Highest mountain Titan showed in the picture


Geophysics 47-th Lunar and planetary conference, which opened on 22 March 2016 in the Woodlands (USA), presented new results on the research Titanium. Scientists showed radar images of the highest mountain, the largest satellite of Saturn, and also presented the latest version of the map of this heavenly body. It is reported by NASA.

The highest point of the Titan is a mountain of Mithrim. It reaches a height of 3337 meters and is located in the center of the bottom of the ridge (shown in the figure). Above and to the North of it is another mountain with a height of 2807 meters.

The card is an update version, approved in 2012, the International astronomical Union. By tradition, the names of most of the uplands of Titanium are given in honor of the mountains of middle-earth novels by John Tolkien. New map added nine sites, including the mountainous region of Moriah. Previously it contained 12 objects, plus the point of the landing module Huygens.

NASA also presented four Titan cards installed in the period from 2004 to 2015 the station Cassini images. During this period the machine on average once a month, flying to various parts of the satellite of Saturn. Each of the two map series allows you to focus on certain characteristics of the satellite, in particular, the impact crater with a width of 80 kilometers and the area of landing of the descent module of Huygens.

The first column represents a snapshot in the infrared range with a wavelength of two micrometers. The second column of images assembled by combining two images obtained at different wavelengths. The third is a composition of pictures taken with three filters: red (five microns), green (two microns) and blue (1,27 micron). The rightmost column is obtained by mounting with the use of these three colors and things sharpness. It allows you to consider on the surface of Titanium with different topography.

To create maps used scientific instrument VIMS (Visual and Infrared Mapping Spectrometer) and radar automatic station Cassini. The images do not reflect the natural color of Titanium, since observation of its surface at optical wavelengths is not possible because of the extremely dense atmosphere of Saturn’s moon and its seasonal changes. In the above images, the light areas meet irregular terrain, while darker regions are associated with more smooth surfaces.

According to scientists, under the icy crust of Titan is hidden a mantle of liquid water, which is under high pressure (including the thick atmosphere of the satellite of Saturn), flowing slowly and over time deforms near-surface layers. This leads to the formation on the titanium of high mountains. The latter processes may also be stimulated by rotations of the Titan (crust, mantle and core of the satellite can at different speeds to rotate around their axis) and tidal interaction with Saturn.

Titan — the largest of the 62 moons of Saturn. He’s almost one and a half times larger than the moon in diameter and almost twice the mass. In the atmosphere of Titan is dominated by nitrogen with admixtures of methane forming clouds. Surface temperature on Saturn is equal to minus 180 degrees Celsius, and its atmosphere and on its surface there is almost no liquid water and carbon dioxide. The role of liquid water on Titan play liquid methane and ethane. A moon of Saturn contains a lot of water bodies with these hydrocarbons. The Titan is also possible hydrocarbon precipitation and seasonal changes.

The mission Cassini-Huygens is a joint project of NASA, ESA (European space Agency) and Italian space Agency. Operational management of the project is carried out by the jet propulsion Laboratory in Pasadena city (CA, USA) for NASA. The main objective of the project is to study Saturn, its rings and largest satellite of the planet, Titan. The mission launched 15 October 1997 from Cape Canaveral in Florida on 1 July 2004, went into orbit of Saturn. December 25, 2004 from the satellite separated probe Huygens, 14 January 2005 landed on Titan’s surface.
