This junk-collecting robot could soon be cleaning up space

The robot was developed by start-up Astroscale, with help from Airbus. It can grab old satellites and other space debris, then nudge them towards the Earth’s atmosphere where they burn up. Astroscale says a 'throwaway culture' has prevailed since the start of the space age. More than 9,000 tonnes of space junk is currently orbiting Earth, says NASA.
