A Long March-5 rocket, carrying the Chang'e-6 spacecraft, blasted off from its launchpad at the Wenchang Space Launch Site in Hainan on Friday afternoon.

The Chang'e-6 mission is tasked with collecting and returning samples from the moon's mysterious far side, the first endeavor of its kind in the history of human lunar exploration.

"Collecting and returning samples from the far side of the moon is an unprecedented feat. Now we know very little about the moon's far side. If the Chang'e-6 mission can achieve its goal, it will provide scientists with the first direct evidence to understand the environment and material composition of the far side of the moon, which is of great significance," said Wu Weiren, an academician of the Chinese Academy of Engineering and chief designer of China's lunar exploration program.

The Chang'e-6 spacecraft, like its predecessor Chang'e-5, comprises an orbiter, a lander, an ascender and a returner.

After it reaches the moon, it will make a soft landing on the far side. Within 48 hours after landing, a robotic arm will be extended to scoop rocks and soil from the lunar surface, and a drill will bore into the ground. Scientific detection work will be carried out simultaneously.

After the samples are sealed in a container, the ascender will take off from the moon and dock with the orbiter in lunar orbit.

The returner will then carry the samples back to Earth, landing in north China's Inner Mongolia Autonomous Region. The entire flight is expected to last about 53 days, the China National Space Administration said. (Xinhua)
