China has achieved a significant milestone in space exploration. The Chang'e 6 mission successfully landed on the far side of the moon on June 2, 2024. This historic mission is part of China's lunar exploration program and marks the second time China has landed a spacecraft on the moon's far side. The mission aims to collect rock and soil samples from the dark lunar hemisphere, which could provide valuable insights into the geological differences between the moon's far side and the more familiar near side.
The Chang'e 6 probe touched down inside the Apollo Crater, within the giant South Pole-Aitken basin. The mission is notable for being the first to attempt to return samples from the moon's far side to Earth. The successful landing elevates China's status as a major player in the global space race and brings it a step closer to its goal of sending humans to the moon.
This mission involves many engineering innovations and presents high risks and great difficulty due to the challenges of landing and communicating from the moon's far side. The far side of the moon always faces away from Earth, requiring special relay orbiters to maintain communication, which China had launched ahead of both Chang'e 4 and Chang'e 6 missions.
The Chang'e-6 mission, China's historic endeavor to collect samples from the far side of the moon, has several important scientific goals:
The mission aims to conduct on-site investigation and analysis of the landing area on the far side of the moon. By examining the geological setting and detailed context of the sampling site, scientists hope to gain insights into the unique features and composition of this previously unexplored lunar region.
Chang'e-6 will collect unique lunar samples from the far side. These samples include both surface regolith and subsurface material. The spacecraft will use a scoop to grab soil and rocks, as well as a drill to retrieve deeper samples. These samples are expected to provide crucial data about the moon's geological mysteries and its early history.
The far side of the moon differs significantly from its near side. Most ancient volcanic activity occurred on the near side, while the far side remained quieter under a thick, heavily cratered crust. By analyzing samples from the far side, scientists hope to unravel the reasons for this asymmetry and gain a deeper understanding of lunar geology and evolution.
Comprehensive laboratory analysis and characterization of the returned samples will help establish a relationship between in situ measurements (taken directly on the moon) and laboratory data. This ground truth information will enhance our understanding of lunar processes and the formation of the moon.
Overall, Chang'e-6's successful mission could provide a treasure trove of scientific insights and contribute to humanity's knowledge of our celestial neighbor.
