they're really two fundamental paths industry is going to bifurcate along two directions one one one path is we stay on earth forever and then there will be some eventual extinction event I don't have an immediate doomsday prophecy but there's it's eventually history suggest there will be some some doomsday event the alternative is to become a spacefaring civilization and a multi-planet species which I hope you would agree that is the right way to go yes so how do we figure out how to how to take you to Mars this is an actual scale of what the solar system looks like so we're we're currently in the third little rock from the left that's earth and our goal is to go to the fourth rock on the left that's Mars and if we get a cut the cost of moving to Mars to be roughly equivalent to a median house price in in the US which is around two hundred thousand dollars then I think the probability of establishing a self-sustaining civilization is very high I think I think it would almost certainly occur no not everyone who'd want to go in fact I think a relatively small number of people from earth would want to go but enough would want to go and who could afford the trip that it would happen there these are the key elements that are needed in order to achieve the four and a half order of magnitude improvements most of the improvement would come from full reusability somewhere between two and two and a half orders of magnitude and then the other two orders of magnitude would come from refilling in orbit propellant production on Mars and choosing the right propellants and then the propellant tank it goes up and actually it'll go up multiple times anywhere from three to five times to fill the tanks of the of the spaceship in orbit and then once the spaceship is the tanks are full the cargo has been transferred and we reach the Mars rendezvous timing as messages roughly every 26 months this is to give you a sense of size is quite big and the funny thing is I think in the long term the strips will be even bigger than this I think this will represent this will be relatively small compared to the Mars interplanetary ships of the of the future
