The most precise timekeepers ever made, atomic clocks, might one day help robotic and crewed missions on Mars stay in sync ...

Time on Mars does not match time on Earth, and the difference is no longer a thought experiment. Precision calculations now show that clocks on the red planet tick measurably faster, confirming a ...

Mars clocks tick 477 microseconds faster per Earth day, complicating future missions and interplanetary timekeeping.

Time moves differently on Mars — not in the Tibetan philosophy sense of the word, but in a measurable, physics-will-ruin-your-mission kind of way that's giving NASA engineers a real headache. As the ...
