A 60 thousand! The artificial meteor shower made in Japan can be staged all over the world.

Japan plans to be at the Olympic opening ceremony.

Create an "artificial meteor shower".

The event will be run by Japanese startup Star-ALE.

It is planned to develop a set called Sky Canvas.

Artificial meteor shower show,

To replace the traditional fireworks link.

ALE’s research and development can make artificial meteors

The ALE-1 satellite has a length and width of 60 cm,

It is about 80 centimeters high and weighs about 68 kilograms.

After the satellite enters the designated orbit,

Can be released in space with a diameter of about 1 cm,

Special metal particles weighing several grams,

When they enter the atmosphere, they burn to form a meteor shower effect.

And they can control the ingredients,

Form artificial meteors of different colors.

At an altitude of almost 70 kilometers from the ground,

The whole artificial ball has been burned.

Netizen: I really know how to play.

Others questioned:

This meteor shower has no soul.

What about the space junk made?

Recently, ALE representative in charge of this development work

Okashima Rina was interviewed by Japanese media.

Some hot issues were answered.

Okashima Rina pointed out that there will be some concerns about space junk, but we will try our best to make full preparations to avoid this phenomenon. Many people may think that meteors are very big, but they are actually very small things. The particle (diameter) of meteors is about 1 cm.

Okashima Rina also said that in fact, compared with natural meteors, artificial meteors glow for a longer time.

So, can you say three wishes to an artificial meteor?

Okashima Rina gave a positive answer: "It can be said".

ALE said that according to the orbit of the satellite,

This kind of artificial meteor can be staged on demand all over the world.

It can be seen in a designated area with a diameter of 200 kilometers on the ground.

It is estimated that the first "artificial meteor shower" will be created over Hiroshima, Japan in the spring of 2020.

It is reported that an artificial "meteor" costs 60,000 yuan.

Watching an "artificial meteor shower" will cost 60 million yuan.

According to Japanese media reports,

Orders have been booked from the Middle East.

Used for children’s birthday celebration.

Compared with natural meteors,

Artificial meteors glow longer,

The brightness will be comparable to that of a negative first-order star.

According to reports,

ALE-1 satellite can release 5 to 20 particles at a time.

The viewing time of each artificial meteor produced is 3 to 10 seconds.

It seems that in all kinds of movies and animations,

The scene of making a meteor debut is about to become a reality.
