DART, or the Double Asteroid Redirection Test, is a NASA mission designed to test a method of planetary defense against potential asteroid threats. Launched in November 2021, DART aims to change the trajectory of a small asteroid named Dimorphos by crashing a spacecraft into it. This impact will help scientists understand how to redirect asteroids that could pose a risk to Earth. The mission is part of a broader effort to develop strategies for protecting our planet from hazardous asteroids. By studying the results of the impact, researchers hope to gather valuable data on the effectiveness of kinetic impactor techniques, which could be crucial for future planetary defense initiatives.
