Scientists resume use of Curiosity rover’s drill and internal lab instruments
NASA’s Curiosity rover successfully drilled a 2-inch-deep hole in a target called “Duluth” on May 20. It was the first rock sample captured by the drill since October 2016.

Internal debris may be causing problem with Mars rover’s drill
File photo of Curiosity’s drill bit from Feb. 24, 2015. Credit: NASA/JPL-Caltech/MSSS Engineers suspect a piece of foreign object debris may be intermittently stalling a motor needed to place the Curiosity Mars rover’s drill bit onto rocks, and the robot’s ground team is assessing the source of the potential contamination. More importantly, Curiosity project manager…

Oxygen finding strengthens case that Mars was once habitable
This scene shows NASA’s Curiosity Mars rover at a location called “Windjana,” where the rover found rocks containing manganese-oxide minerals, which require abundant water and strongly oxidizing conditions to form. Credit: NASA/JPL-Caltech/MSSS High concentrations of manganese oxides found in Martian rocks by NASA’s Curiosity rover indicate the red planet’s atmosphere once had much more oxygen…

Rover data suggest Mars crater once contained long-lived lake
This illustration depicts a lake of water partially filling Mars’ Gale Crater, receiving runoff from snow melting on the crater’s northern rim. Credit: NASA/JPL-Caltech/ESA/DLR/FU Berlin/MSSS Scientists analyzing imagery from NASA’s Curiosity Mars rover believe sediments left by an ancient lake more than three billion years ago formed a towering mountain that is set to be…
