China is set to launch a probe to collect samples from the far side of the moon, in what is being billed a world first.
An unmanned rocket carrying the Chang’e-6 probe is due to lift off from the Wenchang Space Launch Center just before 17:30 local time (10:30 BST).
The 53-day-long mission aims to bring around two kilograms of lunar samples to Earth for analysis.
It will try to re-launch from the side of the moon facing away from Earth.
This is described as the dark side of the moon because it is invisible from Earth, not because it does not catch the sun’s rays.
Ge Ping, vice director of China’s Lunar Exploration and Space Engineering Center, told reporters ahead of the launch: “Chang’e-6 will collect samples from the far side of the Moon for the first time.”
The probe was named after the Moon goddess and one of the most popular figures in Chinese mythology.
It is expected to land in the South Pole-Aitken Basin, which is some 2,500km (1,553 miles) wide and up to 8km (5 miles) deep.
It then aims to collect lunar soil and rocks, and conduct experiments.
The launch marks the first of three high-wire unmanned missions to the moon planned by China this decade.
Chang’e-7 will search the lunar south pole for water, and Chang’e-8 will attempt to establish the technical feasibility of building a planned base, known as the International Lunar Research Station.
Its predecessor, Chang’e-5, retrieved the youngest ever lavas from the moon on its return in December 2020.
Friday’s lift off will mark the latest stage in China’s space exploration programme that is competing with the US.
Five years ago China became the first country to land a rover on the moon’s far side.
By 2030, it aims to have put its first astronauts on the Moon, and to have sent probes to collect samples from Mars and Jupiter. – BBC
