Planned EOL was 2013ish & "Investigations into extending ISS lifespan to 2028 started in 2010"
So... the controversy is replacing the program with something new after twice the initially planned lifetime? And 2028 was the extended EOL anyway?
So this was already planned... outside chance it could be 2030, beyond that would require megabucks investment per public info.
and...
This was never the intended space station and it's not in an orbit useful for anything other than international relations. (aka Russia can launch to it, would use too much fuel to get to a useful orbit - that said, maybe we avoided war due to the coordination required and the cost is justified on that basis - I don't have the inside baseball info to judge that one)
I support replacing the ISS with something in a useful orbit that has a more useful role, building on the lessons and experience gained with the ISS.
We're (the US) about to get two new private launch vehicles that are on track to be even more affordable. Starship with 'bigger than Saturn' lift and New Glenn roughly splitting the difference between Starship and Falcon. Small launch companies are trying to break into the light lift market as well.
I hope they all succeed.
Assuming they do...
We can put up a new station with 1/20th the inflation adjusted launch cost of the ISS and 1/50th of SLS (or less).
If practicality mattered, we should be making speculative plans for what new 'we couldn't before' thing we could be doing with the ISS funding as a replacement, then zero in plans once we have operational versions of those vehicles.
But... won't someone please think of the elected representatives with a net worth under 100mil? We can't disturb this 60 year long tradition of graft!
The political powers controlling the modern version of Project Mockingbird won't stand for it! Crazy the amount of GO funded NGOs involved. Wild tracking that activity starting since Tesla gained traction. (like the og Electric cars from Detroit are 'Green' but not Tesla)
