Kwenzekile ukuthi noma yikuphi lapho kunomsebenzi wabantu, kudoti kufanele kuvele. Ngisho nesikhala bekungeyona into ehlukile. Lapho nje umuntu esethula izimoto zokuqala ezindizayo emzileni womhlaba, kwavela inkinga yemfucumfucu yasemkhathini, eba yimbi kakhulu minyaka yonke.
Yini imfucumfucu yesikhala?
Imfucumfucu yomkhathi ibhekisa kuzo zonke izinto ezenziwe ngumuntu futhi ezisendaweni eseduze nomhlaba, ngaphandle kokwenza noma yimiphi imisebenzi. Kukhulunywa nje, lezi yizindiza ezindize ezifeze umsebenzi wazo, noma zithole ukungasebenzi kahle okukhulu, okubavimba ukuthi baqhubeke nemisebenzi yabo ehleliwe.
Ngaphezu kwezakhiwo ezigcwele, ngokwesibonelo, iziphuphutheki, kukhona izingcezu zemikhumbi, izingxenye zezinjini, izinto ezihlukene ezihlakazekile. Ngokusho kwemithombo ehlukahlukene, ezindaweni eziphakeme ezihlukene zokujikeleza komhlaba, kunezinto ezingamakhulu amathathu kuya kwekhulu ezihlala zikhona, ezihlukaniswa njengemfucumfucu yasemkhathini.
Kungani imfucumfucu yasemkhathini iyingozi?
Ubukhona bezinto zokwenziwa ezingalawuleki esikhaleni esiseduze komhlaba kubeka ingozi ekusebenzeni kweziphuphutheki nemikhumbi-mkhathi. Ubungozi bukhulu kakhulu lapho abantu begibele. I-International Space Station iyisibonelo esihle sendiza ehlala abantu unomphela. Ukuhamba ngejubane elikhulu, noma izinhlayiya ezincane zemfucumfucu kungalimaza ukugudluza, ukulawula noma ukunikezwa kwamandla.
Inkinga yemfucumfucu yasemkhathini nayo icashile ngokuthi ukutholakala kwayo ezindleleni ezizungeze umhlaba kukhula njalo, futhi ngezinga eliphezulu. Esikhathini eside, lokhu kungaholela ekungenakwenzeka kwezindiza zesikhala nhlobo. Okusho ukuthi, ukuminyana kwe-orbit embozwe imfucumfucu engenamsebenzi kuzoba phezulu kakhulu kangangokuthi ngeke kudlule indiza ngale "veli".
Yini eyenziwayo ukuhlanza imfucumfucu yasemkhathini?
Ngaphandle kokuthi ukuhlolwa kwesikhala kwenziwe ngokwedlulele isikhathi esingaphezu kwengxenye yekhulu leminyaka, namuhla abukho ubuchwepheshe obulodwa obusebenzayo bokulawulwa kwemfucumfucu yomkhathi omkhulu futhi osebenzayo. Kukhulunywa nje, wonke umuntu uyabuqonda ubungozi bayo, kepha akekho owaziyo ukuthi angayiqeda kanjani. Ngezikhathi ezahlukahlukene, ochwepheshe abavela emazweni aholayo ahlola umkhathi ongaphandle baphakamise izindlela ezahlukahlukene zokucekela phansi udoti. Nazi ezithandwa kakhulu:
- Ukuthuthukiswa komkhumbi "wokuhlanza". Njengoba kuhlelwe, indiza ekhethekile izosondela entweni ehambayo, iyicoshe ebhodini bese iyithumela phansi. Le ndlela ayikho okwamanje.
- Isathelayithi ene-laser. Umqondo ukwethula isathelayithi ene-laser enamandla okufaka. Ngaphansi kwesenzo sogongolo lwe-laser, imfucumfucu kufanele ihwamuke noma okungenani yehle ngosayizi.
- Ukususa imfucumfucu ku-orbit. Ngosizo lwe-laser efanayo, imfucumfucu yayihlelelwe ukukhishwa emzileni wayo futhi ingeniswe ezingxenyeni eziminyene zomkhathi. Izingxenye ezincane kufanele zishe ngokuphelele ngaphambi kokufika ebusweni bomhlaba.
