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 ...

Image: Tests complete for Orion

The first Orion spacecraft that will fly around the moon as part of Artemis to return humans to the lunar surface has finished its space-environment tests at NASA's Plum Brook Station in Ohio, U.S.. The vehicle—that can transport up to four astronauts—consists of the European Service Module, the Crew Module and connecting adapter and all elements have now been given the stamp of approval for spaceflight after being subjected to the vacuum, extreme temperatures and electro-magnetic interference it will encounter during its trip to the moon.
