I-NASA ifumene izinto ezintathu zenkqubo yelanga ezinolwandle olungaphantsi.UJohn Fowler / Unsplash Isiphekepheke seNASA sifumanise ulwandlekazi olukhulu lwamanzi anetyuwa ngaphantsi komphezulu womhlaba ojikeleze umhlaba, umqondiso wokuba iplanethi inokuba yayikhe yanobomi basemzini.
Uphando lupapashwe ngoMvulo ngokusekwe kwidatha efunyenwe yiphenyo ye-Dawn ethathe umhlala-phantsi ngoku ibonise ukuba kukho indawo yokugcina amanzi ephantsi malunga neekhilomitha ezingama-25 ubunzulu kunye namakhulu eekhilomitha ububanzi nzulu ngaphantsi kweCeres, eyona nto inkulu kwibhanti ye-asteroid phakathi kweMars neJupiter.
ICeres inobubanzi obumalunga neekhilomitha ezingama-550 (950 km), malunga nesinye kwishumi elinesithathu soMhlaba. Isiphekepheke se-Dawn sajikeleza iplanethi encinci ukusuka ngo-2015 ukuya ku-2018 ngaphambi kokuphela kwepetroli. Ngokukodwa ifunde indawo eqaqambileyo kumphezulu weCeres, abathi oosonzululwazi bafumanisa kamva ukuba yayilulutho lweetyuwa ezenziwe nge sodium, icarbon, kunye neoksijini egqunywe lulwandle olungaphantsi komhlaba.
Okubaluleke ngakumbi, abaphandi bakholelwa ukuba inkqubo ye-geologic eyadala irusi enetyiwa isenzeka.
Oku kuphakamisa i-Ceres ukuba ibe kwinqanaba 'lehlabathi lolwandle', kuqatshelwe ukuba olu didi alufuni ukuba ulwandle lube lolwehlabathi, uCarol Raymond, umphenyi oyintloko we-NASA kwi-Dawn mission, uxelele iReuters.

Ulwandle olungaphantsi komhlaba lubekwe kumngxuma oziikhilomitha ezingama-57 ububanzi kumhlaba osemantla eCeres. Indawo inenye indawo eqaqambileyo njengale ifundwe zizazinzulu.
Kwimeko yaseCeres, siyayazi ukuba amanzi olwelo ngumlinganiso wengingqi kodwa asinakuqiniseka ukuba umhlaba wonke jikelele, utshilo uRaymond. Nangona kunjalo, eyona nto ibaluleke kakhulu kukuba kukho ulwelo kwizinga elikhulu.
Ngaphambi kweCeres, i-NASA yafumana ulwandle olufanayo ngaphantsi komhlaba kwi-Enceladus, inyanga enomkhenkce kaSaturn, kunye ne-Europa, inyanga enomkhenkce kaJupiter.
Amathuba okufumana ubomi kwelinye ilizwe ayaqhubeka enyuka, uMlawuli we-NASA uJim Bridenstine Ithunyelwe ngolwesibini. ICeres bubungqina bamva nje bokuba isixokelelwano sethu selanga sizaliswe ziindawo zamandulo ezazinokuhlala.
Kule veki, uphando lwe-NASA's Mars, Insight, wafumanisa ubungqina obungaphezulu ucebisa ukuba iplanethi ebomvu yayifana kakhulu noMhlaba kwaye inokuba ikhe yahlala kubomi kwakudala.
Besebenzisa i-seismometer eqhotyoshelwe kwi-Insight lander, abaphandi bakwazi ukuhlalutya ukungcangcazela okuvela kuMars ngexesha leemarsquakes kunye nokufunda ubume bangaphakathi beplanethi. Bafumene imimandla emithathu yotshintsho phakathi kwemaleko kaMars enokuthi iqulethe ulwazi oluxabisekileyo malunga nezigaba zakudala zokwakheka kweeplanethi.
Enye yayingama-22 eekhilomitha ngaphantsi komphezulu weMars, okanye malunga nomgama ofanayo nokuqala kommandla wotshintsho phakathi koqweqwe loMhlaba nengubo. Indawo yokugqibela yenguqu yayisekude kufutshane nomongo wentsimbi kaMars, onika izazinzulu ukuqonda ngokwenziwa kweeplanethi.
