SpaceX plan is very, very, very different from "Mars Direct". It basically shares absolutely nothing of the architecture other then the idea that ISRU is important. And what Mars direct, ie transporting hydrogen to mars, will absolutely not work for SpaceX. > But the SpaceX plan doesn’t require the astronaut return on the first Synod, or on any fixed schedule. Very unlikely that SpaceX or NASA would leave anybody there for two terms in a row.
