Russian space agency plans to use laser to shoot space junk
Russian space agency Roscosmos is planning to evaporate space debris and junk floating around the Earth using high beam lasers with a three-metre laser 'cannon'. NASA estimates that there are more than 500,000 pieces of space junk, orbiting the Earth at speeds of up to 28,160 kmph. Scientists claim the clearing out of space debris will help ease space exploration.
