That trip took 17 million years according to the Wikipedia article. Seems a bit long for anything to survive, surely?

We have pulled living bacteria out of sediment 100 million years old so 17 million years is nothing. More importantly this is just the time for this particular meteorite - people have done the calculations and some meteorites do the trip in around a year.

Woah, amazing.

Here's a fun article about reviving supposedly 250 million year old spores trapped in salt crystals: http://www.its.caltech.edu/~bi1/Bi1__Micro-_to_Macro-Biology...
