Cercet\u0103torii au fost intriga\u021bi de rocile ciudate de culoare deschis\u0103 descoperite de roverul Perseverance al NASA pe suprafa\u021ba mar\u021bian\u0103.<\/p>\n

Rocile s-au dovedit a fi caolinit, un tip de argil\u0103 bogat\u0103 \u00een aluminiu, au raportat oamenii de \u0219tiin\u021b\u0103 \u00een studiul publicat \u00een revista Communications Earth & Environment.<\/p>\n

Pe P\u0103m\u00e2nt, caolinitul se formeaz\u0103 aproape \u00eentotdeauna \u00een condi\u021bii foarte calde \u0219i umede, precum cele din p\u0103durile tropicale.<\/p>\n

De obicei, se formeaz\u0103 \u00een roci care au fost lipsite de toate celelalte minerale de milioane de ani de precipita\u021bii regulate.<\/p>\n

Dar Marte de ast\u0103zi este cunoscut\u0103 pentru c\u0103ldura \u0219i usc\u0103ciunea sa, potrivit LiveScience<\/a>.<\/p>\n

\u201eA\u0219adar, c\u00e2nd vezi caolinit \u00eentr-un loc precum Marte, unde este sterp, rece \u0219i cu siguran\u021b\u0103 f\u0103r\u0103 ap\u0103 lichid\u0103 la suprafa\u021b\u0103, acest lucru ne spune c\u0103 odat\u0103 a existat mult mai mult\u0103 ap\u0103 dec\u00e2t exist\u0103 ast\u0103zi\u201d, a declarat Adrian Broz, specialist \u00een soluri la Universitatea Purdue \u0219i autor principal al studiului.<\/p>\n

Structura caolinitei observat\u0103 pe Marte<\/h2>\n

Broz \u0219i echipa sa au comparat structura caolinitei mar\u021biene, care a fost examinat\u0103 de mai multe instrumente de pe Perseverance, cu probe terestre prelevate din Africa de Sud \u0219i San Diego. Rocile p\u0103reau izbitor de similare, suger\u00e2nd c\u0103 s-au format \u00een moduri similare.<\/p>\n

Imaginile satelitare ale suprafe\u021bei mar\u021biene par s\u0103 arate depozite mai mari de caolinit \u00een alte p\u0103r\u021bi ale planetei. Cu toate acestea, Perseverance \u0219i alte rovere nu au explorat \u00eenc\u0103 acele zone.<\/p>\n

\u201eP\u00e2n\u0103 c\u00e2nd nu vom putea ajunge cu roverul la aceste aflorimente mari, aceste roci mici sunt singurele noastre dovezi de pe teren\u201d, a declarat Briony Horgan, om de \u0219tiin\u021b\u0103 la Universitatea Purdue \u0219i coautor al studiului.<\/p>\n

Prezen\u021ba caolinitei pe Marte \u00eent\u0103re\u0219te ipoteza c\u0103 Planeta Ro\u0219ie<\/a> a fost o oaz\u0103 tropical\u0103 la un moment dat, de\u0219i momentul \u0219i modul exact \u00een care s-a uscat sunt \u00eenc\u0103 dezb\u0103tute.<\/p>\n

Marte a r\u0103mas f\u0103r\u0103 ap\u0103 \u00een urm\u0103 cu 3-4 miliarde de ani<\/h2>\n

Ipotezele principale sugereaz\u0103 c\u0103 planeta \u0219i-a pierdut apa cu 3-4 miliarde de ani \u00een urm\u0103, c\u00e2nd c\u00e2mpul s\u0103u magnetic s-a sl\u0103bit suficient pentru ca v\u00e2nturile solare s\u0103 \u00eei distrug\u0103 atmosfera.<\/p>\n

Dar acest proces a fost probabil complex \u0219i multifacetic. Studierea acestor argile antice ar putea oferi oamenilor de \u0219tiin\u021b\u0103 mai multe informa\u021bii despre cum \u0219i c\u00e2nd Marte \u0219i-a pierdut apa, au spus cercet\u0103torii.<\/p>\n

Ar putea oferi, de asemenea, indicii despre poten\u021biala habitabilitate a lui Marte, a spus Broz, deoarece \u201etoate formele de via\u021b\u0103 folosesc ap\u0103\u201d.<\/p>\n","protected":false},"excerpt":{"rendered":"
