What would it be like to live in space

Ever wonder how astronauts eat, sleep, and stay sane while floating in a tin can? These TED Talks pull back the curtain on daily life beyond Earth. No sci-fi, just real human stories—microgravity mishaps, space food fails, and surprisingly mundane moments that'll reframe your idea of home. Perfect for space nerds and the rest of us earthbound dreamers.
