China just took a huge leap forward in its plans to dominate space.

On Tuesday, its Chang'e-6 lunar probe successfully returned to Earth carrying the first-ever samples from the moon's far side. 

A video showed an official triumphantly planting a Chinese flag near the capsule in Mongolia after it glided back to our planet by parachute.

The samples, which include 2.5 million-year-old volcanic rock, could answer crucial questions about how planets form, as well as the moon's history.
