ESA's Mars Express radar gives strong evidence for former Mars ocean


Appears Doctor Who was right. Again.

ESA news article, "Mars Express radar gives strong evidence for former Mars ocean," provides some pretty good food for thought about the past existence of water on Mars and even an ocean. Two oceans have been proposed:
"4 billion years ago, when warmer conditions prevailed, and also 3 billion years ago when subsurface ice melted."
The scientists are careful to detail that they don't think this second ocean existed for long enough for life to have developed, but its nice that they are not ruling out the possibility that further data collected on the first ocean might yield different results.

That being said, John Carter anyone?
