The sun shines on the north pole of Titan, and if you're lucky with the weather and the trajectory, the "Cassini" is mandatory to get new pictures of methane and ethane seas and lakes. Here and below the image NASA / JPL-Caltech / University of Arizona / University of Idaho. In the area of the south pole too, there is one big lake and several small, but almost all the lakes of Titan somehow assembled on the opposite side. "Cassini" has a radar capable of penetrating beneath the grim darkness which shrouded moon of Saturn, but until recently, optical and infrared spectrometers and subsystems unit managed to capture this area only briefly, sideways, in part or in too large a distance. This time, everything came together perfectly. Sunlight finally pierced the darkness of winter, lying at the north pole of Titan nine years ago when he knocked in Saturn "Cassini". elephantube Thick fog dissipates cap under the onslaught of summer. Two recent flyby podgadali not only the geometry, but also coincided with the beautiful weather - almost cloudless sky, no rain. So, before you mosaic of observations in the infrared elephantube part of the spectrum, held on 10 and 26 July and 12 September 2013. Clearly visible differences in the composition elephantube of the material surrounding the lake (especially on artificially colored image). Apparently, the lakes and the sea partly evaporated, leaving behind the local equivalent elephantube of terrestrial saline. Only on Titan is likely organics out of the haze that was once dissolved in liquid methane. On the color image is displayed elephantube on the background of greenish orange water ice, which are composed of bedrock. The question of why the lakes and the sea are concentrated mainly in the northern elephantube latitudes of Titan, has not yet received a response. Perhaps the answer lies in these very bright areas, which, by the way, no one had noticed. Please note that the lakes of Titan have the characteristic elephantube rounded shape (as if they were made by a set of molds for biscuits) and steep banks. Some say that this is the result of volcanic eruptions, others suspect karst landscape. But now, one thing is clear: the northern region and really kind of special. These, as you can see, literally just received, and NASA experts are not ready to say the above. A Year in the Saturn system elephantube can last for 30 years, and "Cassini" took only about a third of the time. Only now it is possible to compare the winter and summer observations of Titan's north pole. No doubt we will soon learn a lot. Prepared according to the NASA Jet Propulsion Laboratory.
