Defending The Earth Against Asteroids Will Be Hard With Our Limited Technology

The world will have to live with surprise asteroid attacks on the scale of Friday’s Russian fireball, at least for a while. Asteroids of this size are both difficult to detect and incredibly numerous, so it will take a long time for astronomers to find and map out the orbits of all the potentially dangerous ones. Besides, researchers have bigger fish to fry.”Defending the Earth against tiny asteroids such as the one that passed over Siberia and impacted there is a challenging issue that is something that is not currently our goal,” Paul Chodas, a scientist with the Near Earth Object Program Office at NASA’s Jet Propulsion Laboratory in Pasadena, Calif., told reporters Friday (Feb. 15).

Chodas added also we have limited defense techology at the current time especially after a level 4 attack.
