A rocket went to space last year. It did a big job. It helped send two small ships to the moon. But one part was left behind. Now that old part is still flying!

The rocket part is very big. It is as tall as a building! It has no fuel left. The moon is pulling it closer. It will hit the moon very fast. It will make a big hole!

Scientists want to watch it happen. They will use big telescopes. They hope to see a dust cloud. It is very exciting for everyone. Space is full of surprises!
