Washington - The US space agency's Opportunity rover has now clocked more miles on Mars than any man-made vehicle to reach another celestial body, Nasa said on Monday.

Since arriving on the Red Planet in 2004, the solar-powered robot has journeyed across 40km of Martian terrain.

That surpasses the previous record held by the Soviet Union's Lunokhod 2 rover, which landed on the moon in 1973.

"Opportunity has driven farther than any other wheeled vehicle on another world," said Mars Exploration Rover Project Manager John Callas of Nasa's Jet Propulsion Laboratory in Pasadena, California.

"This is so remarkable considering Opportunity was intended to drive about one kilometre and was never designed for distance."

Opportunity and its twin rover, Spirit - now defunct - discovered wet environmental conditions on ancient Mars, some of which are mild enough to have been favourable for life.

Opportunity is now exploring the Endeavour Crater on Mars.

'Curiosity' unlikely to break record

Its next-generation robotic counterpart, the Curiosity rover, launched in 2012 and is tooling around near the Gale Crater on Mars.

But despite its bigger size and more advanced suite of scientific tools, NASA spokesman Guy Webster said the $2.5bn Curiosity vehicle is not likely to break Opportunity's record.

"Curiosity has driven about 8.6km so far," Webster told AFP in an e-mail.

"The main science destinations for Curiosity, on lower Mount Sharp, are much closer than the 32km it would take to surpass Opportunity's current total," he added.

"Also, as Curiosity's mileage increases, who knows how much longer and farther Opportunity will keep driving?"

Nasa said that the Soviet Union's Lunokhod 2 rover landed on Earth's moon on 15 January, 1973, and drove about 39km in less than five months.

Those figures are based on calculations recently made using images from NASA's Lunar Reconnaissance Orbiter (LRO) cameras that reveal Lunokhod 2's tracks, the US space agency said.
