China’s Yutu 2 rover just turned two years old, and NASA’s Lunar Reconnaissance Orbiter has kept a sharp eye on its movements during its mission on the far side of the moon.

While China’s Chang’e 5 sample-return mission has been basking in the lunar limelight, the Chang’e 4 mission was also back in action. Chang’e 4 launched to the moon in May 2018 and deployed the Yutu 2 rover to the lunar surface on Jan. 3, 2019. The sun rose over Von Kármán crater on Dec. 7, meaning the solar-powered lander and Yutu 2 rover were active on Dec. 9.
