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?
