Re: Strannye kamni Marsa (Spirit, Opportunity).

Obratim vnimanie dyuny nahodyatsya tol'ko v odin sloi i imeyut odinakovuyu formu ne zavisimo ot osobennostei rel'efa bud'-to na sklone v provale ili sredi kamnei, slozhnoe mnogosostavnoe napolnenie chto kraine neestestvenno i dazhe nevozmozhno dlya obychnyh barhanov. [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_009138_2025.jpg [/img] Podrobnee eto mozhno rassmotret' nizhe, ssylka na polnuyu versiyu panoramy 2mbaita. http://hirise.lpl.arizona.edu/images/2008/details/PSP_007055_2015_cut_c.jpg Teper' rassmotrim evolyuciyu Sinei dyuny zapolnyayushei krater Viktoriya ot nachala do ee nyneshnego sostoyaniya. [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_006943_1655.jpg [/img] [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_007466_1655.jpg [/img] [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_006572_1665.jpg [/img] [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_006975_2010.jpg [/img] [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_007475_1785.jpg [/img] [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_007098_1685.jpg [/img] Vyskazhem sleduyushee predpolozhenie, sinie dyuny nahodyashiesya v kraterah v bol'shinstve sluchaev voznikayut iz-za ob'edineniya zmeevidnyh dyun, srastayushihsya poperechnymi peremychkami. No na dvuh nizhnih fotografiyah vidno chto proishodit ne tol'ko ob'edinenie sinei dyuny iz otdel'nyh zmeevidnyh dyun no idet i obratnyi process migracii elementov dyuny v svobodnoe sostoyanie. [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_005885_1825.jpg [/img] [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_008758_1720.jpg [/img] Na fotografii nizhe, po-vidimomu, process razmnozheniya. [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_009084_1745.jpg [/img] Odnovremennoe sushestvovanie po perimetru central'nogo kratera takogo Endurans ili Viktoriya vorotnichka iz bolee melkih kraterov s mini sinei dyunoi v kazhdom (sudya po cvetu) navodit na mysl' o dvoinom ili dazhe mnozhestvennoi forme razmnozheniya kak ot semyan tak i pobegov. Krater Viktoriya po perimetru sotni poltory melkih voronok, nekotorye sovsem svezhie. Opport'yuniti proehal mimo dvuh takih sovershenno noven'kih voronok! Nu ne mogut tak chasto padat' meteority i tak pricel'no! Imenno po perimetru na nekotorom udalenii. Togda kak na vnutrennem sklone vsego odin malen'kii krater. [img] http://tonos.ru/images/articles/mars/6/image076.jpg [/img] Krater Endurans vokrug melkie voronki. Meteority na peske? Bystro dolzhno zanesti. [img] http://tonos.ru/images/articles/mars/6/image085.jpg [/img] Dva obrazca malogo kratera-pobega pervyi u kratera Viktoriya sovsem noven'kii [img]http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20080102a/Sol1162B_P2299_L257F_th418.jpg [/ img] Staraya voronka, takih vokrug kratera Endurans nemalo [img] http://tonos.ru/images/articles/mars/6/image046.jpg [/img] Na nekotoryh fotografiyah mozhno uvidet' zastyvshie sobytiya iz zhizni nashei dyuny. Naprimer, napadenie na sineyu dyunu marsianskogo raka (po-vidimomu neskol'kih osobei, priblizhayushihsya k dyune pod poverhnost'yu). [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_006822_2060.jpg [/img] Neponyatnye processy razdeleniya a vozmozhno gibeli [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_007502_1495.jpg [/img] Yavnye priznaki smerti. Vozmozhno i meteorit. [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_007119_1700.jpg [/img] Eshe neskol'ko fotografii razlichnoi zhivnosti (takaya zhe igra prirody kak nu zemnyh vidov: kroliki, ezhiki, cherepahi). [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_007229_1810.jpg [/img] Shupal'ca resnichki i shupal'ca kanavki http://hiroc.lpl.arizona.edu/images/PSP/PSP_001440_1255/PSP_001440_1255_RED.browse.jpg Imenno resnichki kak organy adsorbiruyushie pyl' i SO2 pri ih prinuditel'noi ventilyacii, a ne shupal'ca os'minoga dlya mehanicheskogo zahvata i uderzhaniya. [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_008815_1660.jpg [/img] http://hirise.lpl.arizona.edu/PSP_008815_1660 Kanavki ulavlivayut osedayushuyu pyl' (vspomnim zapylennye SB Spirita!) zatem porciyami podnimayushimi pishu na verh (na fotografii eto sleva vnizu). Gde naprotiv kazhdoi kanavki-shupal'ca uzhe nahoditsya ranee podnyataya porciya, vozmozhno uzhe nasyshennaya SO2 i poluperevarennaya. [img] http://hirise.lpl.arizona.edu/images/2008/details/PSP_007018_1255.jpg [/img] Nemnogo v inom, drugom vide ne vse tozhe samoe, ne hvatatel'nye a pogloshayushie glotatel'nye organy. Dyuny v glubokom kratere a sila vetra pri formirovanii formy ne igraet roli?? Ved' veter v glubokom kratere zavedomo slabee. http://hirise.lpl.arizona.edu/PSP_007560_2450 Vnutri odnogo i togo zhe kratera raznonapravlennye dyuny http://hirise.lpl.arizona.edu/PSP_007558_1305 Sharovoe skoplenie dyun v smysle dvizhenie kak by k centru skopleniya. Kakim dolzhen byt' veter?? http://hirise.lpl.arizona.edu/PSP_007547_2415 Dyuny v skopleniyah imeyut raznoobraznuyu formu i orientaciyu ne imeyushuyu analogii u zemnyh barhanov. Krome etogo raznoobrazie form isklyuchaet vetrovuyu versiyu (vezde v odin sloi i odnotipnoi formy, krome etogo vezde prisutstvuet molodnyak). http://hirise.lpl.arizona.edu/images/2008/details/PSP_009075_1800_RED.thumb.jpg http://hirise.lpl.arizona.edu/images/2008/details/PSP_003800_1325_RED.thumb.jpg http://hirise.lpl.arizona.edu/images/2008/details/PSP_007172_2570_RED.thumb.jpg V pol'zu biogennoi versii dyun govorit harakter izmenenii nablyudaemyh s periodom vo vremeni http://hirise.lpl.arizona.edu/images/2008/details/PSP_007805_2505_cut.jpg A takzhe ogromnoe raznoobrazie form organizacii veshestva prosto nemyslimoe dlya peschanyh ili pylevyh barhanov. Razmery dyun ot 50 do 500 metrov.
