China's Lander Has Detected Water on the Moon - By Nancy_A
China’s Chang’e-5 lunar lander has found evidence of hydroxyl on the Moon. Hydroxyl is a close chemical cousin of water, H2O. While several other orbital missions have detected OH on the Moon previously, Chang’e-5 marks the first time it has been detected by a spacecraft sitting on the lunar surface.brought a sample of lunar regolith back to Earth in December of 2020
. However, for the detection of hydroxyl, the Chang’e-5 lander used instruments on board to look at the area around the landing site. Scientists were able to use data from a panoramic camera, lunar mineralogical spectrometer and lunar penetrating radar to look for evidence of water molecules. Curiously, a rock near the landing site contained the most hydroxyl, almost twice as much as the surrounding regolith. The regolith has less than 120 parts per million of water molecules, while the rock has about 180 ppm.“The spectrum of CE5-Rock exhibits a strong absorption 2.
An international team of scientists led by researchers from the Chinese Academy of Sciences in Beijing published their paper in the journal Science Advances.
