How realistic is NASA’s planetary defense test of asteroid deflection?

On September 26, NASA will crash a spacecraft into an asteroid to disrupt its path. The space rock is not predicted to collide with Earth, nor is another known asteroid or large object. The impact is a test – the core of NASA’s Double Asteroid Redirection Test (DART) mission. While there’s no real impending collision, the DART mission closely mimics what NASA scientists would do if an asteroid was headed for Earth. The mission will also provide scientists with valuable data that will better prepare them for diverting a large asteroid or comet if anyone would come to us.

“It’s exactly the kind of mission we would use to actually deflect an asteroid,” Seth Jacobson, an assistant professor of planetary sciences at Michigan State University and a co-investigator on the mission, told .
