Thin-slice? How about electron microscopy? Seems to me that they had to resort to such high magnifications to see what appear to be microfossils in that Martian meteorite. If all the little critters on Mars grew that small (not an unreasonable conjecture, given the harsh conditions and lower average energy levels in the environment), we'll need a rover that can prepare samples for, and subject them to, electron microscopy.
Sounds like a real challenge. Especially considering that there were plans (a long time ago) to provide Apollo astronauts *on the lunar surface* with equipment to make thin rock slices (part of the two-week lunar stay, dual-launch proposals for extended Apollo landings). So, I think that there are lots harder things to do, even remotely, than making and observing thin slices...  -the other Doug -------------------- “The trouble ain't that there is too many fools, but that the lightning ain't distributed right.” -Mark Twain
