Artemis II — Anthu Akubwerera ku Mwezi
Oyang'ana ubwiyunge woyamba wa akatswiri m'maka 50 yapita
Magawo a Mwezi Lero
Coordinated Lunar Time (LTC)
Mwezi pa Malo Anu
Nthawi Padziko Lonse
Mwezi wa Lero
Gawo la mwezi lathawichi ndi Mwezi Woyandikira ndi kuwala kwa 94.6%, pa lunali 16.4 la kupita la 29.53-day synodic cycle. Mwezi ali mu ♏ Scorpio pa mayesi a 401,089 km kuchokera kwa Earth. Mwezi wofera watsatira uli pa May 1, 2026.
Ponena za Coordinated Lunar Time
Mu Aprilo 2024, White House idamala kuti NASA igwirizanitse Coordinated Lunar Time (LTC) ndi kumapeto kwa 2026. Chifukwa cha mphamvu ya gravitational pa Mwezi yotsika kuposa pa Earth, general relativity imaweruza kuti ma lokasi pa Mwezi amayenda ~56.02 microseconds mabwinobwino pa tsiku lililonse la Earth. Kuyambira pa miyezi ndi chaka, kuya kwakonsechi kumakwanira kumapeto akuti kutha njira kupitilizira mamita mazana angapo.
LTC idzawerengedwa ndi kuchuluka kwa ma lokasi a atomic omwe azigwiritsidwa ntchito pa Mwezi — mofanana ndi momwe UTC imawerengedwa pa Earth. Komiti ya UN yomwe ili ndi zidziwaniro za Global Navigation Satellite Systems (ICG) idapangitsa gulu lomwe lingakavomela (working group) mu 2024 kuti igwirizanitse nthawi ya mwezi ndi kugwiranso (traceability) ndi UTC.
LTC yomwe ikuwonetsedwa pano imawerengetsa kuya kokonkozane kwa J2000.0 astronomical epoch pa nthawi ya +56.02µs/tsiku ndipo imawonjezera mu UTC yomwe ili pa nthawi iyi, kupereka lingaliro la zomwe ma lokasi pa Mwezi angawonetsedwe.
Mu Ogositi 2024, NIST idafalitsa lingaliro kuti mulhani nthawi pa mwezi lolemba momwe kuti nthawi ya mwezi ingawerengedwe kuchokera mu relativistic corrections kwa UTC. Njira ya masamu imawona kuphatikiza gravitational blueshift (ma lokasi pa Mwezi amayenda mabwinobwino chifukwa cha mphamvu yotsika) ndi zida za velocity-dependent effects, zomwe zimapeza +56.02 microseconds pa tsiku lomwe limagwiritsidwa ntchito pa malo pano.
Kulungamitsa nthawi ya mwezi ndi ntchito ya anthu ochokera m'malo osiyanasiyana. Artemis Accords, zomwe zapainisa anthu angapo kuposa makumi asanu, zimavomereza kuti pali nthenda ya mapulogalamu omwe akugwitsa ntchito limodzi pa Mwezi — ndipo kaphatikiziro komwe kumakudziwanira kwa nthawi ndilo maziko. Moon Time Now ipatsitsani malo pano, nkhalakwe ya magawo a mwezi, ndi API yomasuka kuti iyamba ochita lipunguzo, ophangani masankhu, ndi anthu omwe ali ndi chidwi kuti azindikire kuchita nthawi ya mwezi kuvuta.
Mafunso Omwe Amafunsidwa Nthawi Zambiri
Ndi nthawi yiti pa Mwezi?
Mwezi palibe standard timezone. NASA imodzunkunira kugwiritsira ntchito Coordinated Lunar Time (LTC) yokonjezera kuya kwa relativistic (+56.02 microseconds pa tsiku) kwa UTC. moontimenow.com ikuwonetsa simulation yotsatira ya zomwe ma lokasi omwe ali pa Mwezi angawonetsedwe.
Chifukwa chiyani nthawi imayenda mabwinobwino pa Mwezi?
Chifukwa cha mphamvu ya gravitational pa Mwezi yotsika kuposa pa Earth, general relativity imaweruza kuti ma lokasi pa Mwezi amayenda ~56.02 microseconds mabwinobwino pa tsiku lililonse la Earth. Izi zimatchedwa gravitational time dilation.
Coordinated Lunar Time (LTC) ndi chiyani?
