NASA’s Mars Curiosity Rover Finds Signs of Life

    New information from NASA's Curiosity Rover suggests that Mars may once have had large, long-lasting lakes above ground. That would challenge the more popular theory that water on the planet was only underground, or only appeared in a few areas for a short amount of time.
NASA’s Curiosity rover has explored Gale Crater for 833 Martian days, or Sols. And it has found evidence, written in red rocks and sand, of lakes and streams on a warmer, wetter, habitable Mars.
The key to this latest theory is Mount Sharp, which stands 3 miles tall and sits in the red planet's Gale Crater. But Mount Sharp is a curious formation: The layered mountain is made of different kinds of sediment. Some layers were probably deposited by a surrounding lake bed, and other seem more likely to be the result of river or wind deposits.
