Ice may be hiding in the shadows of irregularities on the moon

Scientists are confident that water ice can be found at the poles of the Moon inside craters that are never illuminated

But observations show that water ice is also present on much of the lunar surface, even during daylight hours. 

In the new study, NASA updated its old model, making the moon's surface rougher and more convex.In fact, they used images from the Apollo missions: photos of boulders, craters that are actually on the surface of the Moon. 

Many computer models simplify the lunar surface by making it flat.If this were the case, the water ice could not be kept on the surface by the sun's rays for long. 

In the new work, the authors found that due tothe rough surface created shadows that allowed the water to be trapped and allowed to move as the day heats up and cools down again.

As the Sun passes the lunar day, surface ice canaccumulate in the shadows of the Moon, is exposed to sunlight and is hit by theThe water molecules then refreeze on the surface, accumulating as ice or frost in other hidden areas.Sun places.
