Pamwamba pa Mars ndi woopsa kwambiri kuposa momwe ife tikuganizira

Pamene akutumiza spacecraft kuti Mars, izo ziyenera kukhala bwinobwino chosawilitsidwa ngozi, iye sanali kutenga moyo padziko lapansi. Ndipotu palibe munthu amene amafuna kusokoneza padziko Red Planet ndi anthu okhala padziko lapansi akhoza kupanga kutsegula onyenga m'tsogolo.

media Modzikhulupirira padziko Mars

Komabe, asayansi phunziro latsopano lachititsa mfundo zochititsa chidwi. Dzhennifer Uodsvort ndi Charlz Kokell University of Edinburgh kuti ngakhale poizoni ameneyu zikachitika, pamwamba pa Mars, mfundo salola maselo aliyense apulumuke. Zimenezi zikusonyeza kuti kuipitsidwa kwa spacecraft akhoza kukhala ngati vuto lalikulu.

perchlorate Kodi

Mu ku phunzira kwao, akatswiri anapeza kuti padziko Mars dzuwa yambitsa pawiri otchedwa perchlorate. Mu boma yogwira pawiri izi ndi owopsa kwa mabakiteriya, ndipo kwambiri pa Mars. Poyamba ankaganiza kuti perchlorate ndi adamulowetsa ndi kutentha, ndipo monga Mars ndi ozizira kwambiri, siziyenera mantha.

"Poyamba, asayansi ankaganiza kuti perchlorate sangathe adamulowetsa zinthu Martian - Wadsworth anati mu kuyankhulana IFLScience. - Ngati tikufuna kudziwa moyo pa Mars, tiyenera zimenezo ".

kafukufuku zasayansi

Asayansi anapanga apeza yoyerekeza chilengedwe Martian zasayansi. Ntchito m'chipinda anaerobic imene palibe mpweya, iwo reconstituted mafunde kutalika dzuwa padziko Mars. Asayansi ndiye kuunikira mmene perchlorate mu chikhalidwe ichi, kuipitsidwa okwana anapezeka pa subtilis m'mlengalenga Bacillus.

Zinthu zofanana ndi Mars, maselo anamwalira pasanathe mphindi zochepa pansi chikhalidwe cha perchlorates kutsegula. Izi zikusonyeza kuti padziko Mars kuli ngakhale poizoni moyo kuposa asayansi ankaganizira poyamba.

"Ife sitikudziwa zambiri zokhudza zinthu zakupha chilengedwe Martian - Wadsworth anati. - Mwina vuto lalikulu adzakhala moyo wa kamwazi wa poizoni ionizing, amene likulowerera kudzera m'mlengalenga woonda nufikira padziko Red Planet. Kuwonjezera apo, kafukufuku wathu akusonyeza kuti ena mamolekyulu padziko kungakhale kwambiri poizoni. "

Yolera yotseketsa wa Spacecraft

Kubwerera ku chiyambi cha kucheza kwathu, kodi zikutanthauza kuti sitiyenera kudandaula za njira yolera yotseketsa wa spacecraft wotumidwa kwa Mars? Tsopano asayansi ngakhale mwayi kufufuza madera ena a dziko, lotchedwa pamalo padela kwambiri, chifukwa iwo alibe kuthekera luso samatenthetsa spacecraft kwa mkulu mlingo zokwanira kupewa kutenga matenda.

Ndi osiyanasiyana. Asayansi amene anachita kafukufukuyu, ananena kuti anthu ena zamoyo, wotchedwa extremophiles kupulumuka mu kwambiri zinthu. Mabakiteriya amene anayesedwa kuphunzira sanali extremophiles. Choncho, asayansi sindikudziwa ngati extremophiles kupulumuka padziko Martian.

"Nkofunika kupitiriza kusamala onse kuti kuipitsanso Mars - asayansi amati. - Tiyenera kusamalitsa ambiri mankhwala zipangizo zonse ngakhale mu dziko kukhazikitsa spacecraft ".

Kodi kuyang'ana moyo Martian

Monga ku moyo Martian, musakhumudwe. Ngakhale ndi chodziwikiratu kuti moyo uliwonse - tizilombo tating'onoting'ono kapena ena - adzakhala ndi moyo padziko Martian, moyo mobisa komabe zikuwoneka ngati mwayi wabwino. Kodi zamoyo angatetezedwe osati ndi cheza komanso perchlorates yogwira.

Asayansi simumamudziwa momwe amatha kulowa perchlorates. Koma zikuoneka kuti mamita angapo pansi pa moyo pakhale. Zambiri lidzakhala lilipo mchaka cha 2021, pamene pobowola zida ExoMars European potsiriza anakhudza Mars. Wokwanira chosawilitsidwa, kumene.
