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 ...

A virtual reality camera captures life and science aboard the space station

With only minutes until sunrise aboard the International Space Station (ISS), astronaut Nick Hague rushed to shut off the lights in the Japanese Experiment Module (JEM). Traveling 17,500 miles per hour, the space station orbits Earth 16 times in 24 hours, so every 90 minutes, the space station experiences a sunrise. For this sunrise, though, the speed of their approach was putting a time crunch on Hague. To capture this moment, timing was everything as he worked diligently to set up the perfect camera shot.
