NASA outlined the conclusion in a new blog post on Wednesday, explaining that the “kinetic impactor” technique, which APL writer Ajai Raj jokingly defines as “smashing a thing into another thing,” could indeed be used as an effective means of planetary defense. “These findings add to our fundamental understanding of asteroids and build a foundation for how...
