Chinese space program


The space program of the People's Republic of China is directed by the China National Space Administration. Its technological roots can be traced back to the late 1950s, when China began a ballistic missile program in response to perceived American threats. However, the first Chinese crewed space program only began several decades later, when an accelerated program of technological development culminated in Yang Liwei's successful 2003 flight aboard Shenzhou 5. This achievement made China the third country to independently send humans into space. Plans currently include a permanent Chinese space station in 2022 and crewed expeditions to the Moon.
Officials have articulated long term ambitions to exploit Earth-Moon space for industrial development.

History

After the United States threatened to use nuclear weapons during the Korean War, Chairman Mao Zedong decided that only a nuclear deterrent of its own would guarantee the security of the newly founded PRC. Additionally, he wanted China to gain status among the world's powers that—as he felt—did not respect him. From this, he decided instead to only implement his new plan with the Republic of China as "China". Thus, Mao announced his decision to develop China's own strategic weapons, including nuclear bombs and associated missiles for the warheads, during a Communist Party of China Central Committee meeting held on January 15, 1955. The Chinese nuclear weapons program was designated by the codename of "02".
The Fifth Academy of the National Defense Ministry was founded on October 8, 1956, with Qian Xuesen, who had just been deported from the United States after being accused of being a communist during the red scare, as director. The Academy started the development of the first ballistic missile program, adopted on March 1, 1956 and known as the first Twelve-Year-Plan for Chinese aerospace.
After the launch of mankind's first artificial satellite, Sputnik 1, by the Soviet Union on October 4, 1957, Mao decided during the National Congress of the CPC on May 17, 1958 to make China an equal with the superpowers , by adopting Project 581 with the objective of placing a satellite in orbit by 1959 to celebrate the 10th anniversary of the PRC's founding.
This goal would be achieved in three phases: developing sounding rockets first, then launching small satellites and in the final phase, large satellites.
During the cordial Sino-Soviet relations of the 1950s, the USSR engaged in a cooperative technology transfer program with the PRC under which they trained Chinese students and provided the fledgling program with a sample R-2 rocket. But when Soviet premier Nikita Khrushchev was denounced as revisionist, with Mao asserting that there had been a counter-revolution in the Soviet Union and that capitalism had been restored, the friendly relationship between the two countries turned to confrontation. As a consequence, all Soviet technological assistance was abruptly withdrawn after the 1960 Sino-Soviet split.
Only 17 days after the last Soviet expert had left China, the first Soviet built R-2 rocket fueled with Chinese-made propellant was launched with success on September 10, 1960. Due to Cold War tension, Mao decided in December 1963 that China should develop missile defence system capacity. During a conference held on February 2, 1964, directive 640 was adopted .
  • The first successful launch of a Chinese 1059 SRBM missile copy of the R-2 was conducted only two months later on November 5, 1960. The missile was also designated DF-1. The first DF-2 MRBM was tested on March 21, 1962, but failed.
  • Development eventually continued with the redesigned DF-2A MRBM which was successfully tested on June 29, 1964. It would enter service by the end of 1966.
  • The first successful launch and recovery of a T-7A sounding rocket carrying a biological experiment was on July 19, 1964 from Base 603 program in August 1965. It was designed to carry a single nuclear warhead and has a maximum range of 12000 km. In November 1966, it was decided to build a second ballistic missile test site, the Northern Missile Test Site ) in Shanxi Province, farther away from China's northern border.
  • On October 27, 1966, a nuclear-tipped DF-2A missile was launched from Jiuquan and the 20 kilotons yield nuclear warhead exploded at the height of 569 meters over the target in Lop Nor or Base 21 situated 894 km away.
  • On December 26, 1966, China tested its first indigenously developed DF-3 intermediate-range ballistic missile with success. The DF-3 was a single-stage, single-warhead missile with a maximum range of 2500 km. The development of the DF-4 IRBM began in 1967 in parallel with the single-stage DF-3.
  • In March 1967, development started on the JL-1 submarine-launched ballistic missile to accompany the Type 092 ballistic missile submarine also in development.

