<b>[OC]: The potential advantages of a detachable passenger module for Earth to Mars transportation</b>
Hi all! I was thinking through the Starship architecture and it seems inefficient to me to have the majority of the mass and expense that is being transported between Earth and Mars tied up in hardware that is only needed at the ends of the trip, namely the huge Raptor engines, fuel tanks and heat shield equipment. It seems to me that the weight of those structures is conservatively about 90% of the total mass of Starship, and probably about the same proportion of the total expense, and it's completely unnecessary and potentially even harmful for the interplanetary journey. If instead, you had a dockable passenger module which attaches inside the Starship aeroshell for takeoff and landing, but is free during the trip to and from Mars, you can keep your expensive specialized rocket around a gravity well while sending only the cargo you actually care about on the months long journey. Basically, the architecture I propose can be summarized in 3 points:1. Keep the specialized hardware for entering and exiting an atmosphere as close to an atmosphere as possible.As Elon said in his presentation, they expect Super Heavy to be able to launch essentially at will, as much as 24 times a day. Starship should be able to launch 4 times a day. That means that while these ships are close to Earth (or Mars) you have enormous payload to orbit capabilities, at essentially the cost of fuel. If you send Starship to Mars, you're losing that capability for months, at an enormous opportunity cost and for really no benefit.2. Use one starship for multiple lauches <em>and landings</em> at each planetNot only is your expensive hardware located where it's useful, but it costs absolutely negligible DV to stagger the arrival time of a crew pod to Mars, so you could in theory launch and land at a defined interval, say two pods every day, using just ion engines on the crew modules (which would be far more effective with the far lower dry mass of the pods - more on this in the next point). That means that with lets say 4 starships on Mars, you could handle conservatively 4 passenger landings per day for the duration of the window, instead of needing a single starship per window. This would be <em>huge</em> for passenger throughput to Mars, and the same is true on launch. Throw passengers on their way, bring the ship back, repeat. The whole system could be 8 cargo starships <em>total</em> and a supporting fleet of tankers on the Earth side, for an essentially uncapped throughput of passengers, and the only hardware lost to deep space would be the relatively cheap and light passenger module itself.3. Have as much propulsion hardware as possible on the passenger module, rather than coming from the very heavy, EDL specialized starship.This is a little tricky because it gets into how much you actually want to engineer into the passenger stage, and therefore its dry mass (for example, adding a chemical rocket versus ion engines would make it more capable and have huge DV advantages for the entire system, but you have to figure out if you can fit that all in the Starship cargo bay, can it aerobrake, etc.) However, the more propulsion that is done on the low mass passenger vehicle, versus the very high dry mass Starship, the more efficient the overall architecture is, just like how GEO satellites that have their own fuel and propulsion much more efficiently use F9s capabilities than a direct second stage insertion to GEO, and that's the direction that the satellite industry has explored.Basically, as low dry mass as possible cycling between Earth and Mars means less propellant usage, higher utilization of the expensive parts of the system itself (namely Starship). The passenger module could also be more specialized for deep space, including ideally an inflatable component instead of the punitive space constraints of Starship itself. Finally, first and foremost this…
