Via the inestimable Super Punch comes news of a company in Japan that will be able to deliver shooting-stars on demand.
These pyrotechnics of course are a bit more of a challenge than conventional fireworks, with orbiting satellites coming into position carrying a payload of pulverised metals to give an Earth-bound audience a dazzling show. These planned displays—though the Cosmos is pretty reliable as well when the Earth passes through the tail of a comet, provided one has a little patience and dark skies—of meteor showers can even be configured to rain down in different colours—using the same chemistry that’s behind traditional sparklers. Late-2017 is supposed to see the first show and the company will figure into Tokyo Summer Games of 2020, but there are practical applications as well, including clearing away some of the orbiting debris that we’ve accumulated.
