Mars Rover's Long Drive
If you think your driving is out of this world, you might want to give NASA a call. Its Opportunity Mars rover just squashed the Soviet Union’s record for off-Earth roving distance on Mars, driving 25 miles on the Red Planet. The rover has driven farther than any other wheeled vehicle on another world. NASA project manager John Callas says Opportunity Mars was only intended to drive about one kilometer, but on July 27, it had clocked 40.25 kilometers (25.01 miles). The Russian rover, which landed on the moon in 1973, drove about 24.2 miles in under five months.
