Chinese space program

• 1. Origins And Early Development

  ›

  In 1955, a rocketry scientist named Qian Xuesen returned to China from the United States. He brought with him decades of experience that would become the foundation for a new national program. By the 8th of October 1956, the Fifth Research Academy under the Ministry of National Defense was established with fewer than 200 staff members recruited by Qian. This small group began work on missile technology in response to Cold War tensions and perceived threats from both American and Soviet superpowers.

  The early years were defined by rapid adaptation after external support vanished. In December 1957, two Soviet R-2 missiles arrived secretly as part of a cooperative transfer agreement. Chinese engineers produced a licensed copy designated "1059" with an initial target launch date of 1959. Political shifts soon altered this timeline when the Sino-Soviet split caused Moscow to withdraw all technical assistance abruptly.

  Despite these challenges, the team achieved its first indigenous success on the 19th of February 1960. A sounding rocket called T-7M reached an altitude of 8 kilometers during a test flight. Mao Zedong praised the achievement as a good beginning for independent development. The following year, on the 5th of December 1960, the "missile 1059" successfully launched using alcohol and liquid oxygen fuel. It marked China's ability to replicate Soviet designs without direct guidance.

  By the 29th of June 1964, the Dongfeng-2 missile achieved its first successful launch at Jiuquan Satellite Launch Center. This was the first weapon designed and built entirely by Chinese engineers. Over the next few years, seven additional launches of the improved Dongfeng-2A variant ended in success. On the 27th of October 1966, one such missile detonated a nuclear warhead over a target area as part of the "Two Bombs, One Satellite" project.

  The program expanded rapidly through the Third Front campaign which relocated critical infrastructure to remote interior regions. New facilities included Xichang Satellite Launch Center and Taiyuan Satellite Launch Center. These sites were established to protect against potential invasions while developing carrier rockets capable of placing satellites into orbit.

• 2. Commercial Launch Era And Setbacks

  ›

  In January 1989, China signed its first commercial contract with AsiaSat to launch a Hughes-built communications satellite. The mission succeeded on the 7th of April 1990 when a Long March 3 rocket placed AsiaSat 1 into geosynchronous transfer orbit with high precision. This victory introduced the world to Chinese commercial launch capabilities during a decade of international cooperation.

  However, technical limitations soon emerged. The original Long March 3 could only carry payloads up to 1,500 kilograms into orbit. New generation communication satellites often exceeded 2,500 kilograms requiring heavier lift capacity. To address this gap, engineers developed the Long March 2E rocket featuring strap-on boosters capable of delivering 3,000 kilograms to geostationary transfer orbit.

  Development began in November 1988 after China Aerospace Corporation won a contract for two Optus satellites from Hughes. Engineers built all hardware from scratch within an 18-month period that impressed American experts. A test flight carrying an Optus mass simulator reached its intended orbit on the 16th of September 1990. Yet disaster struck less than five months later during the actual launch attempt.

  On the 22nd of March 1992, at Xichang Satellite Launch Center, all engines shut down unexpectedly after initial ignition. Minor aluminum scraps had caused a control circuit shortage triggering an emergency shutdown. The rocket failed to lift off while being live-streamed globally. Despite the abort, the payload and launch facilities remained intact thanks to a 39-hour rescue operation.

  A new Long March 2E successfully launched the Optus satellite on the 14th of August 1992. But further setbacks followed. On the 15th of February 1996, a Long March 3B rocket carrying Intelsat 708 veered off course immediately after clearing the platform. It crashed 22 seconds later killing six people and injuring 57 others. This became the most disastrous event in Chinese space program history.

  Another failure occurred on August 18 when ChinaSat 7 suffered a third-stage re-ignition malfunction. These consecutive failures led to canceled orders and refusal of insurance from international clients. In response, China established a closed-loop quality management system that dramatically improved success rates. From the 20th of October 1996 through the 16th of August 2011, the nation achieved 102 consecutive successful launches.

