Points to consider:
a. The polar regions of the Moon receive almost continuous sunshine because the inclination of its axis of rotation (i.e., its axial obliquity) is only 6.68° compared to 23.45° for the Earth.
b. Sunlight is an important source of heat, light, and energy.
c. Deep impact craters in the polar regions are in perpetual shade which may have allowed water ice released by impacting comets to have accumulated there.
