Mars appears red due to iron oxide, similar to rust and even human blood Probes reveal Mars is more tan or brown than red ...

Given that Mars is significantly colder and further from the Sun, it's easy to imagine that its polar ice caps have been there for ages, and the planet is frozen and static. But that isn't likely ...

If you've ever looked at Mars through a telescope, you probably noticed its two polar ice caps. The northern one is made largely of water ice—the most obvious sign that Mars was once a wetter ...

This image shows a cross-section of Mars's north polar cap, derived from data acquired by the Mars Reconnaissance Orbiter's Shallow Radar (SHARAD), one of six instruments on the spacecraft. The data ...

Originally taken on Sept. 1, 2008, and reshared this week, this image shows a dune field near the base of Mars' north polar ice cap, Planum Boreum.

What it is: Dunes on Mars Where it is: Around Planum Boreum, the north polar ice cap on Mars When it was shared: Aug 6, 2024 Why it's so special: This week, researchers at the University of ...

This stunning image of dune fields near Mars' north polar ice cap, taken by NASA's Mars Reconnaissance Orbiter, showcases the impact of polar winds on the Red Planet's landscape.
