A little shot of optimism from our favorite astronaut Chris Hadfield.

I love this guy.

And I appreciate hearing such hopeful talk from a man who has seen this planet from a perspective that few others will ever experience.

We are moving forward, getting better, and improving our lives.

There are many battles yet to wage, and adversaries yet to defeat, but what we have learned is that in the end those who are moving us forward leave those trying desperately to stop us dead or turn us back in the dust.

Perhaps the coolest cover of David Bowie's "Space Oddity" that you will ever see.

This is Commander Chris Hadfield on board the International Space Station doing a rather amazing, and genuinely good, rendition of Space Oddity.

So much awesome in this video.

It's official. Everything is cooler at zero gravity.

I think Space Station Commander Chris Hadfield has too much fun at his job.

I think I'm jealous.
