NASA recently concluded its fifth biennial Planetary Defense Interagency Tabletop Exercise, aimed at assessing and improving the nation’s readiness to respond to potential asteroid or comet threats. Held in collaboration with FEMA and supported by the U.S. Department of State Office of Space Affairs, the exercise simulated a scenario involving a hypothetical asteroid impact threat.
Assessment and Scenario Details
The exercise, which took place at the Johns Hopkins Applied Physics Laboratory in Maryland, gathered nearly 100 representatives from various U.S. government agencies and international partners. Participants engaged in discussions and planning sessions centered around a scenario where a previously undetected asteroid had a 72% chance of colliding with Earth in approximately 14 years. Initial observations lacked crucial details about the asteroid’s size, composition, and trajectory, complicating response efforts. Moreover, delays in follow-up observations due to the asteroid’s position behind the Sun heightened the scenario’s urgency.
NASA’s Lindley Johnson emphasized the exercise’s value in preparing for such unprecedented events, noting, “A large asteroid impact is potentially the only natural disaster humanity has the technology to predict years in advance and take action to prevent.”
Technological Advancements and Preparedness
The tabletop exercise also marked the integration of insights from NASA’s DART (Double Asteroid Redirection Test) mission, which demonstrated the viability of kinetic impactors to deflect asteroids. The mission’s success in altering the trajectory of the asteroid Moonlet Dimorphos underscored the potential effectiveness of such technologies in mitigating impact risks. However, implementing these technologies in response to a real-world threat requires extensive planning and international collaboration.
To bolster preparedness efforts, NASA continues to develop the NEO Surveyor (Near-Earth Object Surveyor), an infrared space telescope scheduled for launch in June 2028. NEO Surveyor aims to enhance the detection and characterization of potentially hazardous near-Earth objects well in advance of any potential impact threat.

Future Directions and Recommendations
Following the exercise, NASA plans to release a comprehensive after-action report detailing strengths, gaps, and recommendations identified during the discussions and simulations. These insights will inform future exercises and studies, ensuring ongoing improvements in planetary defense preparedness across NASA and partner agencies.
Lindley Johnson emphasized the importance of these outcomes, stating, “These findings will shape our future strategies and exercises to enhance our collective ability to respond to planetary defense challenges.”
Since its establishment in 2016, NASA’s Planetary Defense Coordination Office has been at the forefront of coordinating national and international efforts to safeguard against potential asteroid threats. The collaboration between NASA, FEMA, and other stakeholders underscores a commitment to proactive disaster preparedness and response, aiming to mitigate risks and protect global communities from potential catastrophic events originating in space.
