Things I learned today (when not doing serious physics stuff):
I knew about Laika and Ham but did not know that anyone attempted to train catstronauts. There is more information here. There seems to be some real confusion over the identities of Félix and Félicette, and which was the tabby and which was the black and white cat, but since I found a peer-reviewed article in Médecine aéronautique et spatiale which states that it was the female cat Félicette, I figure that must be true, and I thought you (especially Faunalia) should know that the French sent cats into space in 1963.
That is all.
