Cassini diverts from collision course with moon Titan CASSINI MISSION STATUS REPORT Posted: December 28, 2004 NASA's Cassini spacecraft successfully performed a getaway maneuver on Monday, Dec. 27, to keep it from following the European Space Agency's Huygens probe into the atmosphere of Saturn's moon Titan. This maneuver established the required geometry between the probe and the orbiter for radio communications during the probe descent on Jan. 14. The probe has no navigating capability, so the Cassini orbiter had been placed on a deliberate collision course with Titan to ensure the accurate delivery of the probe to Titan. The Huygens probe successfully detached from the Cassini orbiter on Dec. 24. All systems performed as expected. The European Space Agency's Huygens probe will be the first human-made object to explore on-site the unique environment of Titan, whose chemistry is thought to be very similar to that of early Earth before life arose. Next for Cassini is a flyby of Saturn's icy moon Iapetus on Dec. 31. Iapetus is Saturn's two-faced moon -- one side is very bright, and the other is very dark. One scenario for this striking difference is that the moon's surface is being resurfaced by some material spewing from within. The Cassini spacecraft has been in orbit around Saturn since June 30, 2004, and has returned stunning pictures of Saturn, its rings and many moons. Titan has already been the subject of two close flybys by Cassini. With 43 more flybys planned and the in-situ measurements made by the probe, it is likely only a matter of time before Titan's secrets begin to unfold. The Cassini-Huygens mission is a cooperative project of NASA, the European Space Agency and the Italian Space Agency. JPL, a division of the California Institute of Technology in Pasadena, manages the Cassini mission for NASA's Science Mission Directorate, Washington, D.C. JPL designed, developed and assembled the Cassini orbiter. The European Space Agency built and managed the development of the Huygens probe and is in charge of the probe operations. The Italian Space Agency provided the high-gain antenna, much of the radio system and elements of several of Cassini's science instruments. |
