Kana tichitaura nezve nyeredzi uye kushanya kwemuchadenga, zvinogona kutaurwa kuti matanho ekutanga akatorwa munguva pfupi yapfuura. Uye pane gakava rakakosha kwazvo pamusoro pekuti muchadenga chekunze chinotangira papi uye kuti vanhu vese vakabhadhara kuti vaone nyika vari muchitundumeme vanogona kunzi vazivi vemuchadenga here. 733m6m
Muchokwadi, kuti tipindure mubvunzo uyu, zvakakosha kuti unzwisise zvakawanda nezve Kármán Line uye chinonyanya kukosha: ndiani wawakabvunza mubvunzo uyu? Mhinduro yacho inogona kusiyana-siyana, uye nyanzvi dzezvenyeredzi dzinoramba dzichiedza kusarudza kuti kunze kunotangira kupi. Nzwisisa nyaya yacho zvachose.
Chii chinonzi nzvimbo? 50j5i
Nzvimbo yekunze, kuwedzera kune mapuraneti atinotoziva, zvakare ine asteroids, comets, nyeredzi, meteoroids uye Earth satellite. NASA, kubva kumakambani akadai Starlink nemamwe makambani anoshandisa midziyo iyi kupa masevhisi.
Pane gakava rakasiyana-siyana pamusoro pemuganhu uri pakati pemhepo yakapoteredza pasi nechadenga, asi nyanzvi dzinobvumirana pamutsara mumwe chete: ichi chikamu chechadenga chinotanga chaizvoizvo apo munhu anobva mumhepo yakapoteredza pasi redu.
Asi sezvo pasina rudzi rwemutero kana muganhu unooneka unotizivisa kuti munhu ari kunze muchadenga mukati merwendo, zvakaoma chaizvo kuita tsananguro iyi. Asi Theodore von Kármán, injiniya nenyanzvi yefizikisi yokuHungary neAmerica, akatotaura panotangira nzvimbo uye zvidzidzo zvake zvichiri kukurukurwa nanhasi.
The Kármán Line 5z1y26
Zvekuva mumwe wenyanzvi dzakabatsira zvakanyanya kwatiri kuziva kwainotangira nzvimbo yekunze, Theodore von Kármán akasarudza kuti ndege dzose pamusoro 80 km pamusoro pegungwa inogona kunzi ndeyemuchadenga.
Pazasi peizvi, vanhu vese vakaita rwendo pasi pemuganhu waitsanangurwa nainjiniya havana kutorwa sevazivi vemuchadenga uye rwendo rwacho aeronautics, panzvimbo penzvimbo.
Zvisinei, iyo National Oceanic uye Atmospheric istration kubva kuUSA (NOAA ou GORE) inofunga kuti Kárman Line inowanikwa 100 km pamusoro pegungwa. Muganhu uchiri kushandiswa ne International Aeronautical Federation (FAI) senzira yekusarudza kuti ndipo panotangira nzvimbo yekunze.
Tsanangudzo itsva 5v4i5v
Zvakakosha kuti tinzwisise kuti zvinhu zvese pazvaitsanangurwa kuma1990, takanga tisina ruzivo rwakanyanya nezvemapuraneti, maburi matema nenyeredzi. Tichifunga izvi, Jonathan McDowell, ye Harvard-Smithsonian Center yeAstrophysics, akadzokorora macalculations e Karman's Line kuti uone kana kuverenga kwacho kuchingangove kuchiri kutariswa zvechokwadi kana kana paine shanduko ichifanira kuitwa.
Ne data kubva kundege munzvimbo dzekunze kubva ku43 zviuru zvesatelliti, mcdowell akabva aziva kuti mhando dzinodarika muganhu wemakiromita makumi masere pamusoro pegungwa dzine mukana wakaderera wekudzokera kupasi redu. Hwaro hwezviverengero izvi hwaive hwakaderera pane satellites 'orbit, inonzi perigee. Nyanzvi yezvemuchadenga yakakwanisawo kunzwisisa kuti kana masatellite ari pamusoro pemakiromita makumi mapfumbamwe nemapfumbamwe pamusoro pegungwa, mukana wekuti vadzokere kuPasi wakadzikira zvakanyanya.
Iwe hausi kuona ma satellites asvika 112 mamaira odzoka. Iro muganhu wakanyatsotsanangurwa, muganhu une muganhu wakanaka, unoenda kubva pasi peperigee kusvika kune imwe nzvimbo iyo isingachakwanisi kudzoka.

Saka, mcdowell ichange ichitungamira gakava kuitira kuti vanhu vakawanda vari munharaunda yezvenyeredzi vape pfungwa dzavo uye muganhu ugotsanangurwa. Zvisinei, kune nyanzvi dzinobva kune dzimwe nyika dzisingabvumirani nekukosha kwemakiromita makumi masere pamusoro pegungwa.
Space limit maererano neChina 5e6h3w
A China ine pfungwa dzayo pachayo maererano nepanotangira kunze. Chimwe chazvo ndechekuti kana setiraiti iri kubhururuka pamusoro pemakiromita 88 pamusoro pegungwa, inenge yatove munzvimbo imwechete nemapuraneti, kometi nenyeredzi.
