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.

The researchers discovered that the reflective features on the map match polar craters seen by Mariner 10 if the positions deduced from the spacecraft are about 1.5 degrees in error.

A spent rocket stage that NASA sent hurtling into the moon last year in hopes of kicking up water from a polar crater delivered on that mission, revealing that at least a moderate portion of its target was indeed made of ice.

On March 21, 2012, the MESSENGER team also revealed new supporting evidence that many permanently shadowed craters in Mercury's polar regions may harbor water ice insulated with a thin layer of soil or dust, or some other radar - reflecting volatile substance such as sulfur.

The most conspicuous feature on Vesta is a giant impact crater located around its south polar region, which is 310 miles (499 kilometers) across and nearly 12 miles (19 km) deep around a «bull's - eye» central peak rising 11 miles (or 18 km) above the exposed mantle rock of the crater floor — that is characteristic of rock rebounding from an impact.
