A new report calls on NASA to establish a Planetary Defense Coordination Office to lead national and international efforts in protecting Earth against impacts by asteroids and comets .

The final report of the Ad-Hoc Task Force on Planetary Defense of the NASA Advisory Council was delivered to the Council this month, proposing five recommendations that suggest how the space agency should organize, acquire, investigate, prepare, and lead national and international efforts in planetary defense against near-Earth objects .

"This was a very important step in the process of the United States Government defining its role in protection of life from this occasional, but devastating natural hazard," former astronaut Russell Schweickart told SPACE.com. "Happily, in the instance of asteroid impacts, this is a natural disaster which can be prevented...only, however, if we properly prepare and work together with other nations around the world."
