Titan, the Saturn's Moon,- is the second largest Moon in the Solar system and it is very similar to Earth (see the video below of this article). In July 2009 the radar of Cassini probe was recorded light reflection from a smooth surface of a liquid ocean in the infrared range on Titan, which was a direct proof of the existence of oceans beyond Earth. Radar of Cassini probe in the southern hemisphere of Titan showed a well-developed river systems, coastline and surface covered with liquid, but on the surface of Titan an all lakes, rivers, seas and oceans are composed of methane with temperature at the surface minus 180 degrees Celsius, and the existence of biological life forms at this temperature is practically impossible, then many scientists disappointed to find life on Titan's surface, but the opening of the new a very unusual phenomenon once again attracted the attention of many scientists to Titan- the comparison of images, which were taken by the probe of Cassini in 2005 and 2007 showed, that parts of the landscape of Titan moved 30 kilometers- this is only possible in the case, if the surface is of Titan consist from ice crust with thickness of about 500-1000 meters, but under of ice crust is located a liquid ocean with thickness of about two kilometer and a strong tidal effect of Saturn leads to heating of the core of Titan, and therefore the calculated temperature under the surface of Titan in this underground ocean is at least plus 10 degrees Celsius, which is very comfortable condition for the development of new forms of biological life on Titan. Note that in June 5, 2010 a group of scientists from NASA have made a declaration, that they have discovered on Titan a signs of a possible existence of the simplest forms of life on based on the analysis of data from the probe of Cassini, as a result of studying the unusual behavior of hydrogen on the surface of the satellite, the scientists believe - Titan's living organisms absorb gaseous hydrogen and acetylene, while in the process of life is formed methane on Titan in the end should be observed lack of reduction of acetylene and hydrogen near the surface. Measurements of spectrometer of Cassini probe showed a signs of disappearance of hydrogen and acetylene, so the detection of extraterrestrial life forms are possible on Titan in its underground ocean. Now is preparing Titan Saturn System Mission (TSSM), which was originally designed as a joint project between NASA and ESA for study of Saturn and its satellites- Titan and Enceladus. From the very beginning it was reported, that it is desirable to bring the Russian Space Agency to participate in Mission Titan Saturn System Mission, but the most interesting - the start of negotiations with the Russian Space Agency has coincided with successful completion of the drilling of ice in Antarctica to Lake Vostok, which indicates that the Titan Saturn System Mission would include Drilling of Titan's surface in 2029, when the probe will reache the surface of Titan after its launch in 2020 from the Earth. Note that, according to NASA, the probe of Titan Saturn System Mission will be equipped with very powerful and long-lasting source of energy - the Advanced Stirling Radioisotope Generator (ASRG), which it is totally unnecessary for the average research probe- it is necessary for the drilling installation.