As the space race between the two superpowers reached its climax with the conquest of the Moon, Mao and Zhou Enlai decided on July 14, 1967 that the PRC should not be left behind, and started China's own crewed space program.
After Mao died on September 9, 1976, his rival, Deng Xiaoping, denounced during the Cultural Revolution as reactionary and therefore forced to retire from all his offices, slowly re-emerged as China's new leader in 1978. At first, new development was slowed. Then, several key projects deemed unnecessary were simply cancelled—the Fanji ABM system, the Xianfeng Anti-Missile Super Gun, the ICBM Early Warning Network 7010 Tracking Radar and the land-based high-power anti-missile laser program. Nevertheless, some development did proceed.
Along Deng's policy of capitalist reforms in the Chinese economy, Chinese culture also changed. Therefore, names used in the space program, previously all chosen from the revolutionary history of the PRC, were soon replaced with mystical-religious ones. Thus, new Long March carrier rockets were renamed Divine arrow, spacecraft Divine vessel, space plane Divine dragon, land-based high-power laser Divine light and supercomputer Divine might''.
China has since turned its focus to extraterrestrial exploration starting with the Moon. The first Chinese Lunar Exploration Program un-crewed lunar orbiter Chang'e 1 was successfully launched on October 24, 2007, making China the fifth nation to successfully orbit the Moon.

Chinese space program and the international community

Dual-use technologies and outer space

The PRC is a member of the United Nations Committee on the Peaceful Uses of Outer Space and a signatory to all United Nations treaties and conventions on space, with the exception of the 1979 Moon Treaty. The United States government has long been resistant to the use of PRC launch services by American industry due to concerns over alleged civilian technology transfer that could have dual-use military applications to countries such as North Korea, Iran or Syria, and announced an official embargo against the PRC in 2000. Thus, financial retaliatory measures have been taken on many occasions against several Chinese space companies.

Chinese exclusion policy of NASA

Due to security concerns, all researchers from the U.S. National Aeronautics and Space Administration are prohibited from working with Chinese citizens affiliated with a Chinese state enterprise or entity. In April 2011, the 112th United States Congress banned NASA from using its funds to host Chinese visitors at NASA facilities. In March 2013, the U.S. Congress passed legislation barring Chinese nationals from entering NASA facilities without a waiver from NASA.
The history of the U.S. exclusion policy can be traced back in 1998 when a U.S. Congressional Commission led by Christopher Cox discovered that the technical information that American companies provided China for its commercial satellite ended up improving Chinese intercontinental ballistic missile technology. This was further aggravated in 2007 when China blew up a defunct meteorological satellite in low Earth orbit to test a ground-based anti-satellite missile. The debris created by the explosion contributed to the space junk that litter Earth's orbit, exposing American military space assets at the risk such as accidental collision. The United States also fears the Chinese application of dual-use space technology for nefarious purposes. The U.S. imposed an embargo to the U.S. - China space cooperation throughout the 2000s and by 2011, a clause inserted by then-Congressman Frank Wolf in the 2011 U.S. federal budget forbids NASA from hosting or participating in a joint scientific activity with China.
The Chinese response to the exclusion policy involved its own space policy of opening up its space station to the outside world, welcoming scientists coming from all countries. American scientists have also boycotted NASA conferences due to its rejection of Chinese nationals in these events.

Organization

Initially the space program of the PRC was organized under the People's Liberation Army, particularly the Second Artillery Corps. In the 1990s, the PRC reorganized the space program as part of a general reorganization of the defense industry to make it resemble Western defense procurement.
The China National Space Administration, an agency within the Commission of Science, Technology and Industry for National Defense currently headed by Zhang Kejian, is now responsible for launches. The Long March rocket is produced by the China Academy of Launch Vehicle Technology, and satellites are produced by the China Aerospace Science and Technology Corporation. The latter organizations are state-owned enterprises; however, it is the intent of the PRC government that they should not be actively state-managed and that they should behave much as private companies would in the West.

