LOS ALAMOS, N.M. – New findings show bodies of water likely existed on the surface of the Mars in its early history.

The findings include long-lasting lakes that built up deposits at least 250 feet deep.

The findings are based off of images from NASA’s Curiosity rover.

“Skeptics have often asserted that evidence of water on Mars could be attributed to ephemeral, local wet episodes,” said Scientist Roger Wiens from Los Alamos National Laboratory. “But based on these images from Curiosity, we know that, in fact, Mars had a rainy and snowy environment billions of years ago for an extended period of time.”

Curiosity has been exploring Gale Crater since August 2012. provides commenting to allow for constructive discussion on the stories we cover.
