To add on to what everyone else is saying, compared to the Apollo capsules, Starship is fucking HUGE. Apollo 11’s capsule was 10 feet tall by 13 feet in diameter. Starship is 180 feet tall not including the launch vehicle.
Edit to add: Mercury was literally just an ICBM with a dude strapped on top, with Saturn V being based on that design. We’re only now beginning to make designs that are actually made just for space travel.
Not to mention, it’s a standard now, and the old Supercharger protocol is being phased out in favor of another standardized one (I forget which). Further development done on their chargers from here on out is going to be done by a consortium of companies rather than in-house anyway.
