Space Junk - "If we don't do anything, space will become soon inaccessible"
Fifty-five years ago, the space age dawned with the launch of Sputnik 1, the world’s first satellite. It fell from orbit after 3 months and burned up upon re-entering Earth’s atmosphere. But, for most space craft, this is not the case. The proliferation of debris orbiting the Earth, primarily jettisoned rocket and satellite components, is a pressing problem for spacecraft and satellites. There are significant costs in avoiding collisions with space junk.
