According to the report, "of unmanned spacecraft was launched from China in early December 2018 Chang'e 4 yes (Chang'e 4)" it is, from the Earth landed in the crater of the moon to be back. The "backside of the moon" which the No. 4 landed is "a place that can not be directly observed from the earth", and it is a place with many unknown parts such as the underground structure.嫦娥 4 has landed in the vicinity of the Antarctic on the back of the moon and this landing will be an important technical achievement for China, the international media The Verge reports.

China was the third to succeed in soft landing to the moon, China was the first in the world to land on the back of the moon. There are no examples of successful landings so far because the backside of the moon is a difficult point to communicate with, not to mention observations. In order to land on the back side of the Moon, No. 4 has placed a bridge of relay satellite at the Lagrangian point , and this spacecraft was launched on May 20, 2018.

嫦娥 No.4 has landed on the back side of the moon is reported on the official Twitter by China Xinhua Inc., a state-run telecommunications company in China around 14 o'clock on January 3, 2019.

嫦娥 No. 4 has landed in the vicinity of Antarctica on the back of the moon, so it seems possible to photograph the wonderful landscape of the Antarctic Aitken Basin . This Antarctic Aitken basin is located behind the moon and therefore it was a place where scientists could not observe in detail. It is a crater of about 2,500 kilometers in diameter and about 13 kilometers in depth, considered to be the largest crater in the solar system, the largest in the month. Scientists speculate that the Antarctic Aitken Basin is a crater made when huge rocks hit the moon billions of years ago. It is thought that 嫦娥 4 can land on the back side of the moon, it will be possible to estimate more accurately when this crater was formed, so what kind of environment of the solar system at that time It is expected that there will be many clues to know if there was.

嫦娥 4 is expected to develop a rover soon to investigate the Antarctic Aitken basin.
