Re: Strannye kamni Marsa (Spirit, Opportunity).

Eti strannye shariki... Zhal' chto ssylki neaktivny. Nizhe est' ssylki, na fotografii sharikov-gematitov iz kratera Igl eto pervye mesyacy prebyvaniya Opportuniti na Marse (2004g). Predlagayu obratit' vnimanie na evolyuciyu sharikov. Tak vot, uvidev na fotografiyah shariki na kamnyah eksperty NASA, (kak dumayu i my vse) srazu zhe zametili eti samye sinie krasivye shariki. I ni kto togda ne somnevalsya v tom chto eti shariki est' gematity. Sobstvenno drugogo nikto ne zhdal kak i to chto poristye kamni eto kuski lavy. Nizhe nekotorye fotografii chetyreh letnei davnosti, otkroite hotya by nekotorye ne polenites' ili mozhno peremestit'sya na AstraGalaktiku gde ssylki aktivny. Rannyaya vesna Feb 28, 2004 at Eagle crater, Meridiani Plain, Mars http://tonos.ru/images/articles/mars/8/image013.jpg Tak vyglyadyat shariki cherez tri mesyaca v nachale marsianskogo leta Opportunity May 31, 2004 ( sol 125) Ekonom rezhim http://tonos.ru/images/articles/mars/8/image032.jpg adres na stranichku http://www.flickr.com/photos/hortonheardawho/273892406/ Fotografii sdelany primerno v odnom meste s raznicei v tri mesyaca. (Otkrytye shariki est' i zimoi i letom, no pritoplenye tol'ko zimoi i vesnoi, letom takih net.) Eto dopolnitel'nye ssylki (Ssylki mozhno propustit' do poyasnitel'nogo teksta). Ssylka na stranichku iz arhiva NASA http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20040302a.html Otdel'naya fotografiya iz etogo spiska. http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20040302a/16-jg-02-mi1-B035R1_br.jpg Krupnyi plan http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20040302a/15-jg-01-elcap-texture-B038R1_br.jpg (fotografii v ekonom rezhime v maksimal'nom razreshenii mozhno otkryt' po verhnei ssylke) 9 Fevralya Str. iz arhiva http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20040209a.html Foto http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20040209a/ 1M129515692EFF0312P2939M2M1_mi_RobtE_full-B016R1.jpg 12 FEVRALYa 2004 Str. iz arhiva http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20040212a.html Fotografiya http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20040212a/06-ml-2-rock-B019R1.jpg 28 fevralya 2004 g. http://www.flickr.com/photo_zoom.gne?id=4122284&size=o 3 marta Foto http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20040303a/xpe_el_cap_2_holes-B039R1.jpg Panorama krupnym planom visyashih sharikov http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20040323a/LastChance_F-B058R1.jpg Stranica arhiva http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20040323a.html Panorama kamnei v kratere Igl. http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20040303a/xpe_el_cap_2_holes-B039R1.jpg Kommentarii. Tak vot, srazu nikomu i v golovu ne prishlo gadat' chto eto, da, i ne moglo priiti. No, teper' po proshestvii vremeni, kogda u nas est' mnogie sotni tysyach fotografii pochti za chetyre goda raboty, posmotrite vnimatel'no i otmet'te sleduyushee. Rannei vesnoi na fotografiyah shariki matovye, mnogo zatoplennyh kak by rozhdayushihsya. Letom i osen'yu blestyashie, krasivye polnost'yu oformlennye shariki i TOL'KO NA