English: Curiosity and Descent Stage, Artist's Concept

This is an artist's concept of the rover and descent stage for NASA's Mars Science Laboratory spacecraft during the final minute before the rover, Curiosity, touches down on the surface of Mars.

The descent stage will provide rocket-powered deceleration for a phase of the arrival at Mars after the phases using the heat shield and parachute. The descent stage also carries the radar system providing a stream of information about the spacecraft's altitude and velocity. As it nears the surface, shortly after the moment depicted here, the descent stage will lower the rover on a bridle and deliver it to the ground.
