TapTechNews June 3rd, the @Chang'e-6 Lunar Probe tweeted its first tweet this evening: Hello everyone, I'm Chang'e-6 and I'm currently scooping soil on the moon. Notably, this tweet shows From the Moon.

Change-6's First Tweet and Landing on the Moon_0

At 6:23 am on June 2nd, the lander and ascender combination of Chang'e-6 successfully landed in the pre-selected landing area in the South Pole-Aitken Basin on the far side of the moon with the support of the Queqiao-2 relay satellite.

Learned from the official website of the National Space Administration, at 6:09 am on June 2nd, the lander and ascender combination of Chang'e-6 began to implement powered descent, and the 7500-newton variable-thrust main engine started. During this period, the combination carried out rapid attitude adjustment and gradually approached the lunar surface. Then, through the visual autonomous obstacle avoidance system for automatic obstacle detection, using the visible light camera to select the roughly safe point according to the brightness of the moon surface, hovering 100 meters above the safe point, and using laser three-dimensional scanning for accurate photography to detect lunar surface obstacles, and finally selected the landing point, and began to slowly and vertically descend. When it was about to reach the moon surface, the engine was shut off, and the buffer system was used to ensure that the combination reached the moon surface in a free-fall manner, and finally landed smoothly on the far side of the moon in the South Pole-Aitken Basin.

The Chang'e-6 mission implements the first human lunar far-side sampling return. The project has many innovations, high risks, and great difficulties. Compared to the Chang'e-5 mission that achieved lunar near-side sampling return in 2020, the Chang'e-6 mission has broken through the design and control technology of the lunar retrograde orbit and will complete key technical nodes such as intelligent and rapid sampling on the far side of the moon and taking off and ascending on the far side of the moon with the support of the Queqiao-2 relay satellite.
