The Mars Curiosity rover has come across evidence of ancient flowing streams in several locations.
New photographs returned from the rover show exposed bedrock made up of smaller fragments cemented together, a geological phenomenon known as a sedimentary conglomerate. The size and rounded shape of the gravel indicates that the site would have once been home to a flowing stream of water, just like the streams we see here on the Earth.
Curiosity has been making its way to its first major science destination since landing on the Red Planet back in August. The team behind the rover hope to learn more about Mars' distant past and whether it was once capable of supporting life.
"Scientists theorize that the bedrock was disrupted in the past, giving it the titled angle, most likely via impacts from meteorites."
