re, #4.

Odds are, something will impact. We have no way of predicting what the shot pattern would be. It's all very heroic and macho to talk about nuking something, but you'd have better control with a relative small kinetic impactor or a motor that makes a softish landing nudging the entire thing out of the way.

It's one thing to catch a bullet with your teeth. It is a completely different one to catch a load of buckshot with your teeth.
