The returner of the Chang’e-6 probe touched down on Earth on Tuesday, bringing back the world’s first samples collected from the moon’s far side.

The return capsule landed precisely in the designated area in Siziwang Banner, north China’s Inner Mongolia Autonomous Region, and the mission is a complete success, according to the China National Space Administration (CNSA).

Chang’e-6 is one of the most complex and challenging missions in China’s space exploration efforts to date.

Consisting of an orbiter, a returner, a lander and an ascender, it was launched on May 3 this year, and has gone through various stages such as Earth-moon transfer, near-moon braking, lunar orbiting and separation of the lander-ascender combination and the orbiter-returner combination.

Supported by the Queqiao-2 relay satellite, the lander-ascender combination landed at the designated landing area in the South Pole-Aitken (SPA) Basin on the far side of the moon on June 2 and carried out sampling work.

On June 4, the ascender took off from the moon with samples and entered the lunar orbit. On June 6, it completed rendezvous and docking with the orbiter-returner combination and transferred samples to the returner.

The ascender then separated from the combination and landed on the moon under ground control to avoid becoming space junk.

The orbiter-returner combination spent 13 days in lunar orbit, awaiting the right opportunity to return to Earth.

After completing two moon-Earth transfer maneuvers and one orbital correction, the returner separated from the orbiter and delivered the samples to Earth.
