@buddhism066: In space, our greatest enemy isn't just the vast distances — it's radiation. There are three main types of radiation: - **Alpha (α)**: These are heavy, charged particles that cannot penetrate the skin but can cause significant damage if inhaled or ingested. - **Beta (β)**: These are fast electrons or positrons with moderate penetration ability; they can be stopped by thin metals such as aluminum. - **Gamma (γ)**: These are high-energy photons that have no mass or charge. Gamma rays can penetrate materials like concrete and steel, leading to deep tissue and DNA damage. To protect astronauts — and eventually civilians — NASA is working on developing radiation shields for space habitats. Proposed solutions include thick walls made of lunar regolith, hydrogen-rich plastics, layers of water, and even magnetic fields to replicate Earth's natural protective shield. #foryoupage #foryou #NASA #SpaceHomes #SpaceRadiation #FutureLife #AstroFacts #AstronomyReels #ScienceReels #SpaceExploration #MarsMission #STEM
