Esi sisicwangciso ekufuneka sisilandele sicacisiwe yi-NASA kwimeko ye-asteroid ehlasela uMhlaba

Kude kube namhlanje inyani yile Umhlaba usesichengeni ngakumbi kunokuba unokucinga. Ukushiya ecaleni umonakalo owenziwa ngabantu kwiplanethi okanye inyani yokuba naluphi na uhlobo lomlo oxhobileyo unokuqhuma nangaliphi na ixesha, kukho izinto zangaphandle ekufuneka sizithathele ingqalelo kwaye ukuba, ukuba asilungelanga, zinokuphela. ngokoqobo ngobomi eMhlabeni.

Yiyo kanye le nto iqela lezazinzulu le-NASA belisebenza kuyo, kwiprojekthi apho Amathuba amakhulu okuba iplanethi yethu inokubethelwa yi-asteroid iyafundwa. Le mpembelelo, njengoko unokucinga kwaye nje ukuba i-asteroid inobukhulu kunye nobunzima, kunokuthetha ukuba ekugqibeleni yonke into ephilayo iphela isifa, kungoko iNASA iyithathile le projekthi ngokungathí sina kunokuba unokucinga.

I-asteroid enkulu inokuwisa ubomi eMhlabeni

Ukukuqonda ngcono oku ndingathanda ukuba sibeke umbono omncinci ngalo mbandela. Ngeli xesha ndiza kubhekisa kwinto eyenzekileyo ngokwenene, njenge ifuthe kwi-2013 ye-asteroid kwingingqi yaseChelyabinsk (iRussia). Ukufumana umbono, sithetha nge-asteroid malunga ne-19 yeemitha ububanzi. Ngaphandle koku, ifuthe lichaphazele abantu abangaphezulu kwe-1.200 kwaye lenze umonakalo kwizakhiwo ezazikumgama ongama-150 eekhilomitha ukusuka kwindawo apho i-asteroid yagqithela khona emhlabeni.

Emva kwalo mzekelo, apho kukho amaxwebhu amaninzi kwi-intanethi, xelela ukuba namhlanje bafumanekile ngaphezulu kwezinto ezingama-8.000 ezikufutshane nomhlaba wethu ongaphezulu kweemitha ezili-140 ububanzi. Nayiphi na kwezi asteroids, kwimeko yokuchaphazela uMhlaba, iya kuba namandla aneleyo okususa ilizwe elilingana neSpain kwimephu. Njengeenkcukacha zokugqibela, xelela ukuba ezi zinto zingama-8.000 XNUMX kuphela, ngokwezibalo, zenza isinye sezinto ezintathu ezikhathaza uMhlaba.

I-NASA ilungiselele ingxelo echaza indlela eya phambili ukuze iphile kwifuthe lolu hlobo

Ngenxa yoku, ayothusi into yokuba i-NASA, ibambisene ne-Arhente yoLawulo oluNgxamisekileyo ye-Federal, zombini iiarhente ezimbini zase-United States, zilungiselele ingxelo ebonisa ukuya kuthi ga kwizigaba ezintlanu zenyathelo ekufuneka zenziwe kule minyaka ilishumi izayo.

Ukuphucula ukubonwa kwento ekufuphi noMhlaba

Injongo yokuqala ebekwe yi-NASA ukusinda kwimpembelelo ye-asteroid enkulu kubandakanya ukuphuhlisa itekhnoloji entsha esinika indlela ekhawulezayo nethembeke ngakumbi yokufumanisa olu didi lwezinto. Namhlanje izinto zokujonga ezifana neCatalina Sky Survey okanye iPan-STARRS1 telescope ziphethe lo msebenzi.

Phucula uqikelelo lokuba enye yezi zinto iya kufikelela eMhlabeni

Inqaku lesibini lokuba i-NASA inyanzelise ukuba umsebenzi kufuneka uqale kukuphucula zonke iingqikelelo kunye namathuba asebenza ngawo kwaye esixelela malunga nomzuzu apho enye yezi zinto inokuthi ifike eMhlabeni. Ukwenza lo msebenzi, ujolise ngqo ekwandiseni intsebenziswano phakathi kweearhente ezahlukeneyo malunga noku.

Fumana iindlela zokuphambuka kwicala le-asteroid

Njengengongoma yesithathu, sakuba nje sifunyenwe isoyikiso, i-NASA ibonisa ukuba kufuneka sicace gca malunga nendlela esinokuphambuka ngayo kwi-asteroid. Ngale ndlela, i-NASA kudala isebenza kwiiprojekthi ezinje ngokuba zibizwa ngokuba yi-Asteroid Redirection Mission, ekubonakala ukuba yenye yezo zarhoxiswa ngo-2017 ngolawulo lukaTrump. Ukwenza i-hypothetical mission efana nale NASA ikubeke kwacaca ukuba i-robotic spacecraft kufuneka isetyenziswe ngaphandle koosomajukujuku ebhodini.

Intsebenziswano yamanye amazwe isisiseko

Intsebenziswano yesine ye-NASA. Ukuba kule ngqondo sibhekisa kumazwi ka-Aaron Miles, umcebisi kwi-Ofisi yezeNzululwazi kunye noMgaqo-nkqubo weTekhnoloji yeNdlu eNtshonalanga: "yingozi emhlabeni wonke kubo bonke, kwaye eyona ndlela yokujongana nale ngozi kukusebenzisana."

Kufuneka kwenziwe isicwangciso esingxamisekileyo

Njengengongoma yesihlanu yokugqibela, i-NASA icele urhulumente wase-United States ukuba enze isicwangciso esingxamisekileyo ekufuneka sibekwe kwimeko engenakuphepheka yokuba i-asteroid igqibe umhlaba. Esi sicwangciso siya kufana neempawu kwezo sele zikho kwezinye iintlekele zendalo, ngelishwa, kubonakala ngathi sisetyenziswa ngakumbi.
