RemoveDebris: UK satellite tracks 'space junk'
31 October 2018
The British-led mission to test techniques to clear up space junk has initiated its second experiment.
The RemoveDebris satellite ejected a small object on Sunday and then tracked it using a camera and laser system.
This vision-based navigation (VBN) technology essentially tells a pursuing spacecraft how its target is behaving - how it's moving and even tumbling.
RemoveDebris has already tested a net system. In that experiment, a small object was again ejected before having a mesh thrown around it.
