A big mystery is why the ridges were hardened into these big patterns and why only here,” said Ashwin Vasavada, project scientist for the NASA Curiosity rover, following the mission publishing the ...

Curiosity finds strange boxwork ridges on Mars that hint at ancient underground water. Scientists are now drilling for ...

The Mars rover found geological formations in Gale Crater showing how water percolated beneath the surface, and ...

Scientists had hypothesized before the rover arrived that the peculiar ridges formed with the last trickles of water in the ...

New images from NASA's Curiosity Mars rover show the first close-up views of a region scientists had previously observed only ...

Mars was once wet, with rivers and lakes and even an ocean that existed on the Red Planet between about 4.1 and 3.7 billion ...

“Sulphate minerals exist with different amounts of water in most regions on Mars and allow us to understand how water moved around the planet, which is key to understanding its past habitability ...

"Our findings provide a methodological framework for detecting biosignatures in Martian sulfate minerals, potentially guiding future Mars exploration missions," said Sellam.

A hidden box-lattice suggests groundwater sculpted Mars long after surface water fled; Curiosity’s drills aim to confirm the tale.

A NASA rover taking rock samples on Mars has uncovered a plentiful mineral that was invisible to orbiters studying the Red Planet from space.. Scientists say the discovery of siderite, a type of ...

But only evaporation would lead to highly pure siderite forming in the same geologic layer as the sulfate minerals the team identified, gypsum and starkeyite. Atmospheric CO 2 must have dissolved ...

Policies have focused on supply of minerals for EV batteries. We need to think about demand, too, Gregory Wischer and Morgan Bazilian write in a guest commentary.
