New research from NASA's Lunar Science Institute indicates that the solar wind may be charging certain regions at the lunar poles to hundreds of volts.  In this short video Dr. Bill Farrell discusses this research and what it means for future exploration of the Moon's poles.    New research from NASA's Lunar Science Institute indicates that the solar wind may be charging certain regions at the lunar poles to hundreds of volts.

This animation shows conceptually how solar wind might create electrically charged ambipolar environments in certain regions at the lunar poles.  See the short video above for more explanation of this process.
