Ping Pong Comets

A cartoon star trailed by a pink flash against a galaxy

Event schedule details

Saturday 15 & Sunday 16 June


Event location details

Space Zone

City and Guilds Building, Imperial College London

Decorate your own icy balls of celestial shrapnel and watch their tails stretch out behind them as they face the solar wind.

Comets are near-pristine objects formed at the same time as the Solar System. As well as lighting up our night skies with their long tails, they may have also brought water and building blocks of life to Earth.

At the Great Exhibition Road Festival you can make your own with members of European Space Agency’s Comet Interceptor mission, which is due to launch in 2029, and aims to catch up with, analyse, and 3D-map a comet in unprecedented detail. The team will be helping families make and decorate their own Comet Interceptor targets using ping-pong balls and tissue paper before using them to demonstrate how a comet’s famous tail forms when they come close enough to the Sun.
