I'd hate for my optimistic ramblings to be imposed on any MSNBC readers. Try for someone who does this for a living and get more than just a qualitative guess.

I've worked with ToF-SIMS analyzing silicon wafers implanted with energetic atoms but I'm not an expert. I don't see how even this
crash (190 mph) could change the depth profile of energetically implanted atoms in the various substrates. Most of the solar wind is not very energetic (a few eV) and may be contaminated due to shallow sample depth, depending on the severity of the disruption. The gold foil might be the best bet if there are pieces that buckled and folded on themselves.

All bets are off if the samples were touched by some agent (Hydrazine/NTO?) that could vigorously alter the surface of the
samples.
