A NASA radar system onboard India's lunar orbiter has spotted evidence of water -- a lot of water -- on the moon's north pole.
The space agency announced Monday that scientists have discovered about 600 million metric tons of water ice
in more than 40 craters on the lunar surface. The craters, which are in permanent shadow and extremely cold, range in size from one to nine miles in diameter. NASA scientists have long theorized that the dark, cold craters held one of their best chances of finding water ice on the moon.
"After analyzing the data, our science team determined a strong indication of water ice, a finding which will give future missions
a new target to further explore and exploit
," said Jason Crusan, a program executive for NASA's Space Operations Mission Directorate, in a statement.
