New said the data will be about 1,000 times better than any other measurements of lunar gravity, explaining that such data can be processed to
peer beneath the moon's surface and locate any significant structures related to early lunar history.
I see a lot of talk in the John Lear forum about just how strong the gravity is on the moon. If NASA is going to spend all of this money on new craft
for gravitational measurements, then one question comes to my mind.
How reliable was the original data?
Another interesting quote from Micheal New, the lead project scientist,

"The other thing that may become a little clearer will be a little bound on the size of any lunar core, if there is one."
