London
Times Online: The
Lunar Crater Observation
and Sensing Satellite (LCROSS) will blast two huge chunks
out of the lunar surface on Friday in order to have a closer
look at what the Moon is made of.The plume will be created by
dropping the Centaur upper stage of the rocket that fired
LCROSS to lunar orbit onto the surface near one of the lunar
poles.When the 2.4-tonne Centaur hits the ground, it will be
traveling at 2.5 km per second, and throw up a plume of debris
10 km high that can be analyzed by instruments on the LCROSS
spacecraft.
