#Astronauts 👨‍🚀 travelling to #Mars would encounter #radiation ☢️ levels higher than humans have ever experienced, and be exposed to them for much longer.

To protect them, the #spacecraft would either have to be much bulkier, making launches expensive and difficult, or be made of more efficient #shielding 🛡️ materials. https://www.skyatnightmagazine.com/space-missions/how-will-humans-survive-the-journey-to-mars

Scientists at #Nagoya University 🇯🇵 are developing a low-cost 💴 system to measure and observe #SpaceWeather entirely from the ground using magneto-impedance sensors. Currents ⚡ generated by ionized particles flowing in the #magnetosphere tens of thousands of kilometers above Earth produce magnetic 🧲 field variations, the effect can be observed in the changes in the magnetic field on Earth 🌏 https://spectrum.ieee.org/space-weather

Despite guidelines and the past 30 years of research, there has been little progress on fully defining or mitigating the space radiation ☢️ risk to human crew. Schwadron et al. project that Galactic Cosmic Ray fluences will be substantially higher 📈 during the next solar cycles leading to increased background #radiation exposure and, subsequently, as much as a 20% decrease in the allowable safe days in space (outside of #LEO) https://www.nature.com/articles/s41526-018-0043-2

#Radiation ☢️ shielding is a mandatory element in the design of an integrated solution to mitigate the effects of radiation during long #DeepSpace voyages for human exploration. #Kevlar has radiation shielding 🛡️ performances comparable to Polyethylene, reaching a dose rate reduction of 32 ± 2% and a dose equivalent rate reduction of 55 ± 4% (for a shield of 10 g/cm2). https://www.nature.com/articles/s41598-017-01707-2

#ESA is contributing three key elements to the #Gateway: Lunar #IHab*, #LunarView and #LunarLink. Together, these provide a habitable space for astronauts 👨‍🚀, refuelling, storage and telecommunication capabilities, and windows to view space 🌌 and the Moon 🌙. https://www.esa.int/Science_Exploration/Human_and_Robotic_Exploration/Exploration/Gateway

* Habitable volume: 10 m3, Launch mass: 10 tonnes https://www.esa.int/Science_Exploration/Human_and_Robotic_Exploration/Gateway_Lunar_I-Hab

These particles travel from the Sun ☀️ to Earth at close to the speed of light, a journey of just eight minutes ⏱️. There would be little time to prepare.

A 𑐴𑐶𑐟𑐶 (hiti) is an ancient Newah urban water feature: a stepped, sunken courtyard with waterspouts and a central pool. These are fed through a remarkable network of pipes, reservoirs, and irrigation systems drawing water from mountain springs dozens of kilometres away. Every day, hundreds of people from the neighbourhood come to draw water, bathe, and exchange news. They are a unique and precious feature of Newa urban architecture through which neighbourhoods are created.
