Time is relative. The ticking of the clock, even of the most precise clocks we can make, does not exist in an absolute. It depends on the gravity you are experiencing and on your speed. Being on the ...

Clocks on Mars tick faster by about 477 microseconds each Earth day, a new study suggests. This difference is significantly more than that for our moon, posing potential challenges for future crewed ...

Thanks to Einstein’s relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the difference, showing that Mars clocks tick slightly faster—and fluctuate over the ...
