Discovery of flood deposits suggests early Mars had abundant water - science news - space

New evidence that planet Mars used to have water is provided by a recent study that analyzed the images of sedimentary rocks taken by Curiosity Rover.

The researchers identified four different units that represent different types of deposition in the sedimentary rocks. After analyzing the data, the scientists concluded this was the result of flooding.

Moreover, it appears that ancient Mars appears to have been very similar to Earth during Pleistocene (2 million to 12,000 years ago). This study adds to many others that suggest that Mars was covered in water in its early history.
