BEIJING (CNSA PR) — At 23:11 on December 1, the Chang’e-5 probe successfully landed on the pre-selected landing area on the nearside of the moon at 51.8 degrees west longitude and 43.1 degrees north latitude, and returned the landing image.

At 22:57 on December 1, the combination of Chang’e-5 lander and ascender began to perform a power drop from about 15 kilometers away from the moon surface. The 7,500 N variable thrust engine was turned on, and the relative speed of the probe relative to the moon was gradually increased from about 1.7 km/sec. 

During this period, the probe made rapid attitude adjustments and gradually approached the moon surface. After that, automatic obstacle detection was carried out. After the landing site was selected, the obstacle avoidance and slow vertical descent began, and the land steadily landed in the area north of the Rumker Mountain in the Ocean of Storms. During the landing, the landing camera equipped with the lander took an image of the landing area.

After the successful landing, the lander under ground control has carried out inspection and setup work, such as the deployment of the solar wing and the directional antenna, and will officially start the lunar surface work lasting about 2 days to collect lunar samples.
