Basa DART kuedza kwakaitwa neAmerican space agency (NASA) kuita bvunzo kutora matanho ese anodiwa kuitira kuti vanhu vagadzirire kutyisidzira kweasteroid. v192z
Mukuita, probe NASA ichadhumhana neasteroid 163 metres muhupamhi nechinangwa chekunonoka kutenderera kwayo. Nzwisisa kuti izvi zvichaitwa sei mukuita izvozvi.
Didymos uye Dimorphos asteroid data 2p4y3n
Yakawanikwa muna Kubvumbi 11, 1996 nemuongorori Spacewatch yaJoseph Montani kwete Kitt Peak National Observatory muTucson, Arizona, iyo asteroid Didymos inoyera 780 metres muhupamhi uye ine "munun'una": the Dimorphos, 163 mamita muhupamhi. Masayendisiti anoziva kuti Didymos iri makiromita mamiriyoni gumi nerimwe kubva paNyika.
Ose ari maviri hapana njodzi kuPasi panguva ino, asi iyo US space agency inoda kugadzirira kuitira kuti, kana zvichidikanwa, chirongwa chese chekuita chakagadzirira uye vanhu havatambure nekukanganisa kweasteroid yehukuru uhu. Didymos Zvinoreva "mapatya" muchiGiriki.
Inogona kutsanangurwa se "chinangwa chekupfura munzvimbo" chiitiko, mishoni DART Zviri nyore: NASA ichapisa iyo (isina kunyorwa) nzvimbo probe yakananga kune asteroid Dimorphos nechinangwa chekuderedza nguva yaanotora kufamba achitenderera Didymos. Mari yekuvaka yekuferefeta yaive US$250 miriyoni uye hongu, ichatumirwa zvakananga kuti iparadzwe uye ichinje mafambiro ekutenderera kwePasi. Dimorphos.
Haasi mazuva ese masayendisiti anokwanisa kuparadza chombo chemuchadenga chemadhora mamiriyoni mazana maviri nemakumi mashanu.
Elena Adams, DART mission systems engineer paJohn Hopkins Applied Physics Laboratory.
Masayendisiti anotarisira kuti chiitiko ichi chinonoke kupedzwa kwekutenderera nemaminetsi mashoma, imwe nguva inofanirwa kubatsira nekutarisa uye kuyerwa kweasteroid neEarth observatories. Maererano nehurumende data, the Dimorphos zvinotora maawa 11.9 kuti ipedze kutenderera kwayo.
Iyo DART space probe 1kr3i
Yakatangwa munaNovember 24, 2021, iyo NASA akashandisa roketi SpaceX Falcon 9 kubva kuVandenberg Air Force Base, California, sedanho rekutanga remishoni DART (acronym ye Kaviri Asteroid Redirection Bvunzo, iyo inogona kushandurwa seDouble Asteroid Redirection Test).
Chinhu chinodzorwa kure nePasi uye, pamwe chete, vanhu makumi mana nevana vanochitarisa kuti vaone kuti maitiro acho anofanira kuitika sei. Vesainzi vanozongokwanisa kuona mutumbi wedenga diki kana probe yemuchadenga yasara awa.
Ivo zvakare vanoziva kuti zvinogoneka chete kuona pixel imwe chete ye163-metres asteroid, asi izvi zvinofanirwa kuve zvakakosha kuti navigation system itarise. Dimorphos pane iyo asteroid yakakura. Maminitsi maviri nehafu kusati kwaitika, zvese zvichadzimwa uye nyanzvi dzichatora mafoto kuitira kuti zvidzidzo zviitwe gare gare.
Ngatingonongedza kamera uye titore mapikicha anoshamisa eiyi asteroid yatiri kuona kekutanga.
Elena Adams, DART mission systems engineer paJohn Hopkins Applied Physics Laboratory.
Pamusoro pekutepfenyura kwepamoyo, kamera yakaiswa pane probe yemumishini DART ichatumira mapikicha paminiti yekupedzisira kubonderana kusati kwaitika. The diki Italian spacecraft LICIACube (Chiedza cheItaly CubeSat yeKufungidzira Asteroids) yakatangwa neNASA probe uye yakaparadzaniswa munaGunyana 11, 2022.
Maererano neUS space agency, mota iyi ichabhururuka kwemaminetsi matatu ichitenderedza asteroid Dimorphos mushure mekuita uye zvichave zvichigoneka kuona rumwe rutivi rweasteroid diki, chimwe chinhu chaisazombogoneka nechitundumeme chakakura.
DART mishoni kugadzirira ramangwana 4m5c2f
Pfungwa yenyanzvi dzeNASA nderekuti hurongwa hwekuchengetedza Nyika kubva pakukonana kweasteroid inogadzirwa mukati memakore makumi matatu. Parizvino, hapana mutumbi wekudenga waonekwa uchienda kuNyika, asi neruzivo rwawanwa ikozvino, kuvandudzwa kwenzvimbo itsva yekuferefeta kunogona kupedzwa mukati memakore maviri. Ichi ndicho"inguva pfupi kwazvo yemitambo yeindasitiri yemuchadenga", inodaro Ian Carnelli, mukuru wechirongwa.
Mishoni ine zvikamu zviviri: mushure mekudhumhana, masayendisiti anozoona kuti asteroid ichaita sei kutenderera kwayo kutenderera. Didymos, ne "boost" yeNASA space probe. Izvi zvinofanirwa kubatsira kugadzira maitiro ekuchengetedza Pasi uye chii chinofanira kuitwa kana njodzi yechokwadi iripo.
Zvakafanana kana ukadonhedza wristwatch yako woikuvadza. Hazvina hazvo kuva nguva imwe chete. Iwe unogona kusazviona ipapo ipapo, asi mumavhiki nemazuva nemavhiki anotevera, iwe uchaona wachi yako ichimhanya nekukurumidza - uye isu tinoona iyo binary asteroid system inofamba nekukurumidza.
Tom Statler, musayendisiti wechirongwa cheDART.
Kudhumhana kweNASA kuchatepfenyurwa live 4w6a5b
Iyo US space agency ichatepfenyura live pachiteshi chayo pa YouTube saka vateveri vezvenyeredzi vanogona kutevedzera maitiro munguva chaiyo. Ingodzokera kune ino peji kubva 19pm Brasília nguva nhasi (26th) uye tevera maitiro ekurarama kuburikidza nerukova rwepamoyo pazasi. Kudhumhana kunotarisirwa na20:14 p.m.
Nhepfenyuro iripo NASA webhusaiti, peji pa Facebook e Twitter zvakare zvakarongwa kuti zviitike. Iva nechokwadi chekutevera zvese zvese!
