    DARMSTADT, Germany, Jan. 14 - A European spacecraft plunged through the murky atmosphere of Saturn's moon Titan on Friday and successfully came to rest on a bizarre landscape never before explored. Astronomers expressed joy at achieving the first landing on another planet's moon, particularly Titan, the only moon in the solar system with substantial atmosphere. "We clearly have a success," said Dr. Jean-Jacques Dordain, director general of the European Space Agency. "This is a fantastic success for Europe." The first pictures from the spacecraft, Huygens, did nothing to undermine the reputation of Titan as a strange place. One showed what...

    DARMSTADT, Germany - A European space probe landed safely on the surface of Saturn's moon Titan on Friday, a space official said, buoying hopes the mission would produce data that could shed light on the origins of life on Earth. Officials were jubilant as early signals showed the probe powering up for entry, then beginning the 2 1/2-hour parachute descent during which it was to gather information that could shed light on how life arose on Earth. Mission controllers were confident the Huygens probe made a soft landing because it was still transmitting steadily long after it should have landed,...

    The currently accepted rotation period of Saturn came from radio measurements obtained during the Voyagers 1 and 2 flybys of Saturn in 1980-81, and is 10 hour 39 minutes and 24 seconds plus or minus 7 seconds. The first hint of something strange at Saturn came in 1997 when Alain Lecacheux, Patrick Galopeau, and Monique Aubier, from Observatoire de Paris, published a paper in the Austrian Academy of Science Press reporting that Saturn's radio rotation period was about one percent longer than the value obtained from Voyager. Now, during the Cassini approach to Saturn, where the radio signals from the...

    Suicide probe takes Saturn mission to climax PARIS (AFP) - The most ambitious interplanetary mission ever launched reaches a climax when a clam-shaped probe plunges towards Titan in a suicidal quest to unlock the mystery of Saturn's biggest moon. If all goes according to plan, the death dive of the European probe Huygens could push back the frontiers of knowledge about the Solar System. For more than four hours, the scout will relay back to its mothership precious data which could help explain the chemical recipe that enabled life to appear on Earth several billion years ago.

    Something Oozed on Titan's Surface Summary - (Nov 8, 2004) NASA's Cassini spacecraft took this image of Titan as it sped past the moon on Oct. 26, 2004. It was taken from an altitude of 2,500 km (1,553 miles) using the spacecraft's aperture radar, which can penetrate thick clouds and reveal the texture of the ground underneath. The dark regions are areas which are smooth, and the bright areas are more bumpy. It could be that the smooth areas are cryovolcanic flows, where water-rich liquid has welled up from inside Titan's warmer interior and spread out on the surface. Full...

NASA TV/webcast coverage of Cassini's arrival at Saturn begins June 30, 6:30 pm Pacific time. Check this page frequently for mission updates. My up-close and personal relationship with Saturn is brand new. Sure, I'd seen the pictures and the "artist's conceptions" all my life. I'd read the stories, both science and fiction, and I believed. I had faith. I had faith that Saturn existed and that it had the rings that made it the single...

    Ringed planet's poles are on either side of its equator Pasadena -- The spacecraft called Cassini, now little more than a million miles from Saturn, is already establishing that the mysterious ringed planet's magnetic field is bizarrely unlike Earth's -- and more surprises are sure to come. Cassini's interplanetary course is to carry it Wednesday night into the first of 76 orbits around Saturn to begin its four-year mission, and scientists are awaiting that first close-in encounter with some anxiety.

    Saturn's peaceful beauty invites the Cassini spacecraft for a closer look in this natural color view, taken during the spacecraft's approach to the planet. By this point in the approach sequence, Saturn was large enough that two narrow angle camera images were required to capture an end-to-end view of the planet, its delicate rings and several of its icy moons. The composite is made entire from these two images. Moons visible in this mosaic: Epimetheus (116 kilometers, 72 miles across), Pandora (84 kilometers, 52 miles across) and Mimas (398 kilometers, 247 miles across) at left of Saturn; Prometheus (102 kilometers,...

    Instead of being concerned with the pestilence in the Parisian streets in his day, JeanDominique Cassini (16251712) continued studying the heavens. He discovered comets and planetary moons. Saturn's rings were first viewed by Galileo Galilei in 1610, but he saw them from the edge and misidentified them as two moons. Forty-five years later, Dutch astronomer Christiaan Huygens, using a telescope superior to Galileo's, determined the two moons to be a ring around Saturn. Another 20 years passed, and in 1675, Cassini discovered that Saturn's ring actually was divided into two rings. The large gap between them is still referred to...
  • Saturn's natural radio emissions raise questions about rotation

    PASADENA, Calif. (AP) - The U.S.-European Cassini spacecraft has been listening to natural radio signals from Saturn, and what it's hearing raises questions about the length of day on the ringed planet. Cassini found the rhythm of natural radio signals, regarded as the most reliable indicator of the length of day, shows a complete rotation takes 10 hours, 45 minutes and 45 seconds, plus or minus 36 seconds, NASA said in a statement Monday. That's about six minutes longer than the radio rotational period measured by the Voyager 1 and 2 spacecraft that flew by Saturn in 1980 and 1981....

    PASADENA, Calif. (AP) - Two decades and $3.3 billion in the making, an international exploration of majestic Saturn begins this month when a spacecraft slips through a gap in the shimmering rings to enter orbit. Culminating a nearly seven-year, 2.2 billion-mile journey through the solar system, the Cassini spacecraft will fire its engine Wednesday night to slow down and allow itself to be captured by Saturn. The maneuver will inaugurate a four-year, 76-orbit tour of the giant planet and some of its 31 known moons, including huge Titan. To scientists, Saturn and its spectacular rings are a model of the...

    The destination is within clear view, and a beckoning sight it is. Saturn and its creamy pastel bands of thick atmosphere shimmer in pale sunlight, and the majestic rings of dust and rock set it apart from the Sun's other worlds. Dancing about in rhythmic orbits are 31 known satellites, of which the most mysterious and inviting is the planet-size Titan. After a nearly seven-year voyage from Earth, the Cassini spacecraft is fast approaching the moment that scientists have dreamed of and planned for over the better part of their careers. The spacecraft is scheduled to swing into the orbit...

    NASA's Cassini space probe confirmed Saturday that it had completed a flyby of Saturn's largest moon, Phoebe, coming within 1,285 miles of the small, dark body. The craft's main antenna was pointing away from Earth during the flyby Friday afternoon. Engineers at the National Aeronautics and Space Administration's Jet Propulsion Laboratory in Pasadena, Calif., did not receive word of the craft's successful pass until 10:52 a.m. EDT Saturday, when the craft re-oriented itself and began transmitting pictures and data back to mission control. Most of the data and pictures will be released today, but the early unprocessed images show that...
