That is a cool search. Thanks! There does seem to be some mention of the implications you raise in the article under that ‘House on Mars’ section, with some handy links out to research expanding on this topic. I got too excited and perhaps should have started there. But it was your passion and sincere questioning that really made me think. Inspired by your response, I found this paper while originally focused on mini magnetospheres for spacecraft might be adapted for the surface. I read of one earlier paper discussing a sphere extending to 1000 km but we’d likely just need 10km especially if it was mobile?

The evidence that mini-magnetospheres can effectively interact with bulk plasma in space is supported by observations of magnetic anomalies on the Moon (Bamford et al., 2014), around asteroids and comets, both natural and artificial. Laboratory experiments and simulations further suggest that mini-magnetospheres can significantly impact the high-energy distribution of charged particles, providing optimism for their use as radiation shields in space exploration (Bamford et al., 2014).

Would love more of your critique or insights. There more objections, the more informed we are. Have you done any writing on Mars Exploration. I’d definitely read it if you do. I’ll go look now so that you don’t have to send me a search query. Thanks!
