How tall of a tower would you need on the rim of the crater to keep line of sight with the Earth?

Probably taller than we would want to carry down there.

Have an LSAM with a lot of extra juice in her to hover over a crater and drop one in.  ;)

These frozen orbits are not a brand-new discovery.  Chauncey Uphoff identified these lunar polar frozen orbits about ten years ago.
