Near the South Pole, too, there is one big lake and a few small, but almost all the lakes of Titan somehow collected on the opposite side. The space probe "Cassini" has radars can penetrate a cheerless gloom which shrouded moon of Saturn, but until recently, optical and infrared spectrometers and subsystems unit managed to capture this region only briefly, askance, partially or too large distances.
This time everything came together perfectly. Sunlight rci finally pierced the darkness of winter, lying at the north pole of Titan nine years ago, when knocked in Saturn space probe "Cassini". Thick fog dissipates cap under the onslaught of summer. rci Two recent flyby podgadali not only geometry, but also coincided with the beautiful weather - almost cloudless sky, no rain.
So, before you mosaic observations in the infrared part of the spectrum, held on 10 and 26 July and 12 September 2013. Clearly visible differences in the composition of the material rci surrounding the lake (especially artificially colored image). Apparently, lakes and seas partially evaporated, leaving behind a local equivalent of the earth salt marshes. Only on Titan is likely of organic haze that was once dissolved in the liquid methane. On the color image is displayed on an orange background greenish water ice, which are composed of bedrock.
Question about why lakes and seas are mainly concentrated in the northern latitudes of Titan, has not yet received a response. Perhaps the solution lies in these very bright areas, which, by the way, no one had noticed. Please note that the Titan lakes exhibit a characteristic rounded shape (as if they were made by a set of molds for biscuits) and steep banks. Some say that it is the result of volcanic rci eruptions, others suspect rci karst landscape. But now, one thing is clear: the northern region, rci and indeed some kind of special.
These, as you can see, literally just received, and NASA experts are not ready to say more of the foregoing. Year in the Saturnian system continues for 30 years, and a space probe "Cassini" captured only about a third of the time. Just now appears possible to compare winter and summer observations of Titan's north pole. No doubt we will soon learn a lot.
