Personally, I'm not a huge fan of the ISS either -- but that's not to say I would turn down an invitation to visit her in orbit!!

Anyway, I do agree that the physical science run on the station-proper is far too limited, with constraints requiring size, weight, and packaging (i.e., money), not to mention astronaut expertise in the desired experiments, being the greater hindrances.

I think many here would agree that the station should come down, and be replaced with serious flights outworld to the Moon and Mars, for hard studies in the idea (really more a dream than an idea) of humanity’s ascension to the stars.

As I’ve said before, like architecture, LEO has now become more an art than a science,
