Informaciya s Encelada udivitel'na i vse bolee i bolee soglasuetsya so skazannym nami v stat'e. Imeetsya v vidu vozmozhnost' molekulyarnoi formy zhizni ne trivial'nogo vida. Vzyato mnoi s Foruma Novosti Kosmonavtiki. (ssylka na Forum NK) http://www.novosti-kosmonavtiki.ru/phpBB2/ viewtopic.php?t=175&start=1110&sid=c4be617e96ffe69aef77ffc7f4a65bec Soobshenie Imxotep Kak izvestno, fontany Encelada predstavlyayut soboi potoki vodyanogo para i ledyanoi pyli, vyryvayushiesya iz 4- h dlinnyh razlomov na yuzhnom polyuse sputnika. Dolgoe vremya schitalos', chto eti 2 sostavlyayushie vedut sebya po- raznomu : potoki pyli letyat bolee menee v odnom napravlenii, a gaz pochti srazu rasshiryaetsya, obrazuyu diffuznyi oreol. Odnako nedavnie izmereniya Kassini vyyavili dovol'no rezkuyu granicu, potoki gaza i pyli vedut sebya kak odna moshnaya struya s plotnost'yu v 20 raz bol'she predskazannoi. Eto oznachaet, chto rezhim istecheniya blizok k sverhzvukovomu, i podrazumevet bol'shie davleniya i temperatury v nedrah Encelada. http://planetary.org/image/PIA10362.png Plotnost' fontanov Encelada. Vidna rezkaya granica na vhode v struyu. http://planetary.org/image/PIA10356_lg.png Mass-spektr fontanov Encelada po dannym INMS Neozhidanno vysokaya plotnost' okazalas' kak nel'zya kstati pri izmerenii himicheskogo sostava. Blagodarya bolee chetkomu signalu mass-spektrometra INMS byl razreshen pik v oblasti tyazhelyh ionov s massami ~ 40. Eto organicheskie molekuly i produkty ih raspada etan, metan, propan, propen, acetilen, formal'degid, HCN. Otnositel'nye koncentracii organicheskih veshestv okazalis' ochen' blizki k organike, obnaruzhennoi v kometah http://planetary.org/image/PIA10357_lg.png Na risunke vyshe na izmerennyi mass-spektr naneseny tipichnye koncentracii teh zhe veshestv v kometnom materiale (belye skobki). Po mnogim pokazatelyam sovpadenie bolee chem udivitel'no i adekvatnomu ob'yasneniyu poluchennyi rezul'tat poka ne poddaetsya. Mozhet li v sisteme Saturna poyavit'sya sputnik s sostavom kak u ob'ektov poyasa Koipera? Ili zhe izmerennye koncentracii yavlyayutsya sledstviem protekayushih vnutri Encelada processov? Otvet eshe predstoit uznat'. http://planetary.org/image/enceladus_spole_cirs_comparison_lg.jpg Temperaturnye karty yuzhnogo polyusa Encelada. Sleva - dannye 2005 goda., sprava 2008-go Drugie vazhnye podrobnosti o yuzhnom polyuse Encelada byli polucheny IK-spektrometrom CIRS - vpervye udalos' razreshit' teplovoe izluchenie ot otdel'nyh treshin. Vchetvero luchshee prostranstvennoe razreshenie takzhe pozvolilo vyyavit' uchastki s temperaturoi znachitel'no vyshe, chem bylo izvestno ranee. Tekushii rekord 180 K (-93 S) - pochti ne ostavlyaet somnenii, chto gde-to vnutri temperatura priblizhaetsya k 0 S i sushestvuet zhidkaya voda. http://planetary.org/image/PIA10361_fig1_labeled_lg.jpg Na bolee podrobnoi karte vidno, chto temperatura poverhnosti dovol'no plavno menyaetsya vdol' treshin, nesmotrya na to, chto strui izvergayutsya iz nedr lish' v neskol'kih diskretnyh mestah (zvezdochki). Vo vremya sleduyushego proleta v avguste Kassini poluchit eshe bolee podrobnuyu temperaturnuyu kartu treshiny Damask, gde nahoditsya samaya goryachaya tochka poverhnosti Encelada. po materialam planetary.org
