Put another way, the space ship sees the image change from a red-shift (slower aging of the image) to a blue-shift (faster aging of the image) at the midpoint of its trip (at the turnaround, 3 years after departure); the Earth sees the image of the ship change from red-shift to blue shift after 9 years (almost at the end of the period that the ...
Time can appear to move faster or slower to us relative to others in a different part of space-time. That means astronauts on the International Space Station age slower than people on Earth.
After 6 months on the International Space Station (ISS), orbiting Earth at a speed of about 7,700 m/s, an astronaut would have aged about 0.005 seconds less than he would have on Earth. [11] The cosmonauts Sergei Krikalev and Sergey Avdeev both experienced time dilation of about 20 milliseconds compared to time that passed on Earth.
It's a different kind of space age.
Hayley Arceneaux (born December 4, 1991) is an American physician assistant and commercial astronaut.She joined billionaire Jared Isaacman on SpaceX's first private spaceflight Inspiration4, which launched on September 16, 2021, 00:02:56 UTC, and successfully water-landed local-time on Saturday, September 18.

Autophagy declines with age, contributing to cellular aging and associated health issues such as decreased immune function and chronic inflammation. By enhancing autophagy, it may be possible to mitigate these effects and improve overall healthspan. Aims to Enhance Healthspan on Earth and Improve Astronaut Health in Space
The iconic puffy white suits that astronauts have donned for decades as they step outside the International Space Station are rapidly aging — but NASA is now without concrete plans to replace them.
The studies support earlier work that found such journeys could significantly damage the brains of astronauts, and age them prematurely. [18] In March 2019, NASA reported that latent viruses in humans may be activated during space missions, adding possibly more risk to astronauts in future deep-space missions. [19]
