space junk

The United States and other countries in the European Union are joining together to develop a "code of conduct" that would establish rules for orbiting spacecraft and for mitigating the growing problem of debris, or "space junk".

“Space junk” and debris in Earth orbit is a big and growing danger to space vehicles, satellites and even the International Space Station.  That's why NASA scientists are looking at a new option for reducing the dangers of orbiting clutter.
