NASA’s Curiosity Rover has discovered evidence on Mars that suggests underground water once existed in a region of the planet later than scientists first believed, the agency reported March 15.
“Our findings show that Mars didn’t simply go from wet to dry,” said Dimitra Atri, group leader of the Mars Research Group at New York University. “Even after its lakes and rivers disappeared, small amounts of water continued to move underground, creating protected environments that could have supported microscopic life.”
