It looks to me like the center spot is a peak within the crater and the smaller white spots are material that's been ejected from the center spot.
Like John Belushi being a zit in the cafeteria in Animal House.

Looks like a huge sand boil.
Could it possibly be that the underlying subsurface material is being exposed by a big impact? The white may be ice or frozen CO2 that is the major constituent of the planetoid and the impact just removed enough of the outer surface to let it show. Any of the ice/CO2 that was ejected, sublimated away into space eons ago.................
