Summary: Scientists at Los Alamos National Laboratory, a United States Department of Energy facility in New Mexico, used a supercomputer to model nukes'. They attacked a 1,650-foot-long space rock with a 1-megaton nuclear weapon. "Ultimately this 1-megaton blast will disrupt all of the rocks in the rockpile of this asteroid, and if this were an Earth-crossing asteroid, would fully mitigate the hazard represented by the initial asteroid itself," Los Alamos scientist Bob Weaver said.

Critique: I think it would be cool to be able to destroy an asteroid with a nuclear bomb.

Impact: this is a positive thing because we would be able to destroy an asteroid if we were in danger.
