    Cassini Beams Back First Images from New Orbit

    NASA's Cassini spacecraft has sent to Earth its first views of Saturn's atmosphere since beginning the latest phase of its mission. The new images show scenes from high above Saturn's northern hemisphere, including the planet's intriguing hexagon-shaped jet stream.

    Cassini began its new mission phase, called its Ring-Grazing Orbits, on
    Nov. 30. Each of these weeklong orbits -- 20 in all -- carries the spacecraft high above Saturn's northern hemisphere before sending it skimming past
    the outer edges of the planet's main rings.

    Cassini's imaging cameras acquired these latest views on Dec. 2 and 3,
    about two days before the first ring-grazing approach to the planet. Future passes will include images from near closest approach, including some
    of the closest-ever views of the outer rings and small moons that orbit
    there.

    "This is it, the beginning of the end of our historic exploration of Saturn. Let these images -- and those to come -- remind you that we've lived a
    bold and daring adventure around the solar system's most magnificent planet," said Carolyn Porco, Cassini imaging team lead at Space Science Institute, Boulder, Colorado.

    The next pass by the rings' outer edges is planned for Dec. 11. The ring-grazing
    orbits will continue until April 22, when the last close flyby of Saturn's moon Titan will once again reshape Cassini's flight path. With that encounter, Cassini will begin its Grand Finale, leaping over the rings and making
    the first of 22 plunges through the 1,500-mile-wide (2,400-kilometer)
    gap between Saturn and its innermost ring on April 26.

    On Sept. 15, the mission's planned conclusion will be a final dive into Saturn's atmosphere. During its plunge, Cassini will transmit data about
    the atmosphere's composition until its signal is lost.

    Launched in 1997, Cassini has been touring the Saturn system since arriving
    in 2004 for an up-close study of the planet, its rings and moons. Cassini
    has made numerous dramatic discoveries, including a global ocean with indications of hydrothermal activity within the moon Enceladus, and liquid methane seas on another moon, Titan.

    The Cassini-Huygens mission is a cooperative project of NASA, ESA (European Space Agency) and the Italian Space Agency. NASA's Jet Propulsion Laboratory, a division of Caltech in Pasadena, manages the mission for NASA's Science Mission Directorate, Washington. JPL designed, developed and assembled
    the Cassini orbiter.
