Basic Space Fact - Mass Protects Against Radiation Better Than Magnetospheres

Mark Eby — 9/8/2006 1:35:31 AM (archived)

Thats especially true of water for solar flare type radiation which our magnetosphere does stop. Our atmosphere stops cosmic rays not the magnetosphere and it only takes 15 lbs/in2 of rock or water to have the same mass equivalent.

That's all aside from the question of why you assume these worlds wouldn't have a magnetosphere.

Mark
