Ka ili o Mars mea e oi pilikia ma mua o mākou manaʻo

I ka hoʻouna i kekahi spacecraft i Mars, ka mea, ua i e ho'ōla loa sterilized i ka ulia, la oia i lawe i ke ola ma luna o ka honua. Ma hope o nā mea a pau, i kekahi manao e contaminate i ka ili o ke Ka Kaiula, a Honua ka poʻe e noho ana e hana i kekahi puka wahaheʻe i loko o ka wā e hiki mai.

ʻano pākīkē Media ka ili o Mars

Eia naʻe,ʻepekema ma ka hou study hana i ka intriguing a'ōlelo hoʻohali. Dzhennifer Uodsvort a Charlz Kokell University o Edinburgh e olelo aku e hiki ina ia mea hoʻohaumia i, o ka ili o Mars, ma ka rula, aole ia e ae i kekahi keena ola. Ua paipai i ka mea hoʻohaumia o ka spacecraft i ole e like me ka nui pilikia.

He aha ka perchlorate

Ma ko lakou like, ka noiʻi loaʻa ia ma luna o ka ili o Mars Map ke haʻalele i ka hui i kapaia perchlorate. Ma kaʻeleu moku'āina, kēia hui mea pilikia no ka koʻohune, a me ia mea nui loa ma Mars. Mua ia i manaʻo i ke perchlorate ua ho'ā 'ia paha ma ka wela, a me Mars ka loa anu, keiaʻaʻole e makau e.

"Mua, nä känaka 'epekema, manao iho la ia perchlorate hiki ole e ho'ā' ia i loko o Martian ana - Wadsworth aku la i loko o ka ninaninau IFLScience. - Inā mākou makemake e huai ae ola ma Mars, e lawe mākou i kēia i loko o mooolelo ".

keʻena hoʻokolohua noiʻi

Nā kānakaʻepekema i kā lākou mau hopena a simulated Martian 'ia i loko o ke keʻena hoʻokolohua. E ho ohana i ka anaerobic keena ma a he mea ole oxygen, e reconstituted ka mea, lōʻihi Map ka nalu ma luna o ka ili o Mars. ʻepekema laila, ua hoʻonānā i ka hopena o ka perchlorate i loko o kēia moku'āina, ka huina o na mea hoʻohaumia i loaʻa ma luna o ka spaceship Bacillus subtilis.

Nā kūlana like ia Mars, na keena make ihola i loko o kekahi mau minuke ma lalo o keʻano o ka ho'ā hope perchlorates. Kēia Hōʻike i ka ili o Mars mea hiki oiʻawahia i ke ola ma mua o ko nā kānakaʻepekema mua manaʻo.

"Mākou nō e i ike nui e pili ana i ka make ana o ka Martian 'ia - Wadsworth olelo mai. - paha, i ka nui aa e ia no ke ola ana o ke koko kiʻekiʻe o ionizing pāhawewe, a komo iloko ma ka lahilahi lewa, a hiki i ka ili o ka Red Ka. Eia hou, nā haʻawina hōʻike i kekahi o na nā lātoma ma luna o kaʻili kai hiki e loaʻawahia. "

Sterilization o Spacecraft

Hoi mai a hiki i ka hoomaka ana o ko makou noho ana, 'aʻole i manaʻo' ia mākou e ole hopohopo e pili ana i ka sterilization o ka spacecraft mea i hoouna aku ai i Mars? Ano,ʻepekema mai i hiki i ka manawa, e makaikai i kekahi mau mea o ka Honua, ikeia me he kūikawā wahi, no ka mea, ka mea, i ole oaoieei-manawa kūpono e sterilize spacecraft i ke kiʻekiʻe lawa 'ilikai, e pale i ka pilikia o ka maʻiʻaʻai.

OʻAʻole pēlā poe noonoo ole. Nā kānakaʻepekema i hana i ke ao, kaulana ia kekahi ola ano, kapaʻia extremophiles ke ola mahope aku o ka loa ana. i nā koʻohune i i hoao i loko o ke ao, he extremophiles. Penei,ʻepekema nō mai i ike ina paha extremophiles ke ola ma luna o ka Martian ili honua.

"He nui ke hoʻomau i ka lawe i nā kaiapuni ole e contaminate Mars -ʻepekema olelo. - mākou i, e lawe i na mea he nui kaiapuni e disinfect a pau na mea paahana, a hiki i ke ao nei, e ho'āla ai i ka spacecraft ".

Where e nana no Martian ola

Like i ka Martian ola, e ole e pauaho. ʻOiai ka mea, ua olelo lealea i kekahi ola - microbial 'ole kekahi' ē aʻe - e e hiki ke ola ma ka Martian luna, lola honua ola nō mea e like manawa he maikai. Where ola meaola hiki ke hoomaluia ole wale ma ka pāhawewe akā, no hoi ma ka hana perchlorates.

ʻepekema mai i keia manawa ike i ka mamao ke komo iloko perchlorates. Akā, e hoʻoneʻe 'ia paha i kekahi mau mika ma lalo o ka ili o ke ola e nei. More 'ike nō e loaʻa i ka 2021, ka wā o kaʻeli nakekeʻEulopa ExoMars eia hoopa Mars. Nui iā sterilized, o ka papa.
