    i remember reading about this idea on the paper in the 80s. i think the loggistics of launching such a large structure to orbit, just achieve bad PR would be have terrible ROI

      No need to launch anything, just use a powerful projector aimed at the cloud layer.

      Like the Bat signal.

      I imagine if done irl it wouldn’t be one solid space structure, but instead something like a ground based projector operating on cloudy nights, projecting an ad into the bottom of the cloud layer, or if actually in space, an array of satellites that each act as a “pixel”, with a laser that they can shine at a city or location that they want the ad visible from.

        Fortunately for us, this wouldn’t actually work that way. Rather, each of the individual satellites would have a different orbit so the image wouldn’t remain consistent, but instead converge into a point and invert itself on the other side of the Earth before coming back together again and repeating this process until they start colliding with one another or decay into the atmosphere. That is, unless each “pixel” made constant adjustments throughout the orbit, which would be a colossal waste of fuel.

        Disclaimer: this is based only on my intuition from 780+ hours of Kerbal Space Program. I am not a scientist and I’ve never studied orbital mechanics.
