Curiosity rover: Having spent 687 days on the Red Planet, NASA's Curiosity rover has completed one lap around the sun on Mars.
NASA's Curiosity rover is eyeing a three-foot-tall sand dune, an ambitious climb for the SUV-sized rover. Despite the size of the climb, NASA doesn't expect the rover to actually catch air on this maneuver.
At the European Planetary Science Congress, researchers summed up the flood of evidence that Mars was once a wet planet.
Curiosity performed its longest one-day drive last week, traversing 464 feet across the Martian surface.
