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 rover 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:

3827 December 2021 – 10 January 2022 The Yutu-2 rover made another fast sprint to reach the “Lunar hut”. But as expected it is not a artificial moon hut. It is just a rock. The scientists renamed the rock to “Jade rabbit” because it is shaped like a small gracing rabbit.38.10 m1,003.90
399 FebruaryThe Chang’e-4 moon rover inspected a smaller & younger crater on the edge of another 26 m large crater before Chinese New Year. The “Jade rabbit” was also in focus of the science investigations on this moon day. Next to the rabbit shaped rock formation the rover found 2-3 cm large translucent glass spheres. It already discovered smaller glass spheres before.61.60 m1,065.50 m
4025 February – March 10 2022Yutu-2 spotted a interesting stone formation – called “Dragon Ridge” (龙脊). The scientists decided to drive the next days to this rock to investigate this tiny ridge. The tiny moon rover sent also a photo back which shows the Chang’e-4 lander in the far distance.46.64 m1,112.14 m
41March 26 – 8 April 2022The moon rover Yutu-2 arrived the “Dragon Ridge” and investigate the rock. After the investigation the rover continued its journey to the northwest.30.24 m1,142.38 m
4227 April – 12 May 2022It is expected that the moon rover is heading more to the northwest.??
