Abaphandi izama ukufumana isizathu sokuba oosomajukujuku babuyela Earth nge ukungaboni

Cosmonauts kunye oosomajukujuku ndiqhuba ixesha elide kwizikhululo Orbital, kwiimeko ezininzi wabuyela Earth ngumbono bawa. De kube ngoku, oosonzululwazi angamisela unobangela wale meko, nto leyo ithetha ukuba sisongelwa - impilo yabantu abazilungiselela kokoyiswa indawo engaphandle kwixesha elizayo. Mhlawumbi, ngoku kuluntu lwezenzululwazi kwakukho isisiza ukuba isenzeko.

Malunga nama-80 ekhulwini ngokonakala oosomajukujuku

Abaphandi beYunivesithi Miami baye bafumanisa isizathu ekhokelela ukuba ukulahleka kwenxalenye umbono. Ngokutsho koqikelelo lwabemi ezahlukeneyo, impilo emandundu iliso emva Earth malunga nama-80 ekhulwini bamazwe isithuba. Abaninzi kubo bawe umbono kunye lwegazi intracranial. Noko ke, izazinzulu ukusuka Miami baba abakakulungeli ukunxulumanisa ngqo nesenzeko ezimbini logama nje awunalo nofifi apho. Eku sunguleni, intelekelelo sele yenziwe kuluntu lwezenzululwazi ukuba ulwelo weightlessness awukwazi lisasazwe yi umzimba njengoko wenza Earth. Kubonakala ukuba le kokucingelwayo lisivezela ngokwenene.

Yintoni ebangela xi iliso?

Umbhali Lead Noam Alperin uthi iimeko womxhuzulane on Earth umxhuzulane siyakrazula phantsi emzimbeni izinto ulwelo. Nangona kunjalo, izimo weightlessness waphawula ulwelo yokufudukela kwelinye icala (ukuba intloko). flow fluid ingqondo ibangela uxinzelelo intracranial okwandileyo kwaye ngokutsha yayo zone iziseko evusa ukwanda koxinzelelo intraocular. oosomajukujuku abaninzi eqhuba weightlessness iinyanga, wabuyela uMhlaba kunye astigmatism. Ngelishwa, kwiimeko ezininzi, esi sifo nemiphumo vuhlayiseki. Ngamanye amazwi, umbono oosomajukujuku mandundu kakhulu ubomi.

Izazinzulu Sigxininisa ukuba lo mba sizalwa kuphela kwabo kunyanzeleka ukuba ahlale phezu kwisikhululo isithuba ixesha elide. UGqirha Alperin wathi kukwehla oosomajukujuku abandakanya moya elifutshane, kwabhalwa.

ukuhlolwa okuphelele

Ngenxa iqela lophando aba bonke neencindi zomzimba. Izazinzulu ezivela Miami banomdla ulwelo lwe-cerebrospinal. Le into yenzelwe ukukhusela ingqondo umnqonqo ukusuka lokungcangcazela kunye nokothuka. Nokunikezelwa nomthamo ulwelo ukuya neziseko iliso kudale ukonakala umbono (isithunzela yezinto baba akuboni kunye fifi). Ekungeneni le ventricle cerebrospinal fluid kubangela uxinzelelo intracranial. Kubalulekile ukukhumbula ukuba kanye nezihlunu izibilini kwezi nguqu aye aqatshelwa.

iindlela Ukufuna ukuziphendulela

Iziphumo zophononongo ziye zanikezelwa kwintlanganiso yonyaka ye-radiology Society of North America e Chicago. Ngokutsho izazinzulu, ngoku yatyhilwa unobangela kukwehla oosomajukujuku, kuyanceda ukujonga iindlela zokuphuma meko. Iingcali NASA banomdla ekufumaneni isisombululo ngokukhawuleza kangangoko kunokwenzeka. Ukuza kuthi ga ngoku, i-arhente isithuba abasebenzi nezicwangciso lokuphinda imiqathango weightlessness on Earth, kunye nophando ngakumbi.
