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.
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 ...
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 ...
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 ...
Space adaptation syndrome or space sickness is a kind of motion sickness that can occur when one's surroundings visually appear to be in motion, but without a corresponding sense of bodily motion. This incongruous condition can occur during space travel when changes in g-forces compromise one's spatial orientation . [ 5 ]
The 15-foot diameter capsule is only the sixth spacecraft that NASA astronauts have ridden in since the dawn of the Space Age, the first being the Project Mercury capsule and the most recent being ...
About 75% of all astronauts have taken medication during shuttle missions for conditions such as motion sickness, headache, sleeplessness, and back pain. Other common conditions include minor trauma, burns, dermatological and musculoskeletal injuries, respiratory illnesses and genitourinary problems.
Aging is natural. Some people age faster than others, often due to lifestyle factors. Here are signs your body may be aging early and how to prevent these changes.
