NASA’s Opportunity Rover Just Set the Off-World Driving Distance Record

NASA’s Opportunity rover landed on the surface of Mars in January of 2004. As of Sunday (July 26), the Opportunity rover had driven a total distance of 25 miles (40 kilometers).

Opportunity took the top spot in total off-world distance traveled by surpassing Russia’s Lunokhod 2 lunar rover, which traveled a total distance of 39 kilometers across the surface of the moon between January and May of 1973.

The Russian rover helped to bring about a golden age of space exploration in the 70s. As a sign of respect, the Opportunity rover’s operators decided to commemorate the Russian rover by naming one of the first craters they encountered after it.

The craziest part of this record is that the Opportunity rover was only expected to travel a short distance when it was first sent to Mars in 2004. Here’s John Callas, who manages the Mars Exploration Project at NASA’s Jet-Propulsion Laboratory (JPL) in California:

“This is so remarkable considering Opportunity was intended to drive about one kilometer and was never designed for distance. But what is really important is not how many miles the rover has racked up, but how much exploration and discovery we have accomplished over that distance.”

The Opportunity rover is collecting data on Mars as part of a long-term plan for a manned mission to the planet around the year 2030.
