Researchers discovered Mars subtly affects Earth’s orbit and axial tilt. These small changes help trigger ice ages and ...

Helicopters on Mars may sound like something from a science fiction novel — or perhaps just a typical "Doctor Who" episode. But actually, they're not fully confined to the world of sci-fi; after all, ...

Most planetary scientists agree that Mars’ extreme conditions would be uninhabitable to life as we know it. New research, however, suggests that we might be underestimating the hardiness of lichens.

As humanity edges closer to sending astronauts to Mars, scientists are drawing attention to an often-overlooked threat: Martian dust. A recent study suggests that this dust could pose significant ...

A new study by planetary scientists at Brown University and the University of Bern in Switzerland casts doubt on one of the most tantalizing clues that water might be flowing on present-day Mars. For ...

Time moves differently on Mars — not in the Tibetan philosophy sense of the word, but in a measurable, physics-will-ruin-your-mission kind of way that's giving NASA engineers a real headache. As the ...

Sapphire Canyon has features that were immediately exciting to NASA scientists. Will they ever get to study it up close? Credit: NASA/JPL A new study using a novel form of spectroscopy is helping to ...

Using images from cameras on Mars orbiters, an international research team has discovered structures on Mars that are very ...

The research has implications for NASA’s goals to build a base on the moon and eventually conduct crewed missions to Mars.

Mars had an Arctic-sized ocean, and scientists are only now beginning to see the outline of it. For a long time, the planet ...