POVERHNOSTI. Prichem hot' poverhu kamnya hot' na bokovoi stenke, shariki visyat edva kasayas'. Visyat kak yagody na kustah ili kapel'ki smoly na stvolah derev'ev. Poetomu esli by byla sdelana bokovaya fotografiya skaly ili drugogo kamnya dlya sluchaya spelyh, sozrevshih sharikov to eto stalo by prosto brosat'sya v glaza t. e. osoboe sostoyanie yarkih, ideal'nyh sharikov. Pri sushestvuyushem tol'ko pryamom rakurse eto menee zametno. Dalee, vnizu na peske my takzhe vidim shariki bol'shinstvo polnost'yu otkrytye. A ved' v prisypannom ili polnost'yu zasypannom sostoyanii sharikov dolzhno byt' gorazdo chashe. Soglasimsya, v sluchae versii eroziinogo vyvetrivaniya gematitnyh sharikov, to process erozii dlitel'nyi (prichem pri sil'nom uvelichenii sledov erozii ne vidno). I esli s sharikami nichego ne sluchilos' pri ih yakoby dlitel'nom vyvetrivanii, to chto osobennogo moglo by proizoiti pod sloem pyli? Togda kak fotografii rvov prodelannyh kolesami roverov pokazyvayut pod sloem pyli i peska sharikov net. Hotya skazannoe konechno nichego ne govorit krome neobhodimosti proverki. To chto shariki menyayut vid i cvet po sezonu samo soboi vidyat i v NASA. A v dannoe vremya gematit obrazovyvat'sya na Marse ne mozhet, poskol'ku, dlya etogo processa nuzhna voda, a ee ponyatnoe delo net i byt' ne mozhet. Dalee. Voz'mem poslednie fotografii vblizi i ryadom s kraterom Viktoriya i sravnim s fotografiyami na ego vnutrennih sklonah (Opportuniti 4 nedeli kak vnutri kratera). Sklon kratera Viktoriya Opportunity Sep 14, 2007 ( sol 1294) http://www.flickr.com/photo_zoom.gne?id=1483821263&size=o Pri obychnom skatyvanii sharikov po sklonu, imeyushiesya na sklone uglubleniya dolzhny byt' zapolneny plotnee, chem bugry i vozvysheniya. Shariki yavno izbegayut uglublenii, chto mozhno ob'yasnit' kak izbeganie zatenennyh mest. Skoree vsego oni voznikayut-obrazuyutsya-rastut imenno v teh mestah gde i nahodyatsya v dannoe vremya. Na fotografiyah vidno, chto staryi sled posle 3-4 mesyacev provetrivaniya snova pokryvaetsya sharikami. Staryi sled, Opportunity Jul 15 - Aug 4, 2007 ( sol 1234 - 1254 ) http://www.flickr.com/photos/hortonheardawho/1041371567/ Opportunity Aug 4,15,21, 2007 ( sol 1254 1265 1270) http://www.flickr.com/photos/hortonheardawho/1260309822/ Tak vot vblizi kratera my vidim nepreryvnyi pokrov iz sharikov. Na vnutrennih sklonah vverhu po kromke sklona sharikov znachitel'no men'she no est', vnizu pochti net, a te chto est' uzhe v drugom sostoyanii. Yavno svalivshiesya sverhu, pobitye i polomannye. No, ved' soglasno gematitnoi versii, eto nepravil'no. Na Zemle gematity eto prosto zalezhi i pri dannyh usloviyah kratera Viktoriya postepenno skatilis' by vniz, po doroge zapolnyaya vse treshiny i uglubleniya. Voznikayut voprosy. 