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 ...

Self-driving rovers explore Moroccan desert, shooting for Mars

Ever since the first successful landing on Mars in the 1970s, scientists have striven to deepen their knowledge of the red planet's surface. The first successful rover, the Sojourner, was deployed on Mars's surface in July 1997. Since then, there have been another three successful robotically operated rovers on the planet, collecting information on water, rocks, soils and minerals, and the presence of organic material.
