NASA changed an asteroid's path around the sun. This new test helps us learn to stop bad space rocks.

This was the first time people changed a space rock's path. The asteroid was never a threat to our planet, Earth.

The changes to the asteroid's path were very small. But small changes can save Earth over many years.

The Dart spacecraft hit an asteroid called Dimorphos. This made Dimorphos travel around the sun a little faster.

Scientists will learn more from this special impact soon. Another spacecraft will visit these asteroids in November.
