History of spaceflight

For the historical period, see Space Age.

For a chronological guide, see Timeline of spaceflight.

Spaceflight began in the 20th century following theoretical and practical breakthroughs by Konstantin Tsiolkovsky, Robert H. Goddard, and Hermann Oberth, each of whom published works proposing rockets as the means for spaceflight. ^[a] The first successful large-scale rocket programs were initiated in Nazi Germany by Wernher von Braun. The Soviet Union took the lead in the post-war Space Race, launching the first satellite, ^[1] the first animal, ^{[2] : 155} the first human ^[3] and the first woman ^[4] into orbit. The United States landed the first men on the Moon in 1969. Through the late 20th century, France, the United Kingdom, Japan, and China were also working on projects to reach space.

Following the end of the Space Race, spaceflight has been characterized by greater international cooperation, cheaper access to low Earth orbit and an expansion of commercial ventures. Interplanetary probes have visited all of the planets in the Solar System, and humans have remained in orbit for long periods aboard space stations such as Mir and the ISS. Most recently, China has emerged as the third nation with the capability to launch independent crewed missions, while operators in the commercial sector have developed reusable booster systems and craft launched from airborne platforms.In 2020, SpaceX became the first commercial operator to successfully launch a crewed mission to the International Space Station with Crew Dragon Demo-2.

Background

The number of spacewalks required to construct the International Space Station dwarfed the then existing experience base for this activity, a hurdle called the "Wall of EVA."

Description of a space station in Hermann Noordung's The Problem of Space Travel (1929).

At the beginning of the 20th century, there was a burst of scientific investigation into interplanetary travel, inspired by fiction by writers such as Jules Verne ( From the Earth to the Moon , Around the Moon ) and H.G. Wells ( The First Men in the Moon , The War of the Worlds ).^{[ citation needed ]}

The first realistic proposal for spaceflight was "Issledovanie Mirovikh Prostranstv Reaktivnimi Priborami", or "The Exploration of Cosmic Space by Means of Reaction Devices" by Konstantin Tsiolkovsky, published in 1903. ^[6]

Spaceflight became an engineering possibility with the work of Robert H. Goddard's publication in 1919 of his paper "A Method of Reaching Extreme Altitudes", where his application of the de Laval nozzle to liquid fuel rockets gave sufficient power for interplanetary travel to become possible. This paper was highly influential on Hermann Oberth and Wernher Von Braun, later key players in spaceflight.^{[ citation needed ]}

In 1929, the Slovene officer Hermann Noordung was the first to imagine a complete space station in his book The Problem of Space Travel. ^{[7] [8]}

The first rocket to reach space was a German V-2 rocket, on a vertical test flight in June 1944. ^[9] After the war ended, the research and development branch of the (British) Ordinance Office organised Operation Backfire which, in October 1945, assembled enough V-2 missiles and supporting components to enable the launch of three (possibly four, depending on source consulted) of them from a site near Cuxhaven in northern Germany. Although these launches were inclined and the rockets did not achieve the altitude necessary to be regarded as sub-orbital spaceflight, the Backfire report remains the most extensive technical documentation of the rocket, including all support procedures, tailored vehicles and fuel composition. ^[10]

Subsequently, the British Interplanetary Society proposed an enlarged man-carrying version of the V-2 called Megaroc . The plan, written in 1946, envisaged a three-year development programme culminating in the launch of test pilot Eric Brown on a sub-orbital mission in 1949. ^{[11] [12]}

The decision by the Ministry of Supply under Attlee's government to concentrate on research into nuclear power generation and sub-sonic passenger jet aircraft over supersonic atmospheric flight and spaceflight delayed the introduction of both of the latter, although only by a year in the case of supersonic flight, as the data from the Miles M.52 was handed to Bell Aircraft.^{[ citation needed ]}

