Chinese Lunar Exploration Program

The Chinese Lunar Exploration Program (CLEP; Chinese: 中国探月; pinyin: Zhōngguó Tànyuè), also known as the Chang'e Project (Chinese: 嫦娥工程; pinyin: Cháng'é Gōngchéng) after the Chinese Moon goddess Chang'e, is an ongoing series of robotic Moon missions by the China National Space Administration (CNSA). The program encompasses lunar orbiters, landers, rovers and sample return spacecraft, launched using the Long March series of rockets. A human lunar landing component may have been added to the program, after China publicly announced crewed lunar landing plans by the year 2030 during a conference in July 2023.

The program's launches and flights are monitored by a telemetry, tracking, and command (TT&C) system, which uses 50-meter (160-foot) radio antennas in Beijing and 40-meter (130-foot) antennas in Kunming, Shanghai, and Ürümqi to form a 3,000-kilometer (1,900-mile) VLBI antenna. A proprietary ground application system is responsible for downlink data reception.

Ouyang Ziyuan, a geologist, chemical cosmologist, and the program's chief scientist, was among the first to advocate the exploitation not only of known lunar reserves of metals such as titanium, but also of helium-3, an ideal fuel for future nuclear fusion power plants. Ye Peijian serves as the program's chief commander and chief designer. Scientist Sun Jiadong is the program's general designer and Sun Zezhou is deputy general designer. The leading program manager is Luan Enjie.

The first spacecraft of the program, the Chang'e 1 lunar orbiter, was launched from Xichang Satellite Launch Center on 24 October 2007, having been delayed from the initial planned date of 17–19 April 2007. A second orbiter, Chang'e 2, was launched on 1 October 2010. Chang'e 3, which includes a lander and rover, was launched on 1 December 2013 and successfully soft-landed on the Moon on 14 December 2013. Chang'e 4, which includes a lander and rover, was launched on 7 December 2018 and landed on 3 January 2019 in the South Pole-Aitken Basin, on the far side of the Moon. A sample return mission, Chang'e 5, which launched on 23 November 2020 and returned on 16 December in the same year, brought 1,731 g (61.1 oz) of lunar samples back to Earth.

As indicated by the official insignia, the shape of a calligraphic nascent lunar crescent with two human footprints at its center reminiscent of the Chinese character 月, the Chinese character for "Moon", the ultimate objective of the program is to pave the way for a crewed mission to the Moon. China National Space Administration head Zhang Kejian had announced that China is planning to build a scientific research station on the Moon's south pole "within the next 10 years," (2019–2029).

On 12 July 2023, at the 9th China (International) Commercial Aerospace Forum in Wuhan, Hubei province, Zhang Hailian, a deputy chief designer with the China Manned Space Agency (CMSA), publicly introduced a preliminary plan to land two astronauts on the Moon by the year 2030.
