Modern aircrafts such as drones have been used in aerial surveying since 1935. Unlike the Earth, Mars has a very thin atmosphere and thus poses many constraints, such as requiring a large wing area to compensate for the low density of the Martian atmosphere. A small-scale, reconnaissance glider comes with high maneuverability and presents the potential for taking high-resolution images and data in dangerous locations such as canyons, ridges or valleys of less than a couple of kilometers in diameter. Furthermore, these small-scale gliders can also sense the concentration of methane gas in these locations which is crucial in determining their possibilities of becoming a future Martian base. These small-scale gliders have a total wing area of 0.1 m2, an operation time of at least 613.5 seconds, and are designed to be deployed from the NASA ARES Mars Airplane at 2.41 km. All in all, these gliders are cost-effective and their applications extend to numerous studies.
