Curiosity, Ekim 2023’ten bu yana Mars’\u0131n s\u00fclfatlar a\u00e7\u0131s\u0131ndan zengin bir b\u00f6lgesini, yani k\u00fck\u00fcrt i\u00e7eren ve suyun buharla\u015fmas\u0131yla olu\u015fan bir t\u00fcr tuzu ara\u015ft\u0131r\u0131yor.

Bu mineraller di\u011fer malzemelerin bir kar\u0131\u015f\u0131m\u0131 i\u00e7erisinde bulunuyordu. Bununla birlikte s\u00fclf\u00fcr minerallerinin suyun buharla\u015farak geride s\u00fclf\u00fcr b\u0131rakmas\u0131yla meydana geldi\u011fi de biliniyor.<\/p>\n

Ancak Curiosity’nin k\u0131sa s\u00fcre \u00f6nce ke\u015ffetti\u011fi elemental<\/strong> (saf) s\u00fclf\u00fcr\u00fcn varl\u0131\u011f\u0131<\/strong> tam bir muamma. Zira ke\u015fif arac\u0131n\u0131n bu b\u00f6lgede olduk\u00e7a y\u00fcksek miktarda saf s\u00fclf\u00fcr bulmas\u0131 beklenmiyor ve tahmin dahil edilmiyordu<\/strong>.

<\/span> D\u00fcnya\u2019da baz\u0131 bakteri t\u00fcrlerinin hidrojen s\u00fclf\u00fcr (H2S) \u00fcreterek organik maddeleri par\u00e7alayabildi\u011fini biliyoruz. Bu H2S, oksijenli ortamda oksitlenerek s\u00fclf\u00fcre d\u00f6n\u00fc\u015febiliyor. Bu i\u015flem, \u00f6zellikle s\u00fclf\u00fcr bak\u0131m\u0131ndan zengin su kaynaklar\u0131 ve batakl\u0131klarda g\u00f6r\u00fcl\u00fcyor. Ayr\u0131ca volkanik faaliyetler sonucunda veya tuz kubbelerinin su ile reaksiyona girmesi sonucunda s\u00fclf\u00fcr yataklar\u0131 olu\u015fabilmekte.

Curiosity\u2019nin ke\u015ffi b\u00fcy\u00fck ve cevaplanamayan bir s\u00fcrpriz olsa da esas\u0131nda bu, Mars\u2019\u0131n saklad\u0131\u011f\u0131 gizemlerin ne kadar b\u00fcy\u00fck oldu\u011funa i\u015faret ediyor. Ara\u00e7, 2014\u2019ten bu yana kilometre y\u00fcksekli\u011findeki Sharp Da\u011f\u0131<\/strong>‘n\u0131n \u00f6zel bir b\u00f6l\u00fcm\u00fcn\u00fc ara\u015ft\u0131r\u0131yor. Curiosity, y\u0131l\u0131n ba\u015f\u0131ndan beri bu da\u011fdan a\u015fa\u011f\u0131ya uzanan Gediz Vallis<\/strong> kanal\u0131n\u0131 inceliyor. Da\u011f\u0131n her bir katman\u0131 Mars tarihinin farkl\u0131 bir d\u00f6nemini temsil ediyor ve kanal\u0131n da eskiden bir dere veya nehir yata\u011f\u0131 oldu\u011fu tahmin ediliyor.<\/p>\n

<\/span> Curiosity\u2019nin g\u00f6nderdi\u011fi g\u00f6rseller ve veriler ise bu kanala dair tahminleri olduk\u00e7a g\u00fc\u00e7lendiriyor. Zira burada suyun neden oldu\u011fu kimyasal reaksiyonlar\u0131n baz\u0131 kayalarda beyaz hale \u015fekilleri<\/strong> olu\u015fturdu\u011fu g\u00f6r\u00fcl\u00fcyor. Ayr\u0131ca kanal\u0131n taban\u0131nda birikmi\u015f tortu ve malzemeler de ke\u015ffedildi. Bunlar\u0131n toprak kaymalar\u0131, seller ve ta\u015fk\u0131nlar<\/strong> taraf\u0131ndan ta\u015f\u0131nd\u0131\u011f\u0131 d\u00fc\u015f\u00fcn\u00fcl\u00fcyor. Curiosity\u2019nin 2011 y\u0131l\u0131nda ba\u015flayan maceras\u0131 ise tam olarak bu t\u00fcr aktiviteleri incelemek. Zira bilim insanlar\u0131 Mars\u2019\u0131n bir zamanlar mikrobik de olsa ya\u015fam bar\u0131nd\u0131rd\u0131\u011f\u0131n\u0131 d\u00fc\u015f\u00fcn\u00fcyor.
