They’re Off and Running for NASA Rover Mars Marathon NASA

About 90 employees at NASA’s Jet Propulsion Laboratory, Pasadena, California, are running 1.2 mile laps through the laboratory grounds today as part of a marathon-length relay to celebrate the first-ever Martian marathon.
NASA’s Mars Exploration Rover Opportunity, which landed on Mars in 2004, surpassed a marathon length of Martian driving on March 24.

Opportunity’s original three-month prime mission in 2004 yielded evidence of environments with liquid water soaking the ground and flowing on planet’s surface. As the rover continued to operate far beyond expectations for its lifespan, scientists chose the rim of Endeavour Crater as a long-term destination. Since 2011, examinations of Endeavour’s rim have provided information about ancient wet conditions less acidic, and more favorable for microbial life, than the environment that left clues found earlier in the mission.
