Chinese scientists find high water content in lunar soil samples
Chinese scientists have found high water content in lunar soil samples brought back by the Chinese probe “Chang’e-5”, according to a study published in the journal “Nature Communications”.
The study was conducted by a research team from the Institute of Geochemistry of the Chinese Academy of Sciences.
Through infrared spectroscopy and nanoscale secondary ion mass spectrometry analyses, the team found a large amount of solar wind-derived water on the mineral surface of the samples, estimating at least 170 parts per million of water content. has its source from solar wind protons injected into the lunar soil.
The results of spectral and microstructural analyzes prove that the formation and storage of water originating from the solar wind is mainly influenced by exposure time, crystal structure and mineral composition.
This study showed that lunar surface minerals are important “reservoirs” of water, providing an important reference for the distribution of water in the mid-latitude region of the lunar surface.
Chinese scientists have discovered a new mineral – “Changesite-(Y)” – in lunar samples brought back by Chang’e-5. The discovery was released jointly by the National Space Administration and the China Atomic Energy Authority on Friday.
