China is going back to the Moon for more samples.

On Friday the country launched its largest rocket, the Long March 5, carrying an orbiter, lander, ascent vehicle, and a return spacecraft. The combined mass of the Chang'e-6 spacecraft is about 8 metric tons, and it will attempt to return rocks and soil from the far side of the Moon—something scientists have never been able to study before in-depth.

The mission's goal is to bring about 2 kg (4.4 pounds) of rocks back to Earth a little more than a month from now.
