"We can tell the story for a long history of volcanism and different mantle sources on the lunar far side," says Qiu-Li Li, a researcher at the Chinese Academy of Sciences in Beijing and a co-author of the Nature paper.
"Dust ranging from one to hundreds of micrometres in size contained a mixture of grains from different geological epochs," highlighting the diverse geological history recorded in lunar samples.
"The constant bombardment by micrometeorites and high-energy solar particles breaks up rocks into dust, which can then fly unimpeded by an atmosphere and land elsewhere," explains Yi-Gang Xu, a co-author of the Science paper.
