One ton of the moon’s surface might yield 32 ounces, NASA scientists said. Scientists believed the moon was dry when the Apollo missions started in the 1960s.
Scientists at Brown took another look at images of the moon’s surface retrieved from the Moon Mineralogy Mapper, an imaging spectrometer that flew aboard India’s Chandrayaan-1 lunar orbiter in 2008.
After developing a “Thermal correction” that separated the readings of reflected light and heat, scientists were able to collect data showing evidence of the glass beads in nearly all the volcanic deposits spread across the moon, Brown said.
“Although the amount of water found by the authors is significant in terms of our understanding of the moon and how we model the lunar interior, it is still a very small amount, around 0.015% of the soil.”
Scientists think the moon was created by debris left behind when a planet-sized object slammed into the Earth, Milliken said.
“The growing evidence for water inside the moon suggests that water did somehow survive, or that it was brought in shortly after the impact by asteroids or comets before the moon had completely solidified,” Shuai Li, a co-author of the research and a postdoctoral researcher at the University of Hawaii, said in the news release.
