Study sees a future in cubesats fleets forming ads in night sky

A Russian study claims that flying a formation of cubesats to create adverts in the night sky could be economically viable, with each solar sail-carrying satellite projecting a pixel of a message to cities below.

The study, by a team of researchers from Skolkovo Institute of Science and Technology in Moscow and the Moscow Institute of Physics and Technology, looked at the use of 344 square-foot (32 square meters) solar sails that would be attached to the cubesats and angled to reflect sunlight, each forming a pixel in the sky. Such large reflectors have never been deployed on cubesats before, but the study found the solution feasible, concluding that a fleet of 50 such satellites would be ideal for such advertising campaigns. When passing overhead above a target city at altitudes of between 300 to 600 miles (500 to 1,000 kilometers), the formation would light up, displaying bright messages to the residents below.