1. Pochemu shariki tol'ko na poverhnosti, a v pochve net. 2. Pochemu v odin sloi? 3. Pochemu vnizu sklona kratera Viktoriya sharikov namnogo men'she chem na verhu? Ved' oni mogut skatyvat'sya tol'ko vniz, a ne naoborot. Udivitel'no, no net ni odnoi fotografii, gde by byl snyat (a voobshe horosho i pravil'no pod mikroskopom) sledy rovera na tverdom grunte. Ya imeyu v vidu, chto esli by sravnit' diametry pyaten razdavlennyh sharikov i nahodyashihsya ryadom celyh, to mozhno bylo by primerno ocenit' ih prochnost'. No takih snimkov net. A esli by Opportuniti vstrechaya uchastki s ogolennym zhestkim gruntom, periodicheski delal takie snimki, to voznikla by vozmozhnost' sravnit' izmenenie prochnosti sharikov zima-vesna-leto. V 8 chasti ya privel dostatochno mnogo fotografii sharikov i eshe bol'she ssylok. http://tonos.ru/articles/marslife8 Nizhe fotografii iznutri kratera Viktoriya i fotografii kamnei snyatye Spiritom pod mikroskopom (poverhnost' kamnei kak oplavlennaya i vsyudu otverstiya, no ne ot erozii), Opportunity Sep 14, 2007 ( sol 1294) http://www.flickr.com/photo_zoom.gne?id=1500164852&size=o Ekonom http://farm3.static.flickr.com/2250/1500177842_cc36304c65.jpg?v=0 Verhnyaya chast' sklona, sharikov na sklone men'she, no oni est'. V verhnei chasti sklona shariki est' dazhe na kamnyah, no na peschano-pylevyh uchastkah v yamah ih net. Hotya yamy zapolneny pyl'yu eto po logike prosto gotovye lovushki dlya sharikov. Otsyuda predstavlyaetsya logichnym chto vnizu sharikov net glavnym obrazom iz-za vetrovoi teni i sootvetstvenno otsutstviya potokov pyli, kotorye ochevidno neobhodimy dlya ih obrazovaniya. http://marsrovers.jpl.nasa.gov/gallery/press/opportunity/20071015a/1F245542955EFF8736P1151L0M1.jpg http://marsrovers.jpl.nasa.gov/gallery/all/1/p/1321/1P245461419EFF8730P2377L2M1.JPG Na nizhe privedennoi fotografii shariki kak budto skatyvalis' po treshine. No na vid eto uzhe povrezhdennye, deformirovannye shariki. Nalichie takih sharikov vnizu, tol'ko podtverzhdaet versiyu ih obrazovaniya-rosta vverhu sklona, a zatem po mere otmiraniya skatyvaniya vniz. A nebol'shoe kolichestvo sharikov vnizu, priznak ih nedolgovechnosti (raspadayutsya bystree chem nakaplivayutsya). http://marsrovers.jpl.nasa.gov/gallery/all/1/m/1322/1M245542222EFF8736P2976M2M1.JPG Opportunity Oct 13, 2007 ( sol 1322) http://www.flickr.com/photo_zoom.gne?id=1763216709&size=o Napomnyu, chto ranee my utverzhdali chto vnizu sklona kratera Viktoriya sharikov net. Eto podtverdilos' v polnom vide, v tom smysle, chto sharikov malo i oni v sil'no povrezhdennom sostoyanii. Vse vyglyadit tak, kak esli by shariki rosli naverhu i po verhnei kaime kratera i popadali vniz posle skatyvaniya (dlya ih obrazovaniya neobhodim solnechnyi svet i potoki pyli). Takzhe mozhno ubedit'sya, chto vnizu tol'ko skativshiesya shariki, a celyh net. A nemnogo sharikov, po prichine ih nedolgovechnosti. Takim obrazom, shariki formiruyutsya na otkrytoi horosho produvaemoi i osveshennoi poverhnosti. Poetomu vulkany, meteority i gematity zdes' yavno ne prichem. - A, naskol'ko shariki zhivye neobhodimo proyasnit' v dal'neishem eksperimental'no. Naprimer, razdavit' shariki kolesami na zhestkoi poverhnosti (raznye i odinakovye, izmenenie sostoyaniya po sezonu), nakryt' ten'yu (nakryt' kamnem), sdvinut' v storonu, nasypat' holmik i t. p. http://marsrovers.jpl.nasa.gov/gallery/all/1/n/1329/1N246174815EFF8788P1675L0M1.JPG http://marsrovers.jpl.nasa.gov/gallery/all/1/n/1329/1N246176353EFF8788P0775R0M1.JPG Obratim vnimanie na mesto Opportuniti, spustilsya vsego-to, a sharikov kak vidim uzhe net Tak chto my dumaem o marsianah? Zhizn' eto ili nam tol'ko kazhetsya??
