Japan comes face to face with its own space junk

A satellite operated by Japanese company Astroscale has chased down a 15 year-old piece of space junk and taken an up-close image of it.

The object is a discarded rocket segment that's about 11m by 4m (36ft by 15ft), with a mass of three tonnes.

It's the first time anyone has managed to rendezvous with so big a piece of space debris.
