How to Survive in Orbit: The Physics of Life Support - Kevin Fong's 2015 Christmas Lectures 2/3

In the second his CHRISTMAS LECTURES, space doctor, Kevin Fong explores 'Life in orbit' on board the International Space Station. As British astronaut Tim Peake settles in to his new home on the Station he sends special reports about what it takes to live and work in space. 400 km above the Earth, hurtling at a speed of 17,500 mph, astronauts' bones and muscles waste away, the oxygen they breathe is artificially made, they face constant threats from micrometeorites, radiation and extreme temperatures. If a medical emergency strikes, Tim Peake is a very long way from home! In its 15 year lifetime, the International Space Station has never had a major accident. With a British astronaut in orbit, gravity defying experiments and guest astronauts in the lecture theatre Dr Kevin Fong shows us how to survive 'Life in orbit.' About the 2015 CHRISTMAS LECTURES In December 2015, Tim Peake became the first Briton in space for more than 20 years and a new member of the European Astronaut Corps. As Tim adjusts to life onboard the International Space Station (ISS), Kevin Fong's CHRISTMAS LECTURES take us on a journey from planet Earth into Low Earth Orbit and beyond. This is the story of human survival against all the odds; the story of how science, medicine and engineering come together to help answer our biggest questions about Life, the Earth, the Universe and our place in it. From artificial gravity and greenhouses in space to plasma drives and zero-G surgical suits, these lectures reveal how what once was the stuff of science fiction is fast becoming today’s science fact. Throughout the three-part series, Kevin is be accompanied by special guest appearances from ISS astronauts who will reveal what daily life is like 400 kilometres above the Earth. We will explore the technology and techniques that help them stay safe and healthy, and discover scientific experiments taking place on the ISS which are helping to stretch the limits of our understanding of human physiology and survival in a way that no experiment back on Earth could. --- Join this channel to get access to perks: https://www.youtube.com/channel/UCYeF244yNGuFefuFKqxIAXw/join Subscribe for regular science videos: http://bit.ly/RiSubscRibe --- Chapters: 00:00 The 17,500mph Problem: Life in a Falling Laboratory 🛰️ 05:30 Newton’s Secret: Why Astronauts Don't Actually Float 🌍 12:50 The "Vomit Comet": Mastering the Physics of Freefall ✈️ 18:15 The Chemistry of Survival: Turning Water into Oxygen 🧪 32:45 Why Candles Melt Upwards: Convection in Zero-G 🕯️ 39:10 Bones to Dust: The Lethal Cost of Unloading the Skeleton 🦴 50:15 Chicken Legs & Puffy Face: The Body's Fluid Mystery 🩸 58:20 Engineering a $50,000,000 Shield: The Orlan Space Suit 🧥 01:05:10 Kinetic Ballistics: Why Speed is Deadlier than Mass 🥕💥 01:15:30 Surgery in a Vacuum: The Reality of Space Medicine 🚑 01:21:40 Adiabatic Heating: Why Re-entry Air Turns to Fire 🔥 01:27:10 Touching 1,100°C: Defying the Laws of Thermodynamics 🧱👐 --- The Ri is on Twitter: http://twitter.com/ri_science and Facebook: http://www.facebook.com/royalinstitution and TikTok: https://www.tiktok.com/@ri_science Listen to the Ri podcast: https://podcasters.spotify.com/pod/show/ri-science-podcast Donate to the RI and help us bring you more lectures: https://www.rigb.org/support-us/donate-ri Our editorial policy: https://www.rigb.org/editing-ri-talks-and-moderating-comments Subscribe for the latest science videos: http://bit.ly/RiNewsletter Product links on this page may be affiliate links which means it won't cost you any extra but we may earn a small commission if you decide to purchase through the link. #SpaceSurvival, #LifeSupportSystems, #PhysicsOfOrbit, #KevinFongLectures, #ChristmasLecture2015
