NASA yasanze udukoko two ku Isi dushobora kubaho mu bicucu by’Ukwezi
Ubushakashatsi bwa NASA bwasohotse muri Science Advances bugaragaza ko bagiteri na fungi bikomoka ku ruhu rw’abantu bishobora kubaho nibura umunsi umwe mu duce tw’ubukonje n’igicucu ku majyepfo y’Ukwezi.
Ukwezi nta kirere gufite, gutwikwa n’imirasire ikaze, kandi ubushyuhe bwaho bushobora guhinduka cyane. Kubera ibyo, byakunze gutekerezwa ko nta kinyabuzima cyakwihanganira kuhaba. Ubushakashatsi bwa NASA bwasohotse mu kinyamakuru Science Advances ku wa 19 Kanama 2026 bwerekanye ko hari uduce duto duto aho udukoko two ku Isi dushobora kwihangana.
Ahantu hangana n’ikirenge cy’umuhanga mu kirere
Abashakashatsi bagereranyije imiterere y’uduce dutatu two ku majyepfo y’Ukwezi: Nobile Rim, Connecting Ridge na de Gerlache Rim. Utwo duce ni dumwe mu dushobora kwakira ubutumwa bwa Artemis III bwa NASA buzagezayo abantu.
Basanze ahantu udukoko dushobora kubaho hatandukanye cyane mu bunini: hari ahagana n’igise cy’ikinogo kingana na kilometero nyinshi, ariko hari n’ahato cyane hangana n’ikirenge cy’umuhanga mu kirere.
Udukoko twagenzuwe
Itsinda ryakoze igerageza ku dukoko dusanzwe duboneka mu bikoresho byo mu kirere no ku ruhu rw’abantu: ifungi Aspergillus niger, bagiteri Bacillus subtilis, Staphylococcus aureus na Deinococcus radiodurans, ndetse n’amoko atandukanye ya Fusarium.
Ibipimo byakoreshejwe byubatswe ku makuru y’uburebure n’ubushyuhe yakusanyijwe n’ibyuma biri ku cyogajuru Lunar Reconnaissance Orbiter cya NASA, byiyongeraho icyitegererezo cy’uko imirasire igera ku butaka bw’Ukwezi.
Icyo ubu bushakashatsi butavuga
Aha ni ho hakwiye kwitonderwa. Abashakashatsi basobanura ko “kubaho” muri ubu bushakashatsi bisobanura ko agakoko gashobora kuguma ari kazima nibura umunsi umwe w’Isi. Ntibivuga ko gashobora gukura ngo kororoke ku Kwezi. Iryo tandukaniro ni ingenzi cyane.
Impamvu bireba ubushakashatsi bw’ubuzima
Prabal Saxena wo mu kigo cya NASA cyitwa Goddard Space Flight Center, umwanditsi wa mbere w’ubwo bushakashatsi, yavuze mu Cyongereza ati: “Humans are natural explorers, and with them come their voices, their memories … and their microbes.”
Icyo bihindura ni uko abantu bajya ku Kwezi bajyana n’udukoko twabo, bigatuma bigora abahanga gutandukanya ibiriho kuva kera n’ibyo abantu bahageze babijyanye. Undi mushakashatsi, Needham, yavuze ati: “We need to understand what was there before us, because when we go to Mars to search for signs of life beyond our planet, we will want to make sure it’s not stuff we brought.”
