Upon return to Earth, he noted persistence of the vision changes he observed in space. He never experienced losses in subjective best-corrected acuity, color vision or stereopsis. This case is interesting because the astronaut did not have disc edema or choroidal folds, but was documented to have nerve fiber layer (NFL) thickening, globe ...
[a] NASA survey of 300 male and female astronauts, about 23 percent of short-flight and 49 percent of long-flight astronauts said they had experienced problems with both near and distance vision during their missions. Again, for some people vision problems persisted for years afterward. —
Astronauts who had recently returned from space missions to the Hubble Space Telescope, the International Space Station and Mir Space Station reported seeing the LF under different conditions. In order of decreasing frequency of reporting in a survey, they saw the LF in the dark, in dim light, in bright light and one reported that he saw them ...
Vision is the dominant sense for orientation, but the vestibular system, proprioceptive system and auditory system also play a role. [ citation needed ] Spatial orientation (the inverse being spatial disorientation, aka spatial-D ) is the ability to maintain body orientation and posture in relation to the surrounding environment (physical space ...
The brief mix-up highlights the sometimes difficult pursuit of tracking deep-space objects. Astronomers briefly thought Elon Musk’s car was an asteroid. Here’s why that points to a broader problem
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 ]
A record stay in earth’s orbit and a fine to Dish Network might have space debris in common. Space junk is causing problems — and experts think it’s just the start. Why it matters
Records of medical problems that were encountered by astronauts during space flights; Information on medical conditions that occurred during expeditions on Earth in extreme environments (submarine, alpine, Arctic and Antarctic expeditions, expeditions to other remote ground-based locations, etc.) or NASA's Extreme Environment Mission Operations
