Space assets offer services of social and economic benefit for humankind and enable monitoring the condition of our planet. As recognised by the UN and space agencies, space missions for Earth observation, geolocation, telecommunication, science, and technology contribute to the achievement of the Sustainable Development Goals. As our lives become more and more interconnected thanks to...

32. A Tiered Approach to Space Debris Mitigation Policy

There are numerous space debris mitigation policy documents around the world, ranging from national and international policy to agency-level policy. In most cases, rules designed to mitigate the impacts of debris are “one-size-fits-all” rules applying to all operators equally. As traffic levels grow and space becomes more congested, current rules may not suffice and will need to be made more...

47. Development of risk assessment tools at the University of Padova

In recent years, the problem of space debris has reached a critical level, requiring new and continuously updated mitigation tools. It is essential to develop impact risk assessment methodologies supported by accurate physical models, enabling more reliable satellite platform design. At the same time, up-to-date environmental models are crucial to provide realistic, high-resolution risk...

50. Autonomous collision avoidance algorithms as enablers for space congestion management

Dr Juan Luis Gonzalo (Universidad Rey Juan Carlos)

Even with the adoption of increasingly more demanding regulations to curb the generation of debris by space missions, both during operations and at end-of-life, the congestion of commercially relevant orbital regions such as LEO is expected to increase due to two main drivers. First, the existing population of debris will continue to pose a threat, and their number can keep increasing through...

51. Operational Long Term Assessment of Periodic Satellite Conjunctions

Achraf Mizmizi (Politecnico di Milano)

Periodic encounters arise from repeated close approaches between the same pair of objects, driven by their relative orbital geometry, and represent one of the main causes of Conjunction Data Messages. Due to their recurrent nature, these events can generate multiple conjunction notifications over extended time intervals, making their early identification particularly important for long term...

61. Space Debris Characterization Through Multiband Photometry

Alfredo Biagini (Osservatorio Astronomico di Palermo - OAPA)

03/06/2026, 17:30

Space debris are an increasing hazard for every kind space activities and a growing source of pollution. To date, research has primarily focused on a quantitative approach, monitoring the number and orbits of debris. However, characterizing individual objects could prove equally valuable — enabling the study of re-entry trajectories, associated risks, and, most importantly, the study of their...
