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 ...

Study shows how icy outer solar system satellites may have formed

Using sophisticated computer simulations and observations, a team led by researchers from the Earth-Life Science Institute (ELSI) at Tokyo Institute of Technology has shown how the so-called trans-Neptunian objects (or TNOs) may have formed. TNOs, which include the dwarf planet Pluto, are a group of icy and rocky small bodies—smaller than planets, but larger than comets—that orbit the solar system beyond the planet Neptune. TNOs likely formed at the same time as the solar system, and understanding their origin could provide important clues as to how the entire solar system originated.
