Arrival at Saturn
On Jan. 22, 2012, the Sun erupted with a solar flare, a coronal mass ejection, and a burst of highly energetic protons known as solar energetic particles.
Team members reflect on what has made the NASA/ESA Cassini mission such an epic journey—the extraordinary spacecraft, tremendous science and historic international collaboration.

On Earth, the ocean floor is home to hydrothermal vents that spout hot water, nourishing life in an otherwise inhospitable environment. Scientists think similar vents could exist on other worlds.
