These crazy little freaks are darn near unkillable.

known to be able to go for decades without food or water, to survive temperatures from near absolute zero to well above the boiling point of water, to survive pressures from near zero to well above that on ocean floors, and to survive direct exposure to dangerous radiations.

So, just for kicks, I guess, the European space chaps stuck some of these on the outside of a rocket that went into orbit for 12 days, then reentered. No problems, it seems.
