Did Mars Once Have A Magnetic Field at Jett Loretta blog

Did Mars Once Have A Magnetic Field. Billions of years ago, mars lost its magnetic field. It’s also thought to have once powered mars’s magnetic field but no longer and not for more than 3 billion years: Research led by the university of tokyo and published in 2022 in nature communications offers one reason why: The loss of its magnetosphere was catastrophic for mars. The red planet once had an ocean and a magnetic field. Mars has a weak remnant of a magnetic field emanating from its crust, but it’s a feeble phenomenon that provides little protection. Magnetism in certain rocks on mars' surface indicate that the martian dynamo was active between 4.3 and 4.2 billion years ago, but the absence of magnetism over three large basins. Associate professor roger fu and graduate student sarah steele have uncovered evidence that mars had a global magnetic field, much like earth’s, for hundreds of millions of years longer than was once believed. Now, fragments from a famous martian meteorite, studied with a new kind of quantum microscope, have yielded evidence that the planet’s field persisted until 3.9 billion. A new mission is setting out to discover what happened to them. 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.
