"Scientists are priming two spacecraft to slam into the moon's South Pole to see if the lunar double whammy reveals hidden water ice."
"LCROSS researchers anticipate a more than a 90 percent chance that the impactors will find some form of hydrogen at the poles. The off-chance exists that the impactors will hit a newer crater that lacks water-yet scientists can learn about the distribution of hydrogen either way."
" ' We take [what we learn] to the next step, whether it's rovers or more impactors,' Colaprete said."
LCROSS stands for Lunar Crater and Observation Sensing Satellite and Tony Colaprete is "the principal investigator for the mission at NASA's Ames Research Center in Moffett Field, Calif{ornia.}"
