Dr. Anthony Colaprete (NASA Ames Research Center)
In 2009, NASA purposely crashed two spacecraft into one of the Moon's polar regions. The impacts raised a huge plume of material, visible even to smaller telescopes on Earth. Speaking before the mission took place, Dr. Colaprete, the Principal Investigator for it, fills us in on why scientists believe there is water in deep craters at the Moon's poles and how the LCROSS mission planned to look for it in the plume.
