In the near future major part population should be shifted to other planet, in order to survive from the population boom. Many scientists have been working on that project where payload should be released carefully. It depends on the hazards in the final descent on the landing surface. So the lunar lenders are designed to identify the safe landing location automatically. This is based on the two critical sensor technologies by NASA, where one of which is a three-dimensional active imaging device used to measure topography of the landing area and other to measure speed to land safely in the precise landing location.
