The latest article about the HST has me wondering. http://www.space.com/businesstechnology/technology/hubble_ngst_010817-1.html The article mentions major surgery that would be required to boost the capabilities of Hubble up to standards. That surgery would require a special shuttle trip, etc. etc. Why not add the HST to ISS? That way any surgery could be done by the ISS crew, with regular work being done any time it needs to be?

Too many vibrations. ISS jiggles too much. When Hubble snapped its
"Deep Field" view a few years ago, it looked at the same patch of sky for a
very long amount of time ( I think >24 hours ).

Well, you don't have to actually attach the Hubble to the ISS. The
real problem is the orbit. Have you noticed on the ISS updates that
NASA puts out, that every time the shuttle is docked it boosts the
ISS orbit up a few miles? That's because the ISS is in a low,
decaying orbit. And as the mass of the ISS grows, the drag will
increase while the capability of the shuttle to boost the ISS
decreases. Heaven forbid we ever have another serious shuttle
problem; that Soyuz return capsule will actually get used.
