Shooting stars from space for 2020 Olympics
When the 2020 Olympics gets underway in Tokyo, Project Sky Canvas hopes to paint the sky above with shooting stars.
The plan is to put a micro-satellite in orbit that will fire tiny particles into the atmosphere.
As they fall to Earth they will burn up and become on-demand shooting stars that can be directed to any chosen location and be seen within a radius of up to 200km (124 miles).
