Aerial Regional-scale Environmental Survey

ARES aircraft
Mission type Mars atmospheric probe
Operator NASA
Mission duration 1 hour at Mars

The Aerial Regional-scale Environmental Survey (ARES) was a proposal by NASA's Langley Research Center to build a powered aircraft that would fly on Mars.[1][2][3] The ARES team sought to be selected and funded as a NASA Mars Scout Mission for a 2011[4] or 2013 launch window. However, the MAVEN mission was chosen instead.[5]

ARES would have traveled to Mars compactly folded into a protective aeroshell; upon entry in the thin atmosphere, the capsule would have deployed a parachute to decelerate, followed by ARES release at altitude.

Among other things, the aircraft would have investigated the atmosphere and weak magnetic field.[6]


Propulsion remained undetermined. The two main criteria used to evaluate the propulsion system were flight range and implementation risk. Possible propulsion technologies were electrical motors, internal combustion and rocket systems.[4] The aircraft was intended to fly for about one hour.
