Fifty years after launching our dreams into space, we’re left with a troubling legacy: tens of millions of pieces of orbiting debris in an ever-growing ring of debris which threatens the safety of our planetary orbits. Space Junk takes students on a journey which examines this very real problem and explores the challenges we face in protecting our orbits for the future. What exactly is out there? What is the risk to the extensive defense and communications satellite networks we depend on? What can we do to protect our planet from impacts which could alter its orbit, and ultimately, life on Earth?
