Emasontweni ambalwa edlule besivele sinethuba lokukhuluma ngeqiniso lokuthi isiteshi sasemkhathini saseChina I-Tiangong-1 ukungalawuleki ngokoqobo, into engagcina ikwenze waphuthuma emhlabeni. Mhlawumbe ingxenye engasikhathaza kakhulu ngalo lonke lolu daba ukuthi, njengoba ingalawuleki, kuze kube nje ezinsukwini ezimbalwa ezedlule bekungaziwa ngokuqinisekile ukuthi izowela nini eMhlabeni futhi ikakhulukazi kuphi.
Ekugcineni kuye kwadingeka silinde kuze kube yilezi zinsuku ukuze sifunde imininingwane eminingi ngokuthi sonke isikhungo sesikhala siwa eMhlabeni. Ukwesaba, njengoba kwahlonzwa ngochwepheshe emasontweni edlule, ochwepheshe abahlale beqapha isimo seTiangong-1 ukuthi, ngenxa yobukhulu bayo, yayingeke ihlukane ngokuphelele lapho ingena eMhlabeni. impahla eyanele ibingawela olwandle, noma emhlabathini.
Umlando omncane ukuqonda ukuthi kungani iTiangong-1 ikhona
I-China ihlala igqama ukulandela uhlelo oluhluke kakhulu ngokobukhona bayo obukhethekile emjahweni wesikhala. Ngokwezwi nezwi nangalo mqondo singasho ukuthi iChina ihlale ilandela indlela yayo, yenza izimali ezidingekayo ngaphandle kwesidingo sokusebenzisana kwangaphandle. Unalokhu engqondweni, bekungekho kuze kube Septhemba 30, 2011 ngenkathi izwe likwazi ukufaka umzungezo walowo obhapathizwe njengoTiangong-1, okufana nokuthi ngo-2012 nango-2013 kwafika osomkhathi abangaba yisithupha ngaphakathi.
Ukuya ngemininingwane ethe xaxa, kufanele kuqashelwe ukuthi sikhuluma ngokuxakaniseka cishe amamitha ayi-10 ubude namamitha ayi-3 ububanzi. Yize yaba ilabhorethri encane kunazo zonke ephethwe ngumuntu emlandweni, yile ndlela eyabhabhathizwa ngayo umphakathi ngaleso sikhathi, iqiniso ukuthi sikhuluma nge Isakhiwo esingu-8.500 kg. Uma sibeka lesi sisindo ngendlela efanele, sikutshele ukuthi sicishe sifane naleso semikhumbi efana ne-SpaceX Dragon capsule engaba nayo, kude naleso esethulwe ezinye izakhiwo ezifana ne-Russian MIR enamakhilogremu ayi-120.000.
Lapho iTiangong-1 isifakiwe ku-orbit, ekuqaleni yaqala ukusebenza kumjikelezo wamakhilomitha angama-198 x 332 ukuphakama nama-degree angama-42 okuthambekela. Kamuva isiteshi sasemkhathini saba kukhuphuke kwafinyelela kumakhilomitha angama-336 x 353. Lapho lesi sikhundla sesifinyelelwe, isiteshi sasikhuliswa njalo kanye noma kabili ngonyaka, njengoba kudingeka, ukunxephezela ukungqubuzana. Ngalesi sikhathi nango-2016, uhulumeni wase-China wehluleka ukulawula isiteshi ngakho-ke abakwazanga ukuqhubeka nokwenza umsebenzi wokuphakamisa, osilethe lapho sikhona namhlanje.
ITiangong-1 ihamba ngamakhilomitha angama-27.000 / ngehora, into eyenza kungakwazi ukubikezela ukuthi izowela kuphi
Enye yezinkinga ezinkulu ososayensi ababhekana nazo lapho bebikezela ukuthi iTiangong-1 ingawela kuphi ukuthi, lapho ingena emkhathini, uhamba ngejubane eliseduze namakhilomitha angama-27.000 / ngehora. Lokhu kwenza indawo yayo yomthelela, njengoba ubona esithombeni ngenhla kwale migqa, ibanzi kakhulu. Noma kunjalo, kufanele kukhunjulwe ukuthi, ngokusho kwezitatimende ze-ESA ezisemthethweni, akufanele sibe nokwesaba ngoba, yize kunengozi yokuthi iTiangong-1 ifaka ukuwela ezwenikazi, iqiniso ukuthi amathuba okushaya umuntu noma isakhiwo angu-1 kwabayi-10.000 XNUMX.
Ngenxa yalokhu futhi, noma kunjalo isiteshi sasemkhathini kulindeleke ukuthi sigcine siwele eMhlabeni ngo-Ephreli 1, iqiniso ukuthi akufanele sibe noma sibheke lesi simo njengento eyingozi. Kuleli qophelo nokuqeda, ngithanda ukubhekisa kuNASA uqobo, okuyinhlangano phakathi kwezibalo ezishicilelwe, ememezele ukuthi amathuba okuthi into engaba ngamathani ayi-6 ingasishaya incane kakhulu kunaleyo ebikhonjiswe ngaphambilini. isigidigidi.
