Njengoko ubantu besilunga ukubuyisela eLoliwe kunye ne-Artemis program, umcimbi onzima wezoqala akhoyo — ixesha kuLoliwe ngubani? Ngo-Epreli 2, 2024, uMkhuluwe weNdlu yamaMelika wokwazi nokwenkolo wemicimbi yomsakazo (OSTP) woqala NASA ukusimisela iXesha Elinxulumene neLoliwe, okanye i-LTC, ngaphambi kokugqibela kuka-2026.
Nani iLoliwe ifuna ixesha lakwayo
Kwihlabathi, sisesisebenza iXesha Lokushintshwa Kumhlaba (UTC), esisikwanqobileyo elingamashumi amane kunye neyisixuko kunye namagrafu eqela laseKhaya. Izikhundla ze-GPS, izinqubo zolwandle, izikhundla zemandla, kunye nesizwe sonke zisesisebenza kunye neXesha Lokushintshwa Kumhlaba.
iLoliwe ibonisa umcimbi onzima. Ngenxa yokuba ubunzima beLoliwe bumaqala kancinci kunobunzima bamaKhaya, inkqubo yokudengeza ipredikta iiwotshi ekukhangelijweni kweLoliwe zihamba ezilandeleni ezi-56.02 zomikrosekhe ngosuku. Oku kunqubo — ezikhulikiweyo ngenzela kaAlbert Einstein — kusikhudu yokuba uguqwa umhla kwiLoliwe ifanele iloliwe clock ise ngesikhathi esikhulu.
Ngolumdla lowexesha, umikrosekhe ongu-56 angase abe lilungu. Lowo yondulela, isiqalo somjikelo sibhekisa isikhundla sephesheya ezigidi zemisikela ngosuku. Ngomhla, iimpilo azakuba ezikhundla ezi-500 — ayafanela izikhundla-zokubeka kwisizwe kunye nenyuxuma ye-rover kunye nexixesha lokunxibelelana neyuleliswe-zika.
Isenziwa njani i-LTC
iXesha Elinxulumene neLoliwe iyokhiwe kumlobi oweyonke wama-UTC luliphakimiyiweyo ekukhangelijweni kweLoliwe. Uhlelo luhlanganisa i-network yeewotshi ze-atom kubethw'alunye eLoliwe kunye no-orbital. Ezi wotshi ziyosebenza njengeza iXesha eloliwe ekusisekwile, okufanele iXesha e-UTC esentla kumhlaba.
iXesha Elinxulumene neLoliwe iyoba nekixesha elifanelekileyo efanikileyo ne-UTC ukuze ixesha lisisiwe ngokunyamela phakathi koMhlaba kunye neLoliwe. Isiphumo esinqumbi sibhekisa kumjikelo wexesha otshintshiwe — isiphumo somjikelo esichazwe iLoliwe iwotshi ibaleka ngokukhawuka.
iNzuzo yabantu abakwazi nokwazi (NIST) yashicilela i-ihlelo lwezibalo ngo-Agasti 2024 esichaza imodeli yezibalo yokufilikeza umjikelo wexesha owesazo utshintshiwe.
Umzobo Wentando wehlabathi
iXesha lokusiphumo kweLoliwe ayinomsebenzi weNASA kuphela. i-Iqela leLungu Lomhlaba leNkqubo eZingezeleleyo zeNtombazane yeHlabathi (ICG) yasimisela iqela elikhethiweyo ngo-2024 ukulawula ixesha leLoliwe kunye nobusiqalo. I-Artemis Accords — intsayini zama-50 ihlanu — ivuma ikhuselo yeenguqu ezisongeleneyo eLoliwe — ixesha elinxulumene ngenxa yayo.
iBESET Earth Space Agency (ESA) nayo yaye ifunyenwe ixesha loLoliwe njengecandelo lebhuloŝ likhoyo-kwizixeko kumbono wehlabathi, esibonela izikhundla zekunxibelelana kunye nesizwe eLoliwe.
Ngubani i-LTC Eloliwe
iXesha elinxulumene neloliwe iyofakela into enkonko — indawo entsha yexesha eloliwe kunye nesinqumo sabantu ezintlanganiso, ikomyunikeyshen ezikhethiweyo phakathi koMhlaba kunye neLoliwe, kunye no-eventual wamathuba ekubethw'ixesha kuMarasi kunye nobunye.
iXesha loLoliwe ekusisekwileyo moontimenow.com kusetyenziswa isiqalo somjikelo sowesazo +56.02 zomikrosekhe ngosuku, umnikelile-longe kwi-J2000.0 epoch, ukulungela oku umxulumane weLanga-base iwotshi ibaleka ngoku.
