Mars and Earth - Small difference & big consequences

Einstein's theory of relativity suggests that time is not a constant and can vary based on gravitational fields and speed. In a strong gravitational field, time moves slower compared to a weaker one. Since Mars has a weaker gravitational field than Earth, time actually flows slightly faster there.  This concept has implications for future space missions, as the timing of communication and operation of spacecraft will need to account for this difference in how time elapses on Mars compared to Earth. Missions may need to adjust their schedules, operations, and technology to ensure accuracy and synchronization with Earth. Basically, the moment you bring gravity and velocity into the picture, time stops behaving like the simple, universal tick‑tock we experience in everyday life. And you’re absolutely right: Mars’ weaker gravity means clocks there run a little faster than clocks on Earth. What’s fascinating is how small the difference is—and how big the consequences become ...

Planetary scientists discover evidence for a reduced atmosphere on ancient Mars

The transition from a reduced planet to an oxidized planet is referred to as the Great Oxidation Event or GOE. This transition was a central part of our planet's evolution, and fundamentally linked to the evolution of life here -- specifically to the prevalence of photosynthesis that produced oxygen. Planetary geologists have discovered that Mars underwent a great oxygenation event of its own -- billions of years ago, the red planet was not so red.
