Time on Mars runs 477 microseconds faster per day than on Earth

Although small, this time difference could have major implications for communication and navigation in future colonies on Mars.

Every day, clocks on Mars run 477 microseconds faster than those on Earth. While 477 microseconds may seem small, it adds up to big changes over the long term, with the red planet moving 1.7 seconds faster than Earth every decade, according to physicists from the US National Institute of Standards and Technology (NIST).

This is a consequence of Einstein's law of general relativity, which states that time does not move at the same speed everywhere in the universe. Photo: Shutterstock.

“Like current global positioning systems such as GPS, these systems will depend on precise clocks,” said co-author Dr. Bijunath Patla, a physicist at NIST. Photo: Tristan3D/Shutterstock.com.

According to experts, Mars is strongly influenced by the gravitational pull of other planets in the Solar System. Photo: kratosspace.com.

Because if we want to establish compatible communication and navigation systems between Earth and Mars, it is important that we unify the time. Therefore, researchers believe that Mars needs a completely new time zone. Photo: NASA.
