As U.S. clocks shift forward this weekend, many earthlings will find themselves momentarily confused about what time it is. But scientists say a far larger temporal problem is looming on the horizon: ...

Time zones are important. They make it easy to know that when it's 3 p.m. in New York, it's noon in Los Angeles. But what time is it on the moon? Back in April, the Biden-Harris administration asked ...

Time runs faster on Mars (477 microseconds/day) due to relativity. Discover how this fundamental physics challenge requires dynamic correction to prevent massive GPS errors and secure future deep ...

Astronauts, set your watches. Time on the surface of the moon has been calculated to tick at a rate of 57 millionths of a second a day faster than it does on Earth, a difference that could be crucial ...

The U.S. government calculates the country's official time using more than a dozen atomic clocks at a federal facility northwest of Denver. But when a destructive windstorm knocked out power to the ...

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 ...

Research conducted by two physicists from the National Institute of Standards and Technology (NIST) in the US reveals that clocks on Mars tick 477-millionths of a second (or 477 microseconds) faster ...
