NASA’s ESCAPADE mission seeks to reveal why Mars lost its atmosphere and water, launching after years of delays and ...

The mystery of Mars' magnetic field has puzzled scientists for decades. A new study proposes a surprising explanation for its current asymmetry. Researchers at the University of Texas simulated a ...

AUSTIN, Texas — Mars played by different rules than Earth when forming its magnetic field. Rather than generating magnetism with a solid core surrounded by liquid—Earth’s approach—the Red Planet ...

Mars is a cold, dry, desert-like planet. But billions of years ago, scientific evidence suggests that it had a thick ...

Envision a time when hundreds of spacecraft are exploring the solar system and beyond. That’s the future that NASA’s ESCAPADE ...

First ever supercomputer simulations of Mars with a fully molten core could explain the Red Planet's unusual magnetic field. Billions of years ago, Mars had an active magnetic field. Mysteriously, its ...

Blue Origin's New Glenn rocket, carrying two NASA satellites designed to study space weather on Mars, is back on track for ...

A high-resolution map of Mars's entire magnetic field provides new evidence that Earth-like plate tectonics - great crustal plates pulling apart and crashing together - underpin the red planet's ...

Explore the Earth and Mars comparison to discover why Earth is the perfect habitable planet, uniquely sustaining life on ...

Mars had a global magnetic field much earlier—and much later—in the planet’s history than scientists have previously known. A planet’s global magnetic field arises from what scientists call a dynamo: ...

Like Earth, Mars once had a strong magnetic field that shielded its thick atmosphere from the solar wind. But now only the magnetic imprint remains. What's long baffled scientists, though, is why this ...
