Starlink
Startlink ni mkusanyiko wa mtandao wa setilaiti unaoendeshwa na SpaceX, [1] inayotoa ufikiaji wa mtandao wa setilaiti kwa nchi 46. Pia inalenga huduma ya kimataifa ya simu za mkononi baada ya 2023. [2] SpaceX ilianza kuzindua satelaiti za Kiungo cha nyota mnamo 2019. Kufikia Desemba 2022, Kiungo cha nyota ina zaidi ya setilaiti ndogo 3,300 zilizozalishwa kwa wingi katika obiti ya chini ya Dunia (LEO), [3] ambazo huwasiliana na vipitishio vilivyoteuliwa vya ardhini . Kwa jumla, karibu satelaiti 12,000 zimepangwa kutumwa, na uwezekano wa upanuzi wa baadaye hadi 42,000. SpaceX ilitangaza kufikia zaidi ya watumiaji milioni moja mnamo Desemba 2022.
Kituo cha ukuzaji cha setilaiti cha SpaceX huko Redmond, Washington kinahifadhi timu za utafiti, ukuzaji, utengenezaji, na udhibiti wa mzunguko wa Kiungo cha nyota. Gharama ya mradi wa miaka kumi ya kubuni, kujenga, na kupeleka kundinyota ilikadiriwa na SpaceX mnamo Mei 2018 kuwa angalau dola bilioni 10 za Kimarekani. [4]SpaceX inatarajia zaidi ya dola bilioni 30 katika mapato ifikapo 2025 kutoka kwa satelaiti yake, wakati mapato kutoka kwa biashara yake ya uzinduzi yalitarajiwa kufikia dola bilioni 5 katika mwaka huo huo.

Wanaastronomia wameibua wasiwasi kuhusu athari ambayo kundinyota linaweza kuwa nayo kwenye unajimu wa ardhini na jinsi satelaiti hizo zitakavyoongeza mazingira ya obiti ambayo tayari yamesongamana. [7] [8] SpaceX imejaribu kupunguza wasiwasi wa unajimu kwa kutekeleza maboresho kadhaa kwa satelaiti za Kiungo cha nyota zinazolenga kupunguza mwangaza wao wakati wa operesheni. [9] Setilaiti zina vifaa vya kusukuma vya Ukumbi vya krypton ambavyo huziruhusu kuacha obiti mwishoni mwa maisha yao. Zaidi ya hayo, satelaiti zimeundwa ili kuepuka migongano kwa uhuru kulingana na data ya ufuatiliaji iliyounganishwa. [10]
