In a groundbreaking leap for space exploration, China has successfully launched a world-first mission to retrieve samples from the far side of the moon. The launch, which took place on May 3, 2024, marks a significant milestone in lunar exploration and is set to bring back invaluable insights into the history and composition of our celestial neighbor.
The Chang'e-6 mission, named after the Chinese Moon goddess Chang'e, is the successor to the Chang'e-5 mission, which successfully returned lunar samples from the near side of the moon in December 2020. This time, the focus is on the far side of the moon, a region that has never been explored by humans or robotic missions from Earth.
The far side of the moon, also known as the "dark side" despite receiving sunlight just like the near side, is of particular interest to scientists due to its unique geological features and the possibility of discovering new types of lunar material. The mission aims to collect up to 4.4 pounds (2 kilograms) of lunar dirt and rock, some of it scraped from the surface and some of it drilled from up to 6.5 feet (2 meters) underground.
The mission architecture is similar to that of the Chang'e-5 mission, with a lander and ascender touching down inside the Apollo crater, part of the South Pole-Aitken basin. This basin is one of the largest impact craters in the solar system and is thought to hold clues about the moon's early history and the formation of the Earth-Moon system.
After collecting the samples, the lander will transfer them to an ascent vehicle, which will blast off from the lunar surface and enter into lunar orbit. A return capsule will then carry the samples back to Earth, where scientists eagerly await their arrival.
The Chang'e-6 mission not only represents a significant achievement in space exploration but also underscores China's growing capabilities and ambitions in space. As we look forward to the insights that the mission will bring, it is clear that this is just the beginning of a new chapter in lunar exploration.
