I must have watched at least a dozen videos on using dispersion missiles and I can't for the life of me figure out what I'm doing wrong. Every time I find an asteroid that seems like it has sub-surface items I want to go get, I fire a dispersion missile and hold down the mouse button while it's in flight but the missile never actually drills. It just bounces right off the rock. I have fired over 200 of these suckers and not one ever worked. I heard somewhere there is an icon in the nav menu I should be looking at somewhere to guide me where to aim but I haven't been able to find that. Can someone walk me through how to actually aim and get these things drilling? Thanks!
