Testing and iterating, the secret sauce of NASA projects

Testing and iterating, the secret sauce of Ara Kourchians and Steve Collins from the NASA Cobalt Project, developing a smart landing system from Mars. The system uses vision, LIDAR and IMU to reposition itself during the landing phase and provide precise landing capabilities. The system, developed by the Jet Propulsion Laboratory (NASA JPL) should be flying to Mars in 3 years.
