NASA's Mission to Protect Earth from Asteroids


NASA is committed to safeguarding our planet from the potential threat of asteroid impacts through proactive detection, monitoring, and mitigation efforts.

Asteroid Detection

NASA's Near-Earth Object (NEO) program identifies and tracks asteroids that could pose a risk to Earth, utilizing ground-based telescopes and space-based observatories.

Risk Assessment

NASA assesses the impact risk posed by near-Earth asteroids, calculating the probability of potential collisions and determining the potential consequences of an impact.

Defense Strategies

NASA develops and tests various planetary defense strategies to mitigate the threat of asteroid impacts, including deflection techniques such as kinetic impactors.


NASA collaborates with international partners, space agencies, and organizations to enhance asteroid detection and mitigation efforts, fostering global cooperation.

Asteroid Redirect

NASA explores the possibility of redirecting hazardous asteroids away from Earth's path through innovative missions, such as the Asteroid Redirect Mission (ARM).


NASA conducts impact modeling and simulation exercises to better understand the potential effects of asteroid impacts on Earth's surface and to inform disaster response.

Public Awareness

NASA engages the public through outreach and education initiatives to raise awareness about the threat of asteroid impacts and the importance of planetary defense efforts.


Through its mission to protect Earth from asteroids, NASA demonstrates its commitment to ensuring the safety and security of our planet.
