Curiosity Mars Rover

The Curiosity rover might be spotting signs of the Martian climate drying up in ancient times.

A long-running NASA rover imaged twisted Red Planet rock pillars.

The strange door-like feature discovered in a martian cliff earlier this month is perfectly natural but provides a "doorway into the past", said NASA.

NASA's Curiosity Mars rover unexpectedly changed its course up Mount Sharp to avoid hazardous "gator-back" terrain.

A new image taken by the Curiosity rover reveals a tiny, flower-like mineral deposit less than half an inch wide on the Martian surface.

The clouds were so faint that NASA employed special imaging techniques to spot them.

NASA's Curiosity rover has left plenty of marks on Mars over the past nine-plus years, and the Red Planet is returning the favor.

NASA's Curiosity rover has found some interesting organic compounds that may be signs of ancient Mars life, but much more work is needed to vet that hypothesis.

NASA's Curiosity rover snapped a stunning new selfie surrounded by expansive, rocky terrain on Mars.

NASA plans to pause most of its Martian work in October for safety reasons associated with the Red Planet's position in space.

NASA's Mars rover Curiosity has rolled into a patch of ground that could shed considerable light on the Red Planet's climate history.

Mars' Gale Crater may not have been so wet after all, a new study suggests.

Since touching down on Aug. 5, 2012, Curiosity has been helping scientists better understand Mars' past habitability and how the planet has changed over time.

Scientists now seem to understand why the gas has been detected at ground level on Mars but not higher up in the air.

It might look like a postcard from Arizona, but this snapshot shows something much more exotic: the planet Mars, as seen by NASA's Curiosity rover.

NASA's Mars Reconnaissance Orbiter captured a dramatic image last month of Curiosity ascending Mont Mercou, a landform on the slopes of the Red Planet's 3.4-mile-high (5.5 kilometers) Mt. Sharp.

Mars did not dry up all at once, but fluctuated between dry spells and wetter times, a new study finds.

NASA's Mars rover Curiosity posed for a selfie in front of a beautiful Martian rock outcrop called "Mont Mercou" after probing the area for clues about the Red Planet's past.

NASA's Curiosity rover marked 3,000 Martian days, or "sols," on the Red Planet Tuesday (Jan. 12), a mere five weeks before NASA's Perseverance rover is scheduled to touch down.
