I’m not advocating cutting corners; but rather adding to capabilities at relatively low incremental cost. Modern concepts that appear to work include multi-purpose missions: involving both science and commercial interests, and maximizing what you can still accomplish when things go wrong.
If building a proper space station must be done before an interplanetary supply tug, then so be it. It’d be frustrating if ISS cannot be that station, but i do see your point about ongoing research agreements among the partner nations.
I totally agree that so many of these things, radiators and support technologies, radiation countermeasures, ships assembled in space,
should have occurred decades ago.
it seems to me, that swivels and hinges, and the motors to drive them, are low tech, low cost, and add a lot of capability.
