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 aboard the ISS, on the other hand, are much farther from Earth's center of gravity than the rest of us — about 260 miles farther. So, in that case, astronauts actually age slower .
White's astronaut interviews confirmed the importance of the difference between intellectual knowledge versus experience, of perceiving the "striking thinness of the atmosphere", of thinking of ourselves interconnected and part of the Earth as an organic system, and that we as different people "are all in this together".

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 ]
The trio revealed some anecdotes about the trials of readjusting to life on Earth after spending more than 230 days in space. The astronauts remained tight-lipped about the nature of the medical ...
Einstein discovered that time is relative while Isaac Newton had thought of time as absolute. Time runs faster for astronauts than people on Earth; people on Earth experience time more slowly because they are closer to the gravitational field of the massive Earth. Studies have shown that for many people time can feel like it goes by faster as ...
On Wednesday, Aug. 7, the agency held a news conference giving an update on the two astronauts who have been in outer space for 63 days — approximately seven weeks longer than expected ...
Studies have found that Mars, on the other hand, has vast reserves of frozen water, all of the basic elements, and more closely mimics both gravitational (roughly 1 ⁄ 3 of Earth's while the moon is 1 ⁄ 6) and illumination conditions on Earth. "It is easier to subsist, to provide the support needed for people there than on the Moon."
