A6. 24th IAA SYMPOSIUM ON SPACE DEBRIS
The Symposium will address the complete spectrum of issues associated to space debris, including orbital sustainability and operations in debris dominated environment. It will cover every aspect of Space Environment Management (SEM) including Mitigation and Remediation measures, Space Surveillance and Tracking (SST), Space Situational Awareness (SSA), Space Traffic Management (STM), including all aspects of measurements, modelling, risk assessment in space and on the ground, re-entry, hypervelocity impacts and protection, mitigation and standards, post-mission disposal, remediation, debris removal, Space Surveillance, collision avoidance as well as non-technical topics associated to space debris dominated environment such as space ethics.

A6.1. Space Debris Measurements and Orbit Determination SST (1)
This session will address all aspects related to the measurement of space objects and orbit determination. It will cover both ground-based and space-based techniques, as well as methods for identification and characterization of objects. Special attention will be given to data processing, orbit accuracy, and strategies to improve coverage and reliability of surveillance and tracking networks.

A6.2. Resident Space Objects Characterisation and High Velocity Impacts
This session will focus on the detailed characterization of resident space objects (RSO), including small debris and angular motion determination through estimation, simulation, and experimentation. It will also explore phenomena associated with high-velocity impacts, protection and shielding tests, and fragmentation simulations, with the objective of evaluating risks and effects on operational spacecraft.

A6.3. Environment Modelling and Risk Assessment
This session will cover the modelling of the space debris environment and the assessment of associated risks. Topics will include collision risk analyses, estimations based on population models and deterministic catalogues, as well as studies on the reconstruction of break-up and fragmentation events. The session will also address validation of models through observations and laboratory experiments, aiming to improve the prediction of orbital environment evolution. It will also examine methods for assessing orbital capacity and congestion, including indicators for orbital slot usage, and impact of allocation strategies on population dynamics. The combined perspective of environmental modelling and capacity management provides a comprehensive view of the long-term sustainability of the orbital environment.

A6.4. Operations in Congested Space: Situational Awareness and Space Traffic Management – SSA
This session will examine operations within the framework of Space Situational Awareness (SSA) and Space Traffic Management (STM). It will address strategies and systems for enhancing satellite operational safety, artificial intelligence applications in SSA, collision avoidance manoeuvres, and coordination of operations in large LEO constellations (LLC). Emphasis will be placed on data integration and international cooperation to ensure the safe management of the orbital environment.

A6.5. Post Mission Disposal and Space Debris Removal – SEM
This session will focus on space debris mitigation and remediation strategies, including Post-Mission Disposal (PMD) and Active Debris Removal (ADR) techniques and technologies (both ground and space-based). A particular focus will be given to in-orbit demonstration missions, ADR mission design and analysis, and rendezvous and proximity operations incorporating GNC and robotics aspects. The goal is to assess the feasibility, safety, and efficiency of these solutions to reduce on-orbit risks.

A6.6. Orbit Propagation and Mitigation Assessment
This session will address the study of orbital dynamics of space objects, the development of propagation techniques, and long-term environment simulations, including aspects related with space ethics. It will assess the effectiveness of various mitigation measures and evaluate the impacts of different population evolution scenarios. Outcomes will support the definition of guidelines for sustainable management of Earth orbits.

A6.7. Re-entry Modelling and Interaction with Atmosphere
This session will discuss atmospheric re-entry modelling and its interaction with the atmosphere. It will cover prediction and safety aspects, analysis of atmospheric break-up processes (both mechanical and thermal), and experimental testing. The session will also consider the environmental impact of re-entry, including pollution and potential effects on aviation safety. Advances in models and prediction tools will be presented.

A6.8-E9.1. Policy, Legal, Institutional, Economic and Security Aspects of Debris Mitigation, Debris Remediation and STM
This session will address all non-technical aspects of debris mitigation, debris remediation and STM. Papers may focus on aspects of responsibility, liability and registration, on the role of bodies such as UNCOPUOS or IADC, as well as on insurance, financial incentives and funding. In addition, security-related aspects and the role of international cooperation in addressing these issues may be considered.

A6.IP. Interactive Presentations - 24th IAA SYMPOSIUM ON SPACE DEBRIS
This session offers a unique opportunity to deliver your key messages in an interactive presentation on any of the subjects of Space Debris addressed in the classic Sessions. The presentation will be displayed on a digital screen in a dedicated location and available for view by all Congress attendees for the entire Congress week. In addition, one afternoon is dedicated exclusively for the attendees to view the Interactive Presentations, and the author will be assigned a specific ten minute slot to personally present the topic and interact with the attendees present. The Interactive Presentation may take advantage of all electronic display capabilities, such as: PowerPoint charts, embedded hot links, pictures, audio and video clips etc. An award will also be presented to the author of the best Interactive Presentation in the A Category at a special ceremony. An Abstract that follows the standard format must be submitted by the deadline for standard IAC abstracts.
