Check out this study by Nils Averesch that asks whether living fungal biomass could contribute to radiation protection beyond Earth orbit! Here is my new cover art inspired by the experiment!

Outer Space is so dangerous. One day the station's iguana Iggy got hit my a random cosmic ray. All 1043 crew members were eaten within hours.

3️⃣ การใช้ชีวิตที่ยากลำบาก

⤷ ภาวะไร้น้ำหนักที่ดูสนุกในคลิป จริง ๆ เป็นโจทย์โหดของร่างกาย
⤷ กระดูกจะค่อย ๆ สูญเสียความหนาแน่น กล้ามเนื้อจะอ่อนแรงลง ถ้าไม่มีการออกกำลังกายและมาตรการรับมือที่เข้มพอ
⤷ นี่ยังไม่รวมรังสีอวกาศ, การอยู่ในพื้นที่ปิด, การต้องอยู่กับคนเดิม ๆ นานเป็นเดือน หรืออาจเป็นแรมปี

Review of Solar Energetic Particle Prediction Models
Solar Energetic Particle (SEP) events are interesting from a scientific perspective as they are the product of a broad set of physical processes from the corona out through the extent of the heliosphere, and provide insight into processes of particle acceleration and transport th

Deployed Electromagnetic Radiation Deflector Shield Creating a Zone of Minimum Radiation and Magnetic/Plasma Effects for Spacecraft - NASA Technical Reports Server (NTRS)
Spaceflight outside of the Earth's protective magnetic field is dangerous from a cosmic radiation perspective. Inside Earth's magnetic field, where the manned International Space Station (ISS) orbits, the radiation encountered is minimal and almost all is deflected by our planet's magnetic fields. However, outside that protective shield, the Sun's solar wind (high energy radiation, solar energetic particles or SEPs) consisting of protons, electrons, alpha particles and plasmas continuously bombards the spacecraft for the months or years of spaceflight. On occasion the Sun produces a CME (Coronal Mass Ejection) that vastly increases the energy and volume of this radiation. These particles damage human DNA as well as living tissue and can destroy sensitive electronics. The Deployed Electromagnetic Radiation Deflector Shield (DERDS) provides a magnetic field that will deflect SEPs and CMEs and other harmful solar and cosmic rays away from a manned spacecraft, robotic spacecraft, or manned extra-planetary base stations using an electromagnet that is deployed between the spacecraft/station and the source of radiation and creates a magnetosphere or zone of minimal radiation in which the spacecraft or base station would reside.

But the real bullseye was orbit. The blast created an artificial radiation belt, far more intense than any natural one. Within months, it fried electronics on Telstar, Ariel 1, and TRAAC satellites. Civilian communications stammered; the Space Age hit an invisible wall. (4/6) #spaceradiation #tel...

"Did you know that space radiation on the Orion spacecraft is similar to being in a nuclear reactor for 30 DAYS STRAIGHT? Imagine being exposed to lethal doses of radiation equivalent to 30 straight years in a Chernobyl nuclear power plant. Mind blown #SpaceRadiation #OrionSpacecraft"

"Did you know that astronauts on the Orion spacecraft will receive a daily dose of space radiation equivalent to 100 times the annual limit for a commercial airline pilot? Think of it like flying 100 times a year instead of 1 - the cumulative effect is staggering #SpaceRadiation #Orion"

"Did you know that to protect Astronauts from Space Radiation, NASA had to build a 'space shield' around the Orion spacecraft that's only 1/10th the thickness of a human hair? Think of it like wrapping a tiny thread around a skyscraper!" #SpaceRadiation #OrionMission

"Using active shields that deflect charged particles just like the Earth’s magnetic field does—was first proposed in the 1960s. Today, we’re finally close to making it work."

"Did you know that space radiation on the Orion spacecraft can be 7,000 times stronger than the lethal dose of a typical X-ray at a mammogram? That's like being exposed to 7,000 times the radiation of a chest CT scan, yet still safe to fly to the Moon #SpaceRadiation #Orion"
