Japanese company ALE has been working on a new type of sky show, artificial shooting stars, literally creating an artificial meteor shower at a height of 40 to 50 miles (60 to 80km). The show will be visible to anyone within a 125 mile diameter area (200km), meaning that people in New York city and Philadelphia or Los Angeles and San Diego can watch the same show. Aptly named, they’re calling the project “Sky Canvas”.
The plan is to have a satellite, containing around 500 to 1000 source particles, discharge the particles with a specially designed device. As the video below shows, by ejecting the particles in a continuous manner, rather than all at once, they’ll create the equivalent of a meteor shower. The particles will travel around 1/3rd the way around the Earth before entering the atmosphere, creating the shower of shooting stars. Different colors will be possible by using different materials for the particles, something this fireball cannon illustrates.
