Impact on Mars

Mars has a thin atmosphere – just 1% as dense as Earth's. As a result, there's less of a protective barrier to burn up space debris. That means larger meteors make it through the Red Planet's atmosphere than Earth's. CTX has detected over 800 new impact craters during MRO's mission. After CTX spotted this one, scientists took a more detailed image with HiRISE.

The crater spans approximately 100 feet (30 meters) in diameter and is surrounded by a large, rayed blast zone. In examining the distribution of ejecta – the debris tossed outward during the formation of a crater – scientists can learn more about the impact event. The explosion that created this crater threw ejecta as far as 9.3 miles (15 kilometers).
