9th IAA PLANETARY DEFENSE CONFERENCE 2025

Overview: IAA Planetary Defense Conference 2025 - Stellenbosch, Cape Town, South Africa

Conference Dates: 5-9 May 2025

The International Academy of Astronautics (IAA) Planetary Defense Conference 2025 in Stellenbosch, Cape Town, South Africa, brings together leading experts, researchers, policymakers, and stakeholders from around the world to discuss and advance the global effort in planetary defense. The conference aims to address the growing need for coordinated international strategies to detect, monitor, and mitigate potential threats posed by Near-Earth Objects (NEOs).

Ongoing and Upcoming Mission Highlights

The conference will spotlight current and proposed space missions that are instrumental in developing and testing planetary defense technologies. Key missions under discussion include:

• Hera: The European Space Agency's mission to the binary asteroid system Didymos, focusing on deflection technology.
• Hayabusa2#: Japan’s mission targeting sample return and study of asteroid Ryugu.
• OSIRIS-REx/APEX: NASA's mission that successfully collected samples from asteroid Bennu.
• NEO Surveyor: NASA’s proposed mission aimed at discovering hazardous NEOs.
• Apophis: Discussions on the upcoming close approach of this significant asteroid.

These missions are critical in enhancing our understanding and preparedness for planetary defense.

Hypothetical Asteroid Threat Exercise

A major component of the conference will be a hypothetical asteroid threat exercise, which will provide a platform for discussing policy planning and the development of an international planetary defense strategy. Topics will include:

• Current national and international activities, strategies, and plans for planetary defense.
• Proposals for designating 2029 as the International Year of Asteroid Awareness and Planetary Defense, coinciding with the close approach of asteroid Apophis. This segment will explore ideas for a global awareness campaign.

Near-Earth Object (NEO) Discovery

This session will cover the latest advancements in NEO discovery efforts, focusing on:

• The progress, requirements, and goals of current and future NEO survey systems.
• Techniques for discovering NEOs through both ground-based and space-based observatories.
• Future survey systems, such as the Large Synoptic Survey Telescope (LSST) and the NEO Surveyor, which aim to improve detection capabilities.

Near-Earth Object (NEO) Characterization

This section will delve into the characterization of NEOs, which is vital for effective planetary defense. Topics will include:

• Physical, dynamical, and orbital properties of NEOs, with an emphasis on their relevance to defense missions.
• Technologies used for remote sensing and spacecraft missions aimed at characterizing NEOs.
• Opportunities presented by NEOs that come in close proximity to Earth, offering real-time research possibilities.

Deflection/Disruption Modeling & Testing

Participants will discuss the latest in modeling and experimentation regarding NEO deflection and disruption, which are key to mitigating potential threats. The focus will be on:

• Experimental results that assess the effectiveness of various deflection and disruption techniques.
• Progress in developing technologies crucial for the mitigation of hazardous NEOs.

Space Mission & Campaign Design

This session will highlight the development of critical technologies and mission designs essential for planetary defense, including:

• Flight validation missions aimed at testing defense strategies.
• Concepts for rapid response reconnaissance missions.
• Strategies for in-space campaigns to address hazardous NEOs through reconnaissance, characterization, and mitigation.

Earth Impact Effects & Consequences

An in-depth analysis of the potential impacts of NEOs on Earth, considering:

• Hazards posed by individual impactors and the cumulative risk from the predicted population of impactors.
• Tools to aid decision-makers in understanding impact scenarios.
• The atmospheric breakup process, airbursts, and the transition from regional to global effects.
• New findings on the impact effects on both land and ocean, including environmental and atmospheric consequences.

Disaster Management & Impact Response

Drawing from past natural disasters, this session will explore:

• Lessons learned and their application to planetary defense.
• Review of current and upcoming disaster response plans specific to NEO impacts.
• Strategies for effective communication with the public and decision-makers during such events.

Public Education and Communication

The importance of public education and communication in planetary defense will be underscored, with discussions on:

• The current status and effectiveness of public education efforts related to NEOs.
• Concepts for improving public trust and engagement in planetary defense initiatives.

The Decision to Act: Political, Legal, Social, and Economic Aspects

The conference will address the broader implications of planetary defense, including:

• Outlook on current and future national and international planetary defense / NEO-response policies and
  decision-making processes, including any envisioned participation of nations’ defense sector in
  planetary defense.
• International coordination and collaboration, and distribution of responsibilities for planetary defense.
• Legal aspects of NEO mitigation.
• Cost effectiveness of mitigation options.
• Short and long term economic, political, and social consequences of a serious threat or an impact
• Ethics of Planetary Defense.

Public Education and Communication

The importance of public education and communication in planetary defense will be underscored, with discussions on:

• The current status and effectiveness of public education efforts related to NEOs.
• Concepts for improving public trust and engagement in planetary defense initiatives.

The IAA Planetary Defense Conference 2025 promises to be a comprehensive forum for advancing our collective knowledge, strategies, and readiness to face potential asteroid threats, with a focus on fostering international cooperation and public awareness.
