China’s Chang’e-4 lands on moon’s far side


The Chinese Chang’e-4 moon lander touched down in the Von Karman crater moon’s farside. No, the far side of the moon does not always stay dark. In fact, Chang’e-4 mission controllers waited for sunrise over this region to set the lander down. Simulation of lunar farside today, via Alan Dyer (@amazingskyguy on Twitter).

More space history this week, besides the smallest space object ever orbited, and the most distant object yet visited. Last night, according to clocks in the Americas – January 3, 2019 at 02:26 UTC (10:26 a.m. Beijing time; January 2 at 10:26 p.m. on the U.S. east coast) – China’s Chang’e-4 spacecraft successfully landed on the moon’s far side.

Chinese state media announced the event. The spacecraft landed in Von Kármán crater, located on the lunar farside within the South Pole-Aitken basin. Jason Davis at the Planetary Society wrote:

Chang’e-4 itself launched on December 8, 2018. It entered lunar orbit four days later, where mission controllers spent 22 days testing the spacecraft’s systems, waiting for the sun to rise at the landing site. [On January 2-3, 2019] Chang’e-4 successfully de-orbited and landed.

Scientists say Chang’e-4’s landing site is an area where an ancient impact by space debris pounded the moon long ago, possibly exposing some of the lunar mantle, the layer beneath its crust. So it’s an interesting region geologically. Chinese scientists hope to learn more about the early history of our moon (and by extension the Earth and rest of the solar system) by studying this region via Chang’e-4.

The spacecraft is a combination lander-rover. At this writing, there’s no word that the rover has been deployed, but that’s expected soon. Stay tuned!

Bottom line: China’s Chang’e-4 spacecraft set down on the moon’s far side on January 3, 2019 at 02:26 UTC. It’s the first time a spacecraft has landed on the far side of the moon.
