I'm a huge space enthusiast, and love learning about the universe and our place in it. I mean, it's where we came from. Elaborating on Sagan's "We are star stuff" type quote, the heavier elements in our blood, like Iron, were only produced inside of other stars during the fusion process, and only exist here and in use because those stars died, exploded, and later formed a new generation of stars with planets around them. This little blurb by NDT during one of his speeches expresses how I feel, and how looking up at the stars is almost spiritual for me. The first 5 minutes or so of this video kind of sums up my thoughts quite eloquently...

As a result I'm obsessed with space exploration, and more importantly manned space exploration... which hasn't really done too much yet, but we're working on it. And the scientists and engineers like Von Braun or Elon Musk that are working on getting humans out into our universe are very inspiring for me.

It's what gives me hope for our species, yet many people don't seem to give a shit about it.
