Reevaluating the idea of leaving Starships on Mars
A few days ago u/Col_Kurtz_ made a post advocating that starships sent to Mars should stay there as permanent structures. Some minor side issues took the topic off into the weeds but I think there is still a case for it: n+2:Where n = cargo Starships eg. 5 + 1 more cargo + 1 passenger variant. Once on Mars the Raptor engines, avionics and anything else of value SpaceX need for future Earth launches are striped from the 5 ships, put in number 6 and sent back to Earth. The passenger class ship serves for evac incase of need. Livabilty:Starships are readymade, erected pressurised structures with what will be proven life support systems already in operation. Suggestions of 18m diameter variant ships in the coming future makes for potential very usable living and working spaces. As radiation requires shielding, a 3D printed cladding of Martian soil could be erected to provide this. Coincidentally the video from the winner of NASA’s Mars habitat competition concluded a starship shaped standing cylinder maximises structural strength, usable living space and is “inherently the most printable shape [...] the smaller footprint aids in the printers reduced requirement for mobility”. Theoretically the nose cone could be removed, a printing arm attached and the the ship would effectively cocoon itself within its soil derived radiation shielding. Optimisation:Continuing with the 5+2 starship scenario, each ship would be equipped with the basic requirements to maintain the crew in optimal health over course of the journey but within each hold would be dedicated outfit for the in field operations so all ships once on Mars lose their berths and ship 1 installs its cargo load to become the dedicated crew living space. Ship2 becomes the laboratory, ship 3 the grow house, 4 the hangar, 5 the engineering bay etc. Rather than attempting to build and test ISRU “in the field” on Mars, much of the system would be hard installed into ships on Earth and flown out to be assembled much more easily on Mars. A flying Stirling engine, a flying co2 extractor etc. After all the simplest solution is often the best Cost savings:There are a lot of memes about “flying water towers” and “built in a field by welders”, but I think this is real game change that the switch from carbon composites to steel can allow. Going from $130/kg to $2.50/kg makes it so economical that you don’t save much flying the rocket body back. The labor and materials are cheaper than the fuel and the transport time. Less rockets coming back equals much lower demands on ISRU, and once you decide certain ships will only be decelerating and landing through Martian atmosphere, the door opens for furthe potential efficiency gains (altered heat shielding reqs etc). If it can be shown it’s easier to strip valuables off of ships on Mars and send them back to Earth than it is carrying habitation in the hold to Mars and constructing up there its a worthwhile exercise. Without the valuables its just a water tower, and once you can afford for the mass of the rocket itself to become part of the permanent infrastructure up there then you’re left with a massive efficiency win. Really could be SpaceX’s ace in the hole. Any obvious flaws?(Sorry to post twice, wasn’t sure which sub was more appropriate)

<b>I created an Open Source REST API of SpaceX webcast telemetry (for past flights and in real time)</b>
