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 ...

Halfway mark for NOEMA construction

The completion of NOEMA phase 1, the first phase of the NOEMA project will be officially celebrated this Wednesday, September 19th. IRAM and its partner institutes have completed the first, decisive step towards one of the most important German-French-Spanish initiatives in astronomy: developing the most powerful and most sensitive telescope at millimetre wavelengths in the Northern hemisphere. Four years after the inauguration of the first NOEMA antenna, 10 15-meter dishes currently constitute the observatory and have provided groundbreaking scientific results.
