World's first man-made shooting star satellite
ALE's man-made shooting star satellites were developed together with Tohoku University.
Our satellites, ALE-1 and ALE-2 are both equipped with multiple sensors that measure attitude and position along with three independent controls making it extremely reliable. As a result, our satellites can release particles to emit light precisely at a designated location, can prevent collisions with other satellites and avoid producing space debris.
The meteor release device is a payload (mission system) built with Japanese craftsmanship such as highly precise processing technologies and high-quality components. Though the particles are released at a very high speed (maximum 400m/s), the error remains below 1%, which enables a safe and highly accurate generation of shooting stars on demand.
ALE's operation system and procedures ensure the shooting stars trajectory crosses Earth's atmosphere. Our meteor particles are released after confirming that there are no other spacecrafts on the designated path, which prevents space debris generation.
When entering Earth's atmosphere from an altitude of about 80km, the particles will completely decelerate and disappear due to air resistance and aerodynamic heating. Therefore, they will not fall on the ground.
