23. Extending the Polluter Pays Principle to Orbit: The Legal Challenges of Mandatory Life Cycle Assessments in the EU Space Act

Cecilia Nota (Università di Torino)

05/06/2026, 14:30

The proposed EU Space Act represents a landmark paradigm shift in space governance by importing the so-called Polluter Pays Principle (PPP) from Union environmental law into the regulatory framework of outer space activities. Central to this initiative is the transition from a reactive liability regime to a proactive model of environmental stewardship through mandatory Life Cycle Assessments...

31. A payload-aware LCA eco-design tool for iterative launch vehicle development

Marie Delaroche (MaiaSpace)

05/06/2026, 15:00

Integrating environmental considerations into launcher design presents unique challenges due to the iterative nature of development processes, limited production volumes, variety of design versions, and specialized materials involved. This study presents the development and application of an environmental trade-off tool designed to support eco-design for the MaiaSpace launch vehicle. The tool...

27. Towards integrated ecodesign of space launch systems: A digital LCA tool for early-stage decision-making

Enrique Moliner (Arribes Enlightenment)

05/06/2026, 15:15

The transition towards more sustainable space activities requires the integration of environmental considerations across all phases of design and operation, as well as the consideration of multiple impact dimensions beyond traditional performance metrics. In this context, this work presents a digital tool based on life cycle assessment (LCA) useful to support ecodesign in space launch systems,...

52. Satellite Brightness Model

Achraf Mizmizi (Politecnico di Milano)

05/06/2026, 15:30

Artificial light pollution in the night sky has increased significantly in recent years, raising growing concern among institutions and the space community. International bodies, including the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) and the International Astronomical Union (IAU), have recognized satellite brightness as a major sustainability challenge. Despite...

38. Is Active Debris Removal Beneficial? An Environmental Risk Analysis with THEMIS 1.0

Martina Rusconi (Politecnico di Milano)

05/06/2026, 15:45

In recent years, simulations based on evolutionary models of the space debris population, from many studies in the literature, have shown the need for more actions to mitigate the space debris problem, beyond post-mission disposal of satellites at the end of life. Many derelict objects have been left in orbit since the first space missions and more will inevitably be left in orbit in the...

53. Integrated Assessment of Satellite Optical Brightness for Preservation of Dark and Quiet Skies

Lorenzo Cimino (Sapienza University of Rome)

05/06/2026, 16:00

The concern raised by astronomers due to undesired acquisitions of space debris and satellites streaks in astronomical images determined a growing interest in so called Dark and Quiet Skies policies over the last years. Space agencies, international organizations and national governments are issuing new recommendations and laws aimed at ensuring
that the apparent brightness of space objects...

10. Storm-Time Geospace Variability and Orbital Sustainability: Why Space Weather Matters for Capacity Management

Nouhaila Bouhadi (Universtity Chouaïb Doukkali, Faculty of Sciences)

05/06/2026, 16:15

This contribution explores how geomagnetic storm conditions should be incorporated into discussions on space sustainability and orbital capacity management. While space capacity is often discussed through debris population, launch traffic, and mitigation compliance, disturbed space weather conditions also play a significant role by altering upper-atmospheric density, drag, orbital prediction,...
