Do Astronauts Age Slower?

So depending on our position and speed, time can appear to move faster or slower to us relative to others in a different part of space-time. And for astronauts on the International Space Station, that means they get to age just a tiny bit slower than people on Earth. That's because of time-dilation effects.

It's long been known that exposure to radiation damages DNA, but a new study has found an additional risk for astronauts: DNA replication is more prone to errors in microgravity.
