Using data gathered by NASA's Lunar Reconnaissance Orbiter (LRO) mission, scientists believe they have solved a mystery from one of the solar system's coldest regions — a permanently
shadowed crater on the moon.
Permanently
shadowed craters on the moon are among the coldest known places in the solar system and have long been suspected to hide significant water deposits, a potential resource for future lunar outposts.

Discovering molecular hydrogen
on the
moon was a surprise result from NASA's Lunar
Crater Observation Sensing Satellite (LCROSS) mission, which crash - landed the LCROSS satellite's spent Centaur rocket at 5,600 miles per hour into the Cabeus
crater in the permanently
shadowed region of the
moon.
Many scientists think these permanently
shadowed regions, such as the floors
on impact
craters in the
Moon's polar regions, could hold large deposits or water ice.
Since the 1960's scientists thought that only in permanently
shadowed areas in
craters near the lunar poles was it cold enough to accumulate this volatile material, but recent observations by a number of spacecraft, including LRO, suggest that hydrogen
on the
moon is more widespread.
Water
on the
moon, if it exists at all, is probably confined to frozen deposits in a few
shadowed craters near its poles.
As is the case with viewing the
moon's terminator line, the change in light casts
shadows, allowing viewers to see many features in three dimensions (like being able to see the depth of
craters on the
moon).
He first used it to observe the
moon and see the
shadows cast by its mountains and
craters; he went
on to catalogue sunspots; and he discovered the four largest
moons of Jupiter — Io, Europa, Ganymede and Callisto — that are now known as the Galilean
moons in his honor.
PREDICTION 47: As has been discovered
on the
Moon and apparently
on Mercury, frost, rich in heavy hydrogen, will be found within asteroids and in permanently
shadowed craters on Mars.
