Lolu uhlelo okufanele lulandelwe olucaciswe yi-NASA uma kwenzeka i-asteroid ihlasela uMhlaba

Kuze kube namuhla iqiniso yilokho Umhlaba usongelwa kakhulu kunalokho ongakucabanga. Ukushiya eceleni umonakalo odalwa ngabantu kuleplanethi noma iqiniso lokuthi noma yiluphi uhlobo lwezimpi ezihlomile zomhlaba lungaqubuka nganoma yisiphi isikhathi, kunezinto zangaphandle okufanele sizicabangele nokuthi, uma singakulungele, zingaphela. ngokoqobo ngempilo eMhlabeni.

Lokhu yilokho iqembu lososayensi be-NASA ebelisebenza kulo, kuphrojekthi lapho kuyafundwa ngamathuba amakhulu okuthi iplanethi yethu inokuthi ishayiswe yi-asteroid. Lo mthelela, njengoba ungacabanga futhi inqobo nje uma i-asteroid inobukhulu nobukhulu obuthile, kungasho ukuthi ekugcineni yonke into ephilayo igcina ngokufa, yingakho i-NASA isithathe le phrojekthi ngokungathi sína kakhulu kunalokho ongakucabanga.

I-asteroid enkulu ingawisa impilo eMhlabeni

Ukukuqonda kangcono lokhu ngingathanda ukuthi sibeke umbono omncane ngale ndaba. Ngalesi sikhathi ngizobhekisa kokuthile okwenzekile ngempela, njenge umthelela ngo-2013 we-asteroid esifundeni saseChelyabinsk (eRussia). Ukuthola umbono, sikhuluma nge-asteroid engamamitha ayi-19 ububanzi. Ngaphandle kwalokhu, umthelela uthinte abantu abangaphezu kwe-1.200 150 futhi udale umonakalo ezakhiweni ebeziqhele ngamakhilomitha ayi-XNUMX ukusuka endaweni lapho i-asteroid igcine ishaye phansi.

Ngemuva kwalesi sibonelo, esinemibhalo eminingi ku-intanethi, ikutshele lokho kuze kube manje izinto ezingaphezu kwezingu-8.000 eziseduze kweplanethi yethu ezinamamitha angaphezu kwangu-140 ububanzi. Noma yimaphi ama-asteroid, uma kwenzeka ethinta uMhlaba, angaba namandla anele okusula izwe elilingana neSpain ebalazweni. Njengemininingwane yokugcina, akutshele ukuthi lezi zinto eziyi-8.000 kuphela, ngokwezibalo, zibanga ingxenye yesithathu yezinto ezihlupha uMhlaba.

I-NASA isilungiselele umbiko ochaza indlela eya phambili ukuze isinde kumthelela walolu hlobo

Ngenxa yalokhu, akumangazi ukuthi i-NASA, ngokubambisana ne-Federal Emergency Management Agency, zombili izinhlangano zase-United States, zilungiselele umbiko okhombisa izigaba ezinhlanu zezinyathelo ezizokwenziwa eminyakeni eyishumi ezayo.

Thuthukisa ikhono lokutholwa kwento eseduze ne-Earth

Inhloso yokuqala ebekwe yi-NASA ukusinda kumthelela we-asteroid enkulu ngokungenakuthinteka ibandakanya ukuthuthukisa ubuchwepheshe obusha obusinikeza indlela esheshayo nethembeke kakhulu yokuthola lesi sigaba sezinto. Namuhla izingqapheli ezifana neCatalina Sky Survey noma isibonakude iPan-STARRS1 ziphethe lo msebenzi.

Thuthukisa ukubikezela ukuthi enye yalezi zinto izofinyelela eMhlabeni

Iphuzu lesibili i-NASA egcizelela ukuthi lowo msebenzi kufanele uqale ukuthuthukisa zonke izibikezelo namathuba asebenza ngawo futhi lokho kusitshela ngesikhathi lapho enye yalezi zinto ingashaya khona uMhlaba. Ukuze kwenziwe lo msebenzi, inhloso ngqo ukukhulisa ukusebenzisana phakathi kwama-ejensi ahlukene kulokhu.

Thola izindlela zokuphambukisa ukuqondiswa kwe-asteroid

Njengephuzu lesithathu, uma usongo selutholakele, i-NASA ikhombisa ukuthi kufanele sicacise ukuthi singayiphambukisa kanjani i-asteroid. Ngalo mqondo, i-NASA sekunesikhathi eside isebenza kumaphrojekthi afana nalawo abizwa ngokuthi yi-Asteroid Redirection Mission, okusobala ukuthi yayingenye yalezo ezakhanselwa ngo-2017 ngabaphathi bakaTrump. Ukwenza umsebenzi wokuqagela njengale NASA ukubeke kwacaca ukuthi umkhumbi-mkhathi wamarobhothi kufanele usetshenziswe ngaphandle komkhathi osesikebheni.

Ukubambisana kwamazwe omhlaba kungaba yisisekelo

Ukubambisana kwamazwe amane kweNASA. Uma kulo mqondo sibhekisa emazwini ka-Aaron Miles, umeluleki weHhovisi LeSayensi Nenqubomgomo Yezobuchwepheshe e-White House: "kuyingozi yomhlaba wonke kubo bonke, futhi indlela engcono yokubhekana naleyo ngozi ukubambisana."

Kumele kwenziwe uhlelo oluphuthumayo

Njengephuzu lokugcina lesihlanu, i-NASA icele uhulumeni wase-United States ukuthi enze uhlelo oluphuthumayo okufanele lubekwe esimweni esingenakugwemeka sokuthi i-asteroid ekugcineni ishaye uMhlaba. Lolu hlelo luzofana nezici kulezo esezikhona nakwezinye izinhlekelele zemvelo, ngeshwa, kubonakala sengathi sesizijwayele kakhulu.
