Geology of a Formerly Wet Planet at the Mars Perseverance Rover Landing Site

On the afternoon of February 18 (Earth time here in Ohio), NASA's most ambitious and sophisticated rover will hopefully land on Mars to start years of exploration around Jezero Crater. Much like NASA's other rover missions -- Spirit, Opportunity and Curiosity -- the main goal of the Perseverence mission is to understand the Martian geologic past and potentially find evidence of past life on our next neighbor out in the solar system.
