American astronaut Marsha Ivins demonstrates the effects of microgravity on her hair in space. The effects of spaceflight on the human body are complex and largely harmful over both short and long term. [1] Significant adverse effects of long-term weightlessness include muscle atrophy and deterioration of the skeleton (spaceflight osteopenia). [2]
Psychological and sociological effects of space flight are important to understanding how to successfully achieve the goals of long-duration expeditionary missions. Although robotic spacecraft have landed on Mars , plans have also been discussed for a human expedition , perhaps in the 2030s, [ 1 ] for a return mission.
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 ...
Several NASA studies have determined that the effects of space travel are harsher on women. A 2023 study found that female astronauts lose muscle at a faster rate than their male counterparts.
The major contribution of the joint U.S./Russian effort on the Mir space station relevant to the current risk topic was the first use of MRI to investigate volume changes in the skeletal muscles of astronauts and cosmonauts exposed to long-duration spaceflight. This began with the first joint mission, Mir-18, and continued until the final Mir ...
Due to the potential negative effects of astronaut exposure to cosmic rays, solar activity may play a role in future space travel. Because galactic cosmic ray fluxes within the Solar System are lower during periods of strong solar activity, interplanetary travel during solar maximum should minimize the average dose to astronauts.

People are now worried about their well-being after a doctor pointed out how “gaunt” Williams, 59, was starting to look. Health Concerns Arise After Photos Of Two Boeing Astronauts Stuck In ...
NASA accidentally broadcast a simulation of astronauts being treated for decompression sickness on the International Space Station (ISS) on Wednesday, prompting speculation of an emergency in ...
