Wasn't it boulders like laying around on the asteroid? Held there by microgravity, and thus knocked in all directions at the impact?
I mean debris from the impact, yes, "boulders" laying around, no I didn't expect that :-)
OK. Then. I guess the summary would be like, the asteroid was more loose than we though, and we had no idea how the boulders got ejected from the surface because our impact.
