Detection & Assessment: If an asteroid with a potential impact threat is found, it is reported to the Minor Planet Center, and follow-up observations refine its orbit and impact probability. NASA’s Center for NEO Studies and ESA’s NEO Coordination Centre handle impact probability calculations.
International Response: The International Asteroid Warning Network (IAWN) would issue alerts and coordinate notifications through the UN. Space agencies like NASA and ESA would inform their respective governments and emergency response agencies.
Mitigation & Deflection Planning: The Space Mission Planning Advisory Group (SMPAG) would assess response options, such as reconnaissance or deflection missions. A recommendation would be developed for decision-makers.
Preparedness Efforts: Even without an immediate threat, IAWN and SMPAG conduct regular meetings, asteroid observations, and impact response exercises with agencies like NASA, ESA, and FEMA. They test asteroid tracking, alert procedures, and response planning.
Deflection Strategies: Possible asteroid deflection methods include nuclear detonations (politically sensitive), ion-beam shepherds (not yet demonstrated), and kinetic impactors (e.g., NASA’s DART mission, tested in 2022).
Upcoming Events: The close flyby of asteroid Apophis in 2029 will provide a research opportunity. NASA’s OSIRIS-APEX mission will study Apophis post-flyby.
