The Mars Institute's MARS-1 Humvee rover for the NASA Haughton-Mars Project (HMP). The doors of the 8,800-lb (4 metric ton) vehicle were taken off for the 23-mile (37-kilometers) sea ice crossing between Cornwallis Island and Devon Island, High Arctic, to facilitate crewmember evacuation in the event of an emergency.
