Potentially Once-Habitable Ancient Lake Discovered on Red Planet
Scientists studying images from the U-of-Arizona-led High Resolution Imaging Experiment camera on NASA’s Mars Reconnaissance Orbiter have discovered a possibly once-habitable ancient lake on Mars at a place called Holden crater (NASA image).
Mars’ placid Holden crater lake are topped with layers of great boulders, apparently left by water flooding the Holden crater rim and eroding the older lake sediments.
The Holden crater lake could have been larger than Lake Huron, holding an estimated 4,000 cubic kilometers of water.
“The volume of water that poured through during this flood must have been spectacular,” said John Grant of the Smithsonian National Air and Space Museum.
