Q. What causes the shooting star particle to glow?
A. A natural shooting star is caused by plasma light emission when dusts of various size rush into the Earth's atmosphere.
ALE artificially replicates some of the smaller space particles and releases them from a specially designed satellite to create man-made shooting stars.
The shooting star particle will travel one-fifth of the way around Earth before entering the atmosphere and visibly glow. When glowing, the shooting star particle can be seen in an area up to about 200km in diameter.
Q. Is there anything that sets apart the man-made shooting stars from natural ones?
A. Compared to a natural shooting star, the man-made shooting stars travels more slowly and glows for a longer period of time.
Q. What is the shooting star particle like?
A. The shooting star particle is a small 1cm sphere with a mass of a few grams.


Q. How far above the surface will the satellite travel?
A. About 400km above the ground.
Q. What happens to the satellite once it is no longer in commission?
A. Once the satellite is out of commission, it will re-enter the atmosphere and completely disintegrate to prevent from becoming space debris.


Q. What is the Sky Canvas Project?
A. Sky Canvas is the world's first man-made shooting star project, aiming to bring people all over the world together to witness an unprecedented, collective experience. Using space as our stage, we will constantly strive to bring to life new levels of entertainment while utilizing its technology in the development of science.
