Voyager 1 is a small spacecraft.
A spacecraft is a machine for space.
It left Earth many years ago.
Today, it is still working far away.
It sends science information home.
It is the farthest machine made by people. (jpl.nasa.gov)
It also carries a special gold record.
The record has sounds, music, pictures, and greetings.
These things say, “Hello. This is our home.”
Maybe no one will ever find it.
But the message keeps moving through space. (science.nasa.gov)
Think of a bottle in the sea.
You put a letter inside it.
Then the water carries it far away.
Voyager 1 is like that bottle.
Its sea is the dark space between stars.
