European scientific community is now actively engaged in study of the mission, which provides an unmanned probe landing on the surface of Saturn’s largest moon - Titan.
Among the planets that are in the solar system, Titan most similar to Earth. The satellite has a thick atmosphere, a diameter that is comparable to Mercury, and most importantly, a network of seas, rivers and lakes.
Titan Lake In-situ Sampling Propelled Explorer (TALISE) - the naming of a new European space mission. To Titan’s surface, according to the scientists, should land autonomous probe, which moves with the help of special propeller blades or wheels. What a mover is selected, the experts have not yet fully decided, as it is the most important, perhaps, the structural element of the device - the future titanohoda.
TALISE will, in all probability, move both on land and on water, so the choice of an engine greatly influence the success of bude the mission.
Originally planned landing probe into the center of the largest lake Ligeia Mare, located near the north pole of Titan. Next TALISE will have to head to the coast, the road to collect different scientific information. The expected duration of the new mission will be from six months to a year.
As you know, on Titan’s cold enough for the development of the life as we used to see in the world. But there are a lot of molecules, which are the "building blocks" of life and is of great interest to astrobiologists. Consisting mainly of nitrogen atmosphere satellite rich variety of organic compounds, as well as hydrogen cyanide, who played on some assumptions, an important role in the origin of life on Earth.
TALISE concept is being developed by experts of the scientific center of SENER and the Spanish Centre for Astrobiology in Madrid. TALISE is still at the stage of development of the whole concept. The next stage involves the development of mission planning and execution of its feasibility.
