Human crews headed for Mars are still looking at journeys that last most of a year, long enough for radiation, boredom and mechanical risk to pile up. Nuclear propulsion promises to compress that ...

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 ...

Clocks on Mars tick faster by about 477 microseconds each Earth day, a new study suggests. This difference is significantly ...

Scientists find that time on Mars runs 477 microseconds faster than on Earth, a discovery that could enhance deep-space communication and future exploration ...

"A three-body problem is extremely complicated. Now we're dealing with four: the sun, Earth, the moon and Mars. The heavy lifting was more challenging than I initially thought." When you purchase ...

On Earth, knowing the time feels simple. Your phone pings the same second as a GPS satellite and an atomic clock in a lab. Everything is wired together so well that you rarely think about the ...

Clocks tick faster on Mars than they do on Earth, in part because Mars experiences less gravitational pull from the Sun. Now scientists have calculated just how much faster -- 477 microseconds, on ...
