Permanent Shadows on the Moon
|
As the Earth and Moon orbit around the Sun, there are places on the Moon that never receive direct sunlight. Most of these permanently shadowed regions are at the lunar poles. This animation approximates the permanently shadowned regions pertaining to the Moon's south pole by maintaining a maximum sun angle to the surface of 1.5 degrees. These permanently shadowed areas are of interest because they could hold water ice. (NOTE: South Pole Digital Elevation Maps [DEM] based on publically released JAXA/Selene data.)
