Reports sent from Cassini have indicated the potential to contain habitable, or prebiotic, environments on Enceladus and Titan, two of Saturn’s moons.
It first entered Saturn’s orbit June 30, 2004. After its initial four-year mission, Cassini was extended two more times. Its key discoveries were the ocean-bearing moon on Enceladus and the liquid methane seas on Titan.