In 1947, the US sent the first animals in space, fruit flies, although not into orbit, through a V-2 rocket launched from White Sands Missile Range, New Mexico. ^{[13] [14] [15]} On June 14, 1949, the US launched the first mammal into space, a rhesus macaque monkey named Albert II, on a sub-orbital flight, though Albert II died when the parachute failed. ^[16] On July 22, 1951, the Soviets launched the Soviet space dogs, Dezik and Tsygan, who were the first dogs in space and the first to safely return. ^[17]

Establishment and Space Race

First artificial satellites

Main article: Sputnik 1

The race began in 1957 when both the US and the USSR made statements announced they planned to launch artificial satellites during the 18-month long International Geophysical Year of July 1957 to December 1958. On July 29, 1957, the US announced a planned launch of the Vanguard by the spring of 1958, and on July 31, the USSR announced it would launch a satellite in the fall of 1957. ^{[18] [19]}

On October 4, 1957, the Soviet Union launched Sputnik 1, the first artificial satellite of Earth in the history of humankind.

Explorer 1 satellite, the third Satellite put into orbit, and the first by NASA

On November 3, 1957, the Soviet Union launched the second satellite, Sputnik 2, and the first to carry a living animal into orbit, a dog named Laika. Sputnik 3 was launched on May 15, 1958, and carried a large array of instruments for geophysical research and provided data on pressure and composition of the upper atmosphere, concentration of charged particles, photons in cosmic rays, heavy nuclei in cosmic rays, magnetic and electrostatic fields, and meteoric particles. After a series of failures with the program, the US succeeded with Explorer 1, which became the first US satellite in space, on February 1, 1958. This carried scientific instrumentation and detected the theorized Van Allen radiation belt. The US public shock over Sputnik 1 became known as the Sputnik crisis. On July 29, 1958, the US Congress passed legislation turning the National Advisory Committee for Aeronautics (NACA) into the National Aeronautics and Space Administration (NASA) with responsibility for the nation's civilian space programs. In 1959, NASA began Project Mercury to launch single-man capsules into Earth orbit and chose a corps of seven astronauts introduced as the Mercury Seven . ^[20]

First man in space

Main article: Vostok programme

Yuri Gagarin

On April 12, 1961, the USSR opened the era of crewed spaceflight, with the flight of the first cosmonaut (Russian name for space travelers), Yuri Gagarin. Gagarin's flight, part of the Soviet Vostok space exploration program, took 108 minutes and consisted of a single orbit of the Earth. ^[21]

On August 7, 1961, Gherman Titov, another Soviet cosmonaut, became the second man in orbit during his Vostok 2 mission. Titov orbited Earth 17 times in over 25 hours during his spaceflight. ^[22]

By June 16, 1963, the USSR launched a total of six Vostok cosmonauts, two pairs of them flying concurrently, and accumulating a total of 260 cosmonaut-orbits and just over sixteen cosmonaut-days in space.^{[ citation needed ]}

On May 5, 1961, the US launched its first suborbital Mercury astronaut, Alan Shepard, in the Freedom 7 capsule. ^{[23] [24]}

First woman in space

Further information: Women in space

Valentina Tereshkova

The first woman in space was former civilian parachutist Valentina Tereshkova, who entered orbit on June 16, 1963, aboard the Soviet mission Vostok 6. The chief Soviet spacecraft designer, Sergey Korolyov, conceived of the idea to recruit a female cosmonaut corps and launch two women concurrently on Vostok 5/6. However, his plan was changed to launch a male first in Vostok 5, followed shortly afterward by Tereshkova. The then first secretary of the Soviet Union, Nikita Khrushchev, spoke to Tereshkova by radio during her flight. ^[25]

On November 3, 1963, Tereshkova married fellow cosmonaut Andrian Nikolayev, who had previously flown on Vostok 3. ^[26] On June 8, 1964, she gave birth to the first child conceived by two space travelers. ^[27] The couple divorced in 1982, and Tereshkova went on to become a prominent member of the Communist Party of the Soviet Union. ^[28]

The second woman to fly to space was aviator Svetlana Savitskaya, aboard Soyuz T-7 on August 18, 1982. ^[29]

