According to state media, a Chinese lunar probe module successfully launched on Tuesday from the Moon’s far side, bringing samples that will be returned to Earth.
The accomplishment represents a first for the world and the most recent development in Beijing’s long-running space program, which intends to launch a crewed mission to the Moon by 2030.
The China National Space Administration (CNSA) was cited by state news agency Xinhua as saying that the ascender module of the Chang’e-6 probe “lifted off from lunar surface”.
It described it as “an unprecedented feat in human lunar exploration history”.
“The mission has withstood the test of high temperature on the far side of the moon,” the CNSA said.
After lift-off, the module “entered a preset orbit around the moon”, it added.
The Chang’e-6 module touched down on Sunday in the Moon’s immense South Pole-Aitken Basin, one of the largest known impact craters in the solar system, according to the CNSA.
The probe’s technically complex 53-day mission began on May 3.
The Chang’e-6 features two methods of sample collection: a drill to collect material under the surface and a robotic arm to grab specimens above the surface.
After successfully gathering its samples, “a Chinese national flag carried by the lander was unfurled for the first time on the far side of the moon”, Xinhua said.
Scientists say the Moon’s dark side — so-called because it is invisible from Earth, not because it never catches the sun’s rays — holds great promise for research because its craters are less covered by ancient lava flows than the near side.
Material collected from the far side may better shed light on how the Moon formed in the first place.
Plans for China’s “space dream” have been put into overdrive under President Xi Jinping.
Beijing has poured huge resources into its space programme over the past decade, targeting a string of ambitious undertakings in an effort to close the gap with the two traditional space powers — the United States and Russia.
It has notched several notable achievements, including building a space station called Tiangong, or “heavenly palace”.
Beijing has landed robotic rovers on Mars and the Moon, and China is only the third country to independently put humans in orbit.
But Washington has warned that China’s space programme is being used to mask military objectives and an effort to establish dominance in space.
China aims to send a crewed mission to the Moon by 2030 and plans to build a base on the lunar surface.
The United States is also planning to put astronauts back on the Moon by 2026 with its Artemis 3 mission.
