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 ...
Astronauts age more slowly than people on Earth. The difference isn't noticeable though — after spending six months on the ISS, astronauts age about 0.005 seconds less than the rest of us.
It is still unknown whether bone recovers completely. Unlike people with osteoporosis, astronauts eventually regain their bone density. [citation needed] After a 3–4 month trip into space, it takes about 2–3 years to regain lost bone density. [citation needed] New techniques are being developed to help astronauts recover faster. Research on ...

New science hints that young bodies may be aging faster than ever, and it comes at a time when cancer rates are climbing in young people. We explore the link.
The first space rendezvous was accomplished by Gemini 6A and Gemini 7 in 1965.. Records and firsts in spaceflight are broadly divided into crewed and uncrewed categories. Records involving animal spaceflight have also been noted in earlier experimental flights, typically to establish the feasibility of sending humans to outer space.
