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 ...

NASA has Decided to Start Building the Lunar Gateway Using the Falcon Heavy

NASA recently announced that they've decided to launch the Lunar Gateway's core modules on SpaceX Falcon Heavy rockets. According to the agency, the Power and Propulsion Element (PPE) and the Habitation and Logistics Outpost (HALO) will be lofted into lunar space by the superheavy rocket as early as 2024. This is a big departure from NASA's original plans to launch components on the Space Launch System, which is still under construction and has undergone several delays.
