Home NASA’s Perseverance rover used its Mastcam-Z instrument to capture this 360-degree panorama of a region on Mars called “Bright Angel,” where an ancient river flowed billions of years ago. “Cheyava Falls” was discovered in the area slightly right of center, about 361 feet (110 meters) from the rover.

NASA’s Perseverance Mars Rover Uncovers Arrowhead-Shaped Rock with Possible Signs of Ancient Martian Life -4
As shown in this graphic, astrobiologists catalog a seven-step scale, called the CoLD (Confidence of Life Detection) scale, to research whether a sample could indicate life. This “Cheyava Falls” sample is an example of Step One: “Detect possible signal.” Much additional research must be conducted to learn more. (NASA/Aaron Gronstal)
