They then compared their creations to dust from Mars’ surface. The findings change our understanding of Mars and its history. Ferrihydrite lending to Mars' red coloring could mean that there was ...

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 ...

and evidence of ancient water flows on the Red Planet’s surface. The newly released images provide a detailed and immersive perspective of Mars, giving scientists and space enthusiasts a chance ...

While the spacecraft was decommissioned in 2006, the vast amount of data it collected continues to be analyzed, occasionally revealing intriguing new details about Mars’ surface. The square ...

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 ...

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 ...

When a mudflat crumbles on Earth, or an ice sheet splinters on one of Jupiter's moons (Europa), or an ancient lakebed breaks on Mars ... footage of a planetary surface changing over millennia ...

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 ...

Professor Roger Wiens of Indiana's Purdue University said his team found over 4,000 small white pebbles and large rocks from Mars' surface. He told Newsweek: "We have known for a long time that ...

Some models predict that any liquid water on Mars' surface must have been covered by sheets of ice before it disappeared. However, the new findings, which were published Jan. 15 in the journal ...

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.
