As expected, the researchers found that the fine dust — ranging from one to hundreds of micrometres in size — contained a mixture of grains from different geological epochs. 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.
