Since landing on the back of the moon, the Chang’e 4 lander and the Yutu-2 lunar rover have been operating successfully for more than 500 days, and have achieved many results in the scientific fields such as the material composition and underground structure of the landing zone.
During the eighth day of the month, the Yutu 2 lunar rover found an unknown substance with a size of about 52 cm x 16 cm inside a fresh impact crater with a diameter of about 2 m and a depth of about 0.3m. Compared with the surrounding lunar soil, the unknown substance has an irregular shape, showing a black-green color with a certain luster.
In response, the flight control team of the Beijing Aerospace Flight Control Center has formulated a strict driving plan and conducted detailed scientific detection of fresh impact craters and unknown substances.
