Thanks to the New Horizon spacecraft, humanity has been granted a close-and-personal peek at the rugged surface of Charon, Pluto's largest moon, for the first time in history. However, when getting to know an alien world, pictures aren't enough, right? Now NASA has upped the experience, providing an opportunity for the public to fly over the surface of the mysterious moon.
