<prompt> Pfupisa nyaya yacho: CNN Masayendisiti epaNASA ava pedyo zvikuru nokunzwisisa kuti mvura yakawanda zvakadini ingadai yakavapo paMars yapakuvamba. Izvi zvitsva zvakawanikwa zvinoratidzawo kuti matura emvura ekare ikoko angave akavapo sei kwemabhiriyoni emakore, zvichiratidza kuti makungwa ekare ePuraneti Dzvuku angave akabata mvura yakawanda kupfuura Arctic Ocean yePasi, masayendisiti eNASA anoratidza mufundo yakabudiswa Chishanu mumagazini yeScience. Geronimo Villanueva, musayendisiti weNASAs Goddard Space Flight Center akati, Kutsvakurudza kwatakaita kunotibatsira kuziva kuti Mars yakambova nemvura yakawanda zvakadini, nokuona kuti yakarasika zvakadini muchadenga. Nebasa iri, tinogona kunzwisisa zviri nani nhoroondo yemvura paMars. Kuti vawane mhinduro yemubvunzo uyu wekare pamusoro pemamolekyumu emvura ari paMars, masayendisiti akashandisa materesikopu matatu makuru epasi pose ari kuChile neHawaii, kuti aone mvura iri mumhepo yepasi pano munzvimbo dzakasiyana-siyana uye mumwaka wakasiyana-siyana, kubva muna March 2008 kusvika muna January 2014. Kubva pasi, taigona kutora mufananidzo wehemisphere yose muhusiku humwe chete, akadaro Michael Mumma weGoddard. Masayendisiti akatarisa mwero wemhando mbiri dzakasiyana - kana kuti isotopes - dzemvura, H2O uye HDO. Iyi yokupedzisira inoitwa kuti ive inorema neimwe yeatomu dzayo dzehydrogen, inonzi deuterium, iyo ine neutron mukati mayo mukuwedzera kuproton iyo maatomu ose ehydrogen ane. Izvozvo zvakaremedza HDO zvikuru, nepo huwandu hukuru hwehydrogen hunobva muH2O hwakabhururukira mumhepo, hwakaparadzana nechisimba chakaderera cheMars ndokunyangarika muchadenga. Somugumisiro, mvura yakabatwa mumakomo echando eMars ine mwero wakakwirira zvikuru weHDO kupfuura mvura inoyerera paPasi, vakadaro masayendisiti. Masayendisiti akaenzanisa chiyero cheH2O neHDO mumhepo yakapoteredza Mars nhasi nechiyero chemamorekuru maviri akabatwa mukati memeteorite yeMars, ibwe rakatyoka kubva kuMars - zvichida apo asteroid yakarova - ndokuburukira paPasi makore anenge mabhiriyoni 4.5 apfuura. Vakakwanisa kuziva kuti chiyero ichocho chakanga chachinja zvakadini nokufamba kwenguva uye kufungidzira kuti mvura yakawanda zvakadini yakanga yanyangarika paMars - inenge 87. Zvakawanikwa zvinoratidza kuti...  <response>: Masayendisiti akadzidza mvura iri mumhepo yakapoteredza Mars neteresikopu huru nhatu dzechiedza chisina kutsvuka. Vakaenzanisa uwandu hwemamwe mamorekuru epasi neaya emumeteorite yakabva kuMars yakamhara paPasi.
