On Earth, knowing the time feels simple. Your phone pings the same second as a GPS satellite and an atomic clock in a lab.

Gravity and motion make time pass faster on Mars than Earth, reshaping navigation, communication, and future crewed missions.

Measuring the time discrepancy between Earth and Mars will help make future navigation and communication systems on the Red ...

Tracking the first astronauts’ visit to Mars won’t be as simple as watching a clock or marking days off of a calendar. Thanks ...

Physicists have precisely measured how much faster time moves on Mars compared to Earth. This discovery, which factors in ...

Ask someone on Earth for the time and they can give you an exact answer, thanks to our planet's intricate timekeeping system, ...

Einstein explained that gravity affects each passing second. Clocks slow down where gravity grows stronger. Clocks speed up ...

This temporal lag is a direct consequence of Albert Einstein’s Theory of General Relativity. The rule is simple: the weaker ...

This means that, due to time dilation, you would age faster on Mars than on Earth. If you were to spend a whole 50 years on the Red Planet, you’d end up a whole 9 seconds older than if you had stayed ...

Before he got into talking about the Interplanetary Transport System, Musk explained why Mars would be the ideal target for human colonization efforts instead of the moon, for instance. While Mars is ...

Mars, long considered largely static, has revealed a dynamic interior in recent years. NASA’s InSight mission detected ...
