Dunia juma kɔ Artemis program kɔ, challenge kelen ye kɔ: juma kanji ye ala? April 2, 2024, White House OSTP ka NASA ka jɛ Coordinated Lunar Time, o LTC, 2026 kɔ.
Juma Kɔ Waati Kɔnɔ Kɛnɛ
Dunia, aw ka UTC gɛ, 400+ atomic clocks jama. GPS satellites, financial systems, power grids, ak internet fɔ UTC ka gɛ.
Juma problem ye. Juma baliya gara kaban ka tuma dunia kɔnɔ, juma waati 56.02 microseconds juma kɔ kaban ye. A gravity field less — general relativity tuma — juma clock faster ye.
Microsecondi 56 juma ye negligible. Kɔ navigation systems, 16 mɛta juma kɔ error ye. Juma kelen kelen, 500 mɛta error ye — landing ak rover navigation unreliable ye.
LTC Ka Gɛ Kɛnɛ
Coordinated Lunar Time UTC principles kɔ ka gɛ, juma environment kɔ adapted. A plan atomic clocks juma surface ak lunar orbit kɔ ye ka gɛ. LTC atomic clocks weighted average ye UTC kɛnɛ dunia la.
LTC well-defined relationship UTC kɔ gɛ, waati Earth ak Moon kɔ seamlessly convert kɛ. Key difference relativistic offset — cumulative drift ka lunar clocks faster ye.
NIST August 2024 kɔ technical framework juma waati kɔnɔ mathematical model jɛ.
International Effort
Juma timekeeping NASA project jɔ. UN ICG 2024 kɔ dedicated working group ye juma timing standardize kɛ. Artemis Accords 50+ dugu juma interoperable systems kɛ.
ESA (European Space Agency) Moonlight initiative juma timekeeping jɛ, juma kɔ communication ak navigation services kɛ.
LTC Future Kɛnɛ
Standardized juma time landers ak rovers precision navigation kɛ, Earth ak Moon communication scheduling kɛ, missions coordination kɛ, ak juma ak Mars kɔ timekeeping foundation kɛ.
moontimenow.com ka simulated Coordinated Lunar Time +56.02 microseconds juma drift rate kɔ J2000.0 epoch kɔnɔ ka gɛ, LTC clock kɛnɛ ye.
