NASA's Double Asteroid Redirection Test (DART), oo ah hawshii ugu horeysay ee aduunka ee buuxda si ay u tijaabiso tignoolajiyada si ay uga difaacaan khataraha asteroid-ka ama kootada, ayaa bilaabay Arbacada 1:21 am EST SpaceX Gantaalka Falcon 9 oo ka yimid Space Launch Complex 4 East ee Vandenberg Space Force Base ee California.

Hal qayb oo kaliya NASAIstaraatiijiyada difaaca meeraha weyn, DART - waxaa dhisay oo maamula Johns Hopkins Shaybaadhka Fiisigiska la dabaqay (APL) ee Laurel, Maryland - waxay saameyn doontaa asteroid caan ah oo aan khatar ku ahayn Dhulka. Hadafka laga leeyahay waa in wax yar laga beddelo dhaqdhaqaaqa asteroid-ka hab si sax ah loo cabbiri karo iyadoo la isticmaalayo telescopes dhulka ku salaysan.

DART waxay tusi doontaa in dayaxgacmeedku uu si iskiis ah ugu socon karo asteroid-ka bartilmaameedka ah oo uu ula kac ugu dhici karo - habka leexinta ee loo yaqaan saamaynta kinetic. Tijaabadu waxay bixin doontaa xog muhiim ah si ay gacan uga geysato diyaarinta wanaagsan ee asteroid-ka taasoo keeni karta khatar saameyn ku yeelata Dhulka, waa haddii mid mar uun la ogaado. LICIACube, CubeSat oo wata DART oo ay bixiso Wakaaladda Hawada Talyaaniga (ASI), ayaa la sii dayn doonaa ka hor saamaynta DART si loo qabto sawirrada saamaynta iyo daruuraha ka dhashay walxaha la saaray. Ku dhawaad ​​afar sano ka dib saamaynta DART, ESA's (European Space Agency) mashruuca Hera ayaa samayn doona sahan tafatiran ee labada asteroids, iyadoo si gaar ah diiradda saaraya godka ay ka tageen isku dhaca DART iyo go'aaminta saxda ah ee baaxadda Dimorphos.

"DART waxa ay khiyaaliyada sayniska u beddeshaa xaqiiqo saynis waxayna markhaati u tahay firfircoonida NASA iyo hal-abuurnimada faa'iidada dadka oo dhan," ayuu yidhi. NASA Maamule Bill Nelson. "Marka laga soo tago dhammaan siyaabaha ay NASA u baarto koonkeena iyo meeraheena guriga, waxaan sidoo kale ka shaqeyneynaa sidii aan u ilaalin lahayn gurigaas, baaritaankani wuxuu gacan ka geysan doonaa in la caddeeyo hal dariiqo oo macquul ah oo meereheena looga ilaaliyo asteroid-ka khatarta ah waa in la ogaado waxa uu ku wajahanyahay dhulka.

Markay ahayd 2:17 subaxnimo, DART waxay ka soocday marxaladda labaad ee gantaalka. Daqiiqado ka dib, hawl-wadeenada hawl-wadeenada waxa ay heleen xogtii telemetry ee dayax-gacmeedka ugu horeysey waxayna bilaabeen hannaankii lagu hagi lahaa dayax gacmeedka meel nabdoon oo lagu geynayo aaladaha cadceedda. Qiyaastii laba saacadood ka dib, dayax-gacmeedku waxa uu dhammaystiray furfurista labadiisa, oo dhererkiisu yahay 28 cagood, oo fidsan qalabyada cadceedda. Waxay awood u siin doonaan hawada sare iyo NASA's Evolutionary Xenon Thruster - engine ion Commercial, mid ka mid ah dhowr tignoolajiyada lagu tijaabiyey DART si mustaqbalka loogu isticmaalo hawlgallada hawada.
