China says its Chang’e-6 mission successfully landed on Moon’s far side
Chinese state media described the successful landing as an “historic moment”.
The state broadcaster said “applause erupted at the Beijing Aerospace Flight Control Center” when the Chang’e landing craft touched down on the Moon early on Sunday morning.
The lander should spend up to three days gathering materials from the surface in an operation the CNSA said would involve “many engineering innovations, high risks and great difficulty”.
“Everyone is very excited that we might get a look at these rocks no-one has ever seen before,” explains Professor John Pernet-Fisher, who specialises in lunar geology at the University of Manchester.
He has analysed other lunar rock brought back on the American Apollo mission and previous Chinese missions.
But he says the chance to analyse rock from a completely different area of the Moon could answer fundamental questions about how planets form.
Most of the rocks collected so far are volcanic, similar to what we might find in Iceland or Hawaii.
But the material on the far side would have a different chemistry .
“It would help us answer those really big questions, like how are planets formed, why do crusts form, what is the origin of water in the solar system?” the professor says.
The mission aims to collect about 2kg (4.4lb) of material using a drill and mechanical arm, according to the CNSA.
The South Pole–Aitken basin, an impact crater, is one of the largest known in the solar system.
From there, the probe could gather material that came from deep inside the lunar mantle – the inner core of the Moon – Prof Pernet-Fisher says.
The Moon’s South Pole is the next frontier in lunar missions – countries are keen to understand the region because there is a good chance it has ice.
