In addition to analyzing rock formations, they also will determine that the findings Curiosity is part of the riverbed that once existed on Mars. Researchers identified several sites on Mars, where Curiosity has captured images that site during the first 40 days mission.

Scientists say, one of the three stones that resemble asphalt, which is called the 'Goulburn' is really the next Curiosity landing site. While two other stones, 'Link' and 'Hottah' is approximately 50 and 100 meters from the Curiosity landing site.

of the Planetary Science Institute reveals, ancient riverbeds on Mars exactly on Earth.

He explained that there are many signs that rock and gravel that exists on Mars is an ancient riverbed. Researchers looked up 515 stone and gravel. Large pebbles grouped, showing movement and then followed by some sand like on Earth.

With the arrangement of pebbles and small stones at the size of these, the scientists determine the speed of the former ancient river system is approximately one meter per second. Scientists also estimate the depth of this ancient river must reach the ankle or hip adult humans.
