Atomic clocks are ultra-precise timekeeping devices that use atomic vibrations to measure time accurately. NASA may use atomic clocks on the moon to ensure precise timekeeping for missions and communication. In the moon's low-gravity environment, where time moves slightly faster than on Earth due to gravitational effects, atomic clocks provide a reliable reference for coordinating with Earth.

Resolves Yes if NASA uses atomic clocks as part of their initial timekeeping method.
