Icyogajuru cya DART cya NASA cyahinduye icyerekezo cya asteroide kizenguruka izuba

Guhindura Ibihe: Uburyo Misiyo ya DART ya NASA Yerekanye ko dushobora kurinda isi

Mu binyejana byinshi, abantu barebye mu kirere nijoro bavanze igitangaza nubwoba bubaho, bazi ko ikirere cyo kurasa mu kirere dutuyemo gifite iterabwoba. Ku ya 26 Nzeri 2022, ikiremwamuntu cyateye intambwe yacyo ya mbere iva ku ndorerezi itajenjetse ikagera ku izamu ry’imibumbe ikora. Icyogajuru cya NASA cyitwa Double Asteroid Redirection Test (DART) icyogajuru cyaguye nkana muri asteroide nto yitwa Dimorphos, gihindura iteka inzira yacyo mu kirere. Ntabwo byari bijyanye no kurimbura isi; byari hafi ya nudge isobanutse, ibarwa-gihamya-igitekerezo gishobora umunsi umwe gukiza isi yacu. Intsinzi ya DART irerekana gusimbuka cyane mubumenyi bwa siyansi, byerekana ko hamwe no kureba kure, ubufatanye, no gushyira mubikorwa neza, dushobora guhindura inzira yibintu byo mwijuru. Nukwibutsa gukomeye ko kubikorwa bigoye, bigoye-ubutumwa, haba gutandukanya asteroide cyangwa gukora ubucuruzi, kugira sisitemu yubatswe, modular ni urufunguzo rwo gukubita intego.

Inshingano: Kubara Isanzure Kubara

Intego ya DART yari yoroshye cyane mubitekerezo ariko bigoye cyane mubikorwa: kugirango bigaragare muburyo bugaragara umunyamuryango muto wa sisitemu ya binary asteroide, Didymos n'ukwezi kwayo Dimorphos. Izi couple zatoranijwe kuko ntakibazo kibangamiye isi, bituma iba laboratoire nziza. Icyogajuru, kingana na mashini yo kugurisha, cyagenze ibirometero birenga miliyoni 6.8 mu bwigenge, hifashishijwe uburyo buhanitse bwo kuyobora kugira ngo bugere kuri metero 170 z'ubugari bwa Dimorphos. Ingaruka zanyuma zigeze ku bilometero 14.000 mu isaha ni indorerezi zarebwaga na telesikopi ku isi yose hamwe na mugenzi wa DART, icyogajuru cya LICIACube. Ntabwo byari impanuka idasanzwe; byari imyigaragambyo yateguwe neza mugihe runaka kugirango hongerwe imbaraga zo kwimura imbaraga, gihamya imbaraga zo gutegura neza no guhindura igihe.

Igisubizo: Guhindura Amateka muri Orbit

Ikibazo kumitekerereze ya buri muhanga nyuma yingaruka ni: cyakoze? Ibyumweru byo kwitegereza no gusesengura amakuru bivuye kuri telesikopi ishingiye ku butaka byemeje yego. Mbere ya DART, Dimorphos yazengurutse umubyeyi munini wa asteroide, Didymos, buri masaha 11 niminota 55. Nyuma yingaruka, icyo gihe cya orbital cyagabanijwe niminota 32 itangaje - irenze kure igipimo ntarengwa cyamasegonda 73 kugirango utsinde. Ihinduka rikomeye ryerekanye tekinike ya kinetic tekinike ni nziza. Inshingano yahinduye neza inzira ya asteroide ntabwo ikikije Didymos gusa, ahubwo yahinduye neza izenguruka ryayo izenguruka izuba hamwe numubiri wababyeyi. Ibisubizo by'ingenzi byari:

• Guhindura ibihe bya Orbital: Yagabanijwe niminota 32, kuva 11h 55m kugeza 11h 23m.
• Kwemeza Tekinike: Yemeje ingaruka za kinetic nkuburyo bukomeye bwo kwirinda umubumbe.
• Umusanzu wa Ejecta: Yavumbuye ibisubizo bivuye mubintu byasohotse ("umurizo") byongereye imbaraga cyane gusunika, igisubizo gikomeye mubutumwa bw'ejo hazaza.
• Ubufatanye Mpuzamahanga: Amakuru yakusanyirijwe ku isi yose, kuva kuri telesikopi ya Hubble na Webb kugeza kuri obserwatori kuri buri mugabane.

Kuva muri Cosmic Defence to Business Precision

Kwambika asteroide bihuriye he no gukora umushinga? Byose. Inshingano ya DART yagenze neza kuko yubatswe kuri sisitemu ya modular - kugendana ubwigenge, kwitegereza kwigenga, gutanga amakuru ku gihe-byose bikorana hamwe bigamije intego imwe, ikomeye. Mubucuruzi bugezweho, ibigo bihura nibibazo byateganijwe bisaba ubwitonzi, amakuru yukuri, hamwe nubushobozi bwo guhindura inzira byihuse. Aha niho sisitemu yimikorere itunganijwe iba ingirakamaro.

"Intsinzi ya DART yasabye guhuza bidasubirwaho ikoranabuhanga rigezweho, isesengura ryamakuru nyaryo, hamwe nishyirwa mu bikorwa ryuzuye. Irerekana ko hamwe na sisitemu iboneye, dushobora guhangana n’ibibazo bitoroshye kandi twizeye."

Nkuko NASA yishingikirije kumasomo ahuriweho yo kugendagenda, kugenda, no gutumanaho, ubucuruzi bushobora kungukirwa na sisitemu ikora. Ihuriro nka Mewayz ryemerera amashyirahamwe guhuza ibikorwa byingenzi-CRM, imicungire yimishinga, imari, n’itumanaho - mu ihuriro rimwe, rihuza n'imiterere. Iyo buri gice cyibikorwa byawe gihujwe kandi amakuru akagenda yisanzuye, urashobora gufata ibyemezo byihuse, ugahindura ingamba zawe zishingiye kubitekerezo byukuri, kandi ukayobora ikizere ikigo cyawe kugana kuntego zacyo. Isomo riva muri DART rirasobanutse: waba uhindura inzira yumubiri wo mwijuru cyangwa ugashushanya inzira yumushinga wawe, intsinzi iterwa no kugira sisitemu ihuriweho, yitabira, hamwe na moderi yibanze.

Igihe gishya cyo kuba igisonga gikora

Inshingano ya DART yahinduye bidasubirwaho umubano wabantu nizuba. Ntabwo tukiri abagenzi gusa kuri Space Spacehip; twafashe uruziga, byerekana ko dufite ubushobozi bwo kurinda umubumbe wacu iterabwoba risanzwe. Ihagaze nkurugero rwiza rwibikorwa bya siyansi mpuzamahanga, bihindura siyanse mubumenyi bwa siyansi. Amakuru azamenyesha ingamba zo kurinda umubumbe uzaza mumyaka mirongo, harimo nubutumwa bwa ESA Hera buzaza gukora ubushakashatsi burambuye nyuma yingaruka. Kurangiza, DART ninkuru yubushobozi binyuze mubitegura n'ikoranabuhanga. Iratwigisha ko mukubaka sisitemu zubwenge, zishyizwe hamwe - zaba izirinda umubumbe cyangwa imbaraga zubucuruzi butera imbaraga - dushobora guhangana nigihe kizaza atari impungenge, ahubwo dufite ibyiringiro byateguwe.

Ibibazo bikunze kubazwa
