The successful launch of the Sustainable Development Science Satellite 1 (SDGSAT-1) by CBAS in November 2021 marked the beginning of the first science satellite program dedicated to supporting the 2030 Agenda. This presentation will provide an overview of the SDGSAT-1 mission. By delivering high-resolution data, SDGSAT-1 enhances the assessment of urban lighting patterns, industrial activity, and environmental changes, contributing to evidence-based policymaking and sustainable development initiatives. Through the SDGSAT-1 Open Science Program, its data is freely available to the global scientific community, accelerating Earth observation-supported SDG applications.
