Geophysical Research Letters 📆 02 August 2023 On 📆 28 October 2021, #solar ☀️ eruptions were observed by #spacecraft 🛰️ around #Earth, #Moon, and #Mars, which caused #solar energetic particle ☢️ ground level enhancement (#GLE) on the surface of three #planetary 🪐 bodies. #SEP events can induce much higher (∼100 times) #radiation ☢️ doses on the Moon 🌙 than on Mars 🔴 https://agupubs.onlinelibrary.wiley.com/doi/full/10.1029/2023GL103069

Reaching #orbit means accelerating up to around 28,000kph (22 times the speed of sound). A five-gram #bolt 🔩 hitting at #OrbitalSpeed packs as much #energy 💥 as a 200kg weight dropped from the top of an 18-storey building. The typical #radiation ☢️ dose from one day in #space is equivalent to what you’d receive over an entire year back on #Earth https://www.sciencefocus.com/space/space-travel-exploration

📆 January 2, 2020 Active #astronaut 👨‍🚀 surveillance and experimental models are critical to the development of prevention and management strategies for venous #thromboembolism 🩸 in #weightlessness, especially with future plans for prolonged #SpaceTravel to the #Moon 🌙 and #Mars 🔴 https://www.nejm.org/doi/full/10.1056/NEJMc1905875

Reuters - Study reveals how immune system of astronauts breaks down

Gene expression was at about one third the normal levels while in #space, the study found. This occurred within the first few days in space, but then remained at a stable level.
Other documented effects of #SpaceTravel include #bone 🦴 and #muscle 💪 atrophy, #cardiovascular changes, issues with the balance system in the inner ear and a syndrome involving the #eyes 👁️. Cancer risk from greater #radiation exposure is another concern. https://www.reuters.com/technology/space/study-reveals-how-immune-system-astronauts-breaks-down-2023-06-22/

“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

#NYT 📆 May 5, 2023 The #northern lights have expanded farther #south. This phenomenon will peak in 📆 2025, during the phase known as #solar ☀️ maximum 📈. https://www.nytimes.com/2023/05/05/science/northern-lights.html

#SpaceWeather "The exposure of a human body to ionizing #radiation ☢️ has the same harmful effects whether the source of the radiation is a medical X-ray machine, a nuclear power plant, or radiation in #space 🌌. The degree of the harmful effect depends on the length of exposure and the radiation's energy #density." https://en.wikipedia.org/wiki/Space_weather#Humans_in_space

#ESA 📆 26/08/2022 in 📆 August 1972, a series of powerful solar 🔆 storms took place in the middle of #NASA’s #Apollo 16 and 17 #Moon missions. It is thought the #radiation dose delivered would have caused acute radiation #poisoning 🤢. For an #astronaut on a spacewalk, it could be #lethal ☠️ https://www.esa.int/Space_Safety/Space_weather/Protecting_Artemis_and_lunar_explorers_from_space_radiation
