NASA's Curiosity adds reverse driving for wheel protection on Mars

Terrain that NASA's Curiosity Mars rover is now crossing is as smooth as team members had anticipated based on earlier images from orbit. On Tuesday, Feb. 18, the rover covered 329 feet (100.3 meters), the mission's first long trek that used reverse driving and its farthest one-day advance of any kind in more than three months.

NASA's Curiosity Mars Rover checks for smoother route

The team operating NASA's Mars rover Curiosity is considering a path across a small sand dune to reach a favorable route to science destinations. A favorable route would skirt some terrain with sharp rocks considered more likely to poke holes in the rover's aluminum wheels.

Laser instrument on NASA Mars Rover tops 100,000 zaps

NASA's Curiosity Mars rover has passed the milestone of 100,000 shots fired by its laser. It uses the laser as one way to check which chemical elements are in rocks and soils.

Curiosity resumes science ops after analysis of voltage issue

NASA's Mars rover Curiosity resumed full science operations on Saturday, Nov. 23. Activities over the weekend included use of Curiosity’s robotic arm to deliver portions of powdered rock to a laboratory inside the rover. The powder has been stored in the arm since the rover collected it by drilling into the target rock "Cumberland" six months ago. Several portions of the powder have already been analyzed. The laboratory has flexibility for examining duplicate samples in different ways.

Mars rover team working to diagnose electrical issue

Science observations by NASA's Mars rover Curiosity have been suspended for a few days while engineers run tests to check possible causes of a voltage change detected on Nov. 17.

Curiosity Rover performs warm reset on Mars

NASA's Mars rover Curiosity experienced an unexpected software reboot (also known as a warm reset) yesterday (11/7/13) during a communications pass as it was sending engineering and science data to the Mars Reconnaissance Orbiter, for later downlinking to Earth.

NASA's Curiosity Mars Rover approaches 'Cooperstown'

NASA's Mars rover Curiosity completed its first two-day autonomous drive Monday, bringing the mobile laboratory to a good vantage point for pictures useful in selecting the next target the rover will reach out and touch.

Curiosity confirms origins of Martian meteorite

Earth’s most eminent emissary to Mars has just proven that those rare Martian visitors that sometimes drop in on Earth — a.k.a. Martian meteorites — really are from the Red Planet. A key new measurement of Mars’ atmosphere by NASA’s Curiosity rover provides the most definitive evidence yet of the origins of Mars meteorites while at the same time providing a way to rule out Martian origins of other meteorites.

Analyzing the diverse landing area of Curiosity on Mars

NASA's Curiosity rover is revealing a great deal about Mars, from long-ago processes in its interior to the current interaction between the Martian surface and atmosphere.

Curiosity's SAM instrument finds water and more in surface sample

The first scoop of soil analyzed by the analytical suite in the belly of NASA's Curiosity rover reveals that fine materials on the surface of the planet contain several percent water by weight. The results were published today in Science as one article in a five-paper special section on the Curiosity mission.

NASA's Curiosity Mars rover passes one kilometer mark

The latest drive by NASA's Curiosity Mars rover brought the total distance that the rover has driven on Mars to more than 1 kilometer. One kilometer is about 0.62 miles.

A billion-pixel view from Mars

A billion-pixel view from the surface of Mars, from NASA's Mars rover Curiosity, offers armchair explorers a way to examine one part of the Red Planet in great detail.

NASA's Curiosity Mars Rover approaches turning point

NASA's Mars Science Laboratory mission is approaching its biggest turning point since landing its rover, Curiosity, inside Mars' Gale Crater last summer.

NASA's Mars rover Curiosity drills second rock target

NASA's Mars rover Curiosity has used the drill on its robotic arm to collect a powdered sample from the interior of a rock called "Cumberland."

NASA: Limited Martian atmosphere is still dynamic

Mars may have lost much of its original atmosphere, but what's left remains quite active, recent findings from NASA's Mars rover Curiosity indicate.

Curiosity rover suffers major malfunction

The Curiosity ground team has been forced to switch the Mars rover to a redundant onboard computer, thanks to a memory problem.

Curiosity collects first Martian rock sample

NASA's Curiosity rover has successfully extracted a sample from a Martian rock - the first ever to be collected from a planet beyond Earth.

Curiosity drills into Martian rock

NASA's Curiosity rover has, for the first time, used the drill on its robotic arm to bore into a rock on Mars and extract a sample for analysis.

Curiosity set to drill its first rock

NASA's Mars rover Curiosity is on the road again, driving toward a flat rock with pale veins that the team says could help shed light on Mars' watery past.

Curiosity sweeps rock clean for test

Another crucial instrument on the Curiosity Mars rover has had its  first test: the Dust Removal Tool, used to sweep dust from the rover's target rocks.
