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 ...

Shadows on the Moon - a tale of ephemeral beauty, humans and hubris

Between 1969 and 1972, a new type of archaeological site was created. For the first time, human bodies and the technology needed to sustain them altered the landscape of another world. The astronauts from the six Apollo missions left a suite of space-age artefacts behind on the lunar surface. And not only that: the missions brought to the moon new kinds of shadows, cast by machines and bodies and flags and rovers, in an interplay of movement and stillness.
