Ikozvino hazvisi mumafirimu eHollywood chete kuti varume vanokwanisa kutsausa asteroid uye kuchengetedza vanhu vese. A National Aeronautics uye Space istration (NASA)) akasimbisa, mumusangano wehurukuro wakaitwa musi weChipiri (11), kuti akabudirira kutsausa nzira yeasteroid, panguva yekuedzwa kwekukwanisa kwevanhu kuzvidzivirira kubva pane zvinogona kuitika. 4x5a3m
Kuita izvi, chikepe DART basa nekuzvidira yakabonderana, musi wa26 Gunyana, neasteroid Dimorphos, iri satellite yeasteroid hombe, inonzi Didymos, uye iri pedyo. 11 mamiriyoni emakiromita kubva paNyika. Nenzira iyi, akakwanisa kuifambisa, akadaro mukuru wesangano remuchadenga, Bill Nelson, uyo akatiwo izvi ndizvo. "Nguva yakasimba yekudzivirira kwepuraneti uye nguva yakakosha yemunhu".
Nelson akataurawo kuti, kusati kwaitika, Dimorfo akatora maawa gumi nerimwe nemaminetsi makumi mashanu kutenderera asteroid yayo yakakura, iyo inoumba iyo mbiri asteroid system. Sekureva kwake, chitundumeme chakakwanisa kudzikisa kutenderera uku mumaminitsi makumi matatu nemaviri, achimiririra a 4% shanduko munzira. Nekuda kweizvozvo, kutenderera kweDimorph zvino kwafamba anenge mamita gumi kuswedera kune imwe asteroid, uye chinjo inoguma mukufamba kwayo ndeyechigarire. (https://blogs.20minutos.es/) “Zvingadai zvakabudirira kudai yakadzoreredza [kutenderera] pasi nemaminetsi angangoita gumi, asi yakatoita zvishoma nezvishoma nemaminetsi makumi matatu nemaviri.", akapemberera mukuru wesangano remuchadenga.
Kuchinja kwakarangarirwa “zvinoshamisa uye zvinokurudzira” naNancy Chabot, sainzi wemapuraneti kuJohns Hopkins Applied Physics Laboratory (APL) uye mutevedzeri wemutungamiri weMeteoritical Society:
Iyo DART mishoni yakaratidza kuti isu tinokwanisa kushandura matrajectories tichishandisa maitiro ekukanganisa. Kiyi yeiyi kukurumidza kuonekwa [kweasteroids inogona kunge iri kunanga kuNyika.

Saka zvakajairika mukugadzirwa kwemafirimu, kupindira kwevanhu mumigwagwa yeasteroid hakuna kumbobvira kwaitwa munhoroondo yevanhu. Muedzo wakanangana nekuona kuti woita sei mune imwe nguva yeramangwana iyo Nyika inoda kuchengetedzwa kubva kune asteroids yakafanana neiyo yakakonzera kutsakatika kwemadinosaur makore 66 miriyoni apfuura.
Zvinofungidzirwa kuti kune akakomberedza 10 pedyo-Earth asteroids ayo anosvika 140 metres muhukuru. Masayendisiti achiri kufunga kuti kune zvinopfuura zviuru gumi nezvishanu zvezvinhu izvi zvichawanikwa mumakumi emakore ari kuuya. Nekudaro, hapana kana mumwe wavo ane mukana wakakosha wekusvika pasirese mumakore zana anotevera, sekureva NASA.
Tsvakiridzo yakashandiswa mumishini iyi yakatangwa munaNovember 24, 2021 kubva kuVandenberg Air Force Base, California. Kushandisa roketi SpaceX Falcon 9, chinhu ichi chaidzorwa kure nePasi uye, pamwe chete, vanhu makumi mana nevana vakachitarisa panguva yekukanganisa.
Panguva yemusangano wevatori venhau, North America space agency yakaratidza kuti iyi data ingori mavambo eruzivo rwese rwainotarisira kupihwa nebasa iri rose. 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 iko zvino, 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.
Pamusoro peNASA, iyo European Space Agency (ESA) ari kugadzirirawo basa rake rokuswedera pedyo nedombo. Kuti iite izvi, ichashandisa HERA spacecraft, yakarongerwa kutanga muna 2024. Panguva imwecheteyo, China iri kurongawo basa rekudzivirira kwepasi makore mana kubva ikozvino, muna 4.

NASA inotarisira kuregedza iyo International Space Station, ichipa nzvimbo yezvishandiso zvemabhizimusi ega ega. Nzwisisa.
