This post stems from a conversation I was having with Josh about the possibility of colonising Mars. I was saying how the major stumbling block would be finding a solution to the solar radiation problem since Mars is geologically dead. We’re protected from all the harmful stuff on Earth by the magnetosphere, which is generated by a spinning liquid iron core that basically acts as a giant electromagnet, but Mars’ internal dynamo – if it ever had one – ceased activity a long time ago. Josh then asked the following question:
“Could we restart it?”
Ahahaha. Ahahahahaha. Ahaha. No.
