Chang'e-6: China's Ambitious Mission to the Moon
China launches Chang'e-6 mission to collect lunar samples from the far side of the Moon. Complex maneuvers and automated docking required for sample transfer. Samples from the South Pole-Aitken Basin hold valuable insights into the Moon's origins.
This mission, set to bring back lunar samples, is just the beginning of China's grand plans for the Solar System.
On May 3rd, China launched four spacecraft towards the Moon, marking one of its most ambitious missions to date. The primary objective is to collect samples from the lunar far side and safely return them to Earth. This endeavor holds the potential to provide valuable insights into the early history of the Solar System and our own planet.
The Chang'e-6 spacecraft embarked on a 4.5-day journey to the Moon. Once in lunar orbit, a lander will separate from the orbiter and target a landing area within the Apollo crater on the far side of the Moon. This area, which never faces Earth, will rely on the Queqiao-2 communications relay satellite for operations and communication with Earth.
Equipped with a scoop and drill, the lander will collect surface and subsurface materials. These samples will then be blasted into lunar orbit by an ascender, which will rendezvous with the orbiter to transfer the precious cargo.
The complexity of this mission lies in the precise rendezvous and docking between the orbiter and ascender, all while traveling at a speed of over a mile per second. Due to the distance from ground stations on Earth, these maneuvers will need to be automated.
Once the samples are transferred to a reentry capsule, it will be released just before the orbiter reaches Earth. The capsule will undergo a controlled descent through Earth's atmosphere, landing in the grasslands of Inner Mongolia.
The samples, taken from the South Pole-Aitken Basin, a vast impact crater, hold immense scientific value. They will help answer questions about the Moon's origins, geological evolution, and the differences between the near and far sides of the Moon.
Beyond the scientific significance, the Chang'e-6 mission also reflects China's broader ambitions in space exploration. These maneuvers serve as practice for potential future missions, including the retrieval of samples from Mars. While NASA and the European Space Agency face delays and challenges in their Mars sample return project, China could potentially achieve a significant space "first."
Moreover, the complexity of the Chang'e-6 mission hints at China's aspirations for crewed lunar missions. China plans to launch its first crewed lunar mission before 2030, with astronauts spending time on the lunar surface before returning to orbit, similar to NASA's Apollo missions.
China's long-term vision extends beyond short-term lunar presence. They aim to establish a lunar base, with planned missions to the Moon's south pole, testing the use of lunar soil for 3D printing bricks.
These efforts align with China's Moon base initiative and its parallel development of cornerstone technologies, such as nuclear reactors for power during lunar nights. This initiative, along with Russia, aims to attract countries for a joint International Lunar Research Station.
