astronomy today point to a small piece in the sky to measure some binary star that is barely one pixel on the sensor. now you covered it with a black satellite right when then unique event was about to happen... did it not happen or was hidden by a new satellite?

also, black coating is old news. very old news. and musk said he didn't consider for starlink because he doesn't have to pay for something that doesn't make money directly for himself. so this whole discussion is pointless.
