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.
Water cohesion plays a bigger role in microgravity than on Earth. In space, astronauts lose fluid volume—including up to 22% of their blood volume. [81] When the astronauts return to Earth, low blood volume can cause orthostatic intolerance or dizziness when standing. [82]
If the samples age more quickly in space, scientists will learn more about the process far faster than they would if studying samples on Earth. It is hoped that will lead to new treatments for age ...
For a long time, Avdeyev held the record for time dilation experienced by a human being. [1] [2] [3] In his 747 days aboard Mir, cumulative across three missions, he went approximately 27,360 km/h and thus aged roughly 0.02 seconds (20 milliseconds) slower from an Earthbound person's perspective, [4] which is considerably more than any other human being, except Sergei Krikalev.

For two years, NASA trains its astronauts, including have them work underwater and learn desert survival skills, to get them ready for space travel. Photos and videos show why only 360 people have ...
Experienced aviators and space travelers can suffer from space sickness. Garn began piloting at the age of 16 [15] and piloted a variety of military aircraft for 17,000 hours—more than any NASA astronaut—before STS-51-D. Charles D. Walker became ill on the same flight despite having flown on the shuttle before.
The astronauts aboard the Boeing Starliner could remain in space for several months – but many wonder if they have enough food and water to survive that long.. During a recent interview with the ...
