I have always been an astronomy nerd ever since I was in middle school. I have spent countless nights in my back yard with my telescope and star chart, peering into the night sky with endless curiosity and wonder. I would gaze at the constellations wondering what was "out there" in space and marveling at our small place within the universe.
But what I truly found fascinating, almost more than space itself, was the astronauts who made it their livelihoods to explore the final frontier and adventure where no man has gone before. Astronauts can come from a variety of backgrounds, from air force pilots to engineers to medical doctors. They can have a passion for music, photography or even yo-yo tricks.
Of course astronauts are incredible scientists, but they are fascinating people as well, often with great life stories. So, here are 7 astronauts you should know about.
1. Don Pettit
Don Pettit is an awesome astronaut who has become known for his beautiful photography skills. He has also been known to make some pretty awesome YouTube videos, including one where he shows his cool yo-yo tricks in microgravity.
2. Mike Massimino
In addition to some pretty awesome cameos on The Big Bang Theory, Mike has written an awesome autobiography titled Spaceman, which I highly recommend. He has also made some fantastic appearances on Craig Ferguson's late night show.
