Unearthing the moon's secrets, little by little
China DailyRecovery personnel check the reentry capsule of the Chang'e 6 probe on Tuesday after it landed in Siziwang Banner in North China's Inner Mongolia autonomous region. The Chang'e 6 mission has brought back to Earth the first samples ever collected from the far side of the moon. WANG FEI/FOR CHINA DAILY The Chang'e 6 mission is unique in being mankind's first mission to bring back samples from the far side of the moon. While the area where Chang'e 5 landed, namely Mons Rümker, was formed 2 billion years ago, the samples collected by Chang'e 6 come from the South Pole-Aitken basin that's the largest, deepest, as well as the oldest crater basin not only on the moon but in the entire solar system. According to existing knowledge, collisions might have led to the creation of this crater on the moon's surface, which means the lunar soil collected by Chang'e 6 could be 4 billion years old and reveal secrets of the solar system during that early period.
