Bu atmosferik toz, g\u00fcne\u015f \u0131\u015f\u0131\u011f\u0131n\u0131 engelleyerek g\u00fcnd\u00fczleri serinletiyor, buna kar\u015f\u0131l\u0131k \u0131s\u0131y\u0131 hapsederek geceleri s\u0131cak tutuyor. <\/p>\n
Bickel, “Ba\u015fka bir gezegende hareket eden toz girdaplar\u0131n\u0131 g\u00f6zlemleyip izleyebilmemiz inan\u0131lmaz.

S\u00f6z konusu kaymalar, ara\u015ft\u0131rma ekibine girdab\u0131n y\u00f6n\u00fcn\u00fc ve h\u0131z\u0131n\u0131 takip etme imk\u00e2n\u0131 sundu. <\/p>\n
ESA\u2019n\u0131n her iki g\u00f6revinden de sorumlu proje bilimcisi Colin Wilson, “Mars Express ve ExoMars ara\u00e7lar\u0131n\u0131n bu kadar beklenmedik ara\u015ft\u0131rmalar i\u00e7in kullan\u0131ld\u0131\u011f\u0131n\u0131 g\u00f6rmek harika.

Fakatncak y\u00fcksek h\u0131zlar\u0131na ra\u011fmen, Mars atmosferinin D\u00fcnya\u2019dakinden 100 kat daha seyrek olmas\u0131 nedeniyle, bu r\u00fczgarlar bir insan\u0131n \u00fczerinde yaln\u0131zca hafif bir esinti etkisi yarat\u0131r. <\/p>\n

Toz, Mars g\u00f6revleri i\u00e7in ba\u015fl\u0131ca risklerden biri olmaya devam ediyor. 2019\u2019da gezegeni saran k\u00fcresel bir toz f\u0131rt\u0131nas\u0131 Opportunity ke\u015fif arac\u0131n\u0131n g\u00f6revini sonland\u0131rm\u0131\u015f, 2022\u2019de de g\u00fcne\u015f panellerinde biriken toz, InSight arac\u0131n\u0131n kapanmas\u0131na neden olmu\u015ftu. <\/p>\n
Ancak toz \u015feytanlar\u0131 zaman zaman faydal\u0131 da olabiliyor; 2009\u2019da bir tanesi Spirit arac\u0131n\u0131n g\u00fcne\u015f panellerini temizlemi\u015fti. <\/p>\n
