Hong Kong PolyU to study water in lunar soil samples

Hong Kong Polytechnic University plans to use lunar soil samples retrieved by the Chang'e 5 spacecraft four years ago to analyze the moon's water resources, with insights expected to bolster research on surface conditions and support further human space exploration missions.

The university obtained a surface soil sample weighing 400 milligrams from national space authorities, as well as a subsurface soil sample totaling 42.6 milligrams, researchers said at a news conference on Wednesday.

The Surface Sampling and Packing System the university developed assisted in the collection of lunar soil samples by Chang'e 5 in 2020 and Chang'e 6 this year.
