dependence of risk on dose-rates in space related to the biology of DNA repair, cell regulation and tissue responses; predicting solar particle events (SPEs) extrapolation from experimental data to humans and between human populations; individual radiation sensitivity factors (genetic, epigenetic, dietary or "healthy worker" effects)
That system failed in space during the final phase of Ariane 6's otherwise successful debut launch in July, adding to the global rocket industry's long list of pressurization challenges ...
The space agency said late Wednesday in a post on X, formerly known as Twitter, that two additional helium leaks had been detected on the vehicle. One helium leak had been discovered prior to ...
The launch delay – the second since the Polaris Dawn crew arrived last week in Florida – was necessary to give ground crews time to take “a closer look at a ground-side helium leak” on a ...

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.
The capsule, carrying four citizens, was expected to lift off early Tuesday from NASA’s Kennedy Space Center in Florida, but a helium leak pushed the launch until no earlier than Wednesday.
[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]
