You can adjust the decimal places here and there, but basically if you're talking about chemical rockets, there's a certain way you're going to go to Mars.” - John Aaron[1]

Neither Elon Musk nor Anybody Else Will Ever Colonize Mars (defector.com)
Mars does not have a magnetosphere. Any discussion of humans ever settling the red planet can stop right there, but of course it never does.

Neither Elon Musk nor Anybody Else Will Ever Colonize Mars (defector.com)
Mars does not have a magnetosphere. Any discussion of humans ever settling the red planet can stop right there, but of course it never does. Do you have a low-cost plan for, uh, creating a gigantic active dynamo at Mars's dead core? No? Well. It's fine. I'm sure you have some other workable, sustainable plan for shielding live Mars inhabitants from deadly solar and cosmic radiation, forever. No? Huh.
