It is a scientific consensus that water once flowed on Mars, and that it had a denser atmosphere, meaning that it was once ...

The NASA Curiosity rover has detected the largest organic molecules found to date on Mars, opening a window into the red planet’s past. The newly detected compounds suggest complex organic chemistry ...

As fun as it would be to visit Mars, we wouldn't necessarily want to walk a mile in the Curiosity rover's shoes — or rather, its wheels. After landing in Mars' Gale Crater in 2012 and traveling some ...

For years, scientists have debated how long Mars could have supported life. While it’s been well-established that the planet ...

The Curiosity Mars rover photographed more rocks that are shaped like coral on the red planet's surface. Researchers said the rocks were evidence that at one point water was on Mars. The Curiosity ...

Years in the making, a major software update that has been installed on NASA’s Curiosity rover will enable the Mars robot to drive faster and reduce wear and tear on its wheels. Those are just two of ...

Mount Rainier summit drops 20 feet, climate study finds Ukrainian security source says Russia reacted to an attack by firing ...

NASA’s Curiosity rover was spotted making tracks on Mars’ surface in a new photo. Taken in February, the rover is seen as a tiny black speck as it makes its way to its next destination. The rover has ...

Images of knobbly rocks and rounded hills are delighting scientists as NASA’s Curiosity rover climbs Mount Sharp, a 5-mile-tall (8-kilometer-tall) mountain within the 96-mile-wide (154-kilometer-wide) ...

Scientists suspect iron meteorites might be able to resist erosion on Mars, which may explain why some appear perched on flat ground rather than embedded in craters. In other cases, a crater may have ...

Researchers at NYU Abu Dhabi have uncovered evidence that water once flowed beneath Martian sand dunes — suggesting that the Red Planet may have once had conditions capable of supporting life. Scienti ...
