part of Project Mercury . Humans traveled to the Moon nine times between 1968 and 1972 as part of the United States' Apollo program , and have had a continuous presence in space for 24 years and 26 days on
5986-516: 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
6068-404: Was a Russian program that could still have been funded entirely by FKA – although this was unlikely if Russia and Europe would really have gone forward with the CSTS concept together. In mid-July 2006, the Kliper tender process was cancelled, after having no winners. Reasons given for choosing the CSTS over Kliper included that the former would offer Europe the possibility to be a full partner in
6150-417: 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
6232-431: Was conceived as a basic strategic plan to keep a viable European human spaceflight program alive. CSTS had completed an initial study phase, which lasted 18 months from September 2006 to spring 2008, before the project was shut down before an ESA member state conference in November 2008. However, the head of the ESA denies that the ATV evolution plan is an alternative and talks are ongoing as to whether to continue funding
6314-669: 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
6396-487: 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
6478-516: 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
6560-643: 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,
6642-533: 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
6724-483: Was to be developed. ESA officials inquired whether they could be part of this program for exploration, however received a negative response. Jean-Jacques Dordain , ESA's General Director stated with regard to this rejection by NASA: " I have been told by Mike Griffin and Marburger that the CEV is not for international cooperation. But if Europe is not involved in the next-generation transportation systems, we will stay forever
