    NASA does such cool small-scale things.

    Then the little voice in the back of my head says, “If it’s an asteroid big enough to be a threat to civilization, it’s going to take insane amounts of delivered energy to deal with it. On the order of build many factories on the moon, launch them by electromagnetic catapult, and have said factories manufacture hundreds/thousands of engines and fuel for same from local materials. Because that’s the only way you’ll deliver enough directed kinetic energy to do the job.”Report
