Fursada rover-ka ayaa sahaminaysay meeraha cas tan iyo 2004tii mana jirin wax shuruudo ah oo aysan awoodin inay sii wadato hawlaheeda. Si kastaba ha ahaatee, sanadkii 2018, duufaan bacaad ah ayaa ku dhufatay dusha sare ee meeraha, taas oo keentay dhimashada qalabka farsamada. Boodhku waxay u badan tahay inay si buuxda u dabooshay baalayaasha qoraxda ee Fursada, taasoo keentay lumis koronto. Si kastaba ha ahaatee, bishii Febraayo 2019, hay'adda hawada sare ee Maraykanka ee NASA ayaa ku dhawaaqday inuu dhintay. Hadda saynisyahannadu waxay sheegeen in biyaha si la mid ah looga saari karay dusha sare ee Mars. Gabagabadaan waxaa gaaray cilmi-baarayaal NASA oo aqoon u leh xogta laga helay Trace Gas Orbiter (TGO).
Cilmi-baadhayaashu waxay rumaysan yihiin in waagii hore, Mars ay lahayd jawi cufan oo ku dhow 20% oogada meeraha ayaa lagu daboolay biyo dareere ah. Qiyaastii 4 bilyan oo sano ka hor, meeraha cas ayaa lumiyay dhul-goosadeedka birlabeedka, ka dib waxaa daciifay difaacii uu ka ilaalin jiray dabaysha cadceedda wax burburisa, taasoo keentay in inta badan jawigiisii uu lumo.
Nidaamyadani waxay ka dhigeen biyaha dushiisa meeraha kuwo nugul. Xogta laga helay indha-indhaynta TGO waxay muujinaysaa in duufaannada siigada ay sabab u yihiin waayitaanka biyaha meeraha Cas. Waqtiyada caadiga ah, qaybo ka mid ah biyaha hawadu waxay u jiraan 20 km oogada meeraha, halka intii lagu jiray duufaantii boodhka ah ee dishay Fursad, TGO waxay ogaatay molecules biyaha oo joogsanaya 80 km. Sarrayntan, molecules biyuhu waxay u kala baxaan hydrogen iyo oxygen, oo ay ka buuxaan qaybo cadceedda ah. Joogitaanka lakabyada sare ee jawiga, biyuhu waxay noqonayaan kuwo aad u fudud, taas oo gacan ka geysan karta ka saarista oogada Mars.
