If some sort of event (nuclear war, giant asteroid, whatever) killed everyone on Earth then everyone who lived in a theoretical colony on Mars would die too. Maybe not immediately, but the gulf between our current capabilities and what it would take to build a permanent self sufficient colony on a planet like Mars is absurdly large.
- seanflyon 12y agoIt is possible to build a self sufficient colony on Mars and it is also Elon's stated intention. It is not an easy task and we will have a permanent colony before we have a self sufficient one, if we have a colony at all. 66 years passed between the Wright brothers first powered flight (which lasted only 3 seconds) and landing a man on the moon. That is a huge gulf in technology. Perhaps we will have a self sufficient Mars colony in another 66 years.
