> surely there must be already a lot of trade studies on the next steps, and at least some rough plans. Starship was always designed to refuel in Earth orbit, land on Mars, refuel on Mars and fly back to Earth in a single stage. This kind of architecture has never been attempted before and it has a lot of long-term implications for the design, for example the same reentry maneuver must work on two planets and orbital refueling is mandatory. All other rocket designs consider "planetary landing" as something for the payload to worry about.
