    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 -- The first pictures revealing the surface of Saturn's moon, Titan, were shown from Europe's Huygens probe showing what look like drainage channels on the surface of what until today has been a planet totally hidden from view. The first image, taken from an altitude of 16 kilometers, has a ground resolution of about 40 meters, said Martin Tomasko, principal investigator for Huygens' Descent Imager/Spectral Radiometer (DISR). Tomasko said that Huygens research teams now have about 350 pictures to work with. [Scroll to the bottom of this story to see raw image files of the Titan descent taken...

    DARMSTADT, Germany - A European space probe plunged into the hazy, mysterious atmosphere of Saturn's moon Titan on Friday, and elated mission controllers said it had opened its parachute to slow its descent as it gathers data. The Huygens probe had successfully restarted its systems and the mission, which could provide clues to how life arose on Earth, was going well, said Roberto Lo Verda, a spokesman for the European Space Agency. "It has entered the atmosphere, and entered it correctly," Lo Verda said. "We know the batteries are switched on, the parachute has deployed and it has slowed down...

    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,...

  • Scientists Find That Saturn's Rotation Period Is A Puzzle

    University of Iowa ^ | June 28, 2004 | Gary Galluzzo and Don Gurnett
    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. "Titan has a...

    This map illustrates the planned imaging coverage for the Descent Imager/Spectral Radiometer, onboard the European Space Agency's Huygens probe during the probe's descent toward Titan's surface on Jan. 14, 2005. The Descent Imager/Spectral Radiometer is one of two NASA instruments on the probe. The colored lines delineate regions that will be imaged at different resolutions as the probe descends. On each map, the site where Huygens is predicted to land is marked with a yellow dot. This area is in a boundary between dark and bright regions. This map was made from the images taken by the Cassini spacecraft...

    Saturn's Moon Iapetus Shows a Bulging WaistlineJanuary 7, 2005(Source: Jet Propulsion Laboratory) Iapetus in 3D More Iapetus Images Images returned by NASA's Cassini spacecraft cameras during a New Year's Eve flyby of Saturn's moon Iapetus (eye-APP-eh-tuss) show startling surface features that are fueling heated scientific discussions about their origin. One of these features is a long narrow ridge that lies almost exactly on the equator of Iapetus, bisects its entire dark hemisphere and reaches 20 kilometers high (12 miles). It extends over 1,300 kilometers (808 miles) from side to side, along its midsection. No other moon in the solar system...

    The Associated Press Updated: 11:07 p.m. ET Dec. 24, 2004The Cassini spacecraft launched a probe Friday on a three-week free-fall toward Saturnís mysterious moon Titan, where it will plunge into the hazy atmosphere and descend by parachute while its science instruments and cameras make observations. The European Space Agencyís Huygens probe is equipped with instruments to sample the chemistry of Titanís thick atmosphere, and may reveal whether the surface actually has lakes or seas of liquid methane and ethane that have been theorized by scientists. A signal confirming release of the probe was received at NASAís Jet Propulsion Laboratory at...

    The highlights of the first year of the Cassini-Huygens mission to Saturn can be broken into two chapters: first, the arrival of the Cassini orbiter at Saturn in June, and second, the release of the Huygens probe on Dec. 24, 2004, on a path toward Titan. The Huygens probe, built and managed by the European Space Agency (ESA), is bolted to Cassini and fed electrical power through an umbilical cable. It has been riding along during the nearly seven-year journey to Saturn largely in a "sleep" mode, awakened every six months for three-hour instrument and engineering checkups. In three days,...

    The European Space Agency's Huygens probe, carried millions of miles to Saturn on board the NASA Cassini space craft, has completed its final series of checks before separation. The check up, its sixteenth, found the probe in good health, according to the ESA. The Huygens probe will detach from Cassini on Christmas day, and drop into orbit around Titan, Saturn's biggest moon. On 15 January 2005 it will begin its descent into Titan's atmosphere, an event that might even be visible from Earth, provided you have a decent telescope, and are in the right place at the time.

    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...

    PASADENA, Calif. - NASA's Cassini spacecraft streaked by Saturn's smoggy moon Titan today, targeted to pass within just 750 miles of the planet-sized satellite to give scientists their first detailed glimpse of a world that, until now, has been shrouded in mystery. Moving through space at some 14,000 mph, Cassini made its closest approach to Titan at 12:44 p.m. EDT, using the moon's gravity to change its trajectory slightly for another Titan flyby Dec. 13. Today's encounter, the first of 45 Titan flybys planned over the course of Cassini's four-year primary mission, occurred while the $3 billion spacecraft was out...

    Probe preparing to plunge into Titan's atmosphere UNIVERSITY OF CALIFORNIA-BERKLEY NEWS RELEASE Posted: October 15, 2004 On Jan. 14, 2005, the Huygens probe will plow into the orange atmosphere of Saturn's moon, Titan, becoming the first spacecraft to attempt to land on a moon in our solar system since the Soviet Union's Luna 24 touched down on Earth's moon in 1976. Though scientists hope that Huygens will survive the plunge, it will be flying blind through hydrocarbon haze and methane clouds to a surface that could consist of seven-kilometer-high ice mountains and liquid methane seas. That's the picture that...
