“I had thought the iron core was solid, thus the lack of protective magnetosphere.”

Maybe this discovery improves the chances of terraforming Mars, to be more suitable for habitation.

I also saw somewhere else, before this liquid core information came in, that it could be feasible to orbit an big electromagnetic shield generator, that could divert enough of the solar wind, to protect an atmosphere on Mars.
