The lunar south pole is of special interest to scientists because of the postulated occurrence of ice in permanently shadowed areas. Of the lunar poles, the south pole is of greater interest because the area that remains in shadow is much larger than that at the north pole. The lunar south pole craters are unique in that sunlight does not reach the bottom. Such craters are cold traps that contain a fossil record of the early solar system.

Famous quotes containing the words lunar, south and/or pole:
“A bird half wakened in the lunar noon
Sang halfway through its little inborn tune.”
—Robert Frost (1874–1963)
“...I believe it is now the duty of the slaves of the South to rebuke their masters for their robbery, oppression and crime.... No station or character can destroy individual responsibility, in the matter of reproving sin.”
—Angelina Grimké (1805–1879)
“This man was very clever and quick to learn anything in his line. Our tent was of a kind new to him; but when he had once seen it pitched, it was surprising how quickly he would find and prepare the pole and forked stakes to pitch it with, cutting and placing them right the first time, though I am sure that the majority of white men would have blundered several times.”
—Henry David Thoreau (1817–1862)
