BBC reports the picture shows parts of the static lander and the robotic rover, which is now exploring the landing site at Von Kármán crater on the Moon's far side. The Chang'e-4 mission was the first such attempt to touch down on the side of the Moon that we don't see. Chang'e-4 was launched from Xichang Satellite Launch Centre in China on 7 December. It touched down at 10:26 Beijing time (02:26 GMT) on 3 January. This is the first mission to explore the Moon's far side from the surface.

Because of a phenomenon called "tidal locking", we see only one face of the Moon from Earth. This is because the Moon takes just as long to rotate on its own axis as it takes to complete one orbit of Earth.

The far side is more rugged, with a thicker, older crust that is pocked with more craters. There are also very few of the "maria" - dark basaltic "seas" created by lava flows - that are evident on the more familiar near side.

The rover and lander are carrying instruments to analyse the unexplored region's geology.
