Looking at the HiRISE imagery of the descent stage, does the distribution of the debris field represent the disintegration of the stage from impact only, or is it possible that some or all of the 140+/- kilos of Hydrozine exploded and expanded the debris field? [I understand the darker albedo material is from below the surface]

Does the thin martian atmosphere contain enough oxygen to support combustion/explosion? [guessing No, but my chem is insufficient]

Were the hydrazine cells sufficiently designed to survive impact intact?

I couldn't find anything on the net or in the specs, any ideas?
