Multi-temporal illumination map of the lunar south pole, Shackleton crater (19 kilometers diameter, or 12 miles) is in the center, the south pole is located approximately at 9 o'clock on its rim. Mapped area extends from 88°S to 90°S.

The spin axis of the Moon is tilted by only 1.54° (compared to Earth's 23.5°), leaving some areas near the poles in permanent shadow while other nearby regions remain sunlit for the majority of the year. One of the primary objectives of LROC is to unambiguously identify these regions.
