Ngenxa yokuvuka ngokutsha komdla kwindalo iphela, kuyindalo kuthi Earthlings ukuba sikhathazeke ngokhuseleko lwamadoda nabasetyhini ngesibindi behlola umda wokugqibela. Kodwa ngaba sikhathazekile ngokwaneleyo malunga neendawo ezikude? Ubungozi obubangelwa kukuqengqeleka kwindawo evalekileyo bungaphezulu komoya nje oshushu.
Ukufumanisa Unqwenela ukuba uluntu lwazi malunga nengozi engabonakaliyo yokuhlaselwa kwegesi kwi-astronauts. Isifundo esivela kwi-1969 sinelungelo I-hydrogen yangaphakathi kunye ne-methane yamadoda ondle ukutya kwendawo (cimnqa ezo zixhobo, manenekazi!) Uvavanya ingozi yokuvumela umntu ukuba akrazule kwindawo evaliweyo kunye noxinzelelo:
Intsholongwane yamathumbu yenza iigesi ezimbini, i-hydrogen (H2) kunye ne-methane (CH4), enokubangela ingozi yomlilo kwigumbi elivaliweyo. Ke i-H2 kunye ne-CH4 ziyadlula kwi-anus kodwa ezi gesi nazo zihanjiswa ligazi lisiya emiphungeni lize lisuswe liye emoyeni.
Ukufumanisa indlela yokuthintela oosomajukujuku abangavelisiyo ekuveliseni isixa esikhulu segesi enokutsha, abaphandi bavavanye amaqela amabini olawulo lwamadoda angama-6 kangangeentsuku ezingama-42. Elinye iqela londliwa ukutya okungachazwanga kokutya kwendawo kwaye elinye lanikwa ukutya komhlaba oku-bland. Emva koko,
Ukuphefumla kunye neegesi zerektal zahlaziywa ngeeveki zokuqala nezokugqibela. Iigesi zeFlatus zahluka ngokubanzi kumaqela ezinto zokutya kodwa igesi eninzi yaveliswa ngokutya S kune-F.
Kwiiyure zokuqala ezili-12 zokurekhodwa kwedatha kuphela, izifundo ezondliweyo ngohlobo lwe-1960s lwendawo yokutya eveliswe ukuya kuthi ga kwi-209 ml ye-rectal H2, yona ijusi eninzi. Ngokulinganisa umyinge wokuphefumla kunye neegesi eziyimingxunya… lihlalutye iqela ligqibe kwelokuba elona xabiso liphezulu le-rectal H2 ekufuneka iqokelelwe ngexesha leeyure ezilishumi elinambini ngama-382 ml, kodwa loo miqulu iya kuba nkulu kunciphiso lwesiphekepheke kunye noxinzelelo lweemfuno.
Abaphandi bavumela iimeko zengqondo kunye ne-somatic ezichaphazela amathumbu, okt. Nangona isifundo singachazi ukuba amanqanaba oxinzelelo ayebaliwe kangakanani, yinto ekhuselekileyo yokuba ukwazi ukuba ukumbombozela kwabo bonke kuya kulinganiswa akwenziwanga nto ukuthomalalisa imithambo-luvo ye-gastronaut. Nokuba kwenzeka ntoni, mhlawumbi iimpembelelo zemood kwimveliso yerhasi evuthayo ecacisa umlilo Umxhuzulane ?
Ukuthetha ngemodeli yentsebenziswano yamazwe aphesheya eyi-ISS, umngcipheko ongachazwanga wokuqunjelwa kwindawo yengozi oyibangela kuxolo lwehlabathi. Ngobudlelwane baseRussia kunye ne-US eMhlabeni buxakeke, into yokugqibela amazwe ethu acaphukisayo ayayifuna kukuba abo bayinyibilikisayo bajongana nengxabano kwi-orbit.
Eyona nto iphambili kukuba nangona indawo igcwele iibhola ezinkulu ezidadayo zerhasi, ukuba ungusomajukujuku kungcono ushiye yonke loo methane kwizidalwa zasezulwini. Kungenxa yokuba esithubeni akukho mntu unokukuva kude, oko akuthethi ukuba kufanele - ICosmos Sele inengoma emnandi.
