Amanzi awuketshezi ekujuleni kweRed Planet?
Ososayensi be-National Institute of Astrophysics e-Bologna, e-Italy, bathole ubufakazi bokuba khona kwamanzi awuketshezi kuyi-Mars. Ichibi eligcwele kufanele libe cishe i-1,5 km ngaphansi kobuso beplanethi. Ukutholwa kwenziwe ngokusekelwe kudatha evela kuthuluzi le-radar ye-Marsis ezungeza i-European Space Agency (ESA) njengengxenye yemishini ye-Mars Express.
Ngokusho kwezincwadi zososayensi "eNauka", eduze nendawo eseningizimu ye-Mars kufanele kube nechibi elikhulu likasawoti. Uma imibiko yososayensi iqinisekiswa, lokhu kungaba ukutholwa kokuqala kwamanzi awuketshezi kwi-Red Planet kanye nesinyathelo esikhulu ekunqumeni ukuthi kukhona ukuphila kuwo.
“Cishe yichibi elincane,” kubhala uProf. Roberto Orosei weNational Astrophysical Institute. Ithimba alikwazanga ukunquma ukujiya kongqimba lwamanzi, lithatha kuphela ukuthi okungenani bekuyimitha elingu-1.
Abanye abacwaningi bayakungabaza lokhu kutholakala, bakholelwa ukuthi kudingeka ubufakazi obengeziwe ukuze kuqinisekiswe imibiko yososayensi base-Italy. Ngaphezu kwalokho, abaningi bayaqaphela ukuthi ukuze ahlale ewuketshezi emazingeni okushisa aphansi kangaka (alinganiselwa ku-10 kuya ku-30 °C), amanzi kumelwe abe nosawoti omningi, okwenza kube mancane amathuba okuba noma yiziphi izinto eziphilayo zisale kuwo.
