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 ...

Naturally occurring 'batteries' fueled organic carbon synthesis on Mars

Mars' organic carbon may have originated from a series of electrochemical reactions between briny liquids and volcanic minerals, according to analyses of three Martian meteorites. The discovery that natural systems can form a small corrosion-powered battery that drives electrochemical reactions between minerals and surrounding liquid has major implications for astrobiology. A similar process could occur anywhere that igneous rocks are surrounded by brines, including the subsurface oceans of Jupiter's moon Europa and Saturn's moon Enceladus.
