 abstract={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?},
