<prompt> Fingqa isihloko: I - NASA yayikhethe umsebenzi wokuvelela ozohambela i - comet futhi ikhiphe idwala ebusweni bayo ukuze yakhe isizinda esizungezayo sabathwebuli bezinkanyezi. Umkhumbi oyirobhothi. uzokhipha idwala elikhulu kuyi - asteroid bese uliphonsa nxazonke. zenyanga, ube yindawo yokulungiselela ukuthunyelwa kwabantu esikhathini esizayo eMars, kwembule i - U.S. space agency. Lokhu okubizwa ngokuthi i-Asteroid Redirect Mission kulinganiselwa ukuthi kubiza cishe amaRandi ayizigidi eziyizinkulungwane ezingu-1,5 ngaphandle kwezindleko zokuyethula futhi kuhloswe ukuba kuhanjiswe ngoDisemba 2020. Ngemva kweminyaka emihlanu kwakuzolandelwa uhambo lwabantu oluya edwaleni lasemkhathini, ukuguqulwa kohlelo olwaluhlongozwa uMongameli uBarack Obama ngo-2010. Skrolela phansi ukuze ubone ividiyo. I - NASA ihlela ukuthatha idwala elisuka kuyi - asteroid enkulu elibonisiwe isebenzisa umkhumbi oyirobhothi. Khona - ke iyothathwa iyiswe emzileni wenyanga, lapho iyotadisha khona osomkhathi. I - NASA nayo yacabangela ukufaka i - asteroid encane esikhwameni futhi. ukuhambisa umzimba wonke emzileni ophakeme ozungeze inyanga. Ngemva kokucwaninga kabanzi, i - NASA yakhetha ukuqoqa nokuthutha. idwala, umsebenzi oyobiza cishe izigidi ezingu - 100 zamaRandi ngaphezulu, kodwa. olungiselela kangcono inhlangano umgomo wokugcina. wokwehla kosomkhathi eMars. Lolu uhlobo lwezinto esaziyo ukuthi sizodinga zona. lapho siya komunye umzimba weplanethi, kusho i-NASA Associate. Umphathi uRobert Lightfoot utshele izintatheli engqungqutheleni. I - NASA ihlela ukutadisha i - asteroid cishe unyaka bese ihlola amasu okuphambukisa okungenzeka ngelinye ilanga kudingeke ukuba siwalondoloze. Umhlaba ngenxa yokushayisana okungase kube inhlekelele. I-asteroid noma. i-comet yashayisa iplanethi cishe eminyakeni eyizigidi ezingu-65 edlule,. okwaholela ezinguqukweni zesimo sezulu ezabulala ama-dinosaurs kanye nezinye izinto eziningi eziphilayo eMhlabeni ngaleso sikhathi. Kuze kube manje, i - NASA inezinkanyezi ezincane ezintathu ezingase zibe khona, kodwa ayilindele ukuthatha isinqumo ngokuthi izondizela kuphi ngaphambi kuka - 2019. Lomsebenzi uhilela ukundiza umkhumbi-mkhathi oyirobhothi, onikwe amandla yi - solar electric propulsion, uye kuyi - asteroid ukuze kuhlolwe kabanzi. Lapho sekukhethiwe itshe eliyinhloko, iphenyo lalizokwehla liye ebusweni bese lisebenzisa...  <response>: Umkhumbi-mshini we-NASA uzosusa itshe elikhulu elisemkhathini. Kuzovakashelwa osomkhathi abasemkhunjini wesikhala i-Orion. Izazi zezinkanyezi zazizofunda i - asteroid futhi ziqoqe amasampula. Kuzohlolwa ubuchwepheshe obusha obudingekayo ohambweni oluya eMars.
