Japan satellite blasts into space to deliver artificial meteors

A rocket carrying a satellite on a mission to deliver the world's first artificial meteor shower blasted into space on Friday, Japanese scientists said.

A start-up based in Tokyo developed the micro- for the celestial show over Hiroshima early next year as the initial experiment for what it calls a " on demand" service.

The satellite is to release tiny balls that glow brightly as they hurtle through the atmosphere, simulating a meteor shower.

It hitched a ride on the small-size Epsilon-4 rocket that was launched from the Uchinoura space centre by the Japan Aerospace Exploration Agency (JAXA) on Friday morning.

The rocket carried a total of seven ultra-small satellites that will demonstrate various "innovative" technologies, JAXA spokesman Nobuyoshi Fujimoto told AFP.

By early afternoon, JAXA confirmed all seven satellites had successfully been launched into orbit.

"I was too moved for words," Lena Okajima, president of the company behind the artificial meteor showers, told the Jiji Press agency.

"I feel like now the hard work is ahead."

The company ALE Co. Ltd plans to deliver its first out-of-this-world show over Hiroshima in the spring of 2020.

The satellite launched Friday carries 400 tiny balls whose chemical formula is a closely-guarded secret.

That should be enough for 20-30 events, as one shower will involve up to 20 stars, according to the company.

ALE's satellite, released 500 kilometres (310 miles) above the Earth, will gradually descend to 400 kilometres over the coming year as it orbits the Earth.

Worldwide meteor shower shows

The company plans to launch a second satellite on a private-sector rocket in mid-2019.

ALE says it is targeting "the whole world" with its products and plans to build a stockpile of shooting stars in space that can be delivered across the world.

When its two satellites are in orbit, they can be used separately or in tandem, and will be programmed to eject the balls at the right location, speed and direction to put on a show for viewers on the ground.

Tinkering with the ingredients in the balls should mean that it is possible to change the colours they glow, offering the possibility of a multi-coloured flotilla of shooting stars.

Each star is expected to shine for several seconds before being completely burned up—well before they fall low enough to pose any danger to anything on Earth.

They would glow brightly enough to be seen even over the light-polluted metropolis of Tokyo, ALE says.

If all goes well, and the skies are clear, the 2020 event could be visible to millions of people, it says.

Okajima has said her company chose Hiroshima for its first display because of its good weather, landscape and cultural assets.

The western Japan city rose from the ashes after the 1945 US atomic bombing and faces the Seto Inland sea where the floating gate of Itsukushima Shrine is.

ALE is working in collaboration with scientists and engineers at Japanese universities as well as local government officials and corporate sponsors.

It has not disclosed the price for an artificial meteor shower.

There should be a universal convention on the prevention of man made light pollution. Another stupid use of space.

Sounds like a really bad idea, who knows what effects burning that secret chemical formula high up in the atmosphere has, and they want to go ahead and do it all over the world...

Do not look at the bright lights

The day of the triffids has arrived
If the Japanese want to pay to entertain
the world for free, it's their money
Just do not look at the firework display

you wait & see. Anyone complaining will be accused of being a tree-hugging marxist girly-man.

Some rich guy wants to show off by pissing fireworks all over the world. How dare any regulator deprive him of that entitlement?

Besides all the altright fairytails get off on being pissed on. This'll be cheaper than a Moscow whore?

"If all goes well, and the skies are clear, the 2020 event could be visible to millions of people, it says."

"IF ALL GOES WELL" seems like a clear indication that they're not too certain that this little scheme of theirs will not have a repercussion or three.
I agree with granville: don't watch the lights from their display. Who knows what it might/will do to your eyes.
No one has yet said that it could exacerbate AGW.
