| Cassini Scientist for a Day 2012 Competition - Results |
| Students from across Europe have been selected as winners of the Cassini Scientist for a Day 2012 competition. Coordinated by ESA, national competitions were held in several European countries, including Poland, Spain and Greece, with more than 1000 entries. An equivalent competition was run by NASA for schools in the US. |

| Cassini sheds light on cosmic particle accelerators |
| During a chance encounter with an unusually strong blast of solar wind arriving at Saturn, the international Cassini spacecraft detected particles being accelerated to ultra-high energies, similar to the acceleration that takes place around supernova explosions. |

| Cassini reveals Titan's atmosphere in reverse |
| With winter fast approaching, everyone living in Earth's northern hemisphere is well aware that major atmospheric variations are associated with the changing seasons. Now new observations made by the international Cassini spacecraft confirm that an even more dramatic atmospheric reversal takes place as the seasons shift on Saturn's giant moon Titan. |

| Saturn's giant storm reveals the planet's churning atmosphere |
| A recent study of the giant storm whirling on Saturn for the past two years, which became known as the "Great Springtime Storm", has given planetary scientists new clues about the planet's weather. Using a combination of data from the Cassini orbiter and ground-based telescopes, the scientists traced the storm's development from deep within the churning clouds in Saturn's lower atmosphere to altitudes hundreds of kilometres above the cloud decks, in the planet's stratosphere. There, two large pockets of warm air formed and later merged into one gigantic hot vortex that has been travelling around Saturn's northern hemisphere since mid-2011. The study of this storm and its associated vortex, which occurred unusually early in Saturn's 30-year-long weather cycle, suggests that waves play an important role in the energy transfer across the planet's atmosphere. |

| Bouncing on Titan |
| ESA's Huygens probe bounced, slid and wobbled its way to rest in the 10 seconds after touching down on Saturn's moon, Titan, in January 2005, a new analysis reveals. The findings provide novel insight into the nature of the moon's surface.

| Titan's tides point to hidden ocean |
| Nothing like it has been seen before beyond our own planet: large tides have been found on Saturn's moon Titan that point to a liquid ocean - most likely water - swirling around below the surface. |

| Far-off cousin of part-time African lake found on Titan |
| A region on Saturn's moon Titan has been found to be similar to the Etosha Pan in Namibia, Africa. Both are ephemeral lakes - large, shallow depressions that sometimes fill with liquid. |

| Cassini's radar observes Titan's tropical dune fields |
| Sand dunes are common on Earth, Mars, Venus and - unexpectedly - on Saturn's giant moon, Titan. Now detailed analysis of radar observations gathered during the Cassini spacecraft's flybys of cloud-shrouded Titan is enabling scientists to understand the distribution, shape and dimension of its exotic dunes. |

| Cassini samples the icy spray of Enceladus' water plumes |
| The NASA/ESA/ASI Cassini-Huygens mission has directly sampled the water plumes jetting into space from Saturn's moon Enceladus. The findings from these fly-throughs are the strongest evidence yet for the existence of large-scale saltwater reservoirs beneath the moon's icy crust. |

| Cassini finds ethereal atmosphere at Rhea |
| The Cassini-Huygens mission has detected a very tenuous atmosphere known as an exosphere, infused with oxygen and carbon dioxide around Saturn's icy moon Rhea. This is the first time a spacecraft has directly captured molecules of an oxygen atmosphere - albeit a very thin one - at a world other than Earth. |

| Europe maintains its presence on the final frontier |
| ESA has decided to extend the productive lives of 11 of its operating space science missions. This will enable ESA's world-class science missions to continue returning pioneering results until at least 2014. |

| ESA and NASA celebrate the fifth anniversary of Titan landing |
| Exactly five years ago today the European Space Agency's (ESA) Huygens Probe made history when it landed on Titan, the largest moon in the Saturnian system. The touchdown on the surface of Titan marked the first, and so far only, landing of a man-made probe in the outer Solar System. Today many of the scientists and engineers that worked on the mission will celebrate this anniversary in the science museum Cosmocaixa in Barcelona, Spain. They will share their memories with the public and reveal future projects, "much work remains to be done", says ESA's Huygens Project Scientist Jean-Pierre Lebreton, "Titan has many different environments to explore further with in situ probes". |

| Huygens legacy conference to mark fifth anniversary of Titan landing |
| On 14 January 2005 the European Space Agency's Huygens probe separated from the Cassini spacecraft and landed on Saturn's moon Titan. The touchdown on the surface of Titan marked the first, and so far only, landing of a man-made probe in the outer Solar System. To mark the fifth anniversary of this remarkable event, scientists will gather from 13-15 January at the CosmoCaixa science museum in Barcelona, Spain, to review the key scientific and engineering achievements of Huygens, to evaluate the current understanding of Titan, and to consider future Titan exploration missions. |

| Sodium salts point to subsurface ocean on Enceladus |
| The Cosmic Dust Analyzer (CDA) on board the Cassini spacecraft has found sodium (Na) in varying concentrations in virtually all of its in-situ measurements of the water ice particles in Saturn's E ring. This has important implications for the icy moon Enceladus as the moon's south polar plumes are considered to be the main source of these E-ring water ice particles. In an article published today in Nature, Frank Postberg and colleagues conclude that the amount and type of sodium-bearing minerals found in the CDA measurements strongly favour the presence of a subsurface liquid water reservoir on Enceladus. |

| Titan Fly-by - 22 June 2009 |
| On Monday, 22 June, the Cassini spacecraft returns to Titan for the mission's fifty-eighth targeted encounter with Saturn's largest moon: T-57. The closest approach to Titan occurs at 18:32:35 UTC, at an altitude of 955 kilometres above the moon's surface and at a speed of 6.0 kilometres per second. The latitude at closest approach is 42.2°S and the encounter occurs on orbit number 113. |
