The Mars water debate continues. A team of scientists suggests vast oceans of water may not be locked within the Red Planet's ...

Researchers examining seismic data recorded on Mars say the have found evidence supporting the presence of liquid water deep ...

Mars might hold enough subsurface water to cover its surface in a global ocean between 0.62 to 1.24 miles (1 to 2 kilometers) ...

Research published late last year indicated “seismic discontinuities in the Martian crust” that scientists believe could be an indicator of liquid water under the Martian surface, raising the ...

Are subterranean lifeforms viable on Mars? A new interpretation of Martian seismic data by scientists Ikuo Katayama of ...

Electrolysis has been a mainstay of crewed mission designs for the outer solar system for decades. It is the most commonly ...

Water once existed in abundance of at the surface of Mars. How much of that water has been stored in the planet's crust is still unclear, according to a new analysis.

Mars may once have held enough water to fill oceans and form coastlines. The planet’s red dust contains water and likely formed in cold conditions.

The ferrihydrite might have formed back when there was still water on the planet–potentially when it was habitable. In the decades that astronomers have been studying Mars, we’ve learned that ...

Researchers are looking underfoot to uncover the mysterious past of Mars: Martian regoliths in the soil. Their water storage capabilities may help us understand the change in water on Mars over time.

A new study claims that a mineral found in Mars' dust called ferrihydrite, which forms in the presence of cool water, is likely what gives the planet its reddish hue.
