I live in an expensive suburb right next to a wood. Field rats dug a tunnel under my garbage shed. Had to demo the shed and get a fully contained shed from Costco. Now, I have field mice that winter in my attic. Didn’t know brick homes have weep holes. I put a few jars of pepper mint oil up there. And filled the weep hole with copper wool. Not to mention the other critters that stop by like: squirrels, raccoons, skunks, chipmunks, groundhog, deers, stray cats, lizards, newts, shrews, and coyotes.

Mining the moon was never a loony idea. If you wanted to construct large structures in earth’s orbit the the moon is the cheapest place to get the metals needed because it takes 25 times less energy to get stuff from the moon to earth’s orbit than to get it from the earth surface. You don’t even need a rocket. You can use a mass driver to fling the material from the moon to earth’s orbit.

The reactor is at the other end of the rocket far away from the payload in the high radiation environment of space. At worse, a small block of material should be enough of a shield. The radiation will dissipate at square the distance from the reactor. Then it had to penetrate the liquid hydrogen in the tank. As for the tank, a shiny thin Mylar sheet would be enough to reflect the rays of the sun. The Vacuum of space makes for a perfect insulator.
