The Chinese Academy of Sciences recently studied 17 lunar regolith (loose fragments of rock and glass) samples brought back to Earth by the Chang'e-5 lander. The tests revealed that the samples were more hydrogen-rich than those returned by Apollo missions. Researchers believe that solar winds- a continuous stream of charged particles emitted by the Sun- might have embedded hydrogen molecules in lunar soil.
