Pemvura Mars chinotonyanya ngozi pane tinofunga

Paakatuma chitundumusere-musere kuna Mars, chinofanira sterilized kwazvo kuti tsaona, haana kutora upenyu panyika. Pashure pezvose, hapana anoda isva pechiso Red Planet nevagari Earth anogona kuita buri zvenhema munguva yemberi.

Hasha Vezvenhau pemvura Mars

Zvisinei, masayendisiti ari kudzidza itsva inoita unonakidza zano. Dzhennifer Uodsvort uye Charlz Kokell University of Edinburgh vanoti kunyange kana kusvibiswa kwakadaro kunoitika, pose Mars, pfungwa, haabvumiri chero masero vapone. Izvi zvinoratidza kuti kusvibiswa chitundumuseremusere chakasvitsa angasava dambudziko guru kudaro.

Chii perchlorate

Pakudzidza, vaongorori vakawana kuti pamusoro pemvura Mars chezuva anogona Activate remubatanidzwa inonzi perchlorate. In yezviri mamiriro, remubatanidzwa iri ngozi utachiona, uye zviri zvikuru kuMars. Kare zvaifungwa kuti perchlorate iri kusashanda nokuda nokupisa, uye sezvo Mars unotonhora chaizvo, izvi hazvifaniri kuva kutya.

"Kare, masayendisiti akafunga kuti perchlorate haagoni kusashanda mu Martian ezvinhu - Wadsworth akati bvunzurudzo yebasa IFLScience. - Kana tichida kuziva upenyu pamusoro Mars, tinofanira ngaafunge izvi ".

tsvakurudzo rabhoritari

Masayendisiti akaita zvavanotaura simulated Martian ezvinhu murabhoritari. Kushandisa Pepa anaerobic mukamuri umo hapana okisijeni, vari patsva urefu chezuva mafungu pamusoro pechiso Mars. masayendisiti zvino kuongororwa nezvaizoitwa perchlorate ari mamiriro ichi, yose hutachiona yakawanikwa pamusoro spaceship Bacillus subtilis.

Mamiriro ezvinhu akafanana Mars, masero akafa mukati maminitsi mashoma pasi mamiriro activation perchlorates. Izvi zvinoratidza kuti pemvura Mars chinotonyanya chepfu kuupenyu pane masayendisiti kare akafunga.

"Tichiri handizivi zvakawanda pamusoro zvinouraya ezvinhu enyika Martian kwezvakatipoteredza - Wadsworth akati. - Zvichida, chinonyanya dambudziko zvichava upenyu mukuru okuyerera ionizing mwaranzi, izvo chinopinda kuburikidza dzakaonda mhepo uye kunosvika pechiso Red Planet. Uyezve, zvidzidzo zvedu dzinoratidza kuti vamwe mamorekuru pamusoro pechiso kunogona zvikuru chepfu. "

Mbereko kuti chitundumusere-musere

Tichidzokera kumavambo yedu kukurukura, zvinoreva kuti hatifaniri kunetseka pamusoro mbereko kuti chitundumusere-musere vanotumwa Mars? Zvino masayendisiti kunyange mukana kuongorora dzimwe nzvimbo nyika, anozivikanwa somunhu nzvimbo inokosha, nekuti havana hwokugadzira mukana kuti chenesa chitundumusere-musere refu zvakakwana pamwero kudzivisa mukana wokutapukirwa.

Hazvisi nyore. The masayendisiti uyo aidzidzisa, akaona kuti vamwe upenyu siyana, anonzi extremophiles vanogona kurarama mumamiriro ezvinhu akaipisisa. Utachiona kuti vakaedzwa kudzidza vakanga vasiri extremophiles. Saka, masayendisiti achiri handizivi kana extremophiles vanogona kurarama pamusoro Martian pamusoro.

"Zvakakosha kuramba kutora matanho zvose varege kusvibisa Mars - masayendisiti vanoti. - Tinofanira kutora matanho sezvo vazhinji disinfect maturusi zvose kunyange munyika kuti nokuparura chitundumusere-musere ".

Where kutsvaka Martian upenyu

Sezvo kune Martian upenyu, usaora mwoyo. Kunyange hazvingaiti kuti chero upenyu - microbial kana dzimwe - vachakwanisa kurarama pamusoro Martian pamusoro, upenyu pevhu achiri sokuti somunhu mukana wakanaka. Apo zvipenyu zvinogona kudzivirirwa kwete bedzi nemwaranzi asiwo basa perchlorates.

Masayendisiti haasati kuziva sei kure anogona kupindira perchlorates. Asi kunenge kuti mashoma metres pazasi penyika upenyu zvinogona kuvapo. More mashoko achava kuwanikwa muna 2021, apo kuchera midziyo ExoMars European pakupedzisira akabata Mars. Wakakwanisa sterilized, Chokwadi.
