How good a telescope would this be?

Question

with a 1000 meter diameter.
would it go good on a space station?

Answer 1

Sounds hypothetical. That would be an awesome scope but how would you build it? You cannot create a lens of that size and the largest reflectors on Earth are made of multiple mirrors that all have to work together very precisely (the Keck in HA). I just don't think it could be created.

Answer 2

Hi. That is a HUGE size scope. It may work well for radio signals on the Moon, but not in space.
