![]() For instance, the aircraft will need sufficient lift to sustain its total weight, together with that of attendant scientific equipment, and will require a high lift-to-drag performance for wide-range observation. However, Martian atmospheric flight has several complex technical features that need to be considered in the aerodynamic design of the Mars airplane. NASA also studied a Mars airplane, called Aerial Regional-scale Environmental Survey (ARES), in the early 2000s. Ī Mars airplane would fly and explore the low-density Martian atmosphere at several kilometers altitude with a few hundred kilometers of cruising range and would constitute a new observation platform for future Mars exploration. One option in the Japanese Mars exploration effort is a fixed, main-wing Mars airplane that has been contemplated and studied. In Japan, the next Mars exploration mission, called Mars Exploration with Lander-Orbiter Synergy (MELOS), has been suggested by a Japanese research group that is sponsored by the Japan Aerospace Exploration Agency (JAXA), which marks the initiation of Japanese Martian exploratory research efforts.
