The research on humans in 0 g is only relevant if you want to send humans to mars. And such a mission is likely to end up being an ISS on mars. Or a moon landings reboot. A lot of newsprint and bandwidth expended talking about it. A small amount of science that could have been done more cheaply with a robot. And then everyone gets bored, they play golf on mars and people look at the bill and go “was that really worth it?”
Oh and you would contaminate mars with earth bacteria.
A substantially bigger, redesigned space station is fairly likely to be somewhat more expensive. And the point of all this is still not clear.
Current day NASA also happens to be in a failure mode where everything is 10 to 100 times more expensive than it needs to be, projects live or die based on politics not technical viability, and repeating the successes of the past seems unattainable. They aren’t good at innovating, especially not quickly and cheaply.
