ABSTRACT
This article reports that a Mars Rover could hop around the planet's surface harvesting atmospheric gas for propulsion has been awarded funding by the U.S. National Aeronautics and Space Administration. The Mars Gas Hopper, designed by Robert Zubrin of Pioneer Astronautics, will use an electric pump to capture fuel in the form carbon dioxide from the Martian atmosphere. Rather than taking months to move a few kilometers like current rover designs, the gas hopper would be able to fly distances of up to 100 km from site to site to carry out research. A demonstration version of the technology has shown that the unit can fly 100 m and descend under control. Zurbin said that the gas hopper will totally outclass a surface rover. The Martian atmosphere is 95 per cent carbon dioxide so refueling will be easy.
