'Disco ball' put into space from NZ

A highly reflective sphere has been placed in orbit by a New Zealand-launched rocket. Akin to a giant "disco ball", the object should be visible to the naked eye as it sweeps across a twilight sky. It was lofted by American start-up Rocket Lab, whose Electron boosters operate from the North Island. The company said its "Humanity Star" was an attempt to create a shared experience for everyone on Planet Earth.

The Humanity Star is a geodesic sphere constructed from carbon fibre with 65 highly reflective panels. Circling the Earth every 90 minutes, it should be most visible in the darkened sky when the setting or rising sun shines up from below the horizon to catch the spinning ball's surface.
These are the same observing conditions that offer the best view of the International Space Station when it comes overhead. It shines brightly because of its huge solar arrays.
