Kule minyaka mibini idlulileyo, i-spacex ithumele ngaphezulu kwe-950 ye-Starlink Satellites ibe yindawo. Kodwa kwixa elizayo unqwenela ukuthumela izinto ezili-12,000 emhlabeni okanye zinemvume kwiKomishini yoNxibelelwano yoNxibelelwano (i-FCC). Inkampani iya kubhabha iisatellite zesatellite ezikufutshane neenjongo ezilungileyo, kuba ifuna ukubonelela nge-intanethi nakwiindawo ezikude zeplanethi yethu. I-2020 ye-Intellite ye-Interlink yaqala ukusebenza kwimodi yovavanyo kwaye abasebenzisi bokuqala sele bebelane nabanye ngovavanyo lwabo. Kuphela apha i-astronomers kude kakhulu kukonwabela ukubaleka kwesatellite, kuba babonisa ukukhanya kwelanga kwaye bathintele ekufundeni izinto ezikude. Kwaye ukuba i-satellite iya kuba ngaphezulu nangakumbi, abaphandi banokuphoswa yindlela ye-anteroid eyingozi, ethatyathwe nentlekele yehlabathi. Kodwa kutsha nje, i-starlink setellites yaqala ukubonisa ukukhanya okungaphantsi kwaye iphantse ingabonakali ngamehlo. Kweneke ntoni?
I-Starlink ye-Starlink Satellites
I-Spacex kudala yazi into yokuba izazi ngeenkwenkwezi zikhalaza ngakwisatellite yakhe. Ukunciphisa ukubonakaliswa kwesatellite, ekuqaleni kwehlobo le-2020, imizekelo emitsha exhotyiswe ngemingxunya yokhuselo yasungulwa kwi-orbit yomhlaba. Uhlobo olutsha lwesatellites lwabizwa ngokuba yi-Reviessis kunye nobuhle babo buxhomekeke ekubeni ii-viess azivumeli ukukhanya kwelanga ezihlayo kubo kubonakaliswa kakhulu. Ekuqaleni, umbono weNkampani ubonakala ngathi wayethandabuza, kodwa ekugqibeleni yangqina ukusebenza kwayo. Ukucamngca kweesathelayithi kubizwa ngokuba yi-albeo kwaye kutsha nje, izazinzulu zifumanise ukuba emva kokufaka i-visis ezikhuselayo, esi siphithiphithi sehliselwe ngendlela efanelekileyo.
Ushicilelo lwenzululwazi lwesilumkiso seSayensi esabelana ngeendaba ezilungileyo ngokubhekisele kwishishini insider. I-Starlink ye-Starlink ye-Statelink yasungulwa kwi-orbit yendawo ekufutshane nakwisiqingatha sokuqala sika-2019. Ekuqaleni, ezi zixhobo ziwela kubude beekhilomitha ezingama-440, kwaye zibandakanya iinjini zabo kwaye ziphakame ukuya kwi-550-yeekhilomitha eziphakamileyo. Ukusukela ngelo xesha babonakalisa ngokukhanya kwelanga, bekunokwenzeka ukuba ubaqaphele esibhakabhakeni nokuba ngamehlo. Ikhonkco lamasatellite lalibonakala ngokucacileyo eNetherlands kunye ne-Astronomer ye-Marco Langbrook yayikukukwazi ukuyifaka le vidiyo kwividiyo.
I-Starlink Satellites ngo-2019 yabelwa uhlobo "lololiwe"
Funda kwakhona: Ukusetyenziswa kwe-Intanethi ye-Starlink seAtellite eRussia, kucwangcisiwe ukugqiba ukuya kwi-1 yezigidi ruble
Ingozi yokukhanya
Emva kokuqalisa amaqela amaqela eesatellite, uluntu lwezenzululwazi lwaqalisa ukukhalaza ukuba bakwazi ukwenza iingxaki ezininzi. Inyani yile yokuba izazinzulu ezininzi zisusa izinto ezikude zento kwifoto ngokuvezwa kwexesha elide. Iisatellite eziphaphazelayo esibhakabhakeni zishiya imisila "elungileyo" kwaye ixhamla izakhelo. Inani lezixhobo zokwenza i-Intanethi ye-Intanethi liya kwanda kwixesha elizayo, ngoko umngcipheko woko kuphononongwa kwesithuba ngoncedo lweeteleskopu zomhlaba. Ukusebenzisa i-vissots satellites ngenxalenye yepesenti yomngcipheko - isatellites ngoku ayibonakali ngamehlo. Kodwa i-spacex isafuna ukubaphucula, kuba zikwadala iingxaki zeastronomers. Yiyo loo nto i-Astronon kaJonathan McDowell ibiza impumelelo entsha ye-spacex "uloyiso, kodwa ungaphelelanga."
Njengoko ubona, i-spacex izama ukuya ngandlel 'ithile ingxaki. Kodwa emva kwako konke, kukho ezinye iinkampani kwihlabathi elifuna ukuqhuba i-Intanethi yabo ye-satellite. Ukuphunyezwa kwezikhala ezifanayo kudala babandakanyeka kwi-TheBEBEB, kwaye kutsha nje kwaziwa ukuba iAmazon ifuna ukujoyina lo mbutho. IsiCwangciso seGW CHW siCwangciso sokuqalisa umjikelezo weplanethi yethu kangangeesatellite ezili-13 000, kwaye ayikacaci, baya kuncitshiswa ngamathenteli akhuselayo, okanye hayi. UJonathan McDowell, okhankanywe apha ngasentla, ukhathazekile malunga nento yokuba ezinye iinkampani ezifana ne-Owebeb bafuna ukuthumela amaqabane abo kwi-orbit ephezulu. Kwaye oku kuthetha ukuba banokuphazamisa umsebenzi wesatellite. Kodwa oku akufanelanga nje kuphela ukuba izazinzulu aziyi kufunda indawo. Kuya kufuneka babeke esweni intshukumo ye-asteroids, enye kwixesha elizayo inokubhabha kumhlaba wethu. Ukuba awuziboni ngexesha kwaye ungathathi inyathelo, intlekele yenzeka.

Kwaye ayisiyiyo ihlaya, kuba ii-asteroids zinokuba yingozi kwiPlanethi yethu ikho. Omnye wabo u-AUPHIK, osandula ukutshintsha umkhondo wentshukumo yakhe kwaye usondele emhlabeni nge-13 ka-Epreli, 2029. Ngokobalo lweenzululwazi, iya kubhabha kumgama oziikhilomitha ezingama-29,470 ukusuka kumphezulu weplanethi yethu. I-rappirochement elandelayo ye-asteroid kulindeleke ukuba ku-2036 kwaye izazinzulu azisacaci indlela eya kuba yingozi. Ulwazi oluthe kratya malunga nokuba kutheni into yendawo yendawo icime indlela yokuqala, unokufunda kule nto.
