New evidence of ancient ocean on Mars
Posted: Tue, Jun 15, 2010, 7:29 AM ET (1129 GMT)
A recently-published study provides additional evidence that an ocean covered as much as one third of the surface of Mars early in its history. The study, published Sunday in the journal Nature Geoscience, studied river valleys and delta deposits mapped on the planet by several spacecraft. They found that over half of the delta deposits they studied were at the same elevation, suggesting they fed into a common ocean that covered much of the planet's northern hemisphere. The study also identified 40,000 river valleys on the planet, four times the number previously identified.
