Mumwe haagone kutaura nezve asteroids pasina kutaura Bennu, hofori iyo, pasina kupokana, Iboka rekudenga rinokosha zvikuru nhasi. Iine dhayamita inodarika 500 metres nehuremu hukuru kupfuura hunotarisirwa. Nokudaro, ndiyo imwe yeasteroids ine simba zvikuru iyo inorara pedyo nePasi.
Kuwanikwa kwaro kunotanga muna 1999 muSocorro, United States, neboka rakazvipira kuferefeta zvisikwa izvi zvisinganzwisisike. Pakutanga, asteroid yakasarudzwa nerimwe zita, asi nekutenda kune anecdote inoda kuziva, akatumidzwa zita remadunhurirwa rokuti Bennu. Kubva ipapo, yanga iri nyaya yekuongororwa kwakawanda neNASA nezvimwe zvakadaro.
Zvichienderana nemhedzisiro yavo, zvakazarurwa zvikuru zvinogona kuuya kumberi maererano neasteroid uye zvimwe zvinhu zveSolar System. Nokudaro kukosha kwekudzidza kwayo nguva dzose.
Iwe unogona zvakare kufarira chinyorwa chedu: Chii chinonzi asteroid yakakura?
Iwe unoda kuziva zvakawanda nezve Bennu? Ziva zvese zvinozivikanwa kusvika zvino!

Yese asteroids inodzidzwa zvakanyanya neiyo NASA nokuda kwezvikonzero zvakasiyana-siyana, kuve njodzi inogona kuitika, imwe yacho. Asi kana iri Bennu, pane simba rinopfuura iro rakareruka chirevo.
Muna 2019, zvakaonekwa kuti hombe iyi asteroid ndeyekare pane yaimbofungwa. Kutenda kune iyi data nyowani, iyo yese ongororo yekuongorora yakasvika pamhedzisiro yekuti ndiyo inogona kutariswa inogona kupa ruzivo. nezvekwakabva hurongwa hunogara Nyika.
Sezvambotaurwa, Bennu inopfuura 500 metres mudhayamita. Pamusoro pezvo, inotenderera ichitenderedza axis yayo yega maawa mana ega ega. Nepo, zvishoma kudarika 4 gore zvinotora kutenderera Zuva.
Kune avo vanoda musoro wekuenzanisa, fungidzira Eiffel Tower kana Empire State Building. Zvivakwa zviviri izvi zvishoma kana zvichienzaniswa neasteroid. Wawana zano here?
Tichiongorora zvakawanda nezvazvo, dombo guru iri remuchadenga rinogara mubhandi reasteroid pakati peMars neJupiter. Inofungidzirwa kuti makore matanhatu ega ega, kusvika kwayo kwepedyo kutenderera kwePasi kunoitika, chiitiko chinoburitsa tarisiro huru. Kunyangwe pasina njodzi inooneka, inoramba ichimiririra kutyisidzira kunoonekwa uye kunogara kuchitariswa. Pamusoro pezvo, zvakakosha kuti uzive kuti mamwe maasteroids akadzidzwa, senge iyo inogona kukanganisa Nyika muna 2020.
Kubva pane izvi nezvimwe zvikonzero, muna 2016 iyo OSIRIS-REx space probe yakatangwa nechinangwa chekumhara pane asteroid. Magadzirirwo ayo achabvumira kuunganidzwa kwemasampuli kubva kumusoro mukuda kuburitsa pachena mifungo mitsva maererano neichi chisinganzwisisike, chakasviba, chiri kure uye chinoyemurika sidereal entity.
Asteroid Bennu Vs. OSIRIS-REx: Kusangana kwakamirirwa zvakanyanya
Iyo OSIRIS-REx spacecraft ine chinangwa chakakosha chinozoseta kosi yezviyedzo uye tsvagiridzo yeramangwana. Kubudirira kwaro kunofanirwa kunge kuchine simba kupa dzidziso itsva kana chokwadi chinoisa hwaro hwekwakabva Solar System.
