If that was the case, the hematite would have formed later in Mars’ history, after it was suspected of hosting lakes and rivers on its surface. New research combining data from multiple missions ...

The rover operated from May 2021 to May 2022 Its radar transmitted high-frequency radio waves The rover probed up to 80 meters (260 feet) beneath the surface China's Zhurong rover, which created ...

Scientists reckon the red hue of Mars might have originated in an earlier period in the planet's past when liquid water was widespread on the surface. The research, published in Nature Communications, ...

Mars may have once had an ocean with sandy beaches, researchers say. NASA missions over the years have found evidence that water once flowed on the Martian surface billions of years ago.

But a team of ESA and NASA scientists now think that Mars rusted earlier in its ancient past than previously known, when liquid water was widespread on the planet’s surface. Iron oxide—which ...

Ferrihydrite typically forms quickly in the presence of cool water, and so must have formed when Mars still had water on its surface. The ferrihydrite has kept its watery signature to the present ...

Once Mars dried out, this rusty rock was broken down into dust over billions of years. Strong winds blew this dust all over the planet’s surface, gradually turning Mars red. Signatures of the ...

Until now, its role in Mars' surface composition was not well understood, but this new research suggests that it could be an important part of the dust that blankets the planet’s surface.

On Earth, it is commonly associated with processes like the weathering of volcanic rocks and ash. Until now, its role in Mars' surface composition was not well understood, but the new study suggests ...

Present-day Mars is a barren and inhospitable planet, but it may have once had sandy beaches and tranquil ocean vistas. According to findings published on February 24 in the Proceedings of the ...

Chinese Zhurong rover discovered underwater layers of sediment beneath the Martian surface that closely resemble Earth’s coastal beach deposits, providing the strongest evidence yet for an ancient ...
