While Cassini is in Saturn's orbit, organisers hope it will take close up photos of the planet and it's rings.
But scientists have warned the craft will be flying too fast to take snaps of large areas.
It's also hoped Cassini will gather scientific data for about an hour while it is above Saturn's ring plane.
Long journey
The $3bn spacecraft's Saturn orbit will mark the end of Cassini's seven year journey across the solar system.
Highlights of the trip include Cassini's four gravity-assist fly-by manoeuvres to help carry it to the sixth planet from our Sun.
