NASA's Cassini Mission Grand Finale at Saturn --Join Live At NASA's Jet Propulsion Lab (Today's 'Galaxy' Stream)
During its journey, Cassini has made many discoveries, including a global ocean with hydrothermal activity within Saturn's moon Enceladus, and vast seas of liquid methane on the planet's largest moon, Titan. Cassini began the final, dramatic phase of its mission, called the Grand Finale, on April 26, with the first of planned 22 dives between Saturn and its rings. The finale orbits bring the spacecraft closer to Saturn than ever before, providing stunning, high-resolution images and new insights into the planet's interior structure and the origins of the rings. During its final plunge into Saturn, Cassini will send data about the atmosphere's composition until its signal is lost.
