How did the moons of Mars, Phobos and Deimos, form and evolve orbiting the Red Planet? This is what a recent study published in Icarus hopes to address as a team of researchers investigated the ...

The observation of small gullies on Mars was one of the more unexpected discoveries of the Mars Observer Camera (MOC) aboard the Mars Global Surveyor spacecraft. The characteristics of these gullies ...

A recent discovery on the surface of Mars has generated significant curiosity among space enthusiasts and experts alike. A perfectly square-shaped structure, approximately 3 kilometers (1.8 miles) ...

A new investigative technique has shown the latitudinal distribution of ice-rich landforms on Mars. This large-scale study enables future, more detailed investigations to study several young deposits ...

What can sand dunes on Earth and Mars teach us about the latter’s wind behavior and atmosphere? This is what a recently awarded NASA grant hopes to address as a PhD student at Texas A&M University ...

Due to extreme temperatures and the dryness of Mars, it’s thought to be impossible for liquid water to form on the planet’s surface, a critical precondition for habitability. The only hope of finding ...

Each spring, when the winter frost departs, the bulbous bodies and sprawling legs of “spiders” appear across Mars’ southern hemisphere. They’re known as araneiform terrain, and scientists at NASA’s ...

New images from NASA's Curiosity Mars rover show the first close-up views of a region scientists had previously observed only from orbit. The images and data being collected are already raising new ...