Competition develops

Khrushchev pressured Korolyov to quickly produce greater space achievements in competition with the announced Gemini and Apollo plans. Rather than allowing him to develop his plans for a crewed Soyuz spacecraft, he was forced to make modifications to squeeze two or three men into the Vostok capsule, calling the result Voskhod. Only two of these were launched. Voskhod 1 was the first spacecraft with a crew of three, who could not wear space suits because of size and weight constrictions. Alexei Leonov made the first spacewalk when he left the Voskhod 2 on March 8, 1965. He was almost lost in space when he had extreme difficulty fitting his inflated space suit back into the cabin through an airlock, and a landing error forced him and Voskhod 2 crewmate Pavel Belyayev to be lost in dense woods for hours before being found by the recovery crew and rescued days later.^{[ citation needed ]}

The start of crewed Gemini missions was delayed a year later than NASA had planned, but ten largely successful missions were launched in 1965 and 1966, allowing the US to overtake the Soviet lead by achieving space rendezvous (Gemini 6A) and docking (Gemini 8) of two vehicles, long duration flights of eight days (Gemini 5) and fourteen days (Gemini 7), and demonstrating the use of extra-vehicular activity to do useful work outside a spacecraft (Gemini 12).^{[ citation needed ]}

The USSR made no crewed flights during this period but continued to develop its Soyuz craft and secretly accepted Kennedy's implicit lunar challenge, designing Soyuz variants for lunar orbit and landing. They also attempted to develop the N1, a large, crewed Moon-capable launch vehicle similar to the US Saturn V.^{[ citation needed ]}

As both nations rushed to get their new spacecraft flying with men, the intensity of the competition caught up to them in early 1967, when they suffered their first crew fatalities. On January 27, the entire crew of Apollo 1, "Gus" Grissom, Ed White, and Roger Chaffee, were killed by suffocation in a fire that swept through their cabin during a ground test approximately one month before their planned launch. On April 24, the single pilot of Soyuz 1, Vladimir Komarov, was killed in a crash when his landing parachutes tangled, after a mission cut short by electrical and control system problems. Both accidents were determined to be caused by design defects in the spacecraft, which were corrected before crewed flights resumed.^{[ citation needed ]}

Approaches and Landings on Venus

On February 12, 1961, the Soviet spacecraft Venera 1 was the first flyby probe launched to another planet. However communications with the probe failed before it could complete it's mission. ^[30]

The first successful flyby Venus probe was the American Mariner 2 spacecraft, which flew past Venus in 1962, coming within 35,000 km. A modified Ranger Moon probe, it established that Venus has practically no intrinsic magnetic field and measured the temperature of the planet's atmosphere to be approximately 500 °C (773 K; 932 °F). ^[31]

Manned Lunar missions

The US conducted the first crewed spaceflight to leave Earth orbit and orbit the Moon on December 21, 1968, with the Apollo 8 space mission. Later they succeeded in achieving President Kennedy's goal on July 20, 1969, with the landing of Apollo 11. Neil Armstrong and Buzz Aldrin became the first men to set foot on the Moon. Six such successful landings were achieved through 1972, with one failure on Apollo 13.^{[ citation needed ]}

The N1 rocket suffered four catastrophic uncrewed launch failures between 1969 and 1972, and the Soviet government officially discontinued its crewed lunar program on June 24, 1974, when Valentin Glushko succeeded Korolyov as General Spacecraft Designer. ^[32]

Later phase

Move to cooperation

Apollo-Soyuz Test Project (ASTP, 1975), first docking between the two competitor states, testing shared docking systems enabling future cooperation programs away from the competition. ^[33]

Space Shuttle (US) docked to Mir (USSR/Russia) (1995), both products of the ending competition, joined in the Shuttle-Mir program (1993–1998) which facilitated the ongoing International Space Station programme.

