   I've wondered what the effect would be of putting pairs of ice bodies   
   into close flyby trajectories either side of Mars, aimed so they   
   collide. Say aim one over the north pole, one over the south and get a   
   big bang over the equator. Hopefully you get a big cloud of steam with   
   insufficient velocity to stay up...
