NASA wants a rocket-powered UAV to fly around the Red Planet, photographing the surface. The plane, repetitively named ARES (not to be confused with NASA’s shuttle replacement, also named ARES), would fly to Mars in a regular rocket. Once it reaches the fourth rock from the Sun, it would pop out of the capsule, deploy its wings, and fire the rockets for an hour-long flight through the Martian sky. During that flight, ARES would cover about 373 miles, which is a little less than 100 times the area covered by the Spirit rover over the last five years.
