Swiss Scientists Devising Space Junk Clean-Up Satellite
Description:The threat posed by space junk to orbiting satellites and spacecraft was highlighted at the weekend when a discarded piece of debris from a Russian rocket passed close to the International Space Station (ISS). According to Swiss-based scientists however, the threats could be removed with a robotic spacecraft they are developing to literally grab debris out of orbit. The team says CleanSpace One will be ready to launch in 2016.(3:31)
