| Cassini Completes Second Flyby of Titan |
| 2004-12-15 |
| The Cassini spacecraft completed a successful rendezvous with Saturn's moon Titan Monday. 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 Standard Time). As anticipated, the spacecraft came within 1,200 kilometers (750 miles) of Titan's surface. As with the last flyby, a major goal of this flyby is to measure the thickness of Titan's atmosphere. This information will help determine whether Cassini can safely get closer to Titan on subsequent flybys, and will also be used to verify that Huygens atmosphere models are correct. Titan is a prime target of the Cassini-Huygens mission because it is the only moon in our solar system with a thick smoggy atmosphere. The Huygens probe, built and operated by the European Space Agency, is attached to Cassini. After its Christmas Eve release, it will descend through Titan's atmosphere on Jan. 14, 2005, as it collects atmospheric data down to the surface. Tuesday morning, Cassini flew by Saturn's icy moon Dione at a distance of 72,500 kilometers (45,000 miles). Images and science results from both flybys will be presented at a news conference that will take place on Thursday, Dec. 16, at the American Geophysical Union fall meeting in San Francisco.

| #1 Kewl! Now we need to get private enterprise involved in getting people into space. I still hope for the day when... " The chair now recognizes the Gentelman/Gentlewoman from Planitia Utopia..." or Tharsis, or Noctis Labryntius, or where ever we go and settle. |
