Chang'e-5 mission is the first lunar sample-return mission since the 1970s.
China is the third country to have retrieved lunar samples after the United States and the Soviet Union.

□ ABOUT CHANG'E 5 PROBE

◇ The rocket is comprised of four parts: an orbiter, a returner, an ascender and a lander.

◇ The objective of the mission is to bring back lunar rocks, the first attempt by any nation to retrieve samples from the moon in four decades.

□ Identified location for the collection of samples:

The Chinese probe collected surface material from a previously unexplored area known as Oceanus Procellarum — or “Ocean of Storms” — which consist of a vast lava plain.
