New photos indicate Mars had water more recently than thought

NASA (WKOW) -- The Mars Reconnaissance Orbiter has beamed back pictures from the Red Planet that indicate water may have been on the surface of there 800 million years later than previously thought.

Researchers have long suspected that Mars once sustained water on it's surface.  But they generally agree that most of the Martian atmosphere vanished around 4 billion years ago.

Determining that Mars' liquid-water heyday was still a good 3 billion years ago doesn't shake what we know about our galaxy right to the core. But it does potentially correct a 1-billion-year accounting error in the Martian timeline and could dictate some good landing zones for future rover missions as well as alter the way we go about seeking former life forms on out big red neighbor.
