A scary thought: orbital ads hovering over major cities.

In a new paper published in the journal Aerospace, researchers from the Moscow-based technical institute Skoltech and the Moscow Institute of Physics and Technology concluded that sending a formation of satellites into orbit to display commercials above population centers could not only be feasible, but cost a mere $65 million per mission.

Each individual "pixel" or satellite of the space billboard would have to be pretty massive to reflect enough light and make the whole thing financially feasible. One researcher suggested each cubesat satellite could be as large as a 350-square-foot solar sail, referencing the area of LightSail 2, the largest solar sail to have ever been sent to space so far.
