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 ...

Single cloud in Mars

Every Spring a Single Cloud Forms at one of Mars' Tallest Mountains and Only Lasts for a few Hours

Since Mars has the tallest mountains in the Solar System, it can have unique weather conditions. Every spring in the northern hemisphere on Mars, a huge cloud forms at the top of Arsia Mons and stretches back for 1,800 kilometers. It only lasts for a few hours in the morning before dissipating, and it's been a mystery to planetary scientists. Why does it form? Why does it fade? Why does it only happen with this mountain and not the larger Olympus Mons?
