Ciseres: AI-powered satellites for rapid disaster response  

This week, at the International Aeronautics Congress in Milan, ESA officially kicked off a new project called Ciseres, a small satellite mission designed to significantly improve crisis response times using artificial intelligence (AI). Part of ESA's Civil Security from Space (CSS) programme, Ciseres aims to enhance satellite capabilities to alert first responders and government officials within minutes of the occurrence of a disaster – such as floods, fires, landslides. The project is led and co-financed by Deimos, a European space tech company specialising in small satellite missions.
