Samples from the rim of a 3.7 billion year old crater on Mars are the earliest evidence of water activity yet discovered, confirming previous findings that conditions existed on the now-rocky planet for life formation.
A group of rocks called the Matijevic formation suggested mild conditions on Mars billions of years ago, according to a finding from the National Aeronautics and Space Administration’s Opportunity rover, which touched down on the planet in 2004. The discovery was published today in the journal Science.
