The Curiosity and NASA's other Mars rovers had to look for wide-open and flat landing locations to be on the safe side. Mars 2020, however, will have a camera-based navigation system capable of assessing terrains and reacting to potential hazards on the fly, allowing the rover to touch down on complex surfaces its predecessors have yet to explore. That camera is officially called Lander Vision System (LVS), and NASA has recently begun testing its capabilities. The space agency placed it aboard the flight test of an experimental rocket built by Masten Space Systems, a California-based aerospace startup. To be precise, LVS flew as part of a landing technology dubbed the Autonomous Descent and Ascent Powered-flight Testbed.
