Chang’e-4 – Landing on the far side of Moon

China’s Chang’e-4 mission is the first mission where China achieved a major first in spaceflight. They landed with a lander on the far side of Moon.

The Chang’e-4 were launched on 7th December 2018 on a Long March 3B rocket at the Xichang Satellite Launch Center and entered lunar orbit on 12th December 2018. After calibrating the orbit and checking all systems the lander with a weight of 1,060 kg achieved a soft landing on 3rd January 2019 inside of the Karman crater of the South Pole-Aitken Basin on the far side of the Moon.

The Chang’e-4 was the backup for the successful Chang’e-3 mission, so also this moon lander had a rover onboard. The 1rover with a weight of 140kg and a size of 1x1x1.5 meters – called Yutu-2 rolled down to the moon surface shortly after the landing and performed already for the first day a 50 meter drive. The first drive was a 160 degree drive around the lander. Lander and rover made pictures of each other. Since January 2019 the Yutu-2 rover is driving and exploring the lunar surface successful. The Yutu-2 rover is the record holder for the longest lifetime of a Moon rover since December 2019. Before the record holder was the Soviet rover Lunokhod-1 who survived 322 days on the Moon surface.

The Table shows the driving activities of the Chang’e-4 rover Yutu-2 since landing in January 2019 till End of February 2021:
