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 ...

Beresheet lunar landing site revealed

The main scientific instrument on board the Israeli Beresheet spacecraft, the SpaceIL Magnetometer (SILMAG), has now been successfully turned on in space and data returned to Earth. After its successful launch, Beresheet is circling Earth on its journey to the Moon. Prof. Oded Aharonson of the Weizmann Institute of Science is heading the team that is currently analyzing the SILMAG information to evaluate the health and accuracy of the instrument in space, as well as recording the magnetic signature of the spacecraft itself, which will then be subtracted from the measurements made on the Moon.
