Volcano 'hidden in plain sight' could help date Mars—and its habitability

Georgia Tech scientists have uncovered evidence that a mountain on the rim of Jezero Crater—where NASA's Perseverance Rover is currently collecting samples for possible return to Earth—is likely a volcano. Called Jezero Mons, it is nearly half the size of the crater itself and could add critical clues to the habitability and volcanism of Mars, transforming how we understand Mars' geologic history.
