Farside...

So, the Chinese beat the west to the far side of the moon. Maybe I should care more about that - but I care that we finally landed something on the far side.

The rover successfully touched down at 10:26am Beijing time in the South Pole-Aitken Basin.

The large technical challenge of the far side is this: It's in radio shadow from Earth. Because of this, the Chinese had to launch a specialist satellite to act as a comms relay. (Because of that radio shadow, I have personally predicted that we will eventually build a radio observatory on the far side of the moon, where it is protected from false signals from Earth).

Here's the first image the probe sent back:


It looks smoother than the near side, doesn't it. But it is in the bottom of an impact crater...

Keep doing science, Chang'e 4.
