The Lunar Reconnaissance Orbiter's Mini-RF has just completed its first month of systematic polar mapping. These mosaics cover from 70° to the pole for both the north (top) and south (bottom) polar regions. The left-hand images show radar brightness whilst the right-hand color images also show the circular polarization ratio.
These data will be analyzed to search for ice deposits in the floors of the permanently shadowed craters, as well as to learn more about the impact cratering process on the Moon. Larger image
