They would deorbit after 1-3 months, depending on several factors. The 50 satellites could rearrange themselves in patterns, from letters to simple graphics - not fast, but fast enough that the shape could evolve over their visible time, or change advertisers between target cities. (To be clear, the image at top is just for illustration - it would be much dimmer in reality.) These could be tilted to best present the sunlight to a target area they are passing over, and from the ground would appear to be a group of stars moving in synchrony for a period of perhaps three to five minutes. ![]() Once in orbit, they would deploy large, parabolic reflectors that would bounce sunlight down toward the Earth. The satellites would enter a sun-synchronous orbit, meaning they’ll always be in direct sunlight as they pass around the Earth. The paper’s proposal involves sending up a constellation of about 50 satellites at a 12U CubeSat volume - think about the size of a full paper grocery bag. The study, from Russian researchers at the Skolkovo Institute of Science and Technology (Skoltech) and Moscow Institute of Physics and Technology (MIPT), presents a fairly compelling case that is bolstered by the recent controversy around SpaceX’s highly visible Starlink satellites. ![]() Of course, just because they could doesn’t mean they should. A new study suggests that a billboard-like constellation of about 50 satellites, costing $65 million all in, could shine ads to every corner of the Earth for months - and potentially make money while doing so. ![]() Space-based advertising has been on the minds of every marketer on the planet since the Apollo era, yet no one has made it happen.
