Someday, one can only hope, scientists will finally figure out a way to send fish into space. Most likely, from a miniature launchpad somewhere at the bottom of the sea... However, before we even squeeze a trained astro-salmon into a tiny spacesuit (complete with a specially designed waterless breathing apparatus), strap him into that wee little rocket-powered spaceship and fire him out into the vast unknown... we really need to figure out how to light a match underwater.
