Though Mars lacks a global protective magnetic shield like that of the Earth, strong localized magnetic fields embedded in the crust appear to be a significant barrier to erosion of the atmosphere by ...

A new study strengthens the theory that Mars’ magnetic field, which once supported a life-enabling atmosphere, may have lasted longer than previously believed. While the Red Planet is now cold, dry, ...

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

New research from the University of Colorado at Boulder reveals that areas of the surface of Mars may be protected from the full force of solar radiation by areas of intensely magnetized crust. The ...

NASA’s latest mission, designed to study the effects of the solar wind on the atmosphere of Mars, was ironically delayed on ...

Mars' global magnetic field may have hung around for 200 million years longer than scientists had thought, possibly giving life a longer window to take hold on the Red Planet. When you purchase ...
