Did you know that companies and governments send more than one hundred satellites into space every year? And that most of those satellites continue to orbit Earth-even after they have stopped working? More than 500, 000 old satellites, pieces of metal, and other bits of junk currently pollute Earth’s orbit. And that number is growing. Astronomers, engineers, and politicians all agree that the future of space exploration is in danger if this debris isn’t taken care of. But the problem of garbage in space is difficult and expensive to solve. In this book, learn more about this problem and its potential solutions.
