What Don't We Know, What Might We Find?

What don’t we know about the Moon?

Lots, including:

•   What’s under the surface?
•   Why did nearly all the volcanic activity happen on the Nearside and not on the Farside?
•   How did water and other volatiles get there?
•   It doesn’t have a magnetosphere, so why are there large magnetic fields on the surface?
•   What happens at night? (Especially to the electrostatically charged surface). No human has been on the Moon at night nor during the 6 days per month when the Moon is in the Earth’s magnetotail.

What could we possibly discover on the Moon that we have not found on Earth?

Well, perhaps:

•          Gigantic networks of lava tubes. Larger than those on Mars and Earth.   
•       Although made from similar material, researchers believe that something (perhaps a proto-planet the size of Mars) hit Earth. We should be able to learn a lot about how the Moon and Earth formed from studying the mantle rocks exposed in Schroter Valley.   
•            Meteor strikes, some of which may be like none we have ever found before, such as those with an interstellar origin. For millennia the Moon and Earth have been bombarded by meteorites but Earth has atmosphere, erosion, weathering, and an active geologic system that recycles rock. Interstellar meteorites may have struck Earth over the millennia but have probably been “recycled” or buried at the bottom of an ocean and we will never find them. (Although there is a proposed hunt for one in the waters off the coast of Papua, New Guinea). On the Moon, with no oceans nor thick atmosphere to burn them up on the way in, the material could still be accessible right where it impacted.
