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 ...

SuperCam instrument integrated on NASA's Mars 2020 rover

The French/American SuperCam instrument has been delivered early June to NASA's Jet Propulsion Laboratory and has been integrated this week on NASA's Mars 2020 rover. The French space agency, CNES, together with university institutes in France, developed the multi-purpose camera to remotely analyze minerals, chemistry, sounds, and test for compounds associated with life, together with the Los Alamos National Laboratory (US). The announcement of the integration was made during the annual meeting of the European Astronomical Society (EWASS2019) in Lyon, that takes place 24-28 June.
