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 ...
Starliner’s highly anticipated voyage lifted off atop an Atlas V rocket Wednesday at 10:52 a.m. ET from Cape Canaveral Space Force Station in Florida. The historic launch marked the first time ...
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.
Hypergolically-fueled rocket engines are usually simple and reliable because they need no ignition system. Although larger hypergolic engines in some launch vehicles use turbopumps, most hypergolic engines are pressure-fed. A gas, usually helium, is fed to the propellant tanks under pressure through a series of check and safety valves.
Spaceflight (or space flight) is an application of astronautics to fly objects, usually spacecraft, into or through outer space, either with or without humans on board.Most spaceflight is uncrewed and conducted mainly with spacecraft such as satellites in orbit around Earth, but also includes space probes for flights beyond Earth orbit.
The mission, known as Polaris Dawn, had been scheduled to lift off early Tuesday from NASA’s Kennedy Space Center in Florida. However, SpaceX announced on X that a helium leak delayed the launch ...
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.
