NASA plans to take mini helicopter to Mars
NASA is looking into taking a heliciopter to scout Mars terrain. Sending the helicopter ahead the rovers to scout for destinations would be helpful for Mars rover missions. The atmosphere of the red planet is much lighter than Earth’s and the helicopter wouldn’t be as heavy there. [Sending a drone or a quadcopter will achieve the same with increased maneuverability, but that’s just us]
