I-Mars kuyingozi ngisho kakhulu kunalokhu ebesikucabanga

Lapho ethumela mkhathi-Mars, uye esaphukileyo inzalo yengozi, akazange athathe ukuphila emhlabeni. Phela, akekho ofuna uNkulunkulu kungcolise ebusweni Iplanethi Ebomvu nabakhileyo eMhlabeni angenza ukuvulwa zamanga esikhathini esizayo.

abezindaba Aggressive yeplanethi i-Mars

Nokho, ososayensi e-isifundo esisha kwenza isiphakamiso ethakazelisayo. Dzhennifer Uodsvort futhi Charlz Kokell University of Edinburgh bathi ngisho noma kwenzeka ukungcoliswa ezinjalo, yeplanethi i-Mars, isimiso, ayivumeli iyiphi amaseli ukusinda. Lokhu kusikisela ukuthi ukungcoliswa mkhathi hhayi kungaba inkinga enkulu.

Kuyini perchlorate

Ekutadisheni kwabo, abacwaningi bathola ukuthi ku yeplanethi i-Mars imisebe yelanga ingabangela kusebenze ekhuthaza ngokuthi perchlorate. In the state asebenzayo, lokhu kwakwakhe kuyingozi ngoba ama-bacterium, futhi lungaphezu kakhulu kuyi-Mars. Ngaphambili kwakucatshangwa ukuthi perchlorate ivuswe ngu ukushisa, futhi njengoba i-Mars kubanda kakhulu, lokhu akufanele kube esabe.

"Ngaphambili, Ososayensi babecabanga ukuthi perchlorate akukwazi ukusetshenziswa ezimweni Mars - Wadsworth uthe IFLScience interview. - Uma sifuna ukuthola ukuphila on Mars, kumelwe sithathe le-akhawunti ".

zocwaningo laboratory

Ososayensi wenza ziphetho eyenziwe imvelo Mars egunjini lokucwaninga esibhedlela. Ukusebenzisa i-chamber anaerobic lapho kungekho i-oksijini, basuke kabusha amagagasi obuphelele kwelanga ku yeplanethi i-Mars. ososayensi bese kugadwa umphumela perchlorate kulesi sifundazwe, ukungcola okuphelele okutholakele kwi subtilis mkhathi Bacillus.

Imibandela efana Mars, amaseli bafa ingakapheli imizuzu embalwa ngaphansi isimo ukusebenza perchlorates. Lokhu kubonisa ukuthi yeplanethi i-Mars kuyinto anobuthi nakakhulu ekuphileni kunalokho ososayensi ababekucabanga.

"Asazi namanje bazi konke ngama-izimo olubulalayo imvelo Mars - wathi Wadsworth. - Mhlawumbe, inselele enkulu kuyoba ngenxa yokuphila a ecucuza imisebe eyingozi ionizing, okuyinto lingena ngokusebenzisa nomoya omncane womkhathi futhi ifinyelela ebusweni Iplanethi Ebomvu. Ngaphezu kwalokho, ucwaningo zethu zingabonisa ukuthi abanye yezinhlayiya phezu kungaba zibe nobuthi obuyingozi kakhulu. "

Inzalo Mkhathi

Ukubuyela ekuqaleni ingxoxo yethu, ingabe lokho kusho ukuthi akufanele sikhathazeke ngokuthi inzalo mkhathi ukuthi ithunyelwa Mars? Manje ososayensi musa ngisho nethuba ukuhlola ezinye izindawo iplanethi, eyaziwa ngokuthi indawo ekhethekile, ngoba akukho kungenzeka lobuchwepheshe abilayo mkhathi ezingeni ngokwanele okusezingeni eliphezulu ukugwema ingozi yokutheleleka.

Akukona ngakho elula. Ososayensi owenza lokhu kuhlola, waphawula ukuthi abanye izinto eziphilayo, okuthiwa extremophiles kungaba siphila ezimweni ezimbi kakhulu. Igciwane wahlolwa isifundo kwakungafanele extremophiles. Ngenxa yalokho, ososayensi namanje angazi extremophiles angaphila kuyi-Mars.

"Kubalulekile ukuba siqhubeke bathathe zonke izinyathelo hhayi ukungcolisa Mars - ososayensi bathi. - Kufanele bathathe izinyathelo njengoba abaningi ukuba zibulale bonke amathuluzi ngisho emhlabeni ukuqalisa mkhathi ".

Kuphi ufune ukuphila Mars

Njengoba ukuphila Mars, ungadumali. Nakuba kungenakwenzeka ukuthi iyiphi ukuphila - microbial noma enye - bazokwazi ukusinda kuyi-Mars, ukuphila komhlaba namanje kubonakala sengathi yithuba elihle. Lapho izinto eziphilayo ingavikelwa hhayi kuphela bemisebe kodwa nangokuzama perchlorates asebenzayo.

Ososayensi okwamanje sati kutsi sikhashane kangakanani akwazi ukungena perchlorates. Kodwa kungenzeka ukuthi a amamitha ambalwa ngaphansi kwamanzi ekuphileni angaba khona. Olunye ulwazi izotholakala 2021, lapho imishini apharathasi ExoMars European ekugcineni wathinta Mars. Engingakusho inzalo, yebo.
