NASA’s Curiosity rover has uncovered evidence that a Martian lake that existed long ago could have supported life.
It is estimated that the freshwater lake existed on the Red Planet about 3.7 billion years ago.
Curiosity’s lead scientist John Grotzinger says, “Quite honestly, it just looks very Earth-like… You’ve got an alluvial fan, which is being fed by streams that originate in mountains, that accumulates a body of water.”
The lake is positioned in a small area of Gale Crater, which the Curiosity Rover has been exploring since touching down on Mars in August 2012.
The ancient lake would have been about 30 miles long and 3 miles wide, and likely have existed for tens of thousands of years, based on the sedimentary deposits.
