We've learned about the first space exploration missions to Saturn, Pioneer 11 and Voyager 1 & 2.
On October 15 1997, we launched the Cassini-Huygens spacecraft.
After seven years it reached Saturn, and orbited the planet to take pictures of Saturn and it's moons like Titan.
We have learned a lot about Saturn from these pictures, including an interesting picture that showed a hexagon shape at the top of the planet.

In 2004, the Cassini part of the spacecraft launched the Huygens probe to land on the moon Titan.
It landed on Titan and sent back some information about the surface along with some great pictures of things we've never been able to see before.