Both nations went on to fly relatively small, non-permanent crewed space laboratories Salyut and Skylab, using their Soyuz and Apollo craft as shuttles. The US launched only one Skylab, but the USSR launched a total of seven "Salyuts", three of which were secretly Almaz military crewed reconnaissance stations, which carried "defensive" cannons. Crewed reconnaissance stations were found to be a bad idea since uncrewed satellites could do the job much more cost-effectively. The United States Air Force had planned a crewed reconnaissance station, the Manned Orbital Laboratory, which was cancelled in 1969. The Soviets cancelled Almaz in 1978.^{[ citation needed ]}

In a season of detente, the two competitors declared an end to the race and literally shook hands on July 17, 1975, with the Apollo-Soyuz Test Project, where the two craft docked, and the crews exchanged visits.

Diversification

A commemorative plaque honouring the Space Station Intergovernmental Agreement (IGA) for the International Space Station, signed on 28 January 1998 and symbolic for the increasing diversification and internationalization of spaceflight since its beginning

While participation of private actors and other countries beside the Soviet Union and the United States in spaceflight had been the case from the very start of spaceflight development. A first commercial satellite had been launched by 1962, as well as in 1965 a third country achieving orbital spaceflight. The very beginning of the space age, the launch of Sputnik was in the context of international exchange, the International Geophysical Year 1957. Also soon into the space age the international community came together starting to negotiate dedicated international law governing outer space activity.

In the 1970s the Soviet Union started to invite other countries to fly their people into space through its Intercosmos program and the United States started to include women and people of colour in its astronaut program.

First exchange between the United States and the Soviet Union was formalized in the 1962 Dryden-Blagonravov agreement, calling for cooperation on the exchange of data from weather satellites, a study of the Earth's magnetic field, and joint tracking of the NASA Echo II balloon satellite. ^[34] In 1963 President Kennedy could even interest premier Khrushchev in a joint crewed Moon landing, ^{[35] [36]} but after the assassination of Kennedy in November 1963 and Khrushchev's removal from office in October 1964, the competition between the two nations' crewed space programs heated up, and talk of cooperation became less common, due to tense relations and military implications. Only later the United States and the Soviet Union slowly started to exchange more information and engage in joint programs, particularly in the light of the development of safety standards since 1970, ^[37] producing the co-developed APAS-75 and later docking standards. Most notably this signaled the ending of the first era of the space age, the Space Race, through the Apollo-Soyuz mission which became the basis for the Shuttle-Mir program and eventually the International Space Station programme.

Such international cooperation, and international spaceflight organization was furthermore fueled by increasingly more countries achieving spaceflight capabilies and together with a by the 1980s established private spaceflight sector, both being embodied by the European Space Agency. This allowed the formation of an international and commercial post-Space Race spaceflight economy and period, with by the 1990s a public perception of space exploration and space-related technologies as being increasingly commonplace. ^[38]

This increasingly cooperative diversification persisted until competition started to rise in this diversified conditions, from the 2010s and particularly by the early 2020s.

New competition

SpaceX's Falcon Heavy reusable side boosters land in unison at Cape Canaveral Landing Zones 1 and 2 following test flight on 6 February 2018.

Starting in the 2010s the diversified spaceflight sector had become by the 2020s increasingly competitive with returning inter-national competition and cooperation barrieres, like a cooperation ban enacted in the United States on China in 2011 and later the European Space Agency banning Russia, ^[39] and increased private competition in spaceflight capabilities, enabled by the Commercial Space Launch Competitiveness Act of 2015.

Some have called it a New Space Race period, ^[40] particularly in light of China's speedy advances and other Asian countries competing in advancing their spaceflight achievements, creating an Asian Space Race. ^[41] Though international cooperation and international private spaceflight remains an integral part of the sector, but competitively diversifying commercial international contracting, such as international private human spaceflight of e.g. Axiom Space in cooperation with different countries and heavily relying on the International Space Station. Which also continued operation despite international confrontations like the Russian invasion of Ukraine, while private spaceflight, with Space-X's Starlink, became a significant element in the war and international politics.

Meanwhile, a range of new lunar spaceflight programs are being advanced especially as international programs, from the Artemis program and the China-Russian plans to establish a lunar base, to the European Space Agency pened Moon Village.

