NASA's Opportunity Mars Rover completes 42 km marathon milestone in 11 yrs

NASA's Opportunity Mars Rover has recently completed the first 42.195 kilometers marathon milestone on Mars in 11 years and two months, after its January 2004 landing in Eagle Crater.

The vehicle surpassed marathon distance of 26.219 miles (42.195 kilometers) with a drive completed on March 24, 2015, during the 3,968th Martian day, or sol, of Opportunity's work on Mars.

John Callas, Opportunity project manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, said that this was the first time any human enterprise has exceeded the distance of a marathon on the surface of another world and it happens only once.
