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 ...

Potential solvents identified for building on moon and Mars

Researchers have taken the first steps toward finding liquid solvents that may someday help extract critical building materials from lunar and Martian-rock dust, an important piece in making long-term space travel possible. Using machine learning and computational modeling, researchers have found about half a dozen good candidates for solvents that can extract materials on the moon and Mars usable in 3D printing. The powerful solvents, called ionic liquids, are salts that are in a liquid state.
