why don't we instead sent a nuke to deimos?
we barely have enough nuclear power to actually pull this off, we let a domino effect take place.
through advanced physics and trigonometry we calculate on how to veer off the small martian moon torwards phobos.
we detonate the super nuke and push deimos torwards phobos and let the 2 moons fall down torwards mars, the 2 moons together have enough power to equal the force that destroyed the dinosaurs and that put an end to a era.
mars will literally have its own new red spot and have a smouldering crater deeper than the mariana trench alongside unleashing the worst dust storm in the solar system, super heated dust that will melt the poles safely and make mars have a thicker atmosphere.
after its over which the worst will past after 4 years, we go and colonize there with better odds at inhabiting the martian world.
as a bonus we have free iron.
