Kwiiveki nje ezimbalwa iTiangong-1 iya kuwela eMhlabeni kwaye akukho mntu waziyo kanye apho

Sele kuyiminyaka ngoku siyazi ngokusemthethweni loo nto iTshayina uphulukene nolawulo kwisitishi sakhe sendawo, i I-Tiangong-1. Njengesikhumbuzo, ndikuxelele ukuba kwakusekuqaleni kuka-2016 xa i-China Space Agency yaqinisekisa into eyayinamahemuhemu iinyanga kwaye yayingeyonto ilula nje yokuba, emva kwemizamo emininzi, babephulukene nolawulo lwakho lokuqala isikhululo sendawo.

Ngexesha lokuqinisekiswa okusemthethweni kuwo onke amajelo onomdla, yayiyiarhente ngokwayo ebeka etafileni uluhlu lweedatha ezinomdla, ngakumbi kwimeko apho kwakufuneka ilungiselele intlekele. Asithethi ngayo nayiphi na into ngaphandle komhla apho iingcali zawo zaxela kwangaphambili ukuba isikhululo sithuba ekugqibeleni siza kuwela eMhlabeni, sithetha phakathi kuka-Okthobha ka-2017 no-Epreli 2018, umzuzu osele ufikile kwaye malunga nedatha entsha.

Ngenxa yokuphakama apho nasiphi na isikhululo sendawo ejikelezayo, bathambekele ekuphulukaneni nokuphakama ngokuhamba kwexesha ngenxa yomxhuzulane

Ukuqonda okungcono kancinci ukuba kutheni iTiangong-1 iwela eMhlabeni kuyimfuneko ukuqonda ukuba namhlanje nayiphi na izikhululo ezahlukeneyo zesithuba ezijikeleza uMhlaba azihambi ngokungenammiselo kumjikelo wazo. Kuba zikummandla wobuchwephesha obuncinci, bawela kancinci kancinci emhlabeni ngenxa yamandla okutsala oku kusebenzayo. Isisombululo kukuba xa ukuphakama kwabo kwehla ukuya kwinqanaba elithile, oosomajukujuku basebenzise inkqubo yokuqhubela phambili ebuyisela isikhululo kwindawo yaso.

Yiyo kanye le ngxaki iChina yayifumana ngeTiangong-1. Njengoko yaba semthethweni kwiminyaka embalwa edlulileyo, ngokucacileyo kwaye ngaxa lithile ngo-Matshi 2016, i-China Space Agency yazama ukwenza izixhobo zeTiangong-1 ukuze kwenziwe inkqubo eyimfuneko yokufumana abaqhubi benqanawa kwaye bayibuyisele orbit, ngelishwa unxibelelwano aluphumelelanga nto leyo ethetha ukuba phulukana nolawulo ngenqanawa isikhokelele kwimeko esizifumana sikuyo namhlanje.

Emva kwexesha elide lokulinda, kwiiveki ezimbalwa ezizayo iTiangong-1 iyokuwa eMhlabeni

Njengoko ubona kwimigca yangaphambili, okwangoku sele sikwixesha apho iingcali zaseTshayina zibalwe ukuba iintsalela zeTiangong-1 ziwele eMhlabeni. Okwangoku, kufanele ukuba kuqatshelwe ukuba ekugqibeleni ibe ziingcali ezivela kwi-European Space Agency (i-ESA) abathe bazama ukuphinda baqikelele lo mhla ngokuwunciphisa ukuya kwinqanaba elithile phakathi kuka-Matshi 24 no-Epreli 9Oko kukuthi, intsalela yeTiangong-1 engatshabalaliyo ekungeneni.

Zingaphi inkunkuma ezinokuthi ziwele eMhlabeni? Oku kuyinyani yokuba zonke iingcali zithi azazi, kufuneka kuthathelwe ingqalelo kweli nqanaba lokuba sithetha ngento I-8,5 itoni kwaye malunga ne-10 yeemitha ubude nge-4 yeemitha ububanzi. Okwangoku, kufanele ukuba kuqatshelwe ukuba uninzi lwesikhululo siya kuchithakala kwimpembelelo yaso ngokuchasene nomoya ojikeleze umhlaba, nangona kunjalo, kuyalumkiswa ukuba ezinye iziqwenga ezimalunga ne-3 kilograms zingawela phezu komhlaba, ngokwezibalo, kungenzeka ukuba lulwandle. Kude kube lusuku oluphambi kokuba ingaziwa indawo apho iintsalela zinokuwa khona.

Ngenxa yokuthambeka komgangatho we-42 ye-orbit, iingcali ziqikelela ukuba inkunkuma inokuwela kwindawo apho amazwe anje ngeArgentina, iUnited States, iJapan, iNew Zealand okanye España phakathi kwabanye. Ngaphandle kwezi ndaba, iingcali zifuna ukuzola kuba, ngokwezibalo zabo, Ithuba lokuba esinye sezi ziqwenga singakubetha simalunga nezigidi ezili-10 eziphindwe ngaphantsi kwelo lokubethwa ngumbane.
