On its way down, Perseverance will collect rocks to be retrieved by later missions.

In the 2030s, scientists plan to inspect this material on Earth.

For astrobiology, Perseverance's primary target is the delta in Jezero Crater.

A delta is formed when a river dumps silt and sand into a larger body of water. The river's sudden deceleration drops anything in suspension.
