Why don’t astronauts get hit by space debris? Many people think astronauts are constantly dodging space debris, thanks to exaggerated media visuals. But in reality, space is vast and mostly empty—debris isn’t as densely packed as it looks in those images. The International Space Station (ISS) has a strict safety protocol. If any debris is predicted to enter a 50×50×1.5 km zone around it, the station fires its engines to adjust its orbit—this only happens about once per year. #space #astronomy #s
