Time moves faster on Mars than on Earth: Scientists calculate the exact difference
Scientists have calculated exactly how much faster clocks tick on Mars and what it means for future missions there.
Scientists have revealed that time moves faster on Mars than on Earth, with a clock on Mars ticking 477 microseconds faster per day compared to a clock on Earth. The study, conducted by physicists at the US National Institute of Standards and Technology, examined the difference in timekeeping between Mars, Earth, and the Moon. Factors such as Mars' weaker surface gravity and its longer 687-day year contributed to the complexity of the calculations.
Mars' day, called a sol, lasts about 24 hours, 39 minutes and 35 seconds, which is roughly 39.5 minutes longer than an Earth day. This discrepancy in timekeeping will pose challenges for future missions and human habitation on Mars, as it will require synchronization of spacecraft systems and human circadian rhythms.
