  In October 1997 was the Cassini's first launch. This is the first step in the spacecraft's mission, ''the Enceladus mission.''

  Welcome to Venus, first site of Cassini's path. The ship traveled 176 miles. Cassini later orbited Venus again.
 - 
  
  Cassini is orbiting Venus for the second time. Did they go backwards?
 - 
  
  Here is Cassini's greatest planet it orbited-Earth. the journey was 727 miles. It was just one step closer to finishing the mission and returning home.

  Now we come to Jupiter, Cassini's final stop before Saturn. We're almost there.
 - 
  
  On this day, Cassini started orbiting Saturn where it begins to study the planet and its rings. Cassini is the first spacecraft to travel to the outer planets.
 - 
  
  Cassini now reaches its next stop, Titan, one of Saturn's moons. This way we can gather more information about the planet.
 - 
  
  It was on this day that Cassini dove through the Enceladus (another one of Saturn's moons) plume. What a dangerous journey!
 - 
  
  Sadly, Cassini's extended mission (it was originally planned for four years) ended in June, 2008. But this isn't the end for Cassini.
 - 
  
  Cassini was chosen for the latest mission, ''the solstice mission.'' This journey should end in September 2017.
