PASADENA, CAA mere two weeks into the New Year, already what will undoubtedly be the biggest story of the year will have taken place: the upcoming Jan. 14 landing of the Huygens space probe on Titan, Saturn's immense moon. 'The probe could impart invaluable clues about the evolution of our own planet, as Titan is the only moon in our solar system with a fully developed atmosphere,' Jet Propulsion Laboratory spokesperson Dr. Gregory Bloom said. 'Meanwhile, the Cassini orbiter will continue to photograph Saturn's other moons throughout the year, delivering what will assuredly be dazzling views, and possibly revealing more lunar atmospheres, or even new moons. It's exhilarating to be living in these incredible times.' Asked whether the spacecraft's four-year tour of the Saturnian system might tell us more about how Saturn's rings were formed, Bloom became coy, saying, 'You'll just have to wait until May, when Cassini will begin using radio occultation to estimate the size-distribution of ring particles.'
