Holy. Freaking. Crap.
I don’t think there is a better argument for continued efforts in space travel than the sheer gorgeousness of this video. Sure, you can talk all you want about scientific benefits, improved understanding of our world and the universe, not having all our eggs trapped in a single fragile basket, and so on. But I find the surge of awe and wonder engendered by this video to be far more inspiring than any of that.
Be sure to embiggen the video. It deserves your full screen.
