As lunar missions ramp up, a hidden problem is quietly becoming mission-critical: time itself breaks once you leave Earth.
Clocks on the Moon tick faster than clocks on Earth—not because of engineering errors, but because of Einstein’s relativity. The difference is tiny, about 56 microseconds per day, but that drift compounds into navigation errors, communication failures, and autonomous system disagreements that can derail entire missions.
