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 ...

European-Japanese mission to investigate the smallest planet in the Solar System

The European-Japanese planetary mission BepiColombo lifted off from the European spaceport in French Guiana at 03:45 Central European Summer time on 20 October 2018 (22:45 on 19 October local time), on board an Ariane 5 launch vehicle. "Not only is the mission designed to investigate the planet Mercury, it will also deliver new insights into the Solar System," explains Walther Pelzer, Executive Board Member for the Space Administration at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR). "Once again, by rising to this immense challenge, Japan is proving to be a dependable aerospace partner for Europe." The spacecraft's cosmic journey through the inner Solar System will last approximately seven years.
