NASA's Perseverance rover preparing to land on Mars

The countdown has begun as NASA's Mars rover Perseverance prepares to land on the red planet.
Scientists picked the 28-mile-wide crater after a five-year study of more than 60 potential sites, as they believe the crater was once flooded with water and home to an ancient river delta more than 3.5 billion years ago. Landing on Mars is risky and around half of all previous Mars landing attempts have succeeded. Jezero Crater's topography -- which also includes cliffs, sand dunes and boulder fields -- only increases the difficulty of the mission.More Related News