This competitive but international commercial development of the spaceflight sector has been called New Space. ^[42]

Until the 21st century, space programs of the United States were exclusively operated by government agencies. In the 21st century, several aerospace companies began efforts at developing a private space industry, with SpaceX being the most successful so far.^{[ citation needed ]}

NASA

These paragraphs are an excerpt from NASA.[ edit ]

The National Aeronautics and Space Administration (NASA /ˈnæsə/ ) is an independent agency of the U.S. federal government responsible for the civil space program, aeronautics research, and space research. Established in 1958, it succeeded the National Advisory Committee for Aeronautics (NACA) to give the U.S. space development effort a distinct civilian orientation, emphasizing peaceful applications in space science. It has since led most of America's space exploration programs, including Project Mercury, Project Gemini, the 1968–1972 Apollo Moon landing missions, the Skylab space station, and the Space Shuttle. Currently, NASA supports the International Space Station (ISS) along with the Commercial Crew Program, and oversees the development of the Orion spacecraft and the Space Launch System for the lunar Artemis program.

Project Mercury

Main article: Project Mercury

Project Mercury was the first human spaceflight program of the United States, running from 1958 through 1963. Its goal was to put a person into Earth orbit and return them safely, ideally before the Soviet Union. John Glenn became the first American to orbit the Earth on February 20, 1962, aboard the Mercury-Atlas 6. ^[43]

Project Gemini

The Gemini 8 approaches the docking collar of the Agena target vehicle.

Main article: Project Gemini

Project Gemini was NASA's second human spaceflight program. The program ran from 1961 to 1966. The program pioneered the orbital maneuvers required for space rendezvous. ^[44] Ed White became the first American to make an extravehicular activity (EVA, or "space walk"), on June 3, 1965, during Gemini 4. ^[45] Gemini 6A and 7 accomplished the first space rendezvous on December 15, 1965. ^[46] Gemini 8 achieved the first space docking with an uncrewed Agena Target Vehicle on March 16, 1966. Gemini 8 was also the first US spacecraft to experience in-space critical failure endangering the lives of the crew. ^[47]

Apollo program

Main article: Apollo program

The Apollo program was the third human spaceflight program carried out by NASA. The program's goal was to orbit and land crewed vehicles on the Moon. ^[48] The program ran from 1969 to 1972. Apollo 8 was the first human spaceflight to leave Earth orbit and orbit the Moon on December 21, 1968. ^[49] Neil Armstrong and Buzz Aldrin became the first men to set foot on the Moon during the Apollo 11 mission on July 20, 1969. ^[50]

Skylab

Main article: Skylab

The Skylab program's goal was to create the first space station of NASA. The program marked the last launch of the Saturn V rocket on May 14, 1973. Many experiments were performed on board, including unprecedented solar studies. ^[51] The longest crewed mission of the program was Skylab 4 which lasted 84 days, from November 16, 1973, to February 8, 1974. ^[52] The total mission duration was 2249 days, with Skylab finally falling from orbit over Australia on July 11, 1979. ^[53]

Space Shuttle

Main article: Space Shuttle

Although its pace slowed, space exploration continued after the end of the Space Race. The United States launched the first reusable spacecraft, the Space Shuttle, on the 20th anniversary of Gagarin's flight, April 12, 1981. On November 15, 1988, the Soviet Union duplicated this with an uncrewed flight of the only Buran-class shuttle to fly, its first and only reusable spacecraft. It was never used again after the first flight; instead, the Soviet Union continued to develop space stations using the Soyuz craft as the crew shuttle.^{[ citation needed ]}

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 July 1999 she became the first woman to command a US spacecraft.The United States continued missions to the ISS and other goals with the high-cost Shuttle system, which was retired in 2011.^{[ citation needed ]}

Soviet Union

These paragraphs are an excerpt from Soviet space program.[ edit ]

