Is there anything stopping you from putting 2+ satellites out "closer" but in the path of the lensed light, capturing the light simultaneously, and then resolving the image via async computation later? I think this is called interferometry and I know it's hard because you need _very_ precise timing, but I'm curious if that would be possible or not. (Maybe you can get the timing in sync with atomic clocks, or by sending a laser to both from a central point that lets them keep time with some very tight tolerance?)

Weird idea but I wonder if there are ways to take this from "crazy tech" to "hard tech".

On a cosmic scale what does simultaneously mean? Two object in a distinct orbit will be in different planes of reference

Presumably it means that two light rays that leave the same point on the planet simultaneously (but going in slightly different directions) arrive at the two telescope satellites simultaneously
