- **NASA and International Coordination**: NASA's Planetary Defense Office and international bodies like the International Asteroid Warning Network (IAWN) and the Space Mission Planning Advisory Group (SMPAG) play critical roles in assessing asteroid threats and coordinating responses[1][2].
- **Risk Assessment and Notification**: Specific protocols are in place for assessing the risk of NEO impacts, including detailed procedures for notification and potential mitigation missions as outlined in the Near-Earth Object Impact Threat Emergency Protocols (NITEP) report[2].
- **Thresholds for Action**: The decision to undertake reconnaissance, deflection, or disruption missions depends on the risk assessment, including the probability of impact, potential damage, and feasibility of mitigation measures[2].
