There is probably an unbelievably long list of the challenges that human astronauts would face in the event of a manned mission to Mars. Dealing with time dilation is definitely on the list.

A new study in Physical Review Letters has used atomic clocks to study relativistic effects in interacting quantum systems.

Astronauts age slightly slower in space due to microgravity and time dilation, as observed with Sunita Williams and Barry ...

Rotating black holes are the most powerful phenomenon in the known universe. Their powerful gravity radically alters the curvature of spacetime around them, leading to relativistic effects like time ...

He called the slowing of time due to motion time dilation. Imagine you're standing on Earth holding a clock. Your friend is in a rocket zooming past you at nearly 186,000 miles per second.
