The sum of human experience has resulted in the accumulation of 58 solar years in space and a much better understanding of how the human body adapts. In the future, industrialisation of space and exploration of inner and outer planets will require humans to endure longer and longer periods in space.
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.
Space Shuttle Challenger breaks up during its 1986 launch resulting in the death of all seven crew members. This article lists verifiable spaceflight-related accidents and incidents resulting in human death or serious injury. These include incidents during flight or training for crewed space missions and testing, assembly, preparation, or ...
Frustrated by the constraints of Earth, a team of California scientists took tumor research to space—and may have discovered a ‘kill switch’ for cancer Erin Prater February 4, 2024 at 2:29 PM
[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]
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 ...
Astronaut Sally K. Ride became the first American woman to visit space in June 1983. Calandrelli said she was crying on the flight home from the mission because of the online reaction and texting ...
No extraterrestrial life has ever been discovered. But if extraterrestrial life exists, it may be vulnerable to interplanetary contamination by foreign microorganisms. Some extremophiles may be able to survive space travel to another planet, and foreign life could possibly be introduced by spacecraft from Earth. If possible, some believe this ...
