"Massive Asteroid Impact: 2 Billion Craters on Mars Revealed"

A giant asteroid impact on Mars 2.3 million years ago created a massive crater called Corinto and around two billion smaller individual craters across a 1,000-mile region. The impact, one of the biggest seen on Mars, left behind a vast field of destruction, with secondary craters ranging in size and shape. Data from NASA's Mars Reconnaissance Orbiter was used to study the impact and its aftermath, revealing insights into the composition of the ejected material and the potential presence of water or ice at the impact site.
