Mars Rover

Curiosity photographed an odd, flat object that mission team members initially thought might have fallen off the car-size robot. But the "debris" turned out to be a Red Planet rock.

NASA's Mars rover Curiosity has found intriguing structures on Mars that look like tiny, fossilized worm burrows — but mission team members aren't claiming that the finds are evidence of life.

NASA's sharp-eyed Mars Reconnaissance Orbiter (MRO) has now circled the Red Planet 50,000 times.

NASA's Mars rover Curiosity has stumbled onto another rock that likely fell from space.

NASA's Mars rover Curiosity has taken a gorgeous selfie that shows the rugged, mountainous landscape the six-wheeled robot will be exploring during its newly begun extended mission.

The car-size Curiosity rover was hard at work investigating Namib Dune — part of a larger complex of shifting dark Martian sand called Bagnold Dunes — when it captured the photo on Jan. 19.

Curiosity captured the images, which mission team members combined into a Martian sunset video, with its Mast Camera between dust storms on April 15, NASA officials said.