The Soviet space program ^[54] (Russian: Космическая программа СССР, romanized: Kosmicheskaya programma SSSR) was the state space program of the Soviet Union, active from 1951 until the dissolution of the Soviet Union in 1991. ^{[55] [56] [57]} Contrary to its American, European, and Chinese competitors, which had their programs run under single coordinating agencies, the Soviet space program was divided between several internally competing design bureaus led by Korolev, Kerimov, Keldysh, Yangel, Glushko, Chelomey, Makeyev, Chertok and Reshetnev. ^[58] Several of these bureaus were subordinated to the Ministry of General Machine-Building. The Soviet space program served as an important marker of claims by the Soviet Union to its superpower status. ^{[59] : 1}

Sputnik

Main article: Sputnik

The Sputnik 1 became the first artificial Earth satellite on 4 October 1957. The satellite transmitted a radio signal, but had no sensors otherwise. ^[60] Studying the Sputnik 1 allowed scientists to calculate the drag from the upper atmosphere by measuring position and speed of the satellite. ^[61] Sputnik 1 broadcast for 21 days until its batteries depleted on 4 October 1957, and the satellite finally fell from orbit on 4 January 1958. ^[62]

Luna programme

Main article: Luna programme

The Luna programme was a series of uncrewed robotic satellite launches with the goal of studying the Moon. The program ran from 1959 to 1976 and consisted of 15 successful missions, the program achieved many first achievements and collected data on the Moon's chemical composition, gravity, temperature, and radiation. Luna 2 became the first human-made object to make contact with the Moon's surface in September 1959. ^[63] Luna 3 returned the first photographs of the far side of the Moon in October 1959. ^[64]

Vostok

Vostok-2M (8A292M) in Korolyov, Moscow Oblast

Main article: Vostok programme

The Vostok Programme was the first Soviet spaceflight project to put Soviet citizens into low Earth orbit and return them safely. The programme carried out six crewed spaceflights between 1961 and 1963. The program was the first program to put humans into space, with Yuri Gagarin becoming the first man in space on April 12, 1961, aboard the Vostok 1. ^[65] Gherman Titov became the first person to stay in orbit for a full day on August 7, 1961, aboard the Vostok 2. ^[66] Valentina Tereshkova became the first woman in space on June 16, 1963, aboard the Vostok 6. ^[67]

Voskhod

Main article: Voskhod programme

The Voskhod programme began in 1964 and consisted of two crewed flights before the program was canceled by the Soyuz programme in 1966. Voskhod 1 launched on October 12, 1964, and was the first crewed spaceflight with a multi-crewed vehicle. ^[68] Alexei Leonov performed the first spacewalk aboard Voskhod 2 on March 18, 1965. ^[69]

Salyut

Main article: Salyut

The Salyut programme was the first space station program undertaken by the Soviet Union. ^[70] The goal was to carry out long-term research into the problems of living in space and a variety of astronomical, biological and Earth-resources experiments. The program ran from 1971 to 1986. Salyut 1, the first station in the program, became the world's first crewed space station. ^[71]

Soyuz programme

Main article: Soyuz programme

The Soyuz programme was initiated by the soviet space program in the 1960s and continues as the responsibility of roscosmos to this day. The program currently consists of 140 completed flights, and since the retirement of the US Space Shuttle has been the only craft to transport humans. The program's original goal was part of a program to put a cosmonaut on the Moon and later became crucial to the construction of the Mir space station.^{[ citation needed ]}

Mir

This section is an excerpt from Mir.[ edit ]

Mir seen from Space Shuttle Endeavour during STS-89 (28 January 1998)

Mir (Russian: Мир, IPA: [ˈmʲir] ; lit. 'peace' or 'world') was a space station operated in low Earth orbit from 1986 to 2001, first by the Soviet Union and later by the Russian Federation. Mir was the first modular space station and was assembled in orbit from 1986 to 1996. It had a greater mass than any previous spacecraft. At the time it was the largest artificial satellite in orbit, succeeded by the International Space Station (ISS) after Mir's orbit decayed. The station served as a microgravity research laboratory in which crews conducted experiments in biology, human biology, physics, astronomy, meteorology, and spacecraft systems with a goal of developing technologies required for permanent occupation of space.

