Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that Tardigrades survive exposure to the vacuum of outer space?

Yes. Multiple sources, including Wikipedia's space-tardigrade article and a NASA podcast interview, state that tardigrades survived exposure to the vacuum of space in the 2007 FOTON-M3 mission, with dehydrated samples reanimated afterward. Several peer-reviewed reviews and papers also list vacuum-of-space tolerance among tardigrade extremes.
