- rbanffy 8y agoI call it a nice way to make a lot of money disappear without actually delivering a useful thing. You'd need to fly a huge fleet of precisely controlled cubesats in tight formation without the control jets of one interfering with the others while they are close enough to provide adequate pixel density from the surface. Their orbit should be high enough that they cross the sky in a pace slow enough to be seen. At 400 Km it's already quick. I once did the math that a Mylar balloon with 1 degree (the same apparent size of the moon) would need to be about one kilometer wide at a 110 km orbit. It'd weight ~30 tons at launch, without any added vehicle (an ion drive could keep it up for a longer time, until it gets punctured enough to deflate). That was about the maximum payload to LEO that the largest launcher of the time could handle.
