Not where the Apollo missions landed. The Scientists believe that the ice only exists in the regions that do not ever see sunlight, like in the bottoms of shaded craters at the poles. There is effectively no atmosphere on the moon, so as soon as it is exposed to sunlight, it evaporates/sublimates, and (I think) is gone 'forever'. So I believe the deal is that any ice that is still there has been there for a very long time, and never exposed to sunlight.
The Apollo missions landed on the lit portions of the moon. If there was ice there at all, it would have probably been buried deep underground, too deep for the Astronauts' core samples to get to. But then again, I am not a Scientist, just an Engineer, so I am certainly no expert on Lunar ice theory
. As usual with space exploration, no one knows for sure until probes are sent, and even then the data may be uncertain and open to debate and speculation.
The LCROSS lunar impact is not until August IIRC, exact time and date TBD
later depending on which crater they end up targeting.
The NASA Channel is covering the launch BTW. I am at home watching it now, channel 283 on DirecTV
