JPL -- Cassini's second close flyby of Titan completes a 'before' and 'after' look at the fuzzy moon and provides the first direct evidence of changing weather patterns in the skies over Titan. In images obtained less than two months ago, the Titan skies were cloud free, except for a patch of clouds observed over the moon's south pole. In images taken Monday, Dec. 13, during Cassini's second close flyby of Titan, several extensive patches of clouds have formed. "We see for the first time...

Boulder -- Ice particles are key players in the ever-changing panorama at Saturn, according to a new study led by a University of Colorado at Boulder professor using an instrument on the Cassini-Huygens spacecraft now at the ringed planet. Larry Esposito of the Laboratory for Atmospheric and Space Physics said data from the Ultraviolet Imaging Spectrometer, or UVIS, indicates much of Saturn's system is filled with ice, as well as atoms derived from water. Esposito is the principal...

Iowa -- As NASA's Cassini spacecraft approached Saturn last July, it found evidence that lightning on Saturn is roughly one million times stronger than lightning on Earth. That's just one of several Cassini findings that University of Iowa Space Physicist Don Gurnett will present in a paper to be published Thursday, Dec. 16 in Science Express, an online version of the journal Science, and in a talk to be delivered Friday, Dec. 17 at a meeting of the American Geophysical Union in San...

The probe orbiting Saturn is not the only eye on Titan, the ringed planet's largest moon. Powerful ground telescopes have glimpsed storms travelling around the moon's mid-latitudes, not just near the south pole. One theory of how these storms arise relies on icy volcanoes beneath the thick haze and clouds. AM/Gemini-- Astronomers had seen storms around Titan's south pole before, but now they've been discovered at the moon's mid-latitudes as well. The discovery was made using the Gemini North...

JPL -- The Cassini spacecraft completed a successful rendezvous with Saturn's moon Titan today. This was the last pass before the European Space Agency's Huygens probe is sprung loose from Cassini on Christmas Eve. Information gathered during this flyby will provide an opportunity to compare images from Cassini's first close Titan encounter on Oct. 26. NASA's Deep Space Network tracking station in Madrid, Spain, acquired a signal at about 4:00 p.m. Pacific Standard Time (7:00 p.m. Eastern...

Astrobiology Magazine -- When Cassini flew by Saturn's moon Titan on October 26, scientists got a small taste of the discoveries to come. Athena Coustenis of the Paris-Meudon Observatory discusses a potential landscape of mountains and lakes on this strange, smog-filled world. ---- Astrobiology Magazine (AM): People thought for many years that Titan was completely covered by a hydrocarbon ocean. When did that change?Athena Coustenis (AC): When I started out in this field in 1987, Jonathan...

ESA -- One year after Mars Express' arrival at Mars, the mighty rules of celestial mechanics have again set Christmas as the date for a major ESA event in deep space. At 1.25 billion km from Earth, after a 7-year journey through the Solar system, ESA's Huygens probe is about to separate from the Cassini orbiter to enter a ballistic trajectory toward Titan, the largest and most mysterious moon of Saturn, in order to dive into its atmosphere on January 14th. This will be the first man-made...

Seeing straight lines on a planet or moon may point to faultlines or icy breaks. Jupiter's moon, Europa, is covered in ridges that fractured its icy crust. But scientists are intrigued by what appears on Saturn's largest moon, Titan -- particularly when the lines seem to intersect like an arrowhead. Astrobiology Magazine -- As Cassini scientists work to understand the newly-exposed surface of Saturn's largest moon, Titan, they have found an interesting arrowhead-shaped feature, shown in the...

ESA -- Lalala, Bald James Dean, Hot Time and No Love are all heading for Titan. It is now seven years since these four pop songs, composed by musicians Julien Civange and Louis Ha©ri, stole aboard the European Huygens probe heading for Titan, the main moon of Saturn. After its long journey Huygens is due to reach to surface on 14 January 2005. ESA wanted to have music on board to arouse the interest of the world's public, particularly the young, and to leave a trace of humanity in...

Billions of dollars are pumped into extraterrestrial exploration each year in the search for the ultimate prize - the discovery of life on other planets. But are we looking in all the right places? Prof Steven A Benner, who is working with NASA on the design of the next generation of Mars probes, believes that life could flourish without any need for water. In the December issue of Current Opinion in Chemical Biology, he and his colleagues at the University of Florida describe how organisms...

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...
