proposing that the magnetic shield remained active for several hundred million additional years. Using crater simulations, the researchers suggest that Mars’ magnetic field may have only started ...

Jim Green, the former head of NASA's planetary science division, has proposed building an artificial magnetic shield for Mars to protect a hypothetical nascent atmosphere from the sun's proton ...

This suggests that chorus waves can also be generated by changes in the frequency of the magnetic field ... “If you try to go from Earth to Mars, you need a lot of shielding. This is a new source of ...

Mars had a magnetic field surrounding it — the "dynamo." Mars' dynamo was "driven by convection within the planet's iron core much like Earth's," and "could shield the surface from harmful ...

The surface in Mars' northern and southern hemisphere is dramatically different. A groundbreaking study may have solved the 50-year-long mystery troubling scientists as to why one half of Mars is ...

TASS/. An artificial electromagnetic shield could reliably shield a crewed spacecraft from cosmic radiation during a flight to Mars, Doctor of Biological Sciences, Head of the Experimental Biology ...

As the time line at right shows, hundreds of times in our planet's history the polarity of the magnetic shield ensheathing the globe has gone from "normal," our current orientation to the north ...
