Mapping info of Luna’s gravity field is out.  And very pretty!

I did not realize that the moon had much differentiation in its components.  They say in the piece that the moon’s crust is about 6 miles thick.  What’s below the crust?  I thought we decided that the moon was made mostly of material from earth’s crust.  So what’s going to be different below the peel?