Mir was the first continuously inhabited long-term research station in orbit and held the record for the longest continuous human presence in space at 3,644 days, until it was surpassed by the ISS on 23 October 2010. ^[72] It holds the record for the longest single human spaceflight, with Valeri Polyakov spending 437 days and 18 hours on the station between 1994 and 1995. Mir was occupied for a total of twelve and a half years out of its fifteen-year lifespan, having the capacity to support a resident crew of three, or larger crews for short visits.

Buran

These paragraphs are an excerpt from Buran programme.[ edit ]

The Buran programme (Russian: Буран, IPA: [bʊˈran] , "Snowstorm", "Blizzard"), also known as the "VKK Space Orbiter programme" (Russian: ВКК «Воздушно-Космический Корабль», lit.  'Air and Space Ship'), ^[73] was a Soviet and later Russian reusable spacecraft project that began in 1974 at the Central Aerohydrodynamic Institute in Moscow and was formally suspended in 1993. ^[74] In addition to being the designation for the whole Soviet/Russian reusable spacecraft project, Buran was also the name given to orbiter 1K, which completed one uncrewed spaceflight in 1988 and was the only Soviet reusable spacecraft to be launched into space. The Buran-class orbiters used the expendable Energia rocket as a launch vehicle.

International Space Station

The ISS seen by Space Shuttle Endeavour.

Main article: International Space Station

Recent space exploration has proceeded, to some extent in worldwide cooperation, the high point of which was the construction and operation of the International Space Station (ISS). At the same time, the international space race between smaller space powers since the end of the 20th century can be considered the foundation and expansion of markets of commercial rocket launches and space tourism.^{[ citation needed ]}

The United States continued other space exploration, including major participation with the ISS with its own modules. It also planned a set of uncrewed Mars probes, military satellites, and more. The Constellation program, began by President George W. Bush in 2005, aimed to launch the Orion spacecraft by 2018. A subsequent return to the Moon by 2020 was to be followed by crewed flights to Mars, but the program was canceled in 2010 in favor of encouraging commercial US human launch capabilities.^{[ citation needed ]}

Russia, a successor to the Soviet Union, has high potential but smaller funding. Its own space programs, some of a military nature, perform several functions. They offer a wide commercial launch service while continuing to support the ISS with several of their own modules. They also operate crewed and cargo spacecraft which continued after the US Shuttle program ended. They are developing a new multi-function Orel spacecraft for use in 2020 and have plans to perform human Moon missions as well.^{[ citation needed ]}

European Space Agency

Main article: ESA

The European Space Agency has taken the lead in commercial uncrewed launches since the introduction of the Ariane 4 in 1988 but is in competition with NASA, Russia, Sea Launch (private), China, India, and others. The ESA-designed crewed shuttle Hermes and space station Columbus were under development in the late 1980s in Europe; however, these projects were canceled, and Europe did not become the third major "space power".^{[ citation needed ]}

The European Space Agency has launched various satellites, has utilized the crewed Spacelab module aboard US shuttles, and has sent probes to comets and Mars. It also participates in ISS with its own module and the uncrewed cargo spacecraft ATV.^{[ citation needed ]}

Currently, ESA has a program for the development of an independent multi-function crewed spacecraft CSTS scheduled for completion in 2018. Further goals include an ambitious plan called the Aurora Programme, which intends to send a human mission to Mars soon after 2030. A set of various landmark missions to reach this goal are currently under consideration. The ESA has a multi-lateral partnership and plans for spacecraft and further missions with foreign participation and co-funding.

Long March 5 heavy-lifted rocket of China

Shenzhou, China's crewed spacecraft.

