What music would you want them to hear, and what sights would you want them to see?

The "Voyager" spacecraft were designed to visit the outer planets in our solar system.

Both spacecraft visited Jupiter and Saturn, and "Voyager 2" visited four planets-- Jupiter, Saturn, Uranus, and Neptune-- in something we call the "Grand Tour."

Hi, I'’m astronomer Amy Mainzer.

When scientists and engineers were building the "Voyager" spacecraft, they knew that these spacecraft would travel a huge, long distance out into deep space.

And they thought that, maybe someday, well, maybe somebody would find them, and if they did, what would they want them to know about us?

With that in mind, they designed these golden records.

Golden records carry greetings from people in dozens of different languages.

- Konnichiwa.

- Hola, y saludos a todos.

- [woman speaking native language] - The outside covers have a lot of scientific information about Earth.

They even carry our galactic address, how to find us.

The "Voyager" missions are traveling incredibly fast, but space is incredibly big.

So it'’ll take tens of thousands of years until these spacecraft reach even the nearest stars.

Maybe it'’ll be millions of years or maybe never until an alien species finds them.

But if they do, they'’ll have these golden records that'’ll tell them a little bit about us.

So the next time you'’re listening to your favorite record or reading your favorite book, think about what you'’d put on your own golden record that you would send out to the stars.