Universities and institutes

The space program also has close links with:
The PRC operates 4 satellite launch centers:
Plus shared space tracking facilities with France, Brazil, Sweden and Australia.

Crewed landing sites

Project 714

As the Space Race between the two superpowers reached its climax with humans landing on the Moon, Mao Zedong and Zhou Enlai decided on July 14, 1967 that the PRC should not be left behind, and therefore initiated China's own crewed space program. The top-secret Project 714 aimed to put two people into space by 1973 with the Shuguang spacecraft. Nineteen PLAAF pilots were selected for this goal on 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 cancelled on May 13, 1972 for economic reasons, though the internal politics of the Cultural Revolution likely motivated the closure.
The short-lived second crewed program was based on the successful implementation of landing technology by FSW satellites. It was announced a few times in 1978 with the open publishing of some details including photos, but then was abruptly canceled in 1980. It has been argued that the second crewed program was created solely for propaganda purposes, and was never intended to produce results.

Project 863

A new crewed space program was proposed by the Chinese Academy of Sciences in March 1986, as Astronautics plan 863-2. This consisted of a crewed spacecraft used to ferry astronaut crews to a space station. In September of that year, astronauts in training were presented by the Chinese media. The various proposed crewed spacecraft were mostly spaceplanes. Project 863 ultimately evolved into the 1992 Project 921.

Project 921 (Shenzhou)

Spacecraft

In 1992, authorization and funding was given for the first phase of Project 921, which was a plan to launch a crewed spacecraft. The Shenzhou program had four uncrewed test flights and two crewed missions. The first one was Shenzhou 1 on November 20, 1999. On January 9, 2001 Shenzhou 2 launched carrying test animals. Shenzhou 3 and Shenzhou 4 were launched in 2002, carrying test dummies. Following these was the successful Shenzhou 5, China's first crewed mission in space on October 15, 2003, which carried Yang Liwei in orbit for 21 hours and made China the third nation to launch a human into orbit. Shenzhou 6 followed two years later ending the first phase of the Project 921. Missions are launched on the Long March 2F rocket from the Jiuquan Satellite Launch Center. The China Crewed Space Engineering Office provides engineering and administrative support for the crewed Shenzhou missions.

Space laboratory

The second phase of the Project 921 started with Shenzhou 7, China's first spacewalk mission. Then, two crewed missions were planned to the first Chinese space laboratory. The PRC initially designed the Shenzhou spacecraft with docking technologies imported from Russia, therefore compatible with the International Space Station. On September 29, 2011, China launched Tiangong 1. This target module is intended to be the first step to testing the technology required for a planned space station.
On October 31, 2011, a Long March 2F rocket lifted the Shenzhou 8 uncrewed spacecraft which docked twice with the Tiangong 1 module. The Shenzhou 9 craft took off on 16 June 2012 with a crew of 3. It successfully docked with the Tiangong-1 laboratory on 18 June 2012, at 06:07 UTC, marking China's first crewed spacecraft docking. Another crewed mission, Shenzhou 10, launched on 11 June 2013. The Tiangong 1 target module is then expected to be deorbited.
A second space lab, Tiangong 2, launched on 15 September 2016, 22:04:09. The launch mass was 8,600 kg, with a length of 10.4m and a width of 3.35m, much like the Tiangong 1. Shenzhou 11 launched and rendezvoused with Tiangong 2 in October 2016, with an unconfirmed further mission Shenzhou 12 in the future. The Tiangong 2 brings with it the POLAR gamma ray burst detector, a space-Earth quantum key distribution and laser communications experiment to be used in conjunction with the Mozi 'Quantum Science Satellite', a liquid bridge thermocapillary convection experiment and a space material experiment. Also included is a stereoscopic microwave altimeter, a space plant growth experiment, and a multi-angle wide-spectral imager and multi-spectral limb imaging spectrometer. Onboard TG-2 there will also be the world's first-ever in-space cold atomic fountain clock.

