<prompt> Fingqa isihloko: Ubufakazi bokuthi iMars yake yakwazi ukuhlala abantu bukhula njalo, njengoba amasampula aqoqwe i-Mars Curiosity rover ye-NASA embule isithako esiyinhloko sokuphila emadwaleni aseMars. Ososayensi bathola iminonjana yezinhlanganisela ze-nitrogen ezaziwa ngokuthi ama-nitrate, umthombo obalulekile wezakhamzimba zezinto eziphilayo eMhlabeni. Lokhu okutholakele kuyisihluthulelo sakamuva emcabangweni wokuthi nakuba iMars ingenalutho futhi yomile manje, yake yakwazi ukuhlala abantu. Ososayensi beNASA eCalifornia bathola ubufakazi be-nitrogen eMars. Okutholakale kwenziwa yi-Curiositys eboniswe lapha Sample Analysis at Mars instrument. Ososayensi bathola ama-nitrate - umthombo we-nitrogen wokuphila eMhlabeni. Cishe lenziwa ukushayeka kwe-asteroid noma umbani emvuleni. Lokhu okutholakele kwanyatheliswa ephephabhukwini i-Proceedings of the National Academy of Sciences. Ephepheni labo, iqembu labacwaningi lathi i-nitrogen ingase ibonise isigaba sokuqala somjikelezo we-nitrogen yasendulo ebusweni beMars yasendulo. Lokhu kwakungase kunikeze umthombo we-nitrogen ofinyeleleka ngokwemvelo ukuze kube nokuphila eMars. Umkhathi womhlaba ocebile nge-nitrogen wenza kwaba nokuphila, kodwa umsuka womoya esiwuphefumulayo kade waba imfihlakalo. Manje, ososayensi bakholelwa ukuthi bayitholile impendulo: ukuthi amandla ama-tectonic abhekene nokwakhiwa kwezintaba-mlilo nezintaba-mlilo, nawo enza umkhathi waba owakhayo. Izazi zesayensi yomhlaba zacwaninga ngamakhemikhali ama - tectonic futhi zathola ukuthi i - nitrogen yaqala ukwakheka emkhathini woMhlaba eminyakeni eyizigidi eziyizinkulungwane ezintathu edlule. Lapho bebhala kumagazini i-Nature Geoscience, abacwaningi baseCarnegie Institution yaseWashington bachaza ngo-October 2014 ukuthi ukwakheka kwamakhemikhali emoyeni esiwuphefumulayo kuwumphumela weminyaka eyizigidigidi yokuhlanganiswa kwezakhi zofuzo, kanye nomsebenzi wamazwe. Nakuba ososayensi babekwazi ukuthi izitshalo ziyakwazi ukwakha umoya-mpilo, owenza ingxenye eyodwa kwezinhlanu yomkhathi womhlaba, okuqukethwe i-nitrogen - eyenza amaphesenti angu - 80 omoya - kwakuyimfihlakalo. Ukutholakala kwe-nitrogen yaseMars emvelweni weMars kunemithelela ebalulekile ekuhlaleni kanye...  <response>: Ososayensi beNASA eCalifornia bathola ubufakazi be-nitrogen eMars. Lokhu kutholakala kuyi - Curiositys Sample Analysis at Mars instrument. Ososayensi bathola ama-nitrate - umthombo we-nitrogen wokuphila eMhlabeni. Cishe lenziwa ukushayeka kwe-asteroid noma umbani emvuleni. Lokhu kwandisa ubufakazi bokuthi iplanethi ebomvu yake yahlalwa esikhathini esidlule.
