China landed an uncrewed spacecraft on the far side of the moon on Sunday, overcoming a key hurdle in its landmark mission to retrieve the world's first rock and soil samples from the dark lunar hemisphere.
The Chang'e-6 craft, equipped with an array of tools and its own launcher, touched down in a gigantic impact crater called the South Pole-Aitken Basin on the moon's space-facing side at 6:23 a.m. Beijing time (2223 GMT), the China National Space Administration said.
The mission "involves many engineering innovations, high risks and great difficulty", the agency said in a statement on its website. "The payloads carried by the Chang'e-6 lander will work as planned and carry out scientific exploration missions."
The successful mission is China's second on the far side of the moon, a region no other country has reached. The side of the moon perpetually facing away from the Earth is dotted with deep and dark craters, making communications and robotic landing operations more challenging.
Given these challenges, lunar and space experts involved in the Chang'e-6 mission described the landing phase as a moment where the chance of failure is the highest.
"Landing on the far side of the moon is very difficult because you don’t have line-of-sight communications, you’re relying on a lot of links in the chain to control what is going on, or you have to automate what is going on," said Neil Melville-Kenney, a technical officer at the European Space Agency working with China on one of the Chang'e-6 payloads.
"Automation is very difficult especially at high latitudes because you have long shadows which can be very confusing for landers," Melville added.
The Chang'e-6 probe launched on May 3 on China's Long March 5 rocket from the Wenchang Satellite Launch Center on the southern island of Hainan, reaching the lunar vicinity roughly a week later before tightening its orbit in preparation for a landing.
Chang'e-6 marks the world's third lunar landing this year: Japan's SLIM lander touched down in January, followed the next month by a lander from US startup Intuitive Machines.
The other countries that have sent spacecraft to Earth's nearest neighbor are the then-Soviet Union and India. The United States is the only country to have landed humans on the moon, starting in 1969.
