China’s champion – long duration Yutu-2 rover.

During the eighth lunar day of exploration, the Yutu-2 rover found colloidal substance in a pit on the Moon’s surface, and after further research, experts believe that it might be breccia formed by impact.

Smashing, melting and mixing

Lunar breccias are rocks produced by the smashing, melting, and mixing of the lunar surface materials by large and small meteoric impacts. Most of the breccias returned by the Apollo missions were formed in the ancient lunar highlands about 3,900 to 4,000 million years ago.

Up to now, Yutu-2 rover has worked on the Moon’s farside for 18 lunar days.

China’s Chang’e-4 probe and Yutu-2 rover resumed work on June 15, and entered their 19th lunar day of exploration.
