From the crackle of a Geiger counter to the quiet pulse of an ultrasound, this episode explores how we detect the invisible. I dive into the science of radiation — cosmic, ionizing, non-ionizing — and how it’s measured in space. We’ll talk about Geiger counters aboard spacecraft, sonar and why it doesn’t work in space, and how ultrasound waves are used not just in medicine, but even in space operations.I also share the chilling story of the Demon Core, a real-life radiation accident during the Manhattan Project that changed the way we handle nuclear material forever.And then… I bring it all home. In a personal twist, I reveal something new on the horizon for me and my family — using the very same invisible waves we’ve been talking about.This one’s about radiation, waves, and signals in the silence — both out there in the stars, and right here on Earth.🔬 Topics Covered:Types of radiation: ionizing vs non-ionizingGeiger counters in space explorationWhy sonar doesn’t work in spaceHow ultrasound helps us detect lifeThe true story of the Demon CoreA surprise at the end of the Video!🛰️ Stay curious, and keep looking up.#RedMarsLabs #SpaceTechnology #Radiation #Ultrasound #DemonCore #AstroJake #SpacePodcast #NewBabyReveal #SpaceScience #InvisibleWaves
