Shenzhou program

The Shenzhou program (/ˈʃɛnˈ/,[1] Chinese: , see § Etymology) is a crewed spaceflight initiative by People's Republic of China. The program put the first Chinese citizen, Yang Liwei, into orbit on 15 October 2003.

The development began in 1992, under the name of Project 921-1. The Chinese National Manned Space Program was given the designation Project 921 with Project 921-1 as its first significant goal. The plan called for a crewed launch in October 1999, prior to the new millennium.[citation needed]

Russian assistance to the program began as early as May 1991, when Russian lecturers briefed the Chinese engineers on the capabilities and potential of their Soyuz spacecraft.[2] This was followed by two-year fellowships for 20 young Chinese engineers in Russia during 1992–1994. In September 1994, Chinese Communist Party (CCP) general secretary Jiang Zemin visited the Russian Flight Control Centre in Kaliningrad and noted that there were broad prospects for co-operation between the two countries in space. In March 1995, a deal was signed to transfer manned spacecraft technology to China,[3][4] Included in the agreement were training of cosmonauts, provision of Soyuz spacecraft capsules and life support systems, androgynous docking systems, and space suits.

The first four uncrewed test flights happened in 1999, 2001, and 2002. These were followed by crewed missions. Shenzhou missions are launched on the Long March 2F from the Jiuquan Satellite Launch Center. The command center of the mission is the Beijing Aerospace Command and Control Center. The China Manned Space Engineering Office provides engineering and administrative support for the crewed Shenzhou missions.[5]

The name Shenzhou is translated as Divine vessel.[6]


China's first efforts at human spaceflight started in 1968 with a projected launch date of 1973. Although China did launch an uncrewed satellite in 1970 and has maintained an active uncrewed program since, the crewed spaceflight program was cancelled due to lack of funds and political interest. Instead, China decided in 1978 to pursue a method of sending astronauts into space using the more familiar FSWderived ballistic reentry capsules. Two years later. in 1980, the Chinese government cancelled the program citing cost concerns.[7]

The current Chinese human spaceflight program was authorized on September 21 1992 by the Standing Committee of Politburo as Project 921–1, with work beginning on 1 January 1993. The initial plan has three phases:[8]

  • Phase 1 would involve launch of two uncrewed versions of the crewed spacecraft, followed by the first Chinese crewed spaceflight, by 2002.
  • Phase 2 would run through 2007, and involve a series of flights to prove the technology, conduct rendezvous and docking operations in orbit, and operate an 8-ton spacelab using the basic spacecraft technology.
  • Phase 3 would involve orbiting of a 20-ton space station in the 2010–2015 period, with crews being shuttled to it using the 8-ton crewed spacecraft.

The chief designers include Qi Faren and Wang Yongzhi. The first uncrewed flight of the spacecraft was launched on 19 November 1999, after which Project 921-1 was renamed Shenzhou, a name reportedly chosen by CCP General Secretary Jiang Zemin. A series of three additional uncrewed flights ensued. The Shenzhou reentry capsules used are 13% larger than Soyuz reentry capsules, and it is expected that later craft will be designed to carry a crew of four instead of Soyuz's three, although physical limitations on astronaut size, as experienced with earlier incarnations of Soyuz, will likely apply.[citation needed]

The fifth launch, Shenzhou 5, was the first to carry a human (Yang Liwei) and occurred at 01:00:00 UTC on 15 October 2003.[9]

Like similar space programs in other nations, Shenzhou has raised some questions about whether China should spend money on launching people into space, arguing that these resources would be better directed elsewhere. Indeed, two earlier human spaceflight programs, one in the mid-1970s and the other in the 1980s, were cancelled because of expense. In response, several justifications have been offered in the Chinese media. One is that the long-term destiny of humanity lies in the exploration of space, and that China should not be left behind. Another is that such a program will catalyze the development of science and technology in China. Finally, it has been argued that the prestige resulting from this capability will increase China's stature in the world, in a similar manner to the 2008 Olympics.[citation needed]

On 17 October 2005, following the success of Shenzhou 6, Chinese media officially stated that the cost of this flight was around US$110 million, and the gross cost of Project 921/1 in the past 11 years was US$2.3 billion (about $3.2 billion in 2020 value). These values are lower than the cost of similar space programs in other nations,[citation needed] but higher than the development cost of the SpaceX's Dragon Crew, with about $3.1 billion.[10]

The Chinese media has heavily promoted the experiments undertaken by Shenzhou, particularly exposing seeds, including some from Taiwan, to zero gravity and radiation. Most scientists, however, discount the usefulness of this type of experiment.[citation needed]

The experience during the 1960s of both the United States with the Manned Orbiting Laboratory and the Soviet Union with the Almaz space station suggests that the military usefulness of human spaceflight is quite limited and that practically all military uses of space are much more effectively performed by uncrewed satellites. Thus while the Shenzhou orbital module could be used for military reconnaissance, there appears to be no military reason for incorporating such a system in a crewed mission, as China could use purely uncrewed satellites for these purposes.[citation needed]


Today, china uses Shenzhou spacecraft to perform crewed missions. The Shenzhou spacecraft resembles the Soviet Union's Soyuz, although it is larger. Unlike the Soyuz, it features a powered orbital module capable of autonomous flight.

Like Soyuz, Shenzhou consists of three modules: a forward orbital module (轨道舱), a reentry capsule (返回舱) in the middle, and an aft service module (推进舱). This division is based on the principle of minimizing the amount of material to be returned to Earth. Anything placed in the orbital or service modules does not require heat shielding, and this greatly increases the space available in the spacecraft without increasing weight as much as it would need to be if those modules needed to withstand reentry.
