- sudosysgen 6y agoThis is a game of energy. The energy necessary to deflect an asteroid from earth is undoubtedly lower than to put it on that course to begin with. It's really not MAD. Also, sending a nuke could be done much faster than an asteroid intercept mission. It could get there in as little as a week.
- myrandomcomment 6y agoPutting a few 100 rocks on course for earth all with different trajectories and arrival times is quite a doomsday game. Mars could be nuked but with 100s of big rocks, a few are going to get though and it will take only a few. It is MAD.
- sudosysgen 6y agoThey need to be massive enough to do some real damage, and this will require a lot of energy and luck to divert as there is a low chance you'll find a few hundred on such a trajectory. Just getting the ships in position to shift their orbits will take weeks to months. Meanwhile, nukes already hit. You'd only need 100km/s of delta-v, which is very doable at those timescales with a sub-ton payload.
