The rover is searching Yori Pass at the base of the Mars' Jezero Crater river basin for fine-grained sandstone that may have been carried by water.
for any signs that life once existed on the Red Planet — for any element, molecule, substance or feature that is characteristic of life.
"We often prioritize the study of fine-grained sedimentary rocks like this one in our search for organics and potential biosignatures," Perseverance deputy project scientist at NASA's Jet Propulsion Laboratory in California, Katie Stack Morgan, said in a ."What's especially interesting about the Yori Pass outcrop is that it is laterally equivalent with 'Hogwallow Flats,' where we found very fine-grained sedimentary rocks.
Stack Morgan said that the Yori Pass rock bed is similar to Hogwallow Flats — also called"the Bacon Strip" due to its light-colored striped rocks — because it is located at the same elevation and both have a large, traceable footprint which is visible on the Martian surface.
