saturn Shadows and Rings

Preston Dyches, NASA Jet Propulsion Laboratory and Seth Shostak, SETI Institute Compared to the age of the solar system -- about four-and-a-half billion years -- a couple of decades are next to nothing. Some planetary locales change little over many millions of years, so for scientists who study the planets, any object that evolves on such a short interval makes for a tempting target for study. And so it is with the ever-changing rings of Saturn. Case in point: Saturn's narrow, chaotic...

Titan subsurface reservoirs

European Space Agency The international Cassini mission has revealed hundreds of lakes and seas spread across the icy surface of Saturn's moon Titan, mostly in its polar regions. These lakes are filled not with water but with hydrocarbons, a form of organic compound that is also found naturally on Earth and includes methane. While most of the liquid in the lakes is thought to be replenished by rainfall from clouds in the moon's atmosphere, the cycling of liquid throughout Titan's crust and...

renewed cloud activity on titan

Preston Dyches, NASA Jet Propulsion Laboratory NASA's Cassini spacecraft recently captured images of clouds moving across the northern hydrocarbon seas of Saturn's moon Titan. This renewed weather activity, considered overdue by researchers, could finally signal the onset of summer storms that atmospheric models have long predicted. A movie showing the clouds' movement is available at: http://www.jpl.nasa.gov/spaceimages/details.php?id=PIA18420 The Cassini spacecraft obtained the new...

Preston Dyches, NASA Jet Propulsion Laboratory NASA's Cassini spacecraft will execute the largest planned maneuver of the spacecraft's remaining mission on Saturday, Aug. 9. The maneuver will target Cassini toward an Aug. 21 encounter with Saturn's largest moon, Titan. The main engine firing will last about a minute and will provide a change in velocity of 41 feet per second (12.5 meters per second). This is the largest maneuver by Cassini in five years. No other remaining maneuver...

Enceladus South Pole

Preston Dyches/Dwayne Brown/Steve Mullins, NASA Scientists using mission data from NASA's Cassini spacecraft have identified 101 distinct geysers erupting on Saturn's icy moon Enceladus. Their analysis suggests it is possible for liquid water to reach from the moon's underground sea all the way to its surface. These findings, and clues to what powers the geyser eruptions, are presented in two articles published in the current online edition of the Astronomical Journal. Over a period...

Moscow Institute of Physics and Technology (MIPT) A researcher from MIPT, Prof. Vladimir Krasnopolsky, who heads the Laboratory of High Resolution Infrared Spectroscopy of Planetary Atmospheres, has published the results of the comparison of his model of Titan’s atmosphere with the latest data. The article in the journal Icarus compares the chemical composition of Titan’s atmosphere with parameters predicted by a mathematical model. The atmosphere of Saturn’s largest moon was...

Ocean On Saturnian Moon Titan May Be As Salty As The Dead Sea

Gerard LeBlond for redOrbit.com - Your Universe Online The inner ocean of Saturn’s largest moon Titan may be as salty as the Dead Sea, according to scientists with NASA’s Cassini mission, which has been collecting gravity and topographic data from the distant Saturnian satellite over the last ten years. After studying the data, researchers built a model structure of Titan, resulting in a better understanding of the moon’s outer ice shell. The study was published this week in the...

WASHINGTON, July 2, 2014 /PRNewswire-USNewswire/ -- Scientists analyzing data from NASA's Cassini mission have firm evidence the ocean inside Saturn's largest moon, Titan, might be as salty as the Earth's Dead Sea. http://photos.prnewswire.com/prnvar/20081007/38461LOGO The new results come from a study of gravity and topography data collected during Cassini's repeated flybys of Titan during the past 10 years. Using the Cassini data, researchers presented a model structure for Titan,...

cassini grand finale

Preston Dyches, NASA Jet Propulsion Laboratory With input from more than 2,000 members of the public, team members on NASA's Cassini mission to Saturn have chosen a name for the final phase of the mission: the Cassini Grand Finale. Starting in late 2016, the Cassini spacecraft will begin a daring set of orbits that is, in some ways, like a whole new mission. The spacecraft will repeatedly climb high above Saturn's north pole, flying just outside its narrow F ring. Cassini will probe the...

redOrbit Staff & Wire Reports - Your Universe Online [ Watch the Video: Cassini Saturn Arrival ] Monday, June 30 marks the 10th anniversary of the Cassini spacecraft’s arrival in the Saturn system, beginning a four-year primary mission that was extended on three occasions and ultimately led to the collection of more than 500 GB of data and the publication of well over 3,000 scientific papers. Cassini reached its destination on June 30, 2004, carrying with it the European Space...

Cassini-Huygens Mission -- The Cassini unmanned space probe is intended to study Saturn and its moons. It was launched on October 15, 1997 and is estimated to enter Saturn's orbit on July 1, 2004. The mission is a joined NASA/ESA project. Cassini's principal objectives are to: -- determine the three-dimensional structure and dynamical behavior of the rings -- determine the composition of the satellite surfaces and the geological history of each object -- determine the nature and...

Saturn's moon Titan -- Titan is the planet Saturn's largest moon. It is larger than either of the planets Mercury or Pluto and is the second-largest moon in the solar system after Ganymede (it was originally thought to be slightly larger than Ganymede, but recent observations have shown that its thick atmosphere caused overestimation of its diameter). Titan was discovered on March 25, 1655 by the Dutch astronomer Christian Huygens, making it one of the first non-terrestrial moons to be...

The Planet Saturn -- in astronomy, 6th planet from the sun. Astronomical and Physical Characteristics of Saturn Saturn's orbit lies between those of Jupiter and Uranus; its mean distance from the sun is c.886 million mi (1.43 billion km), almost twice that of Jupiter, and its period of revolution is about 291/2 years. Saturn appears in the sky as a yellow, starlike object of the first magnitude. When viewed through a telescope, it is seen as a golden sphere, crossed by a series of...
