Imagine a giant space rock coming close to Earth! Scientists are working hard to keep us safe from these space rocks, called asteroids.
They have a cool idea to use the asteroid's own dust like a rocket to push it away from Earth.
A special spaceship would collect the dust and blow it out like a giant dust cloud, changing the asteroid's path.
This is still a plan, but it might help us protect Earth and even find treasures on asteroids in the future!
