Eminyakeni emibili edlule, i-Spacex ithumele ama-satellite angaphezu kwama-950 e-Starlink emkhathini. Kepha esikhathini esizayo uhlose ukuthumela izinto eziyi-12,000 eziya eMhlabeni u-Ortibit futhi sekuvele kunemvume evela ku-Federal Communications Commission (FCC). Le nkampani izontanta ama-satellite aseduze-se-satellite ngezinhloso ezinhle, ngoba ifuna ukunikeza i-Intanethi ngisho nezindawo ezikude kakhulu zeplanethi yethu. I-2020 Satellite Internet Starlink yaqala ukusebenza kwimodi yokuhlola futhi abasebenzisi bokuqala sebehlanganyele izibuyekezo zabo. Laphana kuphela lapha kuphela okukude nokukujabulela ama-satellite agijimayo, ngoba akhombisa ukukhanya kwelanga futhi akuvikele ekutadisheni izinto ezikude endaweni. Futhi uma ama-satellites ezoba ngaphezulu kakhulu, abacwaningi bangaphuthelwa indlela ye-asteroid eyingozi, egcwele inhlekelele yezwe. Kepha muva nje, ama-satellink e-starlink aqala ukukhombisa ukukhanya okuncane futhi acishe abonakale esweni elinqunu. Kwenzenjani?
Ama-satellite amasha we-Starlink
I-Spacex kudala yaqaphela ukuthi izazi zezinkanyezi zikhononda ngama-satellite akhe. Ukuze unciphise ukuboniswa kuma-satellite, ekuqaleni kwehlobo lika-2020, amamodeli amasha afakwe ngemibono yokuvikela yethulwa e-Orbit. Uhlobo olusha lwe-satellites lwabizwa ngokuthi i-viseorsat futhi ubuhle bawo bonke busekuqiniseka ukuthi imibono ayivumeli ukukhanya kwelanga okuwa okubonakala ngokuqinile. Ekuqaleni, umbono wenkampani wawubonakala ungabaza, kepha ekugcineni wakufakazela ukusebenza kwawo. Ukuthambekela kwama-satellites kubizwa ngokuthi i-albedo futhi muva nje, ososayensi bathole ukuthi ngemuva kokufaka imibono yokuvikela, le nkomba yehle ngokubonakalayo.
Uhlelo lwesayensi lwesaziso sesayensi sabelana ngezindaba ezinhle ngokubhekisele ku-Insider yebhizinisi. Ama-satellite okuqala we-Starlink athulwa e-orbit esondelene nengxenye yengxenye yokuqala ka-2019. Ekuqaleni, la madivaysi awela ekuphakameni kwamakhilomitha angama-440, bese kufaka phakathi izinjini zawo futhi akhuphuke ku-550-Kilometer Heights. Kusukela ngaleso sikhathi babonisa ngokuqinile ukukhanya kwelanga, kungenzeka ukubabona esibhakabhakeni ngisho nangeso elinqunu. Uchungechunge lwama-satellites lwabonakala ngokusobala ngaphezu kweNetherlands kanye ne-Astrometer of Marco Langbrook yakwazi ukuthwebula le nto kuvidiyo.
I-StarLink Satellites ngonyaka we-2019 yakha uhlobo "lwesitimela"

Ingozi yokungcoliswa kokukhanya
Ngemuva kokwethula amaqembu amaningana ama-satellite, umphakathi wesayensi waqala ukukhononda ukuthi angakha izinkinga eziningi. Iqiniso ngukuthi ososayensi abaningi basusa izinto ezikude zesikhala esithombeni esivezwa isikhathi eside. Ama-satellites andiza esibhakabhakeni ashiya ukukhanya okude "imisila" futhi aphanga ozimele. Inani lamadivayisi wokwakha i-Intanethi Yomhlaba lizokwanda ngokuzayo, ngakho-ke ubungozi bokuthi ucwaningo lwesikhala ngosizo lwezibonakude zomhlabathi ngeke lungenzeki. Ukusebenzisa ama-Vissat Satellites ngokwengxenye kunciphise iphesenti lengozi - ama-satellite manje awabonakali esweni elinqunu. Kepha i-SPACHX isadinga ukuthuthukisa yona, ngoba isakha izinkinga ezithile zezazi zezinkanyezi. Kungakho u-Astronon Jonathan McDowell wabiza impumelelo entsha yeSpacex "Ukunqoba, kepha akaqedi."
Njengoba ubona, i-Spacex izama ngandlela thile ukuyixazulula inkinga. Kepha ngemuva kwakho konke, zikhona ezinye izinkampani emhlabeni ezifuna ukusebenzisa i-inthanethi yazo ye-satellite. Ukuqaliswa kwemibono efanayo sekuyisikhathi eside kubambisene ne-Oneweb, futhi muva nje kwaziwa ukuthi i-Amazon ifuna ukujoyina lo mjaho. Uhlelo lwe-Chinese GW Plan lokuvula umjikelezo womhlaba wethu ongama-satellite ayi-13,000, futhi akukacaci, azohlonyiswa ama-satellite avikela, noma cha. UJonathan McDowell, okukhulunywe ngaye ngenhla, naye ukhathazekile ngeqiniso lokuthi ezinye izinkampani ezinjenge-thileeb zifuna ukuthumela abangane bazo ku-orbit ephakeme. Futhi lokhu kusho ukuthi bangaphazamisa umsebenzi we-satellites yesikhala. Kepha lokhu akugcini nje ngokuthi ososayensi ngeke bakwazi ukufunda isikhala. Badinga futhi ukuqapha ukunyakaza kwama-asteroid, omunye wawo esikhathini esizayo angandiza abheke kwiplanethi yethu. Uma ungaziboni ngesikhathi futhi ungathathi isenzo, kungenzeka ukuthi inhlekelele yenzeka.
Uma unesifiso sezindaba zesayensi nezobuchwepheshe, bhalisela isiteshi sethu se-telegraph. Lapho uzothola izimemezelo zezindaba zakamuva zesayithi lethu!
Futhi lokhu akulona ihlaya, ngoba ama-asteroid angaba yingozi ukuthi iplanethi yethu ikhona ngempela. Omunye wabo u-apofish, osanda kushintsha umkhondo we-trajectory wokunyakaza kwakhe futhi asondele emhlabeni ngo-Ephreli 13, 2029. Ngokwezibalo zososayensi, kuzondiza ibanga lamakhilomitha angama-29,470 ukusuka ebusweni bomhlaba wethu. Ukuvikelwa okulandelayo kwe-asteroid kulindeleke ngo-2036 kanti ososayensi abasakacaci ukuthi lo mcimbi uzoba yingozi kangakanani lo mcimbi. Imininingwane engaphezulu yokuthi kungani into yesikhala icishwe ngokuzumayo indlela yokuqala, ungayifunda kulokhu okuqukethwe.
