When a Mars rover accidentally crushed a small rock and exposed a flash of vivid yellow inside, it turned a routine drive into one of the most intriguing discoveries of the mission. The fractured fragment,

More than five years into its mission, NASA's Mars Perseverance rover is still ambling across the surface of the red planet, doing what any five-year-old loves to do – stopping to look at every rock on its path.

Agency says it may have found signs of life on the Red Planet Mars during a press conference about comet 3I/ATLAS

Interest in Martian life had been spurred by a now infamous announcement from the White House lawn in 1996, when President Bill Clinton declared that signs of life had been detected in a Martian meteorite found in Antarctica. That claim was later refuted—but it caused enough clamor to put the search for Martian life at the top of NASA’s agenda.

Researcher Valentin Bickel wanted to know just how intense winds can be on the red planet. Using data obtained by the Mars camera CaSSIS (Color and Stereo Surface Imaging System), the ExoMars Trace Gas Orbiter,

New images from the Mars Express orbiter reveal evidence of a past ice age at Mars's mid-latitudes and shine light on the planet's dynamic climate history.

(CNN) — Data from a retired NASA mission has revealed evidence of an underground reservoir of water deep beneath the surface of Mars, according to new research. A team of scientists estimates that there may be enough water, trapped in tiny cracks and pores of rock in the middle of the Martian crust, to fill oceans on the planet’s surface. The groundwater would likely cover the entirety of ...

Mars is a cold, dry, desert-like planet. But billions of years ago, scientific evidence suggests that it had a thick atmosphere, which kept it warm enough to support flowing water on its surface. So, what happened to the Red Planet, and could it happen to Earth?
