STORY: The Long March-5, China's largest rocket, blasted off at 5:27 p.m. Beijing time (0927 GMT) from Wenchang Space Launch Center on the southern island of Hainan with the more than 8 metric ton Chang'e-6 probe.

Chang'e-6 is tasked with landing in the South Pole-Aitken Basin on the far side of the moon, which perpetually faces away from the Earth, after which it will retrieve and return samples.

The launch marks another milestone in China's lunar and space exploration programme.
