The first marathon on Mars was finally completed Tuesday by NASA’s Opportunity Mars Rover—and it only took about 11 years and two months.
“This is the first time any human enterprise has exceeded the distance of a marathon on the surface of another world,” John Callas, the rover’s project manager at NASA’s Jet Propulsion Laboratory, said in a celebratory statement. “A first time happens only once.”
Opportunity landed on the Red Planet on Jan. 25, 2004, with an “original three-month prime mission” but since then been driving around and stopping to perform scientific research. As of Tuesday, Opportunity is on the west rim of Endeavor Crater—nicknamed “Marathon Valley”—where it continues to research the planet’s ancient wet conditions.

Rover tracks disappear toward the horizon like the wake of a ship across the desolate sea of sand between the craters Endurance and Victoria on the Meridiani Plains. NASA— JPL-Caltech / Cornell UniversityThe Mars Rover Spirit took this sublime view of a sunset over the rim of Gusev Crater, about 80 kilometers (50 miles) away. NASA—JPL-Caltech / Texas A&M / CornellA false-color image of Endurance Crater. In this image, tendrils of sand less than 3.3 ft (1 m) high extend from the main dune field toward the rover. Dunes are a common feature across the surface of Mars. Before the rover headed down to the dunes, mission managers first established whether the slippery slope that led to them was firm enough to ensure a successful drive back out of the crater. Otherwise, the dune field would become a sand trap.

Nicknamed "blueberries" by mission scientists, the little pellets are actually hematites, an iron oxide typically formed in standing water—of which Mars once had plenty.NASA—JPL-Caltech / Cornell / USGS / Cathy WeitzSpirit obtained this view of the area called Home Plate while parked atop a formation called Husband Hill.

The view is presented in false color to make differences in surface materials more visible. A portion of Endeavour Crater's eastern rim, nearly 19 miles (30 km) distant, is visible.NASA—JPL-Caltech / CornellNASA's Spirit rover acquired this false-color image after using its abrasion tool to brush the surfaces of rock targets informally named "Stars" (left) and "Crawfords" (right). Small streaks of dust extend for several centimeters behind the chips and pebbles in the dusty soil.

Opportunity previously broke a record last year when it overtook the former Soviet Union’s Lunokhod 2 moon rover as the off-Earth rover that had traveled the most distance.
“This mission isn’t about setting distance records, of course; it’s about making scientific discoveries on Mars and inspiring future explorers to achieve even more,” said Steve Squyres, the rover’s principal investigator at Cornell University. “Still, running a marathon on Mars feels pretty cool.”
Opportunity and NASA’s Curiosity Mars Rover are the only operating rovers on Mars. NASA’s previous rover, Spirit Mars Rover, became stuck in soft soil in 2009 and ceased communication with scientists in 2010.

A full-circle view released by NASA on June 20, 2013, combined nearly 900 images taken by NASA's Curiosity Mars rover, generating a panorama with 1.3 billion pixels in the full-resolution version. The view is centered toward the south, with north at both ends. It shows NASA's Mars rover Curiosity at the 'Rocknest' site where the rover scooped up samples of windblown dust and sand.NASA/JPL-Caltech/MSSS/EPANASA's Mars Curiosity Rover captures a selfie to mark a full Martian year -- 687 Earth days -- spent exploring the Red Planet.NASA/JPLA detailed telephoto view from Curiosity shows Mount Sharp.

These engineering cameras are located at the rover's base, and are lower-resolution than the color images produced by the rover's mast.

The rover is equipped with a nuclear-powered lab capable of vaporizing rocks and ingesting soil, measuring habitability, and whether Mars ever had an environment able to support life.University of Arizona/JPL-Caltech/NASA
