>>10715108>Would they have to be as large as Earth-based telescopes due to lack of atmosphere?Radio doesn't get blocked by the atmosphere, but it does pick up local noise, which is why big arrays are in the middle of fucking nowhere.
Also, the bigger your collector, the bigger the radio waves it can receive. You can also daisy chain multiple telescopes into an array for an effective area of the widest points of the array.
If I had infinity money I'd build multiple linked arrays of multi spectrum telescopes. Radio and multiple visual bandwidths.
