Did Mars Have A Magnetic Field at William Biscoe blog

Did Mars Have A Magnetic Field. The mars global surveyor spacecraft confirmed this, but also found. But magnetic analysis of the martian surface indicates that when mars was a mere 500 million years old, its magnetic field withered away. But researchers can’t agree on when that happened. Mars, unlike earth, has no global dipole magnetic field. Mars has a weak remnant of a magnetic field emanating from its crust, but it’s a feeble phenomenon that provides little. Like earth, early mars had a magnetic field and perhaps an atmosphere conducive to liquid water. Research led by the university of tokyo and published in 2022 in nature communications offers one reason why: Without the protection that a magnetic field offered, the atmosphere was stripped, and eventually, the oceans evaporated as water vapor in the atmosphere was lost to space. At one time, mars had a magnetic field similar to earth, which prevented its atmosphere from being stripped away. Billions of years ago, mars lost its magnetic field. As the martian interior cooled, leading theories hold, its magnetic field died out, leaving the atmosphere undefended and ending this warm and wet period, when the planet might have hosted life.
