A long time ago on a red planet far, far away, there used to be rivers1/19/2013
A few billion years ago, the red planet might have looked a lot more blue. New 3-D images of the Reull Vallis region of Mars, published by the European Space Agency, show what scientists say is a 932-mile long river bed. It's dried up now, of course, but between 1.8 billion and 3.5 billion years ago, there might have been water flowing throughout the region — at least until a glacier came through and reshaped the land. So make sure when you're planning your time travel vacation to Mars that you aim for the right year. There's nothing worse than packing for a nice Martian fishing trip and finding a glacier in the middle of your river. [Source]
