For more great images from Cassini and the Huygens probe, see "Our Saturn years", the story of the mission as told by the people who worked on it.

During its seven-year journey, Cassini would carry out several “slingshot” manoeuvres, using the gravity of Venus and Jupiter to alter its path and speed. This allowed the spacecraft to save propellant and time on its way to Saturn.
