A Shandong University team from east China studied a geological anomaly within the Moon’s deepest, largest and oldest crater, South Pole-Aitken Basin. This is located on the far side Earth’s natural satellite.
Chinese scientists discovered that the mantle beneath the crater is rich in plagioclases, a group of rock-forming mineral of the isomorphic sequence. These minerals are typically found in the lunar crust’s surface layer. Experts don’t rule out the possibility that there was an important collision between the Moon and the basin after its formation.
The Chang’e-4 station launched December 8, 2018, and retrieved the data. After 44 lunar days of work on the Moon (each lasting approximately 14.5 Earth day), she is now in sleep mode as the next dark period of the day has arrived (night on Earth’s natural satellite lasts for two weeks).
The largest known moon crater is the South Pole-Aitken Basin. It is located on the south side. It measures 2400 x 2050km, making it one of the largest craters within the solar system. It is the oldest and deepest known impact structure on Moon. The basin’s depth is 8 km and its total height interval 16.1 km.
