Japan Aerospace Exploration Agency has launched Tokyo-based startup Star-ALE’s mini-satellite aimed to deliver the world’s first artificial meteor shower. The satellite carries 400 tiny balls, will be enough for 20-30 events, that will glow as they rush down the atmosphere on being released. ALE plans to deliver its first show in Hiroshima in early 2020.

It works by releasing the balls into the Earth’s atmosphere to prompt a process known as plasma emission that simulates a meteor shower for people on the ground up to 200km away.

Once they have lit up the sky, the balls burn up completely to not pose a risk to people on the ground. 

An exact date for the display is yet to be announced, with a second micro-satellite set to launch later this year.Beyond the micro satellites, ALE hopes to eventually propel disused satellites into the atmosphere for even brighter displays. 
 
meteor shower is a celestial event in which a number of meteors are observed to radiate, or originate, from one point in the night sky. These meteors are caused by streams of cosmic debris called meteoroids entering Earth’s atmosphere at extremely high speeds on parallel trajectories.
