Will we, the human race, take BTC and other blockchain tech with us in space? I'm sure we will. When we literally go to the moon, and to mars, etc., what role will Bitcoin serve?
the answer to your question is a little futuristic and a bit science fictiony!
we can bring bitcoin as a currency to other planets as soon as we actually went to those planets and also we could colonize these planets! right now an astronaut going to outer space does not need a currency! they are not shopping up there to need it
and i am sure by them the form of currency has already changed into crypto.
