Satellites that fall from the sky Where do dead satellites go? Some of them drift away in space but most fall down to earth. In the next few days, a schoolbus-sized satellite will fall back to earth. NASA officials don’t know exactly where it will fall until about two hours before it enters the Earth’s atmosphere. Usually, satellites and payload modules disintegrate into smaller pieces as they enter the atmosphere, and the danger to people is not as high as one might imagine. NASA spokespersons added that there is a 1-in-3,200 chance that a person somewhere on Earth could be hit by falling satellite debris. Here’s a look at space debris found on earth.
