A study suggests Mars takes its red hue from a type of mineral that forms in cool water, which could reveal insights about whether Mars was ever able to support life.

“We used an advanced grinder machine which reduced the size of our ferrihydrite and basalt to submicron sizes. The final size was 1/100th of a human hair and the reflected light spectra of these ...

"What we want to understand is the ancient Martian climate, the chemical processes on Mars -- not only ancient -- but also present," said Valantinas, who is working in the lab of Brown planetary ...

The water-rich iron mineral ferrihydrite may be the main culprit behind Mars's reddish dust, rather than the dry, rust-like mineral known as hematite.

“Mars is still the Red Planet,” said lead study author Adomas Valantinas, a postdoctoral fellow in the department of Earth, environmental and planetary ... a specialized grinder to create ...

FlackTektm, a leader in bladeless centrifugal materials processing, is excited to announce its strategic partnership with ATP Engineering, a renowned materials processing expert in the Netherlands.

The lab work involved replicating the size of Martian grains of dust (which are about 1/100th the width of a human hair) with an advanced grinder machine. They tested how light interacts with this ...

Now scientists think they have worked out exactly what gives our closest planetary neighbour its rusty ... they tried to recreate the dust by grinding particles to just one hundredth of the ...
