<prompt> Fingqa isihloko: CNN Umkhumbi-mkhathi we-NASA i-Dawn osayizi wetrektara-trailer uzosondela kuCeres ngoLwesihlanu, usondele ngokwanele ukuba udonswe emzileni futhi uqedele umsebenzi wokuqala wokuya eplanethini elincane. Ngiyajabula nje ukuthi iDawn manje isisemnyango kaCeres, kusho uJim Green, umqondisi we-NASAs planetary science division engqungqutheleni yabezindaba ngoMsombuluko. UDawn kulindeleke ukuba aqale ukuzungeza iCeres cishe ngo-7:20 ekuseni. I-ET, kodwa i-NASA ithi kungase kuthathe ihora noma amabili ukuyiqinisekisa. I-Ceres yatholakala ngo-1801 i-Pluto yatholakala ngo-1930 futhi yaba into yokuqala eyatholakala ebhande lezinkanyezi ezincane eliphakathi kweMars neJupiter. Cishe iqhele ngamamayela ayizigidi ezingu-310 eMhlabeni futhi ekuqaleni yayihlukaniswa njengeplanethi, kamuva yehliselwa esikhundleni sokuba i-asteroid, ukuze iphinde ihlukaniswe kabusha njengeplanethi encane. Izithombe zokuqala ezivela kuDawn sezivele zenza ososayensi bomsebenzi babe nesasasa. UCeres usimangaze ngempela, kusho uCarol Raymond, isekela lomcwaningi oyinhloko weDawn. Izithombe zokuqala ziye zaveza izici eziyimfihlakalo ngempela. Enye yezimfumbe - amachashaza amabili amhlophe akhanyayo avele ezithombeni ezithathwe iDawn ngoFebhuwari. Lezi zindawo zazimangaza kakhulu iqembu, futhi ziye zaba yisimanga eqenjini nakubo bonke abaye bazibona. La mabala asemgodini ongamakhilomitha angu-92 ububanzi. Iphuzu elisenkabeni yomgodi likhanya ngokuphindwe kabili kuneliphuzu eliseceleni komgodi. URaymond wathi: Lokhu kukhanya okukhulu kwakungalindelekile ngempela. Ithimba leDawn lichichima injabulo ngempela ngalesi sici ngoba siyingqayizivele esimisweni sonozungezilanga. URaymond uthi lokhu kukhanya kuvumelana nezinto ezibonakalisa kakhulu njengeqhwa noma usawoti. Lokhu kungase kusize ukwengeza ukwethenjwa kokutholakala okwenziwa ngo-2014 yi-Herschel infrared space observatory ye-ESA. Isibonakude sathola umusi wamanzi ozungeze iCeres uvela endaweni efanayo lapho kutholakala khona amabala. URaymond wathi: Kungase kuhlobane nokukhishwa komhwamuko wamanzi. Ososayensi baseHerschel bathi ucwaningo lwabo lubonisa ukuthi iCeres inomoya-mpilo. URaymond uthe ithimba lakhe liyafisa...  <response>: Umkhumbi-mkhathi i-Dawn we-NASA ufika ngoLwesihlanu eCeres. Lesi sikebhe singesokuqala ukuvakashela iplanethi encane.
