I-Saturn saturn Titan icatshangelwa kahle enye yezinhlaka ezinelukuluku kulo lonke uhlelo lwelanga. Ngaphezu komhlaba, kuphela lapho kukhona umjikelezo womhlaba wonke woketshezi onolwandle namachibi aphuma emafwini bese kuthola imvula. Kuliqiniso, ebangeni elikhulu ukusuka elangeni nangokubandakanyeka, amanzi eTitanium kugcinwe kuphela njengeqhwa, futhi ama-hydrocarbons akhanyayo adlala indima ye-liquid - ikakhulukazi i-methane.
Amanzi e-liquid angajulile, ngaphansi kwamagxolo eqhwa we-titanium, ubukhulu bawo alinganiselwa kumakhilomitha ayikhulu. Lona umhlaba oyingqayizivele, futhi amandla ayo avuma ngokusobala ukuthi kukhona impilo yendawo, yize ngokungafani nezethu. Lesi sici sibonisa umsebenzi omusha muva nje kwinkomfa ye-52nd yenyanga yocwaningo namaplanethi (i-LPSC).
Ababhali bayo bayiqembu elikhulu lososayensi abavela eYurophu, eBrazil nase-USA - bakhombisa ukuthi amanzi avela ekujuleni kweTitanium okungenani kwesinye isikhathi kufanele ahlanganiswe ne-hydrocarbons ebusweni, adale imvelo enhle ye-biochemical. Lokhu kungenxa yemifantu evela ku-cortex ye-satellite ngenxa yokushayisana nokuhlanzwa kwama-comets nama-asteroid.
Abaphenyi balingise ukuxabana, okumele ngabe kuholele ekubonakaleni kwe-crater crater enkulu kunazo zonke: Menrva inamakhilomitha angama-425 kububanzi, futhi iminyaka yakhe ilinganiselwa eminyakeni eyizigidi eziyinkulungwane. Izibalo zibonisa ukuthi zingavela ngenxa yokuwa komzimba wasezulwini onobubanzi bamakhilomitha angama-34 nangejubane elingamakhilomitha ayisikhombisa ngomzuzwana. Amandla womthelela wanele ukuvela ebusweni hhayi kuphela amanzi, kodwa futhi nechibi lamanzi eliwuketshezi, eliqandisiwe ngaphezulu kweminyaka eyisigidi.
Ngokusho kwababhali bomsebenzi, kungahle kwanele ngemvelaphi yezinto zokuqala zokuqala kanye nokwethulwa kwezindlela ezinamandla zemvelo zokuziphendukela kwezinto eziphilayo. Mhlawumbe i-menrva ayisodwa kulokhu: ukubukeka kwezinye izikebhe ezinkulu kungahambisana nokushisa okufanayo nokuvusa amanzi okushisa namanzi. Ekugcineni qinisekisa lokhu kuzoba yi-mission yesikhathi esizayo ye-NASA Dragonfly, okufanele iqale ngo-2027 naku-2038 ukufika eTitan.
