Stopping deadly asteroids with a DART

December 21, 2021

Space may be largely empty, but catastrophic collisions are inevitable.

One day, a major asteroid will be headed straight for Earth, begging the question: What can we do to stop it?

Scientists are seeking to answer that question with DART, or the Double Asteroid Redirection Test.

The probe will head to a binary system Didymos, where it will smash straight into the smaller object in something called a kinetic impact deflection.

The force won't fling the asteroid far but it will change its orbital path, giving scientists better insight into what it might take to steer a future asteroid off of a collision course with Earth.