Kubva payakatumirwa munaGunyana 2016, zvakatora makore anopfuura maviri kuti probe isvike kwayaienda. Zvakanga zvisiri kusvika Zvita 2018 paakatanga kuonana kwake kwekutanga kure, kuitira kutora mifananidzo yakarurama yeasteroid Bennu.
Chimwe chezvinhu zvinoshamisa zvakawanwa chaiva kuvapo kwemvura yakasanganiswa pamusoro peasteroid. Ruzhinji rwakanga rusina mukana uyu, saka fungidziro nepfungwa dzakarongwa maererano naBennu, dzakatora shanduko huru.
Kuongorora muchadenga kunofanira kutarisana negiravhiti yakaderera inotsanangurwa nechinhu ichi chemuchadenga, ichiva denho chaiyo. Zvisinei, zvinotarisirwa kuti nokukurumidza uye kurarama nemhoteredzo yebasa nenzira yakanakisisa, zvinangwa zvikuru zvitatu zvinofanira kuitwa panguva yacho zvichazadzikiswa zvizere.
Chekutanga cheizvi ndechekuchengetedza nguva dzose nezve nzira yayo uye mafambiro ayo maererano nePasi. Kutora nzvimbo mukati meboka reasteroids inogona kuva nengozi, nheyo dzakatanhamara dzinofanirwa kukweverwa dzinonyatso kujekesa maitiro uye kuumbwa kweasteroid Bennu.
Uyezve, OSIRIS-REx ichaunganidza pakati pe600 kusvika 2000 gramu yezvinhu, iyo ichashanda semureza wekuongorora kwezera re asteroid. Sezvo zvisingazivikanwe kuti inguva yakareba sei, aya masampula anozobatsira kuratidza nhamba inokodzera uye inoshanda segwara rekusimbisa nzira dzakasiyana dzekuzvarwa kweSolar System.
Chii chinonzi Bennu? Tora iwo azvino Bennu wongororo
Mufananidzo nerubatsiro: NASA
Sezvo kuvepo kweasteroid kwaizivikanwa, kune akawanda mazita emadunhurirwa akapihwa kwairi kusvika nhasi. Pakati pemafungiro akawanda pamusoro peBennu akasimbiswa nenharaunda, avo vasina mabhesi esainzi vanomira pachena. Muenzaniso weizvi ndiwo unoona asteroid se "dombo rerufu", nekuda kwehukuru hwayo uye njodzi inogona kuitika kupasi.
Nekudaro, zvinotarisirwa kuti NASA inokurumidza kuramba iyi mhando yekutaura. Zvinoratidzwa kuti Bennu, kunyangwe angave achityisidzira, hazvizokanganisa Nyika ikozvino kana munguva pfupi iri kutevera.
Kune chikamu chayo, iko zvino kudivi resainzi uye repamutemo, maonero ane chekuita nedombo regalaksi iyi akasiyana, asi ane hwaro hwakafanana. Nyanzvi dzeNASA neIAC dzakataura kuti kuumbwa uye chimiro cheBennu chiri dzakapfuma muzvinyorwa zvekare kuti vakanga vasingatarisiri kuwana pakutanga.
Regolith uye imwe kirasi yemakomponi nemvura uye kabhoni zvinongori zvimwe zvezvakawanikwa pane yakaongororwa pamusoro peiyo asteroid. Mamwe maonero pamusoro peBennu anovimbisa kuti imhando yeasteroid iyo, pakutanga, yakapa Nyika nemvura pavakairova mambakwedza eSolar System.
Saizvozvo, masayendisiti ane ruzivo mumunda akapokana kuti mambure emidziyo kubva kuBennu anogona kunge asingazivikanwe uye haambofa akagadziriswa. Saka, hukama hwavo nekutanga kweSolar System hunenge husina kunaka.
Iyo OSIRIS REx nzvimbo probe ichadzoka muna 2023 nevaunganidzwa. Kusavimbika kunogona kuve kwakakura pakuziva zvazvinounza. Uye iwe, iwe uchave wakatarisira ipapo?
