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 Martian year. These microsecond shifts could play a big role in future Mars navigation, communications, and even a solar-system-wide internet. It’s a small time gap with big consequences for space exploration.
The authors of the original article cited by this news outlet did not measure any time on Mars in any way. They did a theoretical calculation of the time difference with Earth based on astronomical data about Mars like mass, orbit, etc.
