Pfupisa nyaya yacho:  Puraneti tsvuku inogona kuva ichine mvura yakasviba, inoratidza mashoko akaunganidzwa neCuriosity rover yeNASA. Vanzveri vave vachiziva kwenguva refu kuti pane mvura muchimiro cheaizi paMars. Zvino, mashoko matsva anobva kumotokari yokuMars inonzi Curiosity, akabudiswa mumagazini inonzi Nature, anoratidza kuti kunobvira kuti pane mvura yakasviba pedyo nepasi repuraneti tsvuku. "Mupata Wakavanzwa" uri muGale Crater paMars. Matombo ane tsanga duku zvikuru, ayo akadonha zvishoma nezvishoma mumvura, akaiswa pasi chaipo penyanza yomupata. Mapepa etsvina ari pasi akatsiga, naizvozvo chinhu chiri chose chinoratidza kuti Gale Crater yose zvayo ingave yakanga iri nyanza huru. Mashoko matsva anobva kuNASA's Mars rover Curiosity, akabudiswa mumagazini inonzi Nature, anoratidza kuti zvinobvira kuti pane mvura yakasviba pedyo nepasi repasi dzvuku. Tsananguro yacho ndeyokuti chinhu chinonzi perchlorate chakawanikwa muvhu, icho chinoderedza nzvimbo inotonhora zvokuti mvura haitonhori kuva chando, asi iri mvura uye iripo mumvura ine munyu zvikuru. Curiosity yakaona munyu unonzi perchlorates, unogona kutora mvura iri mumhepo yomudenga ndokuishandura kuva mvura ine munyu. Usiku pahunosvika, imwe mhute yemvura iri mumhepo yakapoteredza nyika inoita chando, asi calcium perchlorate inonyorovesa zvikuru uye inoumba munyu nemvura, nokudaro nzvimbo inotonhora inoderedzwa uye chando chinogona kuchinja kuva chinwiwa. Curiosity yakamhara paMars muna 2012 mumupata mukuru, Gale, uri kumaodzanyemba kweequator. Gomo guru racho rakareba makiromita 154 uye kumucheto kwaro kwakareba makiromita anenge mashanu. Pakati pemupata wacho pane gomo rinonzi Mount Sharp. Curiosity yakafamba makiromita anopfuura 10 kubva panzvimbo yakadzika ichienda kuMount Sharp uye yakaita zvidzidzo zvakawanda munzira. Chiremba Morten Bo Madsen, purofesa anobetsera uye mutungamiriri weMars Group paNiels Bohr Institute paUniversity of Copenhagen muDenmark, akati: 'Takawana chinhu chinonzi calcium perchlorate muvhu uye, mumamiriro ezvinhu akakodzera, icho...
Zvinobvira kuti pane mvura yakasvibirira iri pedyo nepasi penyika tsvuku. Chinhu chinonzi perchlorate chakawanikwa muvhu, icho chinoderedza nzvimbo inotonhora zvokuti mvura haitonhori kuita chando, asi inenge iri mvura. Upenyu sezvatinohuziva 'hazvibviri' kuti huvepo nemhaka yemamiriro ezvinhu akaoma epasi. Kuwana kunogona kuita kuti zvive nyore kuti vanhu vagare paMars munguva yemberi.
