<prompt> Pfupisa nyaya yacho: CNN Chikepe chemuchadenga cheNASA chinonzi Dawn chine saizi yetrailer chichasvika kuCeres neChishanu, chichisvika pedyo zvakakwana kuti chiiswe muchadenga uye kupedza basa rokutanga kupuraneti duku. Ndiri kufara kuti Dawn yava pamusuo weCeres, akadaro Jim Green, mutungamiriri wesangano reNASA rinoona nezvemapuraneti pamusangano wenhau musi weMuvhuro. Dawn inotarisirwa kutanga kutenderera Ceres panenge pa7:20 a.m. ET, asi NASA inoti zvingatora awa imwe kana maviri kuti tizvizive. Ceres yakawanwa muna 1801 Pluto haina kuwanwa kutozosvikira muna 1930 uye yakanga iri chinhu chokutanga chakawanwa mubhanhire guru renyeredzi duku rezuva redu pakati peMars neJupiter. Inenge mamaira mamiriyoni 310 kubva paNyika uye yakatanga kunzi ipuraneti, ndokuzodzikiswa kuva asteroid, chete kuti inzi ipuraneti duku zvakare. Mifananidzo yapakuvamba inobva kuDawn yakatoita kuti masayendisiti ebasa racho afare. Ceres akatishamisa chaizvoizvo, akadaro Carol Raymond, mutevedzeri womutsvakurudzi mukuru weDawn. Mifananidzo yokutanga yakabudisa zvimwe zvinhu zvisinganzwisisiki chaizvoizvo. Chimwe chezvinetso - mavara machena anopenya akaoneka mumifananidzo yakatorwa neDawn muna February. Zvinzvimbo izvi zvakashamisa zvikuru boka racho, uye zvave zvichishamisa boka racho navose vakazviona. Mavara acho ari mugomba rakakura makiromita 92. Nzvimbo iri pakati pemupata inenge inopenya zvakapetwa kaviri kupfuura nzvimbo iri parutivi pemupata. Kujeka kwakanyanyisa uku kwakanga kusingatarisirwi chaizvoizvo, Raymond akadaro. Boka reDawn rakanyatsonakidzwa chaizvo nechinhu ichi nokuti chakasiyana nezvimwe zvose zviri muzuva. Raymond anoti kupenya kwacho kunowirirana nezvinhu zvinoratidza zvikuru zvakaita seaizi kana kuti munyu. Izvi zvingabatsira kuwedzera kuvimbika pane zvakawanikwa muna 2014 neESAs Herschel infrared space observatory. Teresikopu yacho yakaona mhute yemvura yakapoteredza Ceres ichibva munzvimbo imwe cheteyo umo mavara acho ari. Raymond akati, Zvingangova zvine chokuita nokuparadzirwa kwemhute iyoyo yemvura. Masayendisiti eHerschel akataurawo kuti kunzvera kwavo kwakaratidza kuti Ceres ine mhepo yakapoteredza. Raymond akati boka rake rinoda...  <response>: Chikepe chomuchadenga cheNASA chinonzi Dawn chinosvika paCeres Chishanu. Ngarava yomuchadenga ndiyo yokutanga kushanyira nyika duku.
