Vehicle "Cassini" proved the existence of thousands of years of deep lakes on Saturn's moon

The Earth and Titan, the largest moon of Saturn, there is a remarkable similarity - the only space objects in the solar system, where there is a liquid lakes and the sea. While the planet they are filled with fresh water or salt water, Titan they consist of methane and ethane, a temperature of about 170-180 degrees Celsius minus. Recently, two groups of scientists examined data on device "Cassini" and found an interesting feature of the Titan - it is not only the small lakes that dry quickly, but also the deep waters, formed thousands of years ago.

small lakes explored by a team led by Shannon McKenzie. They worked with the data collected by the spectrometer VIMS instrument and Imaging Science Subsystem. Three lakes, which they saw in the winter, the spring has gone - they were small ponds that have evaporated or been absorbed into the surface of the satellite. Channels that can power these small ponds, the unit "Cassini" was not found, because their size is unlikely to exceed 300 meters.

Marco Mastrodzhuzeppe group, in turn, studied the deepest lake on the basis of data collected during the RADAR instrument convergence "Cassini" with Titan in April 2017. These reservoirs depth of 100 meters is mainly composed of methane, and thus differ from the largest in the southern hemisphere Titan Lake Ontario, which contained equal amounts of methane and ethane. satellite landscape suggests that the lakes were formed thousands of years ago and continue to grow thanks to the abundant rains and the minimum outflow.

Every time we make discoveries on Titan, it is becoming more and more mysterious. However, the new findings help to answer many of our questions and to understand the hydrology of Saturn.

In the future, space agency NASA plans to send a submarine to the Saturn moon, which falls on the depth of its seas. In 2018 for his trial we decided to use the pool, filled with methane and ethane.
