Detailed explanation-1: -A study published in Science analyses multiple rocks found at the bottom of Jezero Crater on Mars, where the Perseverance rover landed in 2020, revealing significant interaction between the rocks and liquid water. Those rocks also contain evidence consistent with the presence of organic compounds.

Detailed explanation-2: -NASA’s Perseverance Mars rover took this selfie near rock nicknamed “Rochette, ” found on Jezero Crater’s floor, on Sept. 10, 2021, the 198th Martian day, or sol, of the mission. The rover found that Jezero Crater’s floor is made up of volcanic rocks that have interacted with water.

Detailed explanation-3: -Jezero Crater sits within the Isidis Planitia region of Mars, where an ancient meteorite impact left behind a large crater some 750 miles (1, 200 kilometers) across.

Detailed explanation-4: -The delta in Mars’ Jezero Crater is an area where scientists surmise that, billions of years ago, a river once flowed into a lake and deposited rocks and sediments in a fan shape. Deltas are believed to be the best places on Mars to search for potential signs of ancient microbial life.

Detailed explanation-5: -NASA’s Perseverance Mars Rover has arrived at an ancient delta in Jezero Crater, one of the best places on the Red Planet to search for potential signs of ancient life. The delta is an area where scientists surmise that a river once flowed billions of years ago into a lake and deposited sediments in a fan shape.
