This project focuses on the systematic characterization of artificial space objects—including satellites, debris, spacecraft, and large satellite constellations—and on assessing their impact on astronomical observations. Following the strategic frameworks established by the EU Space Surveillance and Tracking (EU-SST) network and the IAU Centre for the Protection of the Dark and Quiet Sky from Satellite Constellation Interference (IAU CPS), the project aims to contribute to global efforts that ensure the long-term sustainability of both space operations and ground-based astronomy.

The work includes monitoring and analyzing the physical, photometric, and orbital properties of space objects; modeling their brightness and variability; and quantifying their influence on astronomical data quality. A specific line of research will investigate the impacts of satellite megaconstellations on key scientific research programs—such as wide-field surveys, transient detection, cosmological experiments, and radio astronomy—evaluating both current and future risks.

The project will also develop methodologies to mitigate observational interference, support policy-relevant recommendations, and enhance coordination between astronomical institutions and space-traffic management entities. Through these activities, it seeks to strengthen international capabilities for responsible space stewardship while safeguarding the scientific potential of the night sky.