  On the 20th of November 1999, Shenzhou-1 lifted off from Jiuquan Satellite Launch Center aboard a Long March 2F rocket. The uncrewed spacecraft orbited Earth for 14 rounds before returning safely to Inner Mongolia early the next morning. This mission validated all systems required for human spaceflight and marked the formal public announcement of the China Manned Space Program.

  Project 921 had been approved by the CCP Politburo Standing Committee on the 21st of September 1992 with three ambitious goals: crewed spacecraft launch and return, short-term space laboratory missions, and long-term modular space station construction. Fourteen candidates were selected to form the People's Liberation Army Astronaut Corps beginning their training immediately.

  Three uncrewed test flights occurred between January 2001 and January 2003. Shenzhou-4 launched on the 30th of December 2002 flew for six days and 18 hours orbiting Earth 108 times before returning on the 5th of January 2003. This final rehearsal confirmed readiness for human occupancy.

  The historic moment arrived on the 15th of October 2003 when Yang Liwei became the first Chinese person in space aboard Shenzhou-5. After more than 21 hours and 14 orbits around Earth, the spacecraft landed safely in Inner Mongolia. Yang walked out of the capsule alone marking a complete success celebrated worldwide including endorsements from UN Secretary General Kofi Annan.

  Subsequent missions expanded capabilities significantly. Fei Junlong and Nie Haisheng completed China's first multi-person multi-day flight aboard Shenzhou-6 between October 12 and 17, 2005. On the 25th of September 2008, Zhai Zhigang conducted the nation's first spacewalk alongside Liu Boming during the Shenzhou-7 mission.

  Tiangong-1 served as a prototype space station launched in 2011. It docked automatically with uncrewed Shenzhou-8 on the 3rd of November 2011 verifying rendezvous procedures. Manual docking followed in June 2012 when Shenzhou-9 carried Jing Haipeng, Liu Wang, and China's first female astronaut Liu Yang to the module.

  Tiangong-2 launched on the 15th of September 2016 represented China's first true space laboratory. Jing Haipeng and Chen Dong stayed aboard for approximately 30 days breaking previous duration records while conducting experiments. In April 2017, Tianzhou-1 became the first cargo spacecraft to dock with Tiangong-2 completing multiple propellant refueling tests.

  On the 24th of October 2007, Chang'e-1 lifted off from Xichang Satellite Launch Center aboard a Long March 3A rocket. The orbiter entered lunar orbit on November 7 becoming China's first artificial satellite of the Moon. It produced the nation's first lunar map before performing a controlled hard landing on the 1st of March 2009 concluding its mission.

  Chang'e-2 launched on the 1st of October 2010 used trans-lunar injection to reach the Moon for the first time. It imaged the Sinus Iridum region where future landings were expected. On the 2nd of December 2013, a Long March 3B rocket delivered Chang'e-3 to the lunar surface. The lander touched down in the Sinus Iridum region making China the third country to achieve soft landing on an extraterrestrial body.

  The Yutu rover deployed onto the surface the following day starting surveys achieving the "landing and roving" phase goals. Despite this success, interplanetary ambitions faced setbacks. Yinghuo-1, China's first Mars orbiter launched aboard Russian Fobos-Grunt in November 2011 failed when the probe stranded in low Earth orbit burning up two months later.

  Chang'e-4 made history on the 3rd of January 2019 by soft-landing at the Von Kármán crater on the far side of the Moon. Communications challenges required launching Queqiao relay satellite in May 2018 to orbit around the Earth-Moon L2 Lagrangian point enabling contact with the far side. A rover named Yutu-2 deployed hours after landing conducting the first trial on the lunar far side.

  Chang'e-5 returned samples from the Moon on the 17th of December 2020 after launching on the 24th of November 2020. The spacecraft landed near Mons Rümker in Oceanus Procellarum collecting 1,731 grams of material. On December 3, the ascent vehicle lifted off from the lunar surface carrying samples back to lunar orbit where it docked with the orbiter completing the first automated rendezvous and docking in lunar orbit history.

