Awa ndi malingaliro omwe akuyenera kutsatiridwa ndi NASA ngati asteroid igunda Dziko Lapansi

NASA

Mpaka lero chowonadi ndichakuti Dziko lapansi lawopsezedwa kwambiri kuposa momwe mungaganizire. Kusiya kuwonongeka komwe anthu akubweretsa padziko lapansi kapena kuti mtundu uliwonse wankhondo zapadziko lonse lapansi zitha kuchitika nthawi iliyonse, pali zinthu zakunja zomwe tiyenera kuziganizira ndikuti, ngati sitinakonzekere, zitha. kwenikweni ndi moyo wapadziko lapansi.

Izi ndizomwe gulu la asayansi a NASA akhala akugwira, pulojekiti yomwe kuthekera kwakukulu kwakuti dziko lathuli litha kugundidwa ndi asteroid kuli kuphunzira. Izi, monga momwe mungaganizire komanso bola ngati asteroid ili ndi kukula ndi misa, zitha kutanthauza kuti pamapeto pake chilichonse chamoyo chimatha kufa, chifukwa chake NASA yatenga ntchitoyi mozama kwambiri kuposa momwe mungaganizire.

asteroid

Ateroid yayikulu imatha kugwa padziko lapansi

Kuti timvetse bwino izi ndikufuna kuti tiwone pang'ono pamutuwu. Nthawi ino ndilankhula za zomwe zidachitikadi, monga zotsatira mu 2013 za asteroid mdera la Chelyabinsk (Russia). Kuti tipeze lingaliro, tikulankhula za asteroid pafupifupi 19 mita mulifupi. Ngakhale izi, zomwe zidakhudzidwa zidakhudza anthu opitilira 1.200 ndikuwononga nyumba zomwe zinali pamtunda wa makilomita 150 kuchokera komwe asteroid idagwera pansi.

Potsatira chitsanzo ichi, chomwe chili ndi zolemba zambiri pa intaneti, ndikukuwuzani kuti lero zapezeka zoposa zinthu 8.000 zoyandikira dziko lathu lapansi zokhala ndi mita zopitilira 140. Iliyonse mwa ma asteroid awa, ngati ingakhudze Dziko Lapansi, itha kukhala ndi kuthekera kokwanira kuchotsa dziko kukula kwa Spain pamapu. Pomaliza, ndikuuzeni kuti zinthu 8.000 zokha, malinga ndi kuwerengera, zimangokhala gawo limodzi mwa magawo atatu azinthu zomwe zimasokoneza Dziko Lapansi.

kulowa kwa asteroid

NASA yakonza lipoti lofotokoza njira yakutsogolo kuti athe kupulumuka pazovuta zamtunduwu

Chifukwa cha izi, sizosadabwitsa kuti NASA, mothandizana ndi Federal Emergency Management Agency, onse awiri mabungwe aku United States, adalemba lipoti losonyeza magawo asanu a ntchito zomwe zichitike mzaka khumi zikubwerazi.

Sinthani kuthekera kwazinthu zapafupi-Earth

Cholinga choyamba chokhazikitsidwa ndi NASA kuti apulumuke chifukwa cha asteroid yayikulu chimaphatikizapo kupanga ukadaulo watsopano womwe umatipatsa njira yofulumira komanso yodalirika yodziwira gulu la zinthuzi. Masiku ano zowonera monga Catalina Sky Survey kapena Pan-STARRS1 telescope ndizoyang'anira ntchitoyi.

Sinthani kuneneratu kuti chimodzi mwazinthuzi chidzafika Padziko Lapansi

Mfundo yachiwiri yomwe NASA ikulimbikira kuti ntchitoyi iyambe ndikuwongolera zoneneratu ndi zothekera zomwe zimagwira ntchito ndipo zomwe zimatiuza za nthawi yomwe chimodzi mwazinthuzi zitha kugunda Padziko Lapansi. Pofuna kugwira ntchitoyi, cholinga chake ndikukulitsa mgwirizano pakati pa mabungwe osiyanasiyana pankhaniyi.

Pezani njira zopotozera mayendedwe a asteroid

Monga mfundo yachitatu, chiwopsezo chikapezeka, NASA idanenanso kuti tiyenera kufotokoza momveka bwino momwe tingasokerere asteroid. Mwanjira imeneyi, NASA yakhala ikugwira ntchito ngati yotchedwa Asteroid Redirection Mission, yomwe mwachiwonekere inali imodzi mwa zomwe zidachotsedwa mu 2017 ndi oyang'anira a Trump. Kuti tichite ntchito yongoganizira ngati iyi NASA zawonetseratu kuti zombo zouluka ziyenera kugwiritsidwa ntchito popanda woyenda aliyense yemwe akukwera.

Mgwirizano wapadziko lonse lapansi ungakhale wofunikira

Mgwirizano wachinayi wa NASA padziko lonse lapansi. Ngati mwanjira imeneyi tikunena mawu a Aaron Miles, mlangizi ku Office of Science and Technology Policy ya White House: "ndi ngozi yapadziko lonse lapansi kwa onse, ndipo njira yabwino yothanirana ndi zoopsayi ndi mgwirizano."

Dongosolo ladzidzidzi liyenera kupangidwa

Monga mfundo yomaliza yachisanu, NASA yapempha boma la United States kuti lipange dongosolo ladzidzidzi lomwe liyenera kukhazikitsidwa mosayembekezereka kuti asteroid ikamenya Dziko Lapansi. Dongosololi likhoza kufanana ndi zomwe zidalipo kale pamavuto ena achilengedwe omwe, mwatsoka, tikuwoneka kuti tidazolowera.


Zomwe zili m'nkhaniyi zikutsatira mfundo zathu za malamulo okonzekera. Kuti mufotokoze cholakwika dinani Apa.
