This has already been proposed for shielding the entire planet Mars, see https://www.popularmechanics.com/space/moon-mars/a25493/magnetic-shield-mars-atmosphere/ https://www.popularmechanics.com/space/moon-mars/a25493/magn... (2017). I'd love to see SpaceX take a crack at this, conceivably it would amount to launching a modified MRI into Mar's L1. It's actually within the launch capability of Falcon Heavy so it's something they could start working on now.
- elcritch 6y agoThat's amazing! Even a few shipment of neodymium magnets could be sent. Then in a 1,000 years after the collapse of our civilization and emergence of a new technological civilization there'd be a Mars with much thicker atmosphere and potentially even liquid water. Even for regular human asteroid mining it looks like an artificial magnetosphere would be possible: https://physicsworld.com/a/magnetic-shield-could-protect-spacecraft/ https://physicsworld.com/a/magnetic-shield-could-protect-spa... It's still surprising to me that the notion isn't prevalent in sci-fi or even hard sci-fi. Though as you mention even a modified MRI could do the job.
