[Boiler Plate]
Saturnian System

Largest moon of Saturn and the only known moon to have a thick atmosphere. Only body known to have bodies of liquids on its surface other than the Earth, which are composed of hydrocarbons. Landed on by the Huygens probe and mapped by the Cassini orbiter.

Titan Places in the NewsEdit

Lakes

  • Ontario Lacus - Largest hydrocarbon lake in Titan's southern hemisphere, near the poles, roughly the size and shape of Lake Ontario and shaped somewhat like a footprint. The lake is extremely shallow by Earth standards, only 0.5-3 meters thick, which were shown to rise and fall with the seasons. It is also extremely flat, with waves rising no more than a dime's width, indicating virtually non-existant winds at the time of the measurements. The first observed well developed river delta flows into it. Ethane has been identified in the lake.
  • Kraken Mare- The largest lake in Titan, located in the northern polar regions. A surface probe proposed for the Titan Saturn System Mission would splash down in this lake. It is five times the size of Lake Superior. Light was detected gleaning off of this lake.
  • Ligeia Mare - A northern hydrocarbon lake on Titan about the size of Lake Superior. It is the current proposed target for the Titan Mare Explorer lander. It was found to be deeper than Ontario Lacus in the southern hemisphere and probably formed via a different mechanism.
  • Punga Mare - Punga Mare

Sand Seas

Craters

  • Ksa Crater - A Medium sized (30 km) crater on Titan with a central peak and dark floor. First seen by Cassini in 2006, it is located to the north-west of Xanadu, and is separated from it by sand dunes.

Albedo Features

  • Xanadu Regio - Bright continent sized (about the size of Australia) region of Titan first observed by the Hubble Space Telescope. Sand dunes mark the boundary of it and the adjacent dark Shangri-La plains.
  • Hotei Regio - Frigid area on Titan in SE part of Xanadu that contains cryovolcanoes (Hotei Arcus). Ammonia frost was found to evaporate in this region, perhaps after having been belched up from the cryovolcanoes.

Suspected Volcanic Features

  • Ganesa Macula - Ganesa Macula is a dark feature on Saturn's moon Titan. It is named after the Hindu god Ganesha. Ganesa has been tentatively identified as a cryovolcanic dome, although stereo radar maps show it not to be a volcanic dome.
  • Sotra Facula - Feature at Titan initially believed to be of cryovolcanic origin, as it appears to have three large conical features. It is more likely that these have been formed by meteors and other weathering processes.

Titan Saturn System in the NewsEdit

See http://en.wikipedia.org/wiki/Titan_Saturn_System_Mission
Mission that lost out to Jupiter-Europa mission, but put on backburner for possible future missions
Would have left by 2020 and used a Venus gravity assist to reach Saturn
Nasa would provide an orbiter (which would tour Saturn system before entering Titan orbit, including more Enceladus flybys), while ESA would provide a balloon and hydrocarbon lake lander
