Heyadahan NASA oo kadhisan dalka Mareykanka ayaa sheegtay iney ku guuleysatay tijaabadii 1aad ee burburinta Dhagax Kusoo fuul lahaa dunida. Dhagaxan ( Asteroid )oo baryahanba warbaahintu hadal heysay ayaa looga cabsi qabay inuu ku soo dhaco dunida taasoo cabsi weyn ku heysa seynis yahana caalamka. Walow aan si rasmi ah loo baabi’in halista uu keeni dhagaxan ayaa hadan guushan yar ee tijaabada waxay u gogol xaareysaa sidii istaraatiijiyad wanaagsan oo lagu burburiyo loogu dajin lahaa.
Markii ugu horeysay taariikhda, dayax gacmeed ka yimid dhulka ayaa ku dhacay asteroid si uu u tijaabiyo habka aan uga badbaadin karno meereheena dabar goynta.
Dayax gacmeedkan oo lagu magacaabo NASA’s Double Asteroid Rendezvous Test (DART), ayaa ku dul dhacay hawada sare oo 7 milyan mayl (11 milyan oo kilomitir) u jirta dhulka caawa (Sept. 26) taas oo ay wakaaladda hawada sare ee Maraykanku ku dalacday in ay tahay tijaabadii ugu horaysay ee difaaca meeraha. Hadafka: in la beddelo wareegga dhagaxa hawada sare – loo yaqaan Dimorphos – agagaarka waalidkeeda asteroid-ka weyn ee Didymos oo ku filan si loo caddeeyo bini’aadamka ayaa ka leexin kara asteroid khatar ah haddii mid loo socdo Earth.
“Inta aan sheegi karno, tijaabadii ugu horreysay ee difaaca meeraha waxay ahayd guul,” ayay tiri Elena Adams, injineerada nidaamyada hawlgalka DART ee halkan jooga Jaamacadda Johns Hopkins ee Shaybaarka Fiisigiska (JHUAPL), ka dib shilka guusha. “Waxaan qabaa in dadyowga dunidu ay si fiican u seexdaan. Hubaal, waan yeeli doonaa.”
Taasi waa wax aysan dinosaurs-ku sameyn karin 65 milyan oo sano ka hor, markii Chicxulub asteroid-ka weyn uu ku dhuftay Jasiiradda Yucatan oo uu horseeday dabargooyo.
“Dinosaurs-yadu ma aysan haysan barnaamij hawada sare ah oo iyaga ku caawiya, laakiin anigu waan leenahay ayay tiri ,” Katherine Calvin, oo ah saynisyahanad sare oo katirsan NASA iyadoo isla markaana ah la taliyaha sare ee cimilada. ” Sidaas darteed DART waxay u taagan tahay horumarka muhiimka ah ee fahamka khataraha mustaqbalka iyo sida looga ilaaliyo meeraheena saameynta suurtagalka ah.” ayey sii raacisay.
