Summary

Story summary

National Institute of Standards and Technology (NIST) researchers find Martian clocks tick 477 microseconds faster daily than Earth clocks due to gravitational time dilation.
Disparity complicates coordinating time among Earth, Moon, and Mars.
Mars has weaker gravity and a more eccentric orbit than Earth, driving timekeeping complexities.
Synchronization is feasible but not perfect, with a residual of 100 ns.
The research is crucial for future Mars missions and interplanetary navigation.
