Introduction

China’s pursuit of space mining begins with its lunar exploration program, notably the successful Chang’e missions. These endeavors, involving lunar landings, sample collections, and surface mapping, form the groundwork for understanding lunar composition and potential resource extraction. Beyond exploration, China envisions a permanent lunar research base as a strategic hub for scientific endeavors, resource extraction, and potential human habitation.

China’s Lunar Ambitions: A Stepping Stone to Space Mining

China’s lunar exploration program is laying the foundation for its future endeavors in space mining. The nation’s Chang’e lunar exploration missions have successfully landed on the Moon, collected samples, and mapped its surface. These missions have provided invaluable insights into the Moon’s composition and resource potential, paving the way for future resource extraction.

Chang’e 3 (2013): Achieved the first lunar landing since the 1970s with its Yutu rover.
Chang’e 4 (2018): Conducted the first-ever landing on the Moon’s farside.
Chang’e 5 (2020): Successfully returned lunar samples to Earth, a feat not accomplished since 1976, providing new insights into the Moon’s history and geology.

Future plans include: China’s lunar ambitions extend beyond exploration. The nation has plans to establish a permanent lunar research base, providing a foothold for future space mining operations.

Chang’e 6: Aiming to return samples from the lunar South Pole-Aitken basin.
International Lunar Research Station: A long-term project to establish a robotic and eventually human-inhabited base on the Moon, seeking international collaboration.

This base could serve as a hub for scientific research, resource extraction, and potential human habitation. The nation also plans to develop technologies to extract resources such as helium-3, a rare isotope that could be used for nuclear fusion.

Mars Exploration

China has also marked its presence on Mars. In May 2021, China became the second country after NASA to land a rover on Mars with the Tianwen 1 mission. The Zhurong rover completed 347 martian days of exploration, far exceeding its expected lifespan. One of its significant discoveries was evidence suggesting the recent presence of water at its landing site.

Tianwen 1 (2020): Successfully placed an orbiter around Mars and deployed the Zhurong rover, which operated beyond its expected lifespan, studying the planet’s geology and searching for signs of water.
Mars Sample-Return Mission: Scheduled for around 2030, the Tianwen 3 mission aims to collect and return samples from Mars. This complex mission will build on the technological successes of previous lunar and martian missions. Collecting samples from Mars will be more challenging than from the Moon. The much greater distance and time delay require greater automation, and adjustments will need to be made for Mars’ gravity. Launching a two-stage rocket from inside the martian atmosphere is a different proposition than a single-stage launch from the airless Moon.

James Head III, a planetary scientist at Brown University, notes that these missions are fostering a vibrant scientific community in China, excited about the new opportunities and data.

Broader Solar System Exploration

China is also planning significant missions beyond the Moon and Mars:

Queqiao 2 and Chang’e 6: In 2024, the Queqiao 2 lunar relay satellite will support the Chang’e 6 mission to the Moon’s farside, aiming to collect samples from the South Pole-Aitken basin.
Tianwen 4 (2030): A mission to explore Jupiter’s moons and perform a flyby of Uranus. China’s first voyage to the outer planets is scheduled for 2030 with Tianwen 4, which will set out for Jupiter. After a period where it will roam the jovian system, conducting flybys of Jupiter and its moons, the mission will settle in around Callisto, the outermost of the four Galilean moons. It lies outside Jupiter’s fierce radiation belts and also has — unlike Ganymede, Io, and Europa — an ancient surface, which could harbor clues to the history of the jovian system. Honing in on Callisto will also complement ESA’s JUICE mission, which focuses on Ganymede, and NASA’s Europa Clipper. But Tianwen 4 will have another major component: An additional probe will continue on for Uranus, performing a rare flyby of the ice giant in the 2040s.
Interstellar Exploration: Planning twin probes to study the heliosphere’s boundaries, potentially visiting minor planets along the way. They are separately destined for the head and tail of the heliosphere — the bubble of the Sun’s magnetic influence, which is deflected back as it moves through the interstellar medium.The two craft will not be the first to explore the heliosphere — both Voyager missions have reached its boundary and crossed over into interstellar space. But the Voyagers were planetary missions, first and foremost, focused on the flybys enabled by a rare alignment of planets; only later were they adapted for improvised heliosphere measurements. China’s probes will be optimized for heliosphere research, while also taking advantage of planetary flybys.

These missions involve complex maneuvers and innovative techniques, such as the touch-and-go sampling method and the anchor-and-attach process, demonstrating China’s growing prowess in space technology.

Asteroid Mining: The Next Frontier

China’s vision extends beyond the Moon to asteroids, celestial bodies holding vast reservoirs of precious metals, minerals, and water. Asteroid mining presents a frontier solution to Earth’s resource demands. China has already demonstrated its commitment with the Chang’e-2 probe’s successful encounter with the asteroid Toutatis, providing crucial data on the composition and potential mining methodologies.

Tianwen 2: Set to launch in 2025, this mission will collect samples from the near-Earth asteroid 469219 Kamo‘oalewa and later rendezvous with the main-belt comet 311P/PanSTARRS.

China’s commitment to space exploration is further evidenced by its upcoming missions, such as the launch of the robotic probe Tianwen-2 in 2025 to collect samples from the near-Earth asteroid 2016 HO3. Additionally, the Chang’e-7 spacecraft is anticipated to land at the moon’s south pole in 2026, exploring the potential for water ice that could be utilized for various purposes, including sustaining astronauts during prolonged lunar missions.

Interplanetary Roadmap

In a bold stride towards the forefront of space exploration, China has unveiled a visionary roadmap outlining plans for a comprehensive space resources system spanning the entire solar system by 2100. Notably, the plan highlights the economic viability of mining approximately 122 asteroids near Earth, estimated to be worth over US$100 trillion each, considering technical feasibility and cost-effectiveness.

Spearheaded by Wang Wei, lead scientist at the China Aerospace Science and Technology Corporation, the initiative aims to economically explore, mine, and leverage water ice and mineral resources not only on the moon but also in deep space, marking a pivotal shift in the economic dynamics between nations.
