Human activities continue to pollute and contaminate Earth as well as its surrounding space. According to recent survey, as many as 500,000 small and large pieces of debris are orbiting our planet. While it is not easy to clean space, a team of researchers from Japan's Riken Research Institute has suggested an ambitious plan to eliminate the space junk.
According to the Japanese researchers’ plan, a powerful fiber optic laser mounted on the International Space Station (ISS) can be used to blast thousands of tones of debris.
