NASA Rover Samples Active Linear Dune on Mars

From early February to early April, the rover examined four sites near a linear dune for comparison with what it found in late 2015 and early 2016 during its investigation of crescent-shaped dunes. This two-phase campaign is the first close-up study of active dunes anywhere other than Earth.
Among the questions this Martian dune campaign is addressing is how winds shape dunes that are relatively close together, on the same side of the same mountain, into different patterns. Others include whether Martian winds sort grains of sand in ways that affect the distribution of mineral compositions, which would have implications for studies of Martian sandstones.

Breaks Observed in Rover Wheel Treads

A routine check of the aluminium wheels on NASA's Curiosity Mars rover has found two small breaks on the rover's left middle wheel-the latest sign of wear and tear as the rover continues its journey, now approaching the 16 kilometer mark.
The mission's first and second breaks in raised treads, called grousers, appeared in a March 19 image check of the wheels, documenting that these breaks occurred after the last check, on Jan. 27.

Upgrade Helps NASA Study Mineral Veins on Mars

Scientists now have a better understanding about a site with the most chemically diverse mineral veins NASA's Curiosity rover has examined on Mars, thanks in part to a valuable new resource scientists used in analysing data from the rover.

Curiosity Mars rover takes low-angle 'selfie'

The US space agency has issued another of the "selfie" portraits acquired by the Curiosity rover on Mars.
Nasa tries to make one of these mosaics at every location where the robot drills into the surface.
This latest picture was taken by the rover at "Buckskin" - the seventh rock target on the mission to provide a sample for analysis.

Curiosity Rover Finds Biologically Useful Nitrogen on Mars

A team using the Sample Analysis at Mars (SAM) instrument suite aboard NASA's Curiosity rover has made the first detection of nitrogen on the surface of Mars from release during heating of Martian sediments.
The nitrogen was detected in the form of nitric oxide, and could be released from the breakdown of nitrates during heating.

Curiosity Mars rover back in the groove

After some downtime to enable a software upgrade, the Curiosity rover on Mars has got straight back to work by drilling into a rock.
The robot sunk the latest shallow mini-test hole in a target called Mojave2.

Curiosity Mars Rover Finds Mineral Match

Reddish rock powder from the first hole drilled into a Martian mountain by NASA's Curiosity rover has yielded the mission's first confirmation of a mineral mapped from orbit.
Curiosity collected the powder by drilling into a rock outcrop at the base of Mount Sharp in late September. The robotic arm delivered a pinch of the sample to the Chemistry and Mineralogy (CheMin) instrument inside the rover. This sample, from a target called "Confidence Hills" within the "Pahrump Hills" outcrop, contained much more hematite than any rock or soil sample previously analysed by CheMin during the two-year-old mission. Hematite is an iron-oxide mineral that gives clues about ancient environmental conditions from when it formed.
