Crew living on the International Space Station (ISS) are partially protected from the space environment by Earth's magnetic field, as the magnetosphere deflects solar wind around the Earth and the ISS. Nevertheless, solar flares are powerful enough to warp and penetrate the magnetic defences, and so are still a hazard to the crew.
For instance, a NASA design study for an ambitious large space station envisioned 4 metric tons per square meter of shielding to drop radiation exposure to 2.5 mSv annually (± a factor of 2 uncertainty), less than the tens of millisieverts or more in some populated high natural background radiation areas on Earth, but the sheer mass for that ...
Since the risk of cardiovascular disease increases as people age, research on these diseases has become more important for space agencies - especially for long-term space missions. Other medical emergencies that have been observed in space include cases of urological [6] [7] and dental emergencies, [8] [9] as well as behavioural and psychiatric ...
People are now worried about their well-being after a doctor pointed out how “gaunt” Williams, 59, was starting to look. Health concerns started to grow after new photos of two NASA astronauts ...
Astronautical hygiene evaluates, and mitigates, hazards and health risks to those working in low-gravity environments. [1] The discipline of astronautical hygiene includes such topics as the use and maintenance of life support systems, the risks of the extravehicular activity, the risks of exposure to chemicals or radiation, the characterization of hazards, human factor issues, and the ...
At Mir, during a re-docking test with the Progress M-34 cargo freighter, the Progress freighter collided with the Spektr module and solar arrays of the Mir space station. This damaged the solar arrays and the collision punctured a hole in the Spektr module and the space station began depressurizing.
Asked why the Crew 9 Dragon couldn't return to Earth sooner, given that it's already docked at the station, Williams said that would leave the station with a single U.S. crew member aboard, Don ...
Russia on Wednesday vetoed a U.N. resolution sponsored by the United States and Japan calling on all nations to prevent a dangerous nuclear arms race in outer space, calling it “a dirty ...
