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 ...

Space-related start-up technology companies create synergistic innovation

Researchers have developed innovative business models underlying the successful launch of space-related start-up technology companies in Costa Rica. A fascinating article describes how the company DIT (design, innovation, technology) Space identified key market sectors that could benefit from spaced-based technology and how implementation of the technology could benefit the company and create synergies leading to the development of further space technology. The article is published in New Space: The Journal of Space Entrepreneurship and Innovation.
