Mars rovers

NASA's Perseverance Mars rover just snapped a new photo of a Red Planet rock that looks a lot like an avocado.

The Perseverance rover's MOXIE experiment produced a total of 122 grams of oxygen on Mars. At its most efficient, it generated 12 grams of the life-sustaining element every hour.

NASA's Ingenuity Mars helicopter flew for the 57th time on Sept. 3, a sortie that pushed the robot's total Red Planet air time over 100 minutes.

Is something fishy happening on the Red Planet, or is it all in our minds again?

NASA's Ingenuity Mars helicopter flew for the 56th time last week, staying aloft for nearly 2.5 minutes on a sortie that covered 1,344 feet (410 meters) of ground.

NASA's Perseverance Mars rover has captured photos of a big sunspot, which should rotate into view for those of us on Earth in the coming days.

NASA's Ingenuity Mars helicopter has taken to the skies yet again, covering 866 feet (264 meters) of ground on its 55th Red Planet flight.

The Curiosity Mars rover recently aced its toughest Red Planet climb yet: a sharp 23-degree slope covered slippery sand and wheel-size rocks.

NASA has test-fired rocket motors as part of the development of an ascent vehicle designed to launch samples off the surface of Mars.

Ancient mud cracks found by NASA's Curiosity rover suggest that Mars underwent a repeated cycle of wet and dry spells that could have supported the emergence of life.
