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? |

Methinks if we ever use a skycrane type of landing again, we're going to have to program a little more smarts into the descent stage and have it either fly farther away or try to kill its velocity before it crashes. I shudder to think of what might have happened had one of those fragments of descent stage come back and whanged the rover real good...

With an estimated 140Kg of prop left, they should be able to add this in for the next attempt, whenever that might be. |
