    An animated scene from "The Moon is a Harsh Mistress".

    Operation Hard Rock
    a 3:54 'vimeo'
    Animation inspired by 'The moon Is A Harsh Mistress' by
    Robert A. Heinlein. Commissioned by the late Bruce R.
    'Spike' MacPhee, this is a monument to his patronage
    of the Arts and a tribute to great Science Fiction.

    I seem to recall, that someone, somewhere, was saying that
    Heinlein's math was all wrong. And that throwing rocks at the
    Earth would not cause the political rethinking he wrote that
    it would. That these 'rocks' would not really be the
    equal of military weapons that would force Earth to give
    up rule.
    Any thoughts?

    Was Heinlein the originator of "Rods from God"? I can't speak to the math but I would think any semi-massive object flung from the moon to the Earth would be an incredibly destructive weapon. And no radiative fallout either. My only question would be
    accuracy. Could you terminally guide such a projectile at those velocities and hit a relatively small target such as Cheyanne Mountain?

    How accurate is a re-entry vehicle? I've seen a published claim of a CEP of
    100 meters, which I can neither confirm nor deny.
    The "Ninja" AGM-114RX9 can target a specific person, it's literally the
    bullet with their name on it.

    The Wiki credits Rods from God to Jerry Pournelle, from when he was a
    defense analyst, before writing sci-fi. In his Chaos Manor blog he deferred
    to Stefan Possony as the original source of much innovation. In an informal setting like lunch or a party ideas bounce around and several people may contribute improvements to the final product.
