What else can you hit at the opening of the next Olympiad? And then the Japanese remained true to themselves. During the opening ceremony of the Olympic Games 2020 in Tokyo, they promise instead of the traditional fireworks to arrange … artificial meteor shower.

For this hard business decided to take a start-up Star-ALE. According to its creators, a grand pyrotechnic show called “Heavenly Canvas” will be visible in the district at a distance of more than 190 km.

Ordinary meteoric rain occurs when particles of a few millimeters in size fall into the dense layers of the atmosphere, where they burn with the formation of bright plasma emissions.

Colors

To create an artificial meteor shower, startup participants intend to put into orbit a special microsatellite with 5000-10000 combustible pellets from various metals. When burned, they will emit different colors . For example, potassium burns violet, cesium – blue, and copper – a green glow.

The falling granules should flare at an altitude of 35 to 50 km above the Earth. There is no doubt that, if successful, we will witness an unforgettable, colorful heavenly show. Currently, Star-ALE participants “roll” the pellets in a vacuum chamber.
