Hey, Ken! Moonlight if you have to.
Ken?
I know you love space-travel/exploration, and all that goes with it.
Try this approach!
Find a mundane, down-to-earth job [for starters] that "pays the bills and pays for your groceries."
Then "moonlight" [either for whatever they'll pay you, and if not, as
a volunteer] for one of the
promising commercial, private space-endeavors. i.e, "One of the X-Prize corporate-contestants, or
MirCorp, Bigelow, etc..."
Hope this helps.
Good luck.
Jake
