As of 10 November 2020, The CNSA –China National Space Administration Belt and Road Initiative Lunar Mission CLEP on the One Hundred Kilometer diameter Von Karman Crater Chang’e 4 lander and the “Yutu 2” lunar rover the Chang’e-4 lander and the “Yutu-2” lunar rover have completed 21-month scientific exploration on the back of the moon. They broke through 677 Earth Days On the far back of the moon, the Chang’e 4 lander and the “Yutu 2” lunar rover ended their moon night dormancy at 3:12 on November 10 and 10:17 on November 9 respectively. They were awakened by light and ushered in the first 24 days. Up to now, Chang’e-4 has successfully operated for 677 Earth days.
Based on the data of the panoramic camera spliced images and DOM images of the detection point, the “Yutu-2” lunar rover will continue to drive northwest during the 24th day of the month, targeting the basalt direction or the impact crater area with high reflectivity. Near the noon of the moon, the “Yutu-2” lunar rover plans to take at least one panoramic camera ring shot, and the infrared imaging spectrometer, neutral atom detector, and lunar radar will carry out simultaneous detection.

As the “Yutu-2” lunar rover continues to move northwest, scientists from the core team of Chang’e-4 use the first-hand data returned to continue to produce scientific results. The scientific team recently published an article in the SCI journal “Science China Information Sciences” and pointed out that the impact during the formation of the Antarctic-Aitken Basin is likely to penetrate the lunar crust and impact deep lunar material.
Since the remote sensing observation of the back of the moon by orbiting satellites, a large number of studies have revealed the existence of mafic anomalies at the bottom of the Antarctic-Aitken Basin, which also have different chemical properties compared to returned samples and lunar meteorites. Chang’e-4 probed the sputter layer at the bottom of the impact crater in the Antarctic-Aitken Basin and found that the characteristics of mafic minerals in this area are similar to remote sensing data.
Research data shows that the mafic minerals in the rocks and lunar soil in the Chang’e 4 landing area are dominated by clinopyroxene, which has the same composition as the rapidly cooling magma system. It is believed that the material in the landing zone of Chang’e 4 mainly comes from the recrystallization of the impact melt. The patrol and detection of “Yutu-2” in this area provided a scientific basis for in-depth understanding of the cause of the mafic anomaly at the bottom of the Antarctic-Aitken Basin….
随着“玉兔二号”月球车向西北方向不断前行，嫦娥四号核心团队科学家利用传回的第一手数据，持续产出科学成果。科学团队近期发表在SCI期刊《Science China Information Sciences》上的一篇文章中指出：南极–艾特肯盆地形成时的撞击很可能穿透月壳，撞击出月球深部物质。
