Galileo Galilei at the 30th anniversary of European satellite navigation

On 2 September 2025, ESA opened the doors of its research and technology centre to partners from across the continent to celebrate 30 years of European satellite navigation.

One of the most memorable moments of the celebration was the theatrical performance featuring Galileo Galilei and his imagined great-great-granddaughter Celeste, a satellite navigation engineer working at ESA. Together, they explored what the Italian genius would have thought of today’s navigation systems.
