You can attach a low-pressure (no boil-off in long flight to Mars) ethylene rocket [or 2 of them actually] to an outbound Mars-starship ROCKET You launch these separately on two Falcon 9s. Launching these will cut down the need for multiple Starship re-fueling tanker flights,
Already plenty of artifacts up there with which to build most of what we need to go or squat wherever. Straighten thatup first then moon or mars. All we really nd is a shielded workspace like lunar gateway. Until thats established nothing else can or should be. This aint like 1g trash. & trashig up mars aint helping anything. Has anything beyond lunar orbit been attempted to be coaxed back? This has longtime been argument for mars. That whatever donethere would help us backhere. Things didnt progress thatway. Yes mars gravity well & atmosphere are grt. For aerobraking human health etc. Just too dangerous now.
