So these numbers represent the potential for starship at its peak. even in the unlikely event these numbers end up being off by a factor of 10 that would only make the sls 100x more expensive rather then 1000x more expensive. The cost savings would allow public space to focus on making and launching more nuclear ships, maybe hundreds, rather then paying out the ass just to get a couple ships to space. Spacex is going to mass produce the starship like it was an automobile, the plan is for a starship to roll off the assembly line every 72 hours. Every 72 hours a new starship capable of launching 3 times a day every day for years, thousands will be built do you not get it?
People are sleeping on this because they can't wrap their heads around the absolute scale of it, the brain simply refuses to accept it, we've been so conditioned for low expectations, happy with a couple space telescopes every few decades and maybe 2 or 3 rovers on mars, a few flybys. That's not a space age, that's a few toys and some neat pictures.
The approximate total mass to orbit, everything put into space, throughout the entire history of space travel to the present day is roughly 15 million kg. A thousand starships launching 3x a day could put that much mass into orbit in 2 months. 70 years worth of payload capacity in 2 months. 6 times the entire history of man in space every year. 60x times everything put up there so far in a decade.
There is essentially no limit, the public space program won't have to hold itself back anymore. All the space telescopes and space stations and nuclear whatevers, rovers, human colonies. Whatever the fuck we can come up with and build we can now afford to put it up there. That is a space age, and we're on the cusp on it now.
