What if the International Space Station turned into the world’s biggest science fair? That’s Axiom Mission 4. Four crew members have ferried 60+ experiments from 31 countries to low-Earth orbit, probing everything from human biology to smart electronics. Here’s the quick-look guide you need before hitting play: 🇮🇳 India: 8 Experiments in One “Cosmic Backpack” Zero-G Touchscreens – Can astronauts still swipe accurately while floating? Edible Microalgae – Testing space-grown salad greens. Cyanobacteria – Using bacteria to recycle air and maybe make food on Mars. Muscle-Loss Countermeasures – Dietary supplements vs. microgravity atrophy. Seed-to-Seed Gardens – Tracking multiple plant generations in orbit. Tardigrade Stress Tests – How do the toughest life-forms handle real micro-g? 7–8. Student STEM Demos – Two hands-on experiments built for classroom inspiration. Global Village Highlights Spain: Brain-wave monitoring to decode stress and sleep in space. Turkey: First national astronaut running space-health and student payloads. Italy: Visual-motor tests—think catching a ball when “up” disappears. Ukraine: Blood-analysis study on immunity shifts. Norway: Autonomous diagnostic tech for doctor-free deep-space care. Hungary: Matchbox-sized sensors forecasting radiation “weather.” Mexico & Colombia: Classroom biology modules on growth and genetics. Saudi Arabia: Bone-density and spine-curvature tracking for long missions. Switzerland: Wearable vitals monitors fine-tuned for microgravity. Plus art, novel materials, and next-gen electronics—all hitching a ride. Who’s Behind the Payloads? University teams turning class projects into orbital research. Start-ups trial-running devices for future Moon- and Mars-bound crews. Medical innovators watching cells misbehave so new treatments emerge. Why It Matters Space-grown crops, AI-driven medical checks, global student access—each experiment is a pixel in the picture of democratized space.
