Mars' magnetic field may have survived 200 million years longer than scientists had thought — crucially, long enough for it to overlap with the presence of liquid water on the surface of the Red ...

NASA's Perseverance rover isn't just hunting for signs of ancient life on Mars, it's also testing spacesuit materials right ...

With evidence pointing to serious kidney challenges, careful planning will be needed to keep crews healthy on space journeys ...

Mars also lacks an active plate tectonic system, the geologic engine that drives our active Earth, and is also missing a planetary magnetic field. The absence of this protective barrier makes it ...

Unlike Earth, Mars lacks a global magnetic field and interacts with the solar wind directly. Over billions of years, this interaction has stripped much of the Martian atmosphere, transforming the ...

It is thought that Mars may have once had a protective magnetic field, and that its loss led to the erosion of Mars’ atmosphere. A magnetic compass works by indicating the direction of the north ...

NASA’s Perseverance rover is testing spacesuit materials on Mars to help scientists design gear for future astronauts.

Space is a harsh environment with dangerously high-energy radiation, especially from the sun. We are protected from most of this radiation thanks to our planet’s atmosphere and magnetic field, known ...

At left is NASA's Perseverance Mars rover, with a circle indicating the location of the calibration target for the rover's ...

While Earth's atmosphere and magnetic field protect the planet from these solar events, Mars has no such protection. But the sun's solar particles could be a boon for studies of — and travel to ...
