 "Chinese capsule with first moon rocks in 4 decades begins return to Earth")
A Chinese space capsule bringing back the first moon rocks in more than four decades has begun its return to Earth.
The Chang'e 5 lunar probe left the moon's orbit on Sunday morning by activating four engines for about 22 minutes, the China National Space Administration said in a social media post.
The mission landed on the moon earlier this month and collected about 2 kilograms (4.4 pounds) of samples.
The return capsule is expected to land in northern China in the Inner Mongolia region after a three-day journey.
The material would be the first brought back since the Soviet Union's Luna 24 probe in 1976.
