Subsequent images from two telescopic cameras on Mars Reconnaissance Orbiter revealed craters within this impact scar that had not been present in January 2012. The largest of these craters -- 159 feet (48.5 meters) wide -- is the biggest fresh impact crater ever clearly confirmed anywhere with before-and-after images.
These two MARCI images are centered at 3.34 degrees north latitude, 219.38 degrees east longitude.
MARCI is one of six instruments on NASA's Mars Reconnaissance Orbiter. The camera was built and is operated by Malin Space Science Systems, San Diego. NASA's Jet Propulsion Laboratory, a division of the California Institute of Technology in Pasadena, manages the Mars Reconnaissance Orbiter Project for NASA's Science Mission Directorate, Washington.
