Koj puas tseem xav dhau los ua tus kws tshawb fawb?

Qhov chaw mus ncig yog txuam nrog kev sib hlub, kev ua yeeb yam thiab kev lom zem tiag tiag. Tab sis qhov tseeb, qhov no yog kev ua haujlwm nyuaj uas cuam tshuam nrog kev pheej hmoo rau lub neej, teeb meem kev noj qab haus huv thiab ib pawg ntawm cov teeb meem niaj hnub.

1. Qhov chaw tsw tsw phem

Cov neeg uas tau nyob hauv qhov chaw piav qhia nws cov ntxhiab tsw ntawm ntau txoj kev, tab sis tsis muaj leej twg hu nws qab ntxiag. ISS tau hais tias tsw tsw zoo li "kib steak" thiab "kub hlau". Astronaut Thomas Jones hais tias qhov chaw muaj "qhov txawv ntawm qhov tsis hnov tsw ntawm ozone, faint thiab pungent," nrog cov hmoov phom thiab leej faj.

Chemist Steve Pearce rov tsim cov ntxhiab tsw ntawm Mir chaw chaw nres tsheb rau kev kos duab teeb tsa Impossible Smells hauv xyoo 2008, thiab NASA pom qhov tshwm sim ze rau qhov tseeb - nws yog qhov sib xyaw ntawm hws taw thiab lub cev tsis zoo, ntsia thawv polish tshem tawm thiab roj av.

Astronaut Scott Kelly hais tias ISS tsw zoo li cov thoob khib nyiab, tshuaj tua kab mob thiab lub cev tsis huv, zoo li Harris County Jail nws ib zaug mus xyuas (tsis yog neeg raug kaw).

Thiab lwm tus kws tshawb fawb, Don Pettit, tau hais tias nws hnov cov ntawv sau ntawm cov pa taws.

Lwm qhov chaw ntawm qhov chaw yuav hnov tsw zoo dua. Muaj qhov ua tau tias cov pa roj thiab hmoov av nyob ib puag ncig cov hnub qub yug tshiab, piv txwv li Sagittarius B2, muaj ntxhiab tsw nrog raspberries thiab rum vim ethyl formate hauv lawv cov muaj pes tsawg leeg. Tab sis peb tsis zoo li yuav hnov lawv: lawv nyob deb tsis xav txog, txav mus rau hauv lub tshuab nqus tsev thiab, ntxiv rau, muaj tshuaj lom.

2. Cov dej haus tau los ntawm cov zis thiab tawm hws

Txij li thaum nws kim dhau mus tas li tso cov nkoj thauj khoom nrog cov dej haus mus rau ISS thiab tsis muaj qhov twg tau txais cov kua hauv qhov chaw, cov neeg caij nkoj yuav tsum haus cov dej rov ua dua. Nws yog tsim los ntawm cov zis thiab hws ntawm lub chaw nres tsheb cov neeg coob thiab saj ib yam li cov dej zoo tib yam, yog li koj tsuas yog yuav tsum tsis txhob xav txog qhov twg nws tuaj.

Nyob rau hauv ib xyoos, ib tug neeg haus 730 litres ntawm recycled hws thiab tso zis.

ISS dej recirculation system raug nqi txog $ 250 lab thiab ua haujlwm ntawm lub hauv paus ntsiab lus ntawm electrolysis. Nws yog qhov nthuav tias Lavxias teb sab cosmonaus tsis nyiam haus cov kua li no thiab nyiam qhov ua los ntawm condensate ntawm exhaled cua.

Lawv tsuas yog ntxuav nrog dej los ntawm cov zis. Tab sis lawv ua siab zoo muab lawv cov zis rau kev ua haujlwm rau Asmeskas ntu, thaum cov neeg nyob sib ze tsis muaj txaus rau lawv.

Rau cov poj niam ntawm ISS, nws yog qhov nyuaj tshwj xeeb vim tias cov txheej txheem rov ua haujlwm tsis tuaj yeem ua cov ntshav coj khaub ncaws. Astronauts yuav tsum siv tshuaj los txwv lawv lub sijhawm, uas tej zaum yuav tsis zoo rau lawv txoj kev noj qab haus huv.

3. Cov khoom ntawm tib neeg daim tawv nqaij ntab hauv huab cua ntawm ISS

Thaum cov keratinized flakes ntawm koj cov tawv nqaij flakes, lawv tsuas yog poob rau hauv av nyob rau hauv lub zog ntawm lub ntiajteb txawj nqus thiab sib tov nrog hmoov av. Tab sis nyob rau hauv qhov chaw, nyob rau hauv tej yam kev mob ntawm microgravity, hais txog ib tug neeg tuag epidermis yog tas li plying nyob ib ncig ntawm lub chaw nres tsheb.

Raws li cov kws sau hnub qub Mike Massimino thiab Don Pettit, tshwj xeeb tshaj yog tej yam tsis kaj siab tshwm sim thaum ib tug neeg hloov khaub ncaws. Koj tshem koj cov thom khwm, thiab cov huab ntawm daim tawv nqaij tuag, lub npe hu ua detritus, kis rau saum huab cua. ISS yeej tsis yog qhov chaw rau cov neeg squeamish.

Scott Kelly, thaum lub sijhawm Q&A kev sib tham ntawm Reddit, tau lees paub tias thaum thawj lub hlis ntawm ISS, txhua tus calluses tev tawm ntawm ko taw thiab ob txhais ceg ua du thiab liab, zoo li tus menyuam mos.

