1 the amount of deflection does depend on ejecta which.... depends on your target. Different target, different ejecta. Btw, in my own research I have to deal with balancing momentum to measure the amount of ejecta so Im quite familiar with the concept 2 what part of this design is novel? We've already landed on asteroids, presumably its easier to hit them instead (since you don't care about matching the speeds) I dont think they were interested in "asteroid defense" at all [1]. Space weapons race is roaring and this was an excuse to spend money on it on a nominally civilian project. [1] given the literally astronomical odds of an asteroid hitting us, this is the last thing we should be worried about. CO2, nuclear weapons, desertification, men's sperm counts are all far far more likely to do us in
