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.
Current space research pursuits are divided into the subjects of Space Biology, which studies the effects of space on smaller organisms such as cells, Space Physiology, which is the study of the effects of space on the human body and Space Medicine, which examines the possible dangers of space on the human body.

The first tourist visit to the space station was in 2001, and opportunities for private space travel have expanded in recent years. A three-day chartered flight in 2021 gave researchers the chance to examine how quickly the body reacts and adapts to spaceflight, said Susan Bailey, a radiation expert at Colorado State University who took part in ...
Space tourists experience some of the same body changes as astronauts who spend months in orbit, according to new studies published Tuesday. Research on four space tourists is included in a series ...
[80] [81] In the first 28 U.S. Space Shuttle flights (2–11 d duration), serum insulin levels (n = 129) were elevated by 55% on landing day compared to before flight. [82] Russian space life science investigators reported two-fold or greater increases in insulin levels in three cosmonauts within 1 day after they returned from a 237-d flight. [83]
In January 2023, The Washington Post reported an interactive feature on the known effects of space travel to the human body, and noted TRISH's work.In the article, former TRISH Chief Medical Officer Emmanuel Urquieta stated “Space is just not very hospitable to the human body,” explaining that humans evolved on Earth with abundant gravity and low radiation, whereas space is characterized ...
Space and survival is the idea that the long-term survival of the human species and technological civilization requires the building of a spacefaring civilization that utilizes the resources of outer space, [1] and that not doing this might lead to human extinction. A related observation is that the window of opportunity for doing this may be ...