  The return capsule landed intact in Inner Mongolia sealing completion of the "Orbiting Landing Returning" plan. Chang'e-6 followed this achievement by returning samples from the Apollo Basin on the far side of the Moon on the 25th of June 2024.

  On the 23rd of July 2020, Tianwen-1 launched aboard a Long March 5 rocket into trans-Mars injection orbit. The mission aimed to achieve orbiting landing and roving on Mars during its single attempt. After seven months traveling 400 million kilometers, the spacecraft entered Mars orbit on the 10th of February 2021 becoming China's first operational Mars probe.

  The lander successfully touched down on the 15th of May 2021 at 7:18 am Beijing time in Utopia Planitia following nine minutes of atmospheric entry. Zhurong rover drove onto the Martian surface the next day marking China as the second nation to land and drive a Mars rover after the United States. High-resolution images released on June 11 confirmed successful operations.

  Tianwen-1 received the IAF World Space Award of 2022 recognizing its ambitious nature and inspiring success. This marked the second time a Chinese team earned this honor following Chang'e-4 in 2019.

  Further deep space efforts included attempts to launch DRO-A and DRO-B spacecraft into distant retrograde orbits around the Moon on the 13th of March 2024. These missions failed to reach their target due to upper stage malfunctions leaving them stranded in low Earth orbit despite rescue attempts raising their orbits significantly.

  Queqiao-2 relay satellite launched on the 20th of March 2024 along with two mini satellites Tiandu 1 and 2 entered lunar orbit successfully. They will provide communications for future Chang'e missions including Chang'e-6 Chang'e-7 and Chang'e-8 targeting both the far side and south pole regions.

  Chang'e-6 returned samples from the Apollo Basin on the far side of the Moon on the 25th of June 2024 completing another robotic rendezvous and docking in lunar orbit. The orbiter was captured by the Sun-Earth L2 Lagrange point on the 9th of September 2024 after dropping off return samples.

  For decades the Long March family relied on dinitrogen tetroxide and UDMH propellants offering simplicity but suffering from toxicity environmental damage and low specific impulse. Engineers began studying alternatives since Project 863 introduced new selection criteria in 1986.

  A 120-ton rocket engine burning liquid oxygen and kerosene in staged combustion cycle received formal approval in 2000. Development faced setbacks including explosions during initial firing tests yet breakthroughs occurred in superalloy production and ignition systems achieving first long duration firing test in 2006. The YF-100 engine certified in 2012 became ready for actual flight in 2014.

  Long March 6 launched successfully on the 20th of September 2015 using one YF-100 engine on its first stage. Medium-lift Long March 7 completed its maiden flight on the 25th of June 2016 equipped with six YF-100 engines increasing maximum low Earth orbit payload capacity to 13.5 tons. These successes signaled introduction of clean efficient next-generation rockets powered by LOX/kerosene combinations.

  Wenchang Space Launch Site opened for operations with the Long March 7 launch marking inauguration on the world stage. Construction began in September 2009 taking advantage of low latitude allowing ten to fifteen percent more payload mass compared to inland sites like Jiuquan Taiyuan or Xichang. Coastal location enabled ocean drop zones eliminating ground threats while permitting delivery of larger rockets via sea transport bypassing tunnel size limits.

  The Long March 5 represented China's most powerful rocket capable of lifting up to 25 tons to low Earth orbit and 14 tons to geostationary transfer orbit. Its 57-meter height featured a 5-meter diameter core stage burning liquid hydrogen/liquid oxygen alongside four 3.35-meter side boosters burning kerosene/LOX. Total launch mass reached 869 metric tons generating 10,573 kilonewtons lift-off thrust making it comparable to Delta IV Heavy at that time.

  A failure during second launch on the 2nd of July 2017 grounded the vehicle indefinitely until resolution allowed return-to-flight mission on the 27th of December 2019 placing Shijian-20 into supersynchronous orbit flawlessly clearing paths for future projects.
