> Is this feasible at all? From an engineering perspective: absolutely! There's still some major hurdles when it comes to propulsion, communication, and station-keeping, but the basics are all there already. The sad part is that such telescopes would cost a lot of money. I mean a lot of money. From a pure engineering perspective I would image 20-30 years and we'd have such telescope. I'm not at all optimistic about the budget part, though, as NASA and the US private sector have been fixated on Mars for the past five decades. ESA is too disjointed for such project (22 + 5 member nations and associated nations), the Chinese are busy claiming the Moon, and the Russians are broke and never made it to the outer solar system anyway...
