China landed a spacecraft on the Moon this weekend for the fourth time, successfully placing its Chang’e 6 lander in the South Pole-Aitken Basin on the far side of the Moon.

After the landing on Saturday evening (United States time), the autonomous spacecraft will spend about 48 hours collecting samples. It will do so by two different means, drilling to collect material from beneath the ground, as well as using a robotic arm to gather regolith from the surface.
