I hope the MER are old enough to remember how to "duck and cover". unsure.gif

I don't think you have to worry about that just yet.

I have a feeling we're all lining up for a big disappointment here. Suppose the impact odds come up to 1/10 and then be completely ruled out. Talk about an anticlimax...

Still, Shaka's observation raises an interesting question: how many (if any) of you would be willing to sacrifice (or, rather, consciously put at risk of destruction) one of the rovers in exchange for being able to witness an event this rare (and not necessarily witness it by the rover itself)?