Space station

A larger basic permanent space station would be the third and last phase of Project 921. This will be a modular design with an eventual weight of around 60 tons, to be completed sometime before 2022. The first section, designated Tiangong 3, is scheduled for launch after Tiangong 2. Tiangong 3 will weigh 22 tons and be 18.1 metres long. Additional modules will be connected over several missions to build the space station.
This could also be the beginning of China's crewed international cooperation, the existence of which was officially disclosed for the first time after the launch of Shenzhou 7.
The Chinese space station is scheduled to be completed in 2022.

Lunar exploration

In February 2004, the PRC formally started the implementation phase of its uncrewed Moon exploration project. According to Sun Laiyan, administrator of the China National Space Administration, the project will involve three phases: orbiting the Moon; landing; and returning samples. The first phase planned to spend 1.4 billion renminbi to orbit a satellite around the Moon before 2007, which is ongoing. Phase two involves sending a lander before 2010. Phase three involves collecting lunar soil samples before 2020.
On November 27, 2005, the deputy commander of the crewed spaceflight program announced that the PRC planned to complete a space station and a crewed mission to the Moon by 2020, assuming funding was approved by the government.
On December 14, 2005, it was reported "an effort to launch lunar orbiting satellites will be supplanted in 2007 by a program aimed at accomplishing an uncrewed lunar landing. A program to return uncrewed space vehicles from the moon will begin in 2012 and last for five years, until the crewed program gets underway" in 2017, with a crewed Moon landing some time after that.
Nonetheless, the decision to develop a totally new Moon rocket in the 1962 Soviet UR-700M-class able to launch a 500-ton payload in LTO and a more modest 50 tons LTO payload LV has been discussed in a 2006 conference by academician Zhang Guitian, a liquid propellant rocket engine specialist, who developed the CZ-2 and CZ-4A rockets engines.
On June 22, 2006, Long Lehao, deputy chief architect of the lunar probe project, laid out a schedule for China's lunar exploration. He set 2024 as the date of China's first moonwalk.
In September 2010, it was announced that the country is planning to carry out explorations in deep space by sending a man to the Moon by 2025. China also hopes to bring a Moon rock sample back to Earth in 2017, and subsequently build an observatory on the Moon's surface. Ye Peijian, Commander in Chief of the Chang'e programme and an academic at the Chinese Academy of Sciences, added that China has the "full capacity to accomplish Mars exploration by 2013."
On December 14, 2013 China's Chang'e 3 became the first object to soft-land on the Moon since Luna 24 in 1976.
On January 3, 2019, Chang'e 4, the China National Space Administration's lunar rover, successfully landed on the far side of the Moon. The rover was able to transmit data back to Earth despite the lack of radio frequencies on the far side, via a dedicated satellite sent earlier to orbit the moon. The landing and data transmission is considered a landmark achievement for human space exploration.
As indicated by the official Chinese Lunar Exploration Program insignia, denoted by a calligraphic Moon ideogram in the shape of a nascent lunar crescent, with two human footsteps at its center, the ultimate objective of the program is to establish a permanent human presence on the Earth's natural satellite.
Yang Liwei declared at the 16th Human in Space Symposium of International Academy of Astronautics in Beijing, on May 22, 2007 that building a lunar base was a crucial step to realize a flight to Mars and farther planets.
According to practice, since the whole project is only at a very early preparatory research phase, no official crewed Moon program has been announced yet by the authorities. But its existence is nonetheless revealed by regular intentional leaks in the media. A typical example is the Lunar Roving Vehicle that was shown on a Chinese TV channel during the 2008 May Day celebrations.

