1. Low Earth orbits (between 200 and 2000 km above Earth’s surface) are the most heavily polluted with space debris (computer simulation). 2. Numerous satellites and high volumes of space debris are present in geosynchronous orbits, particularly orbits at approx. 35,785 km above Earth’s surface (computer simulation). 3. View from the North Pole, depicting the density of objects in low and geosynchronous orbits (computer simulation)

In the movie “Gravity,” fragments of an old, disused satellite crash into a space station. The collision results in the formation of a high volume of debris, which in turn damages more satellites, causing the breakdown of GPS and the Internet, putting our planet on the brink of chaos. Although this is merely a science fiction blockbuster, the situation it depicts could easily occur in Earth’s orbit. How can we prevent it from happening?
