Mars has a history of liquid water on its surface, including lakes like the one that used to occupy Jezero Crater, which have long since dried up. Ancient water that carried debris—and melted water ...

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 ...

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 ...

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 ...

High-resolution photos of lava flows on Mars reveal coiling spiral patterns that resemble snail or nautilus shells. Such patterns have been found in a few locations on Earth, but never before on Mars.

As the Mars rover Perseverance crested the top of Witch Hazel Hill, its operators back on Earth expected amazing things. This area on the western rim of the Jezero crater, along an ancient river delta ...

New experiments have shown that the core of Mars formed much faster than Earth's core, thanks to molten iron and nickel sulfides seeping down through solid rock and into the center of the Red Planet.
