NASA rover sets distance record
Quote:
On Sunday, the robot rover advanced another 157 feet (48 meters) as it continued along the rim of a Martian crater, putting Opportunity's total odometer at 25.01 miles (40.25 km), according to NASA's Jet Propulsion Laboratory near Pasadena, California. By comparison, the Soviet Union's Lunokhod 2 rover drove about 24.2 miles (39 km) in less than five months after landing on Earth's moon on Jan. 15, 1973, JPL said. The manned lunar rover driven by astronauts of the Apollo 17 mission logged 22.2 miles (35.7 km) in 1972. "Opportunity has driven farther than any other wheeled vehicle on another world," JPL's Mars Exploration Rover Project Manager John Callas said in a statement. Opportunity still has miles to go. Scientists said they plan next to direct the rover to a nearby Martian valley that would extend its accumulated operating distance to 26.2 miles, the traditional length of a marathon. |
