    • According to a report, Tokyo-based ALE is set to launch the satellite in 2025 and it hopes to give people all over the world “the opportunity to view the world’s first live human-made meteor shower.”

    About

    • The project is called Sky Canvas and it is designed to collect atmospheric data in the mesosphere, which is the third layer of the atmosphere. 
      • The Mesosphere is too low to be observed by satellites and too high for weather balloons or aircraft.
      • The mesosphere lies between the thermosphere and the stratosphere
    • ALE hopes to reproduce the effect of natural meteor showers by using metal “shooting star” particles that are around 1 centimetre in size.

    Meteor Shower

    • A natural meteor shower happens when our planet passes through the trail of debris left by a comet or an asteroid.
    • Meteors are chunks of rocks and ice that are ejected from comets as they orbit the Sun.
    • Around 30 meteor showers that are visible to observers on Earth occur every year and some of them have been observed for centuries. 
      • For example, the Perseids meteor shower, which usually happens every year in August, was first observed about 2,000 years ago and was recorded in Chinese annals.
