    • Of course, knowledge of the lunar surface needs to be coupled with the engineering capability of precision navigation, descent, and landing.

    • Radar observations of the lunar polar regions yield conflicting interpretations regarding the presence of high-backscatter regions that could be indicative of water ice (77,78). Neutron spectroscopy from Lunar Prospector (19) shows the presence of hydrogen in both near-polar craters and various other parts of the Moon, and could correspond to either water or hydrogen nuclei implanted by the solar wind (2O).

    • Because the Moon's spin axis is tilted only 1.5°, high elevation points at the poles may be illuminated year-round.