Mission to Mars and beyond

, administrator of the China National Space Administration, said on July 20, 2006 that China would start deep space exploration focusing on Mars over the next five years, during the Eleventh Five-Year Plan Program period.
The first uncrewed Mars exploration program could take place sometime between around 2033, followed by a crewed phase in 2040-2060. The Mars 500 study of 2011 prepared for this crewed mission.
Moreover, in order to make crewed flight in deep space toward Mars safer, a space weather forecast system was to be completed by 2017 with the Kuafu mission satellites placed at the Lagrangian Point L1. However, due to withdrawal first by Canada and then ESA, the project was indefinitely postponed.
In 2006, the Chief Designer of the Shenzhou spacecraft stated in an interview that:

Space-based solar power

According to the China Academy of Space Technology presentation at the 2015 International Space Development Congress in Toronto, Canada, Chinese interest in space-based solar power began in the period 1990–1995. By 2011 there was a proposal for a national program, with advocates such as Pioneer Professor Wang Xiji stating in an article for the Ministry of Science and technology that "China had built up a solid industrial foundation, acquired sufficient technology and had enough money to carry out the most ambitious space project in history. Once completed, the solar station, with a capacity of 100MW, would span at least one square kilometre, dwarfing the International Space Station and becoming the biggest man-made object in space" and "warned that if it did not act quickly, China would let other countries, in particular the US and Japan, take the lead and occupy strategically important locations in space." Global Security cites a 2011-01 Journal of Rocket propulsion that articulates the need for 620+ launches of their Long March-9 heavy lift system for the construction of an orbital solar power plant with 10,000 MW capacity massing 50,000 tonnes.

By 2013 there was a national goal, that "the state has decided that power coming from outside of the earth, such as solar power and development of other space energy resources, is to be China's future direction" and the following roadmap was identified: "In 2010, CAST will finish the concept design; in 2020, we will finish the industrial level testing of in-orbit construction and wireless transmissions. In 2025, we will complete the first 100kW SPS demonstration at LEO; and in 2035, the 100MW SPS will have electric generating capacity. Finally in 2050, the first commercial level SPS system will be in operation at GEO." The article went on to state that "Since SPS development will be a huge project, it will be considered the equivalent of an Apollo program for energy. In the last century, America's leading position in science and technology worldwide was inextricably linked with technological advances associated with implementation of the Apollo program. Likewise, as China's current achievements in aerospace technology are built upon with its successive generations of satellite projects in space, China will use its capabilities in space science to assure sustainable development of energy from space."
In 2015, the CAST team won the International SunSat Design Competition with their video of a Multi-Rotary Joint concept. The design was presented in detail in a paper for the Online Journal of Space Communication.
In 2016, Lt Gen. Zhang Yulin, deputy chief of the armament development department of the Central Military Commission, suggested that China would next begin to exploit Earth-Moon space for industrial development. The goal would be the construction of space-based solar power satellites that would beam energy back to Earth.

Goals

The China National Space Administration stated that their long-term goals are:

Launch vehicles

Crewed LEO Program

China's first deep space probe, the Yinghuo-1 orbiter, was launched in November 2011 along with the joint Fobos-Grunt mission with Russia, but the rocket failed to leave Earth orbit and both probes underwent destructive re-entry on 15 January 2012.
In 2018, Chinese researchers proposed a deep space exploration roadmap to explore Mars, an asteroid, Jupiter, and further targets, within the 2020–2030 timeframe.
Proposed and upcoming robotic missions include:
These missions, with the exception of the Uranus mission, have been officially approved or are in the study phase as of June 2017.

Research

The Center for Space Science and Applied Research, was founded in 1987 by merging the former Institute of Space Physics and the Center for Space Science and Technology. The research fields of CSSAR mainly cover 1. Space Engineering Technology; 2. Space Weather Exploration, Research, and Forecasting; 3. Microwave Remote Sensing and Information Technology.
