NASA ARES: Aerial Regional-scale Environmental Survey Aircraft proposed for 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.

The ARES team sought to be selected and funded as a NASA Mars Scout Mission for a 2011 or 2013 launch window. However, the MAVEN mission was chosen instead.




ARES would have travelled 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.

Propulsion
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. The aircraft was intended to fly for about one hour.
