China’s lunar probe has returned to Earth with the first ever samples from the Moon’s unexplored far side.
The Chang’e-6 landed in the Inner Mongolia desert on Tuesday, after a nearly two-month long mission which was fraught with risks.
Scientists are eagerly awaiting the Chang’e-6 as the samples could answer key questions about how planets are formed.
China is the only country to have landed on the far side of the Moon, having done so before in 2019.
The far side – which faces away from Earth – is technically challenging to reach due to its distance, and its difficult terrain of giant craters and few flat surfaces.
Scientists are interested in this less-explored side as it is hoped it may contain traces of ice, which can be harvested for water, oxygen, and hydrogen.
The Chang’e-6 mission is a source of pride for a nation which has stepped up its missions to the Moon – drawing attention from its rival, the US.
State media showed officials planting the Chinese flag with a flourish just after the Chang’e-6 capsule landed in the desert of Inner Mongolia.
China’s President Xi Jinping has called to congratulate those at the command centre of the Chang’e-6 mission.
Mr Xi said he hopes they can carry on exploring deep space and “reaching new heights in unravelling the mysteries of the universe… to benefit humanity and advance the nation”.
The Chang’e-6 blasted off from a space centre in early May, and successfully landed on a crater close to the Moon’s south pole a few weeks later. Its mission lasted 53 days.
The probe will be sent to Beijing and samples will be retrieved there, according to state broadcaster CCTV.
This is China’s sixth mission to the Moon, and its second to the far side. The probe is named after the moon goddess Chang’e in Chinese mythology.
The probe used a drill and a robotic arm to scoop up soil and rocks, took some photos of the surface and planted a Chinese flag.
Catherine Heymans, the astronomer royal for Scotland, hoped the samples would help test theories about how the Moon was formed 4.5 billion years ago and whether it resulted from a collision with a very early version of the Earth.
“it’s incredibly exciting to see this landing successfully,” she told the BBC. “The geological activity on the Moon is very different on the near side and the far side and it’s been a big puzzle why we see those differences.”
She hoped the samples brought back would help researchers understand the composition of the centre of the Moon.
“Is it very similar to the Earth? Can that confirm our theory that the Earth and the Moon were once the same thing?”
Beijing has poured huge resources into its space programme over the past decade in an effort to catch up with both the US and Russia.
It aims to send a crewed mission to the Moon by 2030 and plans to eventually build a base on the lunar south pole.
The US also plans to put astronauts back on the Moon by 2026 with its Artemis 3 mission.
Analysts believe the next space race will not just be about putting people on the Moon – it will be about who is able to stake their claim and control lunar resources.
