<prompt> Bheka isigaba esingezansi bese uphendula umbuzo emva kwalokho ngolimi olufanayo nesigaba: I-Passage: Ukutholwa kweCassini e-Enceladus kuye kwaholela ezifundweni eziqondene nemishini yokulandelela, kufaka phakathi i-probe flyby Uhambo oluya e-Enceladus naseTitan noma i-JET ukuhlaziya okuqukethwe yi-plume in-situ, i-lander yi-German Aerospace Center ukutadisha amandla okuhlala olwandle lwayo olungaphansi komhlaba i-Enceladus Explorer, kanye nemibono emibili yemishini eqondiswe ku-astrobiology i-Enceladus Life Finder kanye ne-Life Investigation For Enceladus LIFE. I-European Space Agency ESA yayihlola imiqondo ngo-2008 ukuthumela i-probe ku-Enceladus ohambweni oluzohlanganiswa nezifundo zeTitan: Titan Saturn System Mission SMTS. I-TSSM kwakuyisiphakamiso esihlangene se-NASA ESA sokuhlola izinyanga zikaSaturn, ngokugxila ku-Enceladus, futhi yayincintisana nesiphakamiso se-Europa Jupiter System Mission EJSM sokuxhaswa ngezimali. NgoFebhuwari 2009, kwamenyezelwa ukuthi i-NASA ESA inikeze umsebenzi we-EJSM kuqala kune-TSSM, yize i-TSSM izoqhubeka nokufundwa nokuhlolwa. Umbuzo: Yimuphi umsebenzi owawubaluleke kakhulu ku - NASA?  <response>: umsebenzi we-EJSM
