Zvavasina kutaura pamusoro peRussia meteorite

Mushure memazuva angangoita maviri ekubatana nemuongorori wehungwaru kubva kuNational Reconnaissance Office (ONR), timu yenyanzvi iri kusimbisa kuwanikwa kunonakidza zvichibva pane zvavakatora kubva pakadzika pegungwa pakadonha meteorite yeRussia, uyo mushure memashoko ataura kuti yaive chombo cheNorth America; uye kuti yakabatwa ne-anti-missile tekinoroji yevaRussia. Uchishandisa NASA itsva Earth Observation System (SOT) yeNASA -iyo inosanganisira kuunganidza ma satellites anongogara achicherechedza nyika kuti aone kuchinja kwemamiriro okunze, achishandisa nzira dzakajairika dzekuona mafungiro zvino iye zvino-, akawana zvakawanda zvemeteorite pasi pechando pamusoro peLake Shebarkul Lake, mune imwe nzvimbo yakadzika.

Kutsausa, kwakaburitswa pfungwa dzakasiyana, senge dzakaputika mumhepo, uye makarati madiki akaratidzwa izvo hazviwirirane nehukuru hweiyo fireball. Asi timu yekutsvagisa yakwanisa kuona kuti iyo meteorite ine zvipembenene zvisaririra zvakafanana nezvakawanikwa pasi Nguva isati yasimbiswa kuti hupenyu hwepanyika, zvisinei kuwanikwa ndiko chinhu chinodiwa zvikuru neNASA nemamwe masangano, nekuti kuvimbika kwayo kuri kubvunzwa nevanhu vane hunyanzvi vane mazano ekuparadza mamwe madhipatimendi eNASA. .

Vane masayendisiti asina zvematongerwe enyika zvakare akatumirwa kuti atsigire uye aongorore kuwanikwa, zvisati zvawanikwa kuti zvive pachena. Iye zvino, mumwe wevasayendisiti akanyevera nechimwe chinhu chaakaona mumvura yakanyorova yegomba kubva pane iyo meteorite yakabudiswa, uye vasati vanyevera mamwe masayendisiti, akambomiswa nemauto anokosha. Mamwe masayendisiti matatu pamwe chete naRachell Sexton vari kutumirwa kunze kwenheyo kuti vaone kuti gomba rakavharwa kuti ribvise pfungwa.

Kana iwe uchida kuverenga zvakasara, saka hapana chakasara kutenga iyo bhuku nokuti zvakakosha zvikuru rwendo rwakaoma seyandinayo iye zvino.

Bhuku iri rinonzi The Conspiracy, uye munyori waro ndiDhani Brown uye akatengwa mu e-bhuku ne 7 Euros chete.

... Nekukumbira kwekukumbira ruregerero kune avo vaiverenga nemanzwiro mazhinji, heano mhinduro dzakakosha dzeshamwari iyo yakanditumira mibvunzo inobva kure nemusoro wedu uye izvo zvirokwazvo kupwanya tambo yakajairwa yakakurudzirwa nemusoro wenyaya.

Kuswedera kwakadini kwaiva asteroid uye yakaita dambudziko rakawanda sei?

Zvinhu zviviri izvi zvinomiririra njodzi inonakidza yepasi redu, hazvisi zvitsva asi nechinzvimbo chinoitwa nemasvikiro inova yakawanda.

• Munyaya ye asteroid 2012 DA₁₄ nechinhu chiri nyore chekuziva kuti chakapfuura chinhambwe kakapetwa ka13 kupfuura kutenderera kwemwedzi (makiromita 27,700), ingangoita chinhambwe panowanikwa boka renyeredzi satellites inoshanda neGPS yedu ... rinotiudza kuti taive pedyo . Uye tichifunga kuti yaive 45 metres muhupamhi… zvisina basa kutaura.

Asi zvakanaka, isu tinoziva kuti masayendisiti ane unhu hunofadza hwekugona kufanotaura kusvika kweumwe wevadzidzi ava mune ramangwana; akanzwisisa, hongu, kana yaonekwa kuti inouya zvakananga pasi, zvishoma kana kuti hapana chinofanira kuitika panzvimbo yekuiswa kune yakakwirira.

Ndeipi yaiva nengozi yaiva meteorite yeRussia?

• Iyo imwe kesi yakatonyanya kunetsa, sezvo iri mota yekumhanyisa yemamita gumi nemanomwe munzvimbo yayo refu, uye zvinotitora isu nekushamisika. Zvinonzi zvakawanda zvakaita seizvi zvinoitika kazhinji, musiyano ndeyekuti vanowira pedyo nenharaunda dzakagarwa uye zvechokwadi ikozvino inobata basa guru teknolojia iyo inowanikwa kune munhu wese kunyora video, kutora mifananidzo kana kutora mifananidzo yepa satellite.

Zvichida sei kuti tichaona izvi kakawanda?

Hatifaniri kutora hutano hwevanogadzirira, izvi zvinoshamisa zvinowanzoitika.

Chikonzero nei iyi meteorite isina kuonekwa seye asteroid, ndeyokuti hurongwa huzhinji hunoitwa kuti uone zvitunha zvine makiromita anopfuura akaenzana. Nekuona pasi pe mwedzi, tinoshungurudzwa nemhedziso yokuti pasi rinofanira kunge rakange riri chinangwa chemaitiro akawanda zvakare.

Asi pasi rine mamiriro ekunze ekudzivirira kwedu, sezvaungaona mumufananidzo iwowo, kuputika pakukwirira uko kwakaita kuti tisawana mutsindo wekutinhira uye ndiwo wakatyora mahwindo eguta reChelyabinsk iro kusvika ipapo zvakange zvisingazivikanwe nenyika yose; kunyangwe iri mukusahadzika kuti chaive kuputika uku here kana icho chemhedzisiro; nezvavaizofanira kutiratidza gorogo rakakura crater. Asi ngatifungidzirei kuti ingadai yakaputika nekukanganiswa neiyo mamiriro… 9 Hiroshimas pamwe chete ichatiudza imwe nyaya, zvingangoita munharaunda yeUral.

Chimwe chikonzero nei pane zvikanganiso zvishoma zvakanyorwa ndeyokuti zhinji yenyika yakafukidzwa nemvura, iyo yakawanda yemameteorite inowira zvechokwadi; uye vamwe munzvimbo dziri kure.

Sezvo chidzidzo chatadzidza, taifanira kuverenga zvishoma, uye kuziva kuti isu tiri pachena sezvakachengeteka.

Takaoneswa panjodzi dzakawandisa dzakakomberedza kona, kunge mudhudhudhu ari kutirova, achitirova isu takamirira pamagetsi emigwagwa, vezvematongerwo enyika vachiparadza kuchengeteka kwedu ... kuti kana zvanyanyisa kuitika kuti meteorite inowira yakananga patiri. dehenya ... hapana chimwezve chinhu chekufunganya zvekare.

Kwete kunyange mune chikwereti chekadhi rechikwereti, kana kupedzisa chidimbu che master, kana kuti ndiani achaisa pamusoro peshangu dzatakachengetedza kwenguva yakareba.
