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 ...

How a group of school students discovered the sounds of solar storms

,We are now truly living in the era of big data. And it's not just companies like Facebook and YouTube that are reaping the benefits, big data is transforming science too. In the space sciences, we have an unprecedented number of satellites and ground-based instruments that monitor Earth's space environment – routinely producing tonnes of data. But how do you process it all? While you may have heard about algorithms and artificial intelligence, there are some decidedly more human approaches too.
