NASA's Mars rover Opportunity is conducting a "walkabout" survey of Marathon Valley, where the rover's operators plan to use it through the upcoming Martian winter to study outcrops that host clay minerals.

NASA's Mars rover Opportunity has completed its first Red Planet marathon, clocking 42.195 kilometres in a finish time of roughly 11 years and two months.

NASA's decade-old Mars rover Opportunity has set a new off-Earth, off-road distance record, logging just over 25 miles (40 km) on the surface of the Red Planet to surpass the benchmark set in 1973 by a Russian probe on the moon.
