What was the main objective of the Cassini mission?

The main objective of the Cassini mission was indeed to study Saturn's rings and atmosphere. Launched in 1997, the Cassini spacecraft entered orbit around Saturn in 2004 and provided unprecedented data about the planet, its complex ring system, and its numerous moons.

Cassini's extensive range of instruments allowed scientists to analyze the composition of Saturn's atmosphere, including its weather patterns, and explore the intricate structure and dynamics of its rings. One of the mission's significant accomplishments was the discovery of new moons and insights into the potential habitability of some of Saturn's moons, such as Enceladus, which has subsurface oceans. By focusing on Saturn's rings and atmosphere, the mission greatly enhanced our understanding of not only Saturn but also the processes that govern planetary atmospheres and ring systems in general.
