NASA has successfully tested its ability to deflect an asteroid from its course around the Sun. In a 2022 experiment, a spacecraft crashed into a small asteroid called Dimorphos, pushing it into a new orbit. Researchers tracked the asteroid’s movement and found that it had changed by just 0.15 seconds – a tiny change that can add up over time. The test shows promise for defending Earth against future asteroid threats, making it a significant step forward in planetary defense efforts.