Nekudaro, kana chirongwa chako chiri pakakwirira pamusoro pemakiromita makumi mapfumbamwe nematanhatu pamusoro pegungwa, nyika inonzwisisa kuti uri kuita hutsinye hwemauto uye pachave nematambudziko. Mukupera kwegore rapfuura, nyika yeAsia yakasangana neUnited Nations (onu kutsamak) kutaura kuti satellite Starlink-1095 yakapotsa yadhumhana nechiteshi chemuchadenga tiangong-3 da China. Vemuchadenga vekuChina vaifanira kutsaudzira kaviri kudzivirira tsaona kuti isaitike.
kunyangwe Outer Space Chibvumirano dzakasainwa nenyika dzinoverengeka dziri chikamu che onu kutsamak, mumwe China inotaura kuti masatellite e Starlink inogona kuva dambudziko kune dzimwe nyika nemakambani. Izvi zvinodaro nekuti hapasati pave neanotariswa neAmerica kuona kuti makambani anobva kunyika yeAmerica haakonzere tsaona muchadenga. Zvakanga zvakakodzera kuti NASA uye Starlink vakaita chibvumirano kuitira kuti matambudziko arege kuitika.
Muchokwadi, kunyangwe paine hurukuro yese, hapasati pave negwaro rinotonga uye rinoda kuti kuongororwa kuitwe nenzira isina kwayakarerekera. A onu kutsamak yakauya kuzoita musi waNdira 27, 1967 pakusikwa kwe Outer Space Chibvumirano iyo, kunze kwekusarudza mimwe mitemo, yakavimbisawo kuti hapana muviri wekudenga unogona kuva nemuridzi, pasinei nokuti mumwe munhu akaedza sei kutengesa.
Asi tichine zvakawanda zvekusarudza: nemakambani ari kutodyara mari mukushanya kwemuchadenga uye nzendo dzekutanga dzekutengesa kunzvimbo zvakare dzatove kuitika, iyo yekuvandudza inopfuura kudikanwa.
Muganho wenzvimbo maererano neNASA 3p2853
Muchokwadi, hapana mutemo kana kunyora mune chero chinyorwa chenhoroondo chinopindura uyu mubvunzo. Mhinduro yacho inogona kutsanangurwa semakiromita makumi masere pamusoro pegungwa, sezvo Federal Aviation istration, iyo US Air Force, NOAA uye NASA shandisa nhamba iyi sehwaro hwezvidzidzo zvavo.
Parizvino, the Karmán Line iri makiromita makumi matanhatu nemaviri kubva pamutsetse wegungwa uye izvi zvinogona kutariswa sehwaro hwemusoro wenyaya yerugwaro urwu, sezvo NOAA inotora chikamu ichi chechadenga semuganhu pakati pemhepo yePasi uye kunze.
Zvisinei, iyo NASA Mission Control Center inotarisawo kureba kwemakiromita zana nemakumi maviri nemaviri sechikonzero chekutsanangura matangiro ekunze kwechadenga, chaizvo nekuti "panguva ino ndipo panoonekwa kukweva kwemhepo".
Kunyora kwakaitwa na Bhavya Lal e Emily Nightingale do Institute for Science uye Technology Policy panguva yekuongorora mabhuku muna 2014. Zvakaoma kutsanangura muganhu nokuti hapana muganhu unooneka. Sezvo pasina kuwirirana panhaurirano iyi.
Zvinotaurwa nevazivi venyeredzi veNASA 1j3243
Pasinei nekudzidziswa uye kusarudzwa kwakasimba kunofanirwa kutorwa semushandi we NASA vanoenda muchadenga, vazivi vemuchadenga vanobvuma kuti kunyangwe avo vakabhadhara kuti vafambe, pane avo vanosiya nyika kune basa rekuongorora, anokodzerawo zita rimwe chetero. Wese munhu anoziva kuti vanhu vanofarira nzvimbo yekushanya vari munzvimbo iyoyo nekuti vakaribhadharira uye ivo havasi (uye havafanirwe kuve) kuvhiringika nemukuru wemauto akapedza makore mukudzidziswa.
Ndinofunga kana ukayambuka mutsara, unonyatsokodzera semuchadenga, pasina kupokana. Zvakawanda, zviri nani.
Terry Virts, aimbove mutungamiriri weInternational Space Station iyo yaive iri munzira kwemazuva 213
Izvi zvinoratidza pfungwa yekuti kana rimwe zuva ukatora rwendo kuenda muchadenga uye chitundumeme chikapfuura kureba kwemakiromita zana pamusoro pegungwa, unogona kutorwa semuchadenga. Zvakare, usafunge kuti chokwadi chekuti hausi mugwara hachikukodzeri iwe semuchadenga.
Alan shepard e Gus Grissom, vakaita kubhururuka munzvimbo ye-sub-orbital yechadenga uye vachifunga nezvemutemo uyu, havangave vazivi venyeredzi. Asi chokwadi chekuve muchikepe uye kupfuudza muganhu unoshandiswa nemasangano sechigadziko chinopfuura zvakakwana kugamuchira zita racho.
Unofungei nezvemiganho iripo yekunze yekunze inocherechedzwa nemasangano ane hunyanzvi? Tiudze mashoko!
