Tokyo-based ALE has created microsatellites that release tiny spheres that shine brightly when they penetrate the atmosphere and simulate the dazzling spectacle of a meteor shower. The chemicals involved are evidently a closely guarded secret, but each satellite can carry 400 balls – enough for 20-30 meteor events – to tinker to produce multicolored "stars". Each star will burn for several seconds before it is completely burned, long before they are close enough to Earth to be dangerous.
The first satellite will be catapulted into space with a rocket launched by the Japanese Space Agency in March 201
The first show is to take place over Hiroshima, although the company says its meteor shower could easily be used anywhere in the planet, as the supply of "stars" is held in space. It's not clear how much a false meteor shower will cost, but since the company spends $ 20 million on the development and production of just two satellites, it probably will not be cheap.
