The trick is that we want to find out if it's really water that we're mapping,

Clearly I'm going to crash the spacecraft anyway, ... We're trying to do the most useful thing scientifically.

Then we don't have to say that we infer water, ... We will know that it's water that we found.

The moon will become the New York City of the Earth complex in the future,

We had a tantalizing indication (after Apollo) of what the global structure of the moon was but when you've only seen 20 percent maximum of the surface, you don't know what you've got, ... Now we know exactly what's going on. This is a big jump forward.

It got 10 times more data than was expected. It has flown perfectly,
