In the future, industrialisation of space and exploration of inner and outer planets will require humans to endure longer and longer periods in space. The majority of current data comes from missions of short duration and so some of the long-term physiological effects of living in space are still unknown.
The human body was not built for spaceflight, with its microgravity conditions, exposure to high-energy radiation and other issues. As a result, trekking beyond the Earth's confines causes many ...
Illnesses and injuries during space missions are a range of medical conditions and injuries that may occur during space flights. Some of these medical conditions occur due to the changes withstood by the human body during space flight itself , while others are injuries that could have occurred on Earth's surface.
Sleeping in space is part of space medicine and mission planning, with impacts on the health, capabilities and morale of astronauts. Human spaceflight often requires astronaut crews to endure long periods without rest. Studies have shown that lack of sleep can cause fatigue that leads to errors while performing critical tasks.
[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]
University researchers have teamed with astronauts to test an experimental drug, rebecsinib, they say appears to act as a "kill switch" for cancer—at least in space, where aging is accelerated.
Space exploration also gives scientists the ability to perform experiments in other settings and expand humanity's knowledge. [67] Another claim is that space exploration is a necessity to humankind and that staying on Earth will eventually lead to extinction. Some of the reasons are lack of natural resources, comets, nuclear war, and worldwide ...
“A space elevator becomes a bridge to the entire solar system,” says Stephen Cohen, who teaches physics at Vanier College in Montreal and has conducted extensive research on the mechanics of ...
