This thesis is a early phase design of a space mission in which the goal is to develop a service that, based on small satellites, is able to address the wildfire problem in the Mediterranean area with reliable fire forecasting and active monitoring. Wildfires are becoming a serious issue in the Mediterranean area, as in 2022 more than 2700 fire events caused an area loss of more than 800 hectares, with a trend that is rapidly worsening. Major initiatives to tackle this phenomenon are taken by the Copernicus programme of the European JRC, in which is developed the idea of using remote sensing as a tool for rapid mapping to support rescue teams in case of natural disasters as wildfires, but there’s still some gap in the current operational approach.
