Anons, ever since mars direct 2 I've pretty convinced that using starship as the only means of landing on and leaving mars is a not amazing concept due to the energy and mass requirements of acquiring the propellant needed for such a large vehicle, even with nuclear. Needing ISRU water to survive the mission is a massive risk and requires so much more mass to mine and transport and filter... Etc. While not perfected, I think this architecture has most elements that would allow the best chance of survival. Mars missions would be shut down if SpaceX has the first crew not survive.
