NASA's Cassini spacecraft has captured never-before-seen views of Saturn from perspectives high above and below the planet's rings. Over the last several months, the spacecraft has climbed to higher and higher inclinations, providing its cameras with glimpses of the planet and rings that have scientists gushing. "Finally, here are the views that we've waited years for," said Dr. Carolyn Porco, Cassini imaging team leader at the Space Science Institute in Boulder, Colo. "Sailing high above...

JPL -- Scientists are celebrating the first Cassini spacecraft sighting of spokes, the ghostly radial markings discovered in Saturn's rings by NASA's Voyager spacecraft 25 years ago. A sequence of images taken on the side of the rings not illuminated by the sun has captured a few faint, narrow spokes in the outer B ring, about 3,500 kilometers long and about 100 kilometers wide (2,200 miles by 60 miles). Previously, scientists believed the visibility of spokes depended on the elevation of...

JPL -- In a spectacular kick-off to its first season of prime ring viewing, which began last month, the Cassini spacecraft has confirmed earlier suspicions of an unseen moon hidden in a gap in Saturn's outer A ring. A new image and movie show the new moon and the waves it raises in the surrounding ring material. The moon, provisionally named S/2005 S1, was first seen in a time-lapse sequence of images taken on May 1, 2005, as Cassini began its climb to higher inclinations in orbit around...

With the latest Titan images showing channels and fluid-like branching, scientists have begun the debate anew whether fluid might have shaped the Earth-like moon. Imaging science team leader for Cassini, Carolyn Porco, describes the initial surprise and excitement of seeing Titan up close. Astrobiology Magazine -- Carolyn Porco of the Space Science Institute (Boulder, Colorado) heads Cassini's imaging science team. She sat down with Astrobiology Magazine's Chief Editor, Helen Matsos, to give...
