SpaceX is facing two big obstacles. First, going to Mars requires refueling in orbit, and that's not trivial to accomplish. Secondly, if they have to wait months between test launches due to regulatory issues, that's going to slow them down considerably.
- jfengel 2y agoThey're already working on refueling in orbit. A key stage of it was tested during the last Starship flight. It's not easy, but they're under contract to do it for their lunar landing. They're counting on Starship launches being like the Falcons. If they can get the regulatory issues worked out, it will be a regular thing. They've shown that it works for the Falcons. If they can't solve that they will indeed be in trouble, but I've got no reason to think that will go on indefinitely.
