Abstract: A safe landing point search device for searching for a safe landing point of an unmanned exploration device that lands on and explores a celestial body, includes a terrain map obtaining unit configured to obtain a terrain map, a contour line generating unit configured to generate contour lines based on a reference minimum height value and a height interval value by using the terrain map, a largest empty circle (LEC) searching unit configured to search for one or more LECs having a radius greater than or equal to a lower-limit radius in a contour line map including the contour lines, and a safe landing point outputting unit configured to output a safe landing point having a largest radius among the one or more LECs and transmit the safe landing point to the unmanned exploration device.