Tom qab nyob hauv qhov chaw tau ob peb lub hlis, tshem koj cov thom khwm kom zoo, txwv tsis pub cov kwj deg ntawm cov tawv nqaij tuag yuav nkag mus rau hauv tsev. Thiab koj yuav sai sai dhau los ua tus neeg nyiam tshaj plaws ntawm cov neeg coob.

4. Koj tuaj yeem hloov khaub ncaws ntawm ISS txhua 4 hnub

Raws li Don Pettit qhov kev nco qab, cov khoom lag luam ntawm linen ntawm ISS tsis yog tsim los hloov ntau zaus, yog li qhov no yuav tsum tau ua ib zaug txhua 3-4 hnub.

Cov neeg coob ntawm rau qhov tsim tawm kwv yees li 900 phaus (lossis 400 kilograms) ntawm cov khaub ncaws siv hauv ib xyoos.

Thiab txij li dej tsis txaus ntawm ISS, cov neeg caij nkoj tsis ntxuav lawv cov khaub ncaws. Feem ntau. Cov khaub ncaws hnav ntev npaum li lawv tuaj yeem ua tau, thiab thaum lawv tsis xis nyob hauv lawv, lawv tau thauj mus rau hauv cov tshuaj tsis tuaj yeem rov qab los ntawm Progress spacecraft, undocked los ntawm ISS thiab de-orbited. Yog li ntawd, tej yam no kub hnyiab tau hauv qhov chaw.

5. Kev ntxuav ntawm lub nkoj tsis muaj

Ntawm Mir thiab Skylab chaw nres tsheb, cov cosmonauts tau da dej. Thiab txawm hais tias nws tsis tuaj yeem siv nws ntau zaus, nws ua rau lub neej nyuaj hauv orbit yooj yim dua. Ntawm ISS, txawm li cas los xij, lawv txiav txim siab tsis npaj da dej.

Yog li ntawd, cov neeg coob tsis da dej nyob rau ntawd, tab sis tsuas yog so nrog cov ntaub so ntub thiab kua xab npum. Cov seem ntawm cov xab npum yog ntxuav tawm nrog dej me me, uas tsim nyog nws qhov hnyav hauv kub ntawm no. Rau cov plaub hau, siv tshuaj zawv plaub hau tshwj xeeb, uas tsis tas yuav yaug.

Muab hais tias cov astronauts nquag ua haujlwm ob peb teev hauv ib hnub los tiv thaiv cov leeg nqaij thiab tawm hws ntau, tsis tuaj yeem ntxuav tau zoo yog qhov teeb meem loj. Txawm li cas los xij, tib neeg tau siv rau qhov no thiab.

6. Cov kws tshawb fawb muaj qhov ntswg qhov ntswg txhua lub sijhawm

Yuav ua li cas astronauts zam tag nrho cov saum toj no rau ntau lub hlis, thaum lawv saib kav ntev? Tej zaum nws yuav yooj yim dua rau lawv vim tias lawv yuav luag ib txwm muaj qhov ntswg. Qhov tseeb yog hais tias nyob rau hauv lub ntiaj teb, cov kua los ntawm cov mucous membrane ntws los ntawm lub qhov ntswg kab noj hniav mus rau hauv lub pharynx thiab nqos imperceptibly. Tab sis nyob rau hauv microgravity, nws nyob twj ywm hauv lub qhov ntswg.

Gene Hunter thiab Michelle Perchonok, uas yog tus saib xyuas NASA txoj haujlwm tshawb fawb txog zaub mov, tau pom tias cov neeg caij nkoj tshwj xeeb nyiam cov khoom noj ntsim, qaub, lossis qab zib, xws li Tabasco ntses. Qhov no yog vim qhov saj ntawm cov zaub mov zoo tib yam nrog lub qhov ntswg qhov ntswg tsis txawv heev.

7. Kev quaj hauv qhov chaw mob

Tej zaum qhov tseeb saum toj no rhuav tshem koj txoj kev npau suav thaum yau ntawm qhov chaw thiab koj npaj txhij los ua kua muag. Tab sis astronauts yog deprived ntawm xws khoom kim heev: nws tsis yog li ntawd tsis yooj yim sua kom lawv quaj, tab sis nws yog undesirable. Hauv cov xwm txheej microgravity, kua muag tsis ntws tawm ntawm lub qhov muag, tab sis nyob twj ywm, ua rau mob hnyav thiab cuam tshuam rau kev pom.

Raws li shuttle pilot Ron Paris tau hais tias, thaum lub kua muag hauv qhov chaw loj txaus, lawv tseem tuaj yeem ya tawm ntawm qhov muag. Ces lawv cia li ntab ncig koj. Yog li, yog tias koj tsis tuaj yeem pab quaj txhua, sim, ntawm qhov tsis sib xws, quaj ntau dua.

8. ISS muaj cov kab mob sib txawv

Nws ntseeg tau tias qhov chaw kuaj mob yuav tsum huv heev. Tom qab tag nrho, astronauts mus dhau kev cais tawm ua ntej mus rau lub davhlau. Tab sis qhov tseeb, qhov chaw nres tsheb thoob ntiaj teb muaj cov kab mob. Cov kev tshawb fawb tau pom tias muaj ntau dua 4,200 hom. Qhov no tshaj qhov concentration ntawm cov dav hlau uas koj feem ntau ya mus so. Thiab sterility ntawm ISS tsuas yog tsis yooj yim sua kom tswj tau.
