TAMPA, United States – Scientists said Tuesday they have confirmed the existence of ice on the Moon’s surface for the first time, a discovery that could one day help humans survive there.
Signs of ice on the Moon have been reported by scientists for years, but previous observations could have been explained by other phenomena, such as unusually reflective lunar soil, the study authors said.
“This is the first time scientists have definitive evidence for the presence of water ice on the surface,” lead author Shuai Li of the Hawaii Institute of Geophysics and Planetology told AFP.
The ice mainly lies in the frigid shadows of craters at the lunar poles, and was detected using instruments that flew on the Chandrayaan-1 spacecraft, launched in 2008 by the Indian Space Research Organization.
Using data from NASA’s Moon Mineralogy Mapper (M3) instrument, researchers identified three chemical signatures “that definitively prove there is water ice at the surface of the Moon,” said a NASA statement.
