Behind the Scenes: Who Coordinates Planetary Protection?
Understanding the System: Agencies, Missions, and Mandates
If you’re curious about the science, policy, and partnerships behind asteroid detection and planetary defense, it can be hard to know where to begin. This isn’t just one agency’s responsibility, or one nation’s job. It’s an interconnected effort that spans astronomy, aerospace engineering, emergency management, international diplomacy, and risk communication.
Below is a curated list of reliable, up-to-date resources to help you dive deeper into the world of planetary defense. Whether you’re a student, policymaker, space enthusiast, or emergency planner, this is your launchpad to understanding what’s being done, and what’s still needed.
Core Agencies and Programs working towards Planetary Defense
NASA Planetary Defense Coordination Office (PDCO)
The hub of NASA’s planetary defense strategy. Offers updates on near-Earth object tracking, impact risk assessments, and mission updates.European Space Agency – Planetary Defense Division
ESA’s planetary defense efforts, including their work on the Hera mission and international partnerships.International Asteroid Warning Network (IAWN)
A global coordination body of observatories and space agencies that monitor and share asteroid tracking data.Space Mission Planning Advisory Group (SMPAG)
An international advisory body focused on planning and recommending collaborative space missions to mitigate potential threats.United Nations Office for Outer Space Affairs (UNOOSA)
UNOOSA plays a coordinating role in international discussions on space hazards and supports IAWN and SMPAG activities.