Since 1956 the Chinese have had a space program which was aided early on from 1957 to 1960 by the Soviets. "Dong Fang Hong I" was launched on 24 April 1970 and was the first satellite to be launched by the Chinese. With increased economy and technology strength in the following decades, especially since the early 21st century, China has made significant achievements in many aspects of space activities. It has developed a sizable family of Long March rockets, including Long March 5, the launch vehicle with the highest payload capacity in Asia since 2016 ^[update] . China launched more than 140 spaceflights between 2015 and 2020. ^[75] China is operating multiple satellite systems, including communication, Earth imaging, weather forecast, ocean monitoring. BeiDou Navigation Satellite System, the satellite navigation system developed, launched, and operated by China, is one of the four core system providers of the International Committee on Global Navigation Satellite Systems. ^[76]

The US Pentagon released a report in 2006, detailing concerns about China's growing presence in space, including its capability for military action. ^[77] In 2007 China tested a ballistic missile designed to destroy satellites in orbit, which was followed by a US demonstration of a similar capability in 2008.^{[ citation needed ]}

Chinese Lunar Exploration Program

Main article: Chinese Lunar Exploration Program

As the first step of distance outer space exploration, the Chinese Lunar Exploration Program was approved in 2004. It launched two lunar orbiters: Chang'e 1 and Chang'e 2 in 2007 and 2010 respectively. On 14 December 2013, China successfully soft-landed Chang'e 3 Moon lander and its rover Yutu on the Moon's surface, becoming the first Asian country to do so. This was followed by Chang'e 4, the first soft landing on the far side of the Moon, in 2019 and Chang'e 5, the first lunar sample return mission conducted by an Asian country, in 2020, marking the completion of the three goals (orbiting, landing, returning) of the first stage of the program. ^[75] Starting from Chang'e 6, China wants to advance it plans in making a permanent International Lunar Research Station on the Moon.

Planetary Exploration of China

Main article: Planetary Exploration of China

China began its first interplanetary exploration attempt in 2011 by sending Yinghuo-1, a Mars orbiter, in a joint mission with Russia. Yet it failed to leave Earth orbit due to the failure of the Russian launch vehicle. ^[78] As a result, the Chinese space agency then embarked on its independent Mars mission. In July 2020, China launched Tianwen-1, which included an orbiter, a lander, and a rover, on a Long March 5 rocket to Mars. Tianwen-1 was inserted into Mars orbit on 10 February 2021, followed by a successful landing and deployment of the Zhurong rover on 14 May 2021, making China the second country in the world which successfully soft-landed a fully operational spacecraft on Mars surface.^{[ citation needed ]}

SpaceX Crew-2 Dragon Endeavor approaching the ISS

SpaceX (USA)

These paragraphs are an excerpt from SpaceX.[ edit ]

Space Exploration Technologies Corp., commonly referred to as SpaceX, is an American space technology company headquartered at the SpaceX Starbase near Brownsville, Texas. Since its founding in 2001, the company has made numerous advancements in rocket propulsion, reusable launch vehicle, human spaceflight and satellite constellation technology. By the late 2010s, SpaceX had become the world's dominant space launch provider, its launch cadence rivaling that of the Chinese space program ^[88] and eclipsing all those of its private competitors. ^[89] SpaceX, NASA and the United States Armed Forces work closely together by means of governmental contracts. ^[90]

SpaceX was founded by Elon Musk in 2001 with a vision of decreasing the costs of space launches, paving the way to a sustainable colony on Mars. In 2008, when SpaceX was almost bankrupt, Falcon 1 successfully launched into orbit after three failed launch attempts. The company then pivoted towards the development of the larger Falcon 9 rocket and the Dragon 1 capsule to satisfy NASA's COTS contracts for deliveries to the International Space Station. By 2012, SpaceX finished all COTS test flights and began delivering Commercial Resupply Services missions to the International Space Station. Also around that time, SpaceX started developing hardware to make the Falcon 9 first stage reusable. The company demonstrated the first successful first-stage landing in 2015 and re-launch of the first stage in 2017. Falcon Heavy, built from three Falcon 9 boosters, first flew in 2018 after a more than decade-long development process. As of October 2024, the company's Falcon 9 rockets have landed and flown again more than 330 times, reaching 1-2 launches a week.

SpaceX is also planning a fully reusable rocket named Starship. It consists of a first stage named Super Heavy and a second stage also named Starship.

Blue Origin
