Question

do the astronauts in the space station age differently than us on earth

In: 1

Answer 1

Yes…on extremely small scales. The ISS orbits Earth at a little over 7.6 kilometers per second…that’s very fast, way faster than a bullet, but not nearly enough to experience time dilation at an appreciable level. We have a formula for time dilation, and so we can determine that at that speed, if an astronaut spent a full year on the ISS (which they don’t), she would age 1/100th of a second slower than someone who sat still on Earth for one year.

In other words, there are 31,557,600 seconds in a year. An astronaut spending a year aboard the ISS would experience 31,557,599.99 seconds.
