"Time Dilation Effects on Mars-Bound Astronauts"

Astronauts heading to Mars will experience time dilation due to their relative speed and proximity to gravitational fields, causing a slight difference in the passage of time compared to Earth observers. While the effect is small for short space missions, it becomes more noticeable for longer stays on Mars. Gravitational time dilation means that a human living exactly 80 years on Mars would die about 12 seconds earlier than on Earth, but from their perspective, time would pass normally.
