“Imvula Yesathelayithi” Emangalisayo: IiSathelayithi ze-Starlink LEO ezingaphezu kwama-500 Ezilahlekileyo Ngenxa Yomsebenzi Welanga

Isiganeko: Ukusuka ekulahlekelweni okungacwangciswanga ukuya ekunabeni okukhulu

Ukuqhekeka okukhulu kweesathelayithi ze-LEO zeStarlink akuzange kwenzeke ngequbuliso. Ukususela oko yaqaliswa le nkqubo ngo-2019, ilahleko zesathelayithi zazincinci ekuqaleni (ezimbini ngo-2020), ngokuhambelana namazinga okwehla okulindelekileyo. Nangona kunjalo, ngo-2021 wabona ukunyuka okukhulu (ilahleko ezingama-78), kulandele amanqanaba aphezulu aqhubekayo (99 ngo-2022, 88 ngo-2023). Ingxaki yafikelela kwincopho ngo-2024 ngeesathelayithi ezingama-316 ezitshayo—amanani aphindwe kathathu kwiminyaka edlulileyo—ngokudibeneyo abangela ilahleko ezingama-583, ezilingana nesathelayithi enye elahlekileyo imihla ngemihla okanye enye kwi-15 engayigqibanga umsebenzi wayo.

Umsebenzi Welanga: Ingozi Engabonakaliyo

Uphando lwe-NASA luqinisekisa ulwalamano oluthe ngqo phakathi kokususwa kwesathelayithi kunye nemijikelo yelanga. Ukuqaliswa kuka-2019 kwahambelana nokuncipha kwelanga, kodwa njengoko umsebenzi welanga wawusiya usanda, ukutsalwa komoya kwimijikelezo engama-340-550km kwanda nge->50% ngexesha leenkqwithela ze-geomagnetic. Oku kwenzeka xa:

1. Ukuvutha kwelanga okubangelwa lilanga/ukuphuma kwe-coronal mass kuqhushumba uMhlaba
2. Iimvula ze-geomagnetic zitshisa kwaye zandisa umoya ophezulu
3. Umoya owandisiweyo unyusa ukutsala, okubangela ukubola kwe-orbital

Impikiswano: Iziphepho Ezibuthathaka Zingqina Ukuba Ziyingozi Kakhulu

Ngokuchasene nokulindelekileyo, i-70% yelahleko yenzekile ngexesha leenkqwithela ze-geomagnetic eziphakathi/ezibuthathaka. Ezi ziganeko zinde (iintsuku/iiveki ezihlala ixesha elide) ziyawohloka kancinci kancinci ukujikeleza kwazo ngaphaya kokubuyela kwimeko yesiqhelo, ngokungafaniyo nezivuthuvuthu ezinamandla kodwa ezimfutshane. Umzekelo ophawulekayo: Iisathelayithi ezingama-40 kwezingama-49 zeStarlink ezaqaliswa ngoFebruwari 2022 zahlulwa zizivuthuvuthu ezibuthathaka ezingapheliyo.

Ukutshintshiselana kweMijikelezo ePhantsi

Nangona ii-orbits zeStarlink ezingama-550km zivumela unxibelelwano olune-low latency, ukusondela kwazo eMhlabeni:

1. Inciphisa ubomi bokusebenza ukuya kwiminyaka eyi-~5 (xa kuthelekiswa nokujikeleza kwe-ISS okungama-400km)
2. Imiphumo yokutsala iyanda kakhulu ngexesha le-solar maxima
3. Ibeka emngciphekweni ngakumbi iisathelayithi zovavanyo kwiindawo eziphakamileyo ezingama-210km

Imingeni yexesha elizayo

Njengoko iisatellite zeStarlink ezingaphezu kwama-6,000 zijikeleza ngexesha lokudibana kwelanga—ixesha lembali—izazinzulu zilumkisa ngale nto:

1. Ukuncipha kwesathelayithi okukhawulezileyo
2. Ukuncipha kwe-ozone okunokwenzeka ngenxa yokukhutshwa kwe-aluminium oxide ngexesha lokungena kwakhona kwe-SpaceX kunciphisa ilahleko ngokuqaliswa ngokukhawuleza kokuphinda kuzaliswe kunye neenkqubo ze-deorbit ezenzekelayo, kodwa ukuqina komjikelo welanga kusabalulekile kushishino lonke.

Isiphelo

Esi siganeko sigxininisa ukongamela kwendalo ngaphezu kobuchwepheshe babantu kwaye sigxininisa imfuneko yoyilo lweenkqubo ze-LEO ezibangela iimpembelelo zelanga ezijikelezayo.
