Artists's Conception of Cassini Saturn Orbit Insertion.
The Cassini spacecraft was launched on October 15, 1997 on a seven-year journey to investigate Saturn, its rings, and its moons. The spacecraft consists of an orbiter and the European Space Agency's Huygens Titan probe. Cassini arrived at the planet in 2004 and continues to study the Saturn system with 12 different instruments.
The Huygens probe was deployed from the Cassini spacecraft and landed on the moon Titan in January of 2005. The probe entered the clouds of Titan and gathered atmospheric data and images as it parachuted to the surface. It collected surface data for a little over an hour, which was longer than expected.
