Scientists in China planning to destroy space debris with an orbit-based laser station.
They published a paper explaining how a space-based laser station would impact its ability to remove the junk.
Experts estimate that since 1957, there are around 500,000 ‘space junk’ fragments of old satellites, rockets and other debris
They move at a speed of 17,500 miles per hour above us.
