This is a very exciting result. It's the first demonstration that animals can survive a reentry event similar to what would be experienced inside a meteorite. It shows directly that even complex small creatures originating on one planet could survive landing on another without the protection of a spacecraft.

I can't say I was surprised the worms were alive, because we spin them up to 2,000 G's in the lab without thinking about it. What surprised me was that they found the canisters at all.
