- Q. What causes the meteor particle to glow?
- A. A natural meteor 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 meteors.
The meteor will travel one-fifth of the way around Earth before entering the atmosphere and visibly glow. When glowing, the meteor can be seen in an area up to 200km in diameter.
- Q. Is there anything that sets apart the man made meteor from natural ones?
- A. Compared to a natural meteor, the man made meteor travels more slowly and glows for a longer period of time.
- Q. What is the meteor particle like?
- A. The meteor source is a small 1cm sphere with a mass of a few grams.
- Q. In a given show, how many meteors can I expect to see?
- A. On average between 5-20 meteors; however, this number will vary depending on the details and content of the show.
- Q. How long will a meteor remain visible?
- A. Approximately 3-10 seconds per particle.
- Q. How bright will the meteor glow?
- A. We expect the meteor to have a maximum magnitude of -1. This allows for the meteors to be observed even in bright cities such as Tokyo.
- Q. How far above the surface willthe 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. Is there a risk of man made meteors hitting the surface?
- A. The meteor particles burn up completely at about 60 - 80km above the ground and will not reach anywhere near the ground.
- Q. Could the meteor crash into an airplane?
- A. Our simulation verifies that the meteor particle will completely burn up before an altitude of 60km. Because an airplane typically flies at an altitude of 10km, the meteor cannot hit airplanes.
- Q. What is the Sky Canvas Project?
- A. Sky Canvas is the world's first man made meteor 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.