LTC ndi standard ya kunthawiza yomwe yadundulidwa ndi White House mu Aprilo 2024 kuti NASA igwire ma nkhawa ndi kumapeto kwa 2026. Idzawerengedwa ndi kuchuluka kwa ma lokasi a atomic omwe azigwiritsidwa ntchito pa Mwezi, mofanana nomwe UTC imawerengedwa pa Earth. Phunzirani zambiri ponena za LTC.
Mwezi walosera kupi kuposa Earth?
Kuyambira kwa J2000.0 epoch (Chezamtanda 1, 2000), Mwezi walosera kupi kuposa kwa Earth ma lokasi, kumakwanira kupitilizo ndi nthawi ya +56.02 microseconds pa tsiku chifukwa cha gravitational time dilation.
LTC idzawerengedwa liti kuti izikhale yeniyeni?
White House idamala kuti NASA akhale ndi framework ya LTC yomwe ndi bwino ndi kumapeto kwa 2026, kuti iyambire Artemis III crewed landing. NIST idafalitsa technical framework mu Ogositi 2024, ndipo ICG ya UN ikukonchedwa kuti ione zomwe zimakutsata pa nthawi yomwe izi zidzakhala.
Moon time yomwe ili pa malo pano imawerengedwa motani?
Timalemba nthawi ya relativistic drift ya +56.02 microseconds pa tsiku kwa UTC, kumakwanira kuchokera kwa J2000.0 epoch (Chezamtanda 1, 2000 pa 12:00 UTC). Magawo a mwezi amagwiritsira ntchito algorithm ya Meeus ndi nthawi 25 zomwe zikumveramukanso, kulondeza kosiyanasiyana pakupitiliza maminiti awiri.
Gawo la mwezi lomwe lili lero ndi liiti?
Gawo la mwezi lomwe lili lero likuwonetsedwa m'mwambamwa mwa malo pano ndipo likugwirizanitsidwa pa sekondi iliyonse. Kwa nkhale yokwanira ya mwezi, tiyeni Moon Phase Calendar.
Chifukwa chiyani timafuna nthawi yosiyanasiyana kwa Mwezi?
Ngati palibe standard ya nthawi ya Mwezi, systems ya navigation pa Mwezi angachite zolakwa za malo mamita mazana angapo pa tsiku. Coordinated Lunar Time imakunsemesa kuti spacecraft, rovers, ndi lunar bases zikukhala ndi gwirizano pa lero lakuti. Phunzirani zambiri.
Njira yotsatira ya lunar time yomwe ili pano ili ndi kulondeza kotani?
Nthawi ya drift ya 56.02 µs/tsiku inachokera mu kuwerengeka kwa relativistic kwa NASA ndi NIST. Clock simulation yathu ili ndi kulondeza kwa millisecond kwa component ya drift. Nthawi ya moon phase ili ndi kulondeza mpaka maminiti awiri kuposa kwa zomwe zinalembedwa ndi USNO.
Ndi mitha yogwirira kugwiritsira ntchito Moon Time API?
Inde! JSON API yathu yomasuka imabweza LTC yomwe ndi simulation, kuya kokonkozane, kuya kwa lero, ndi moon phase data. Palibe zowonjera.
Phunzirani Ponena za Lunar Time
Coordinated Lunar Time (LTC) Ndi Chiyani?
Malonzi omwe akuphunzitsa kwa NASA imodzunkunira Coordinated Lunar Time — standard yatsopano ya nthawi pa Mwezi ndi chifukwa ichi chimapangitsa pang'ono pa space exploration.
Chifukwa Chiyani Nthawi Imayenda Mabwinobwino pa Mwezi
Einstein's general relativity imaweruza kuti mphamvu yotsika imanena kuti ma lokasi amayenda mabwinobwino. Umu chifukwa chimapangitsa kuti Mwezi ayenda 56 microseconds pa tsiku — ndi chifukwa ichi chimapangitsa kwa kunthawiza kwa Mwezi.
Momwe Lunar Time Iyezeledwa
Technical details yomwe ili kumbuyo kwa lunar time — kuchokera kwa J2000 epoch reference mpaka Meeus algorithm yomwe iyezeledwa magawo a mwezi kumakutsata maminiti awiri kulondeza.
Magawo a Mwezi Kufotokozedwa: Guide Yokwanira
Zonse zomwe mufuna kudziwa ponena za magawo 8 a Mwezi — kuchokera kwa new moon mpaka full moon ndi kubwerera. Sayansi ya synodic cycle yomwe ndi 29.53-tsiku kufotokozedwa.
