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

Lena Okajima, CEO of a space technology venture ALE is hoping to deliver shooting stars on demand and choreograph the cosmos

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.

The annual Perseid meteor shower—seen here over eastern France—is a highlight for sky-watchers

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.
