<prompt> Pfupisa nyaya yacho: NASA yakanga yasarudza basa rine vavariro huru rokushanyira kometi ndokubvisa dombo kubva pamusoro payo kuti vagadzire nzvimbo inotenderera nokuda kwavafambisi vengarava dzomuchadenga. Ngarava yerobhoti. ichabvisa dombo guru paasteroid ndokurikandira kumativi ose. emwedzi, ichiva nzvimbo yokugadzirira mishoni dzomunhu dzomunguva yemberi kuMars, sangano romuchadenga reU.S. rakazivisa kudaro. Inonzi Asteroid Redirect Mission inofungidzirwa kuti inodhura inenge 1.25 bhiriyoni isingabatanidzi mari yokutanga uye inotarisirwa kuti itange muna December 2020. Yaizoteverwa makore mashanu gare gare nenzendo dzevanhu kuenda kudombo romuchadenga, chinjo yechirongwa chakarongwa naPurezidhendi Barack Obama muna 2010. Dzorera pasi kuti uone vhidhiyo. NASA inoronga kutora dombo rinobva kuasteroid huru rinoratidzwa richishandisa ngarava yemarobhoti. Ichabva yaendeswa kunzvimbo inenge ichitenderera mwedzi, uko ichadzidzwa nevafambisi vengarava. NASA yakarangarirawo kuisa muhomwe asteroid duku ndokudzorera muviri wose kumugwagwa wakakwirira wakapoteredza mwedzi. Pashure pokufunda kwakadzama, NASA yakasarudza kuunganidza ndokutamisa dombo, basa richaita mari inenge mamiriyoni 100 akawanda, asi iro rinogadzirira zviri nani sangano nokuda kwechinangwa chokupedzisira chokumhara vafambisi vechadenga paMars. Ivo rudzi rwezvinhu zvatinoziva kuti tichada. apo tinoenda kune mumwe muviri wepuraneti, NASA Associate. Mutungamiri Robert Lightfoot akaudza vatori venhau pamusangano. NASA inoronga kudzidza asteroid yacho kweanenge gore uye kuedza mitoo yokutsauka iyo rimwe zuva ingadikanwa kuponesa. Pasi kubva pakurovera kungagona kuva kunoparadza. Imwe asteroid kana kuti. comet yakarovera papuraneti makore anenge mamiriyoni 65 akapfuura,. zvichitungamirira kukuchinja kwemamiriro okunze kwakauraya madinosaurs uye. zvimwe zvipenyu zvakawanda zvePasi panguva iyoyo. Kusvikira pari zvino, NASA ine mapuraneti matatu anobvira, asi haitariri kuita chisarudzo pamusoro pokuti ndiani achabhururuka pamberi pa 2019. Basa racho rinobatanidza kubhururuka kwechikepe chomuchadenga chine robhoti, chinofambiswa nemagetsi ezuva, kuenda kuasteroid nokuda kwokunzvera kukuru. Kamwe dombo rinonangidzirwa rakasarudzwa, muedzo waizofamba uchienda pasi kunzvimbo yacho ndokutambanudza...  <response>: Ngarava yomuchina yeNASA ichabvisa dombo guru paasteroid. Ichashanyirwa navafambisi vechadenga vari mungarava yomuchadenga yeOrion. Vafambi vokudenga vaizodzidza asteroid ndokutora mienzaniso. Zvichaedza unyanzvi hutsva hunodikanwa nokuda kwebasa rokupedzisira kuMars.
