Have you ever wondered why astronauts return from the space station weak and struggling to walk? Kate Poole dives into the physiological challenges faced by astronauts during and after their missions. She explores the effects of microgravity on the human body, including muscle atrophy and bone density loss. Poole highlights the cutting-edge research and innovative solutions being developed to mitigate these issues, so that astronauts can withstand long-duration spaceflights. She highlights the need for long term planning to achieve these goals and draws parallels between space medicine and fundamental research into how our bodies function.
