#LunarGateway : no #radiation shelter planned.

#ESA : Radiation poses a major #health #risk to people in #space. Astronauts on the #ISS receive doses roughly 120 times higher than on Earth. Away from Earth’s protective magnetic field, #astronauts 👨‍🚀 receive roughly 250 times 📈 more radiation than a person on #Earth 🌍" https://blogs.esa.int/exploration/internal-radiation-payload-approved-for-the-gateway

#NASA : "During a future #Artemis mission, if a solar ☀️ radiation squall were to occur while #astronauts are beyond #Earth’s magnetic bubble, they might tell the crew to #build a temporary shelter 📦" https://www.nasa.gov/feature/goddard/2019/how-nasa-protects-astronauts-from-space-radiation-at-moon-mars-solar-cosmic-rays

“There’re a lot of hazards we don’t know about. In #LEO, we are protected by our #magnetosphere from #SpaceRadiation. If we go outside of that, all of the sudden we have #galactic #CosmicRays ☢️ we have to deal with, we have a lot of #SolarParticles we have to deal with and we also have variable #gravity”. Even a short flight beyond #ISS altitude impacts various aspects of human physiology and #microbiome 🦠 composition. https://asm.org/Articles/2022/October/Out-of-This-World-Microbes-in-Space

📆 4 August 2023 #GammaRays ☢️ coming from the #sun ☀️ at much higher #energy levels than previously anticipated.

“The sun is more surprising than we knew. We thought we had this #star figured out, but that’s not the case” https://www.independent.co.uk/space/sun-highest-energy-gamma-rays-b2387495.html

Physical Review Letters 📆 3 August 2023 "Current #theoretical models are unable to explain the details of how #solar magnetic fields shape these interactions" https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.131.051201

📆 Oct 4, 2019 “We don’t have a clue 🙈🙉🙊 about #radiation ☢️. The way #NASA handles a lot of the radiation work has been a lot of predictions 🔮. I think that we’re grossly underestimating the effects.”

In reality, some kind of radiation shielding 🛡️ will be needed https://www.theverge.com/2019/10/4/20895056/elon-musk-starship-spacex-human-health-life-support-radiation
