Curiosity Finds Ancient Mars Rocks Deposited By Rushing Water

Carl Franzen of TPM:
NASA’s Mars Curiosity Rover has hit paydirt, discovering rock formations on the Red Planet that [were] most likely formed by the vigorous flow of a stream of water in Mars’ ancient history, NASA announced Thursday.

And somewhere, the shade of the late Carl Sagan is nodding and muttering, "Told you so!"

Water is only one of three items required for life to have ever existed on Mars. The other two are a source of carbon (for organic compounds) and an energy source. All must have been present simultaneously for life to have existed. None individually is evidence of earlier (or current) life on Mars. Even organic compounds, while suggestive of life, can be formed in space in a number of other ways. So we still have a lot of research yet to do.

There be cool pictures at the links above!


  1. karmanot, this one is almost the stuff of childhood fantasy... water on Mars, eons ago! It really is too bad that Sagan didn't live long enough to see this discovery; it would have meant a lot to him personally.

  2. When you mentioned Sagan, I could not but think of my Dad. During the year before he died, we would spend time discussing theoretical physics because he was searching for a way to be at peace with death. I started with Sagan's books as a departure point.
