Space debris is a major problem for space exploration. There are millions of pieces up there in orbit from flecks of paint to defunct satellites. It is a known challenge to space exploration creating a shell of uncontrolled debris which could cause damage to orbiting craft or astronauts. A team at Astroscale have a spacecraft in orbit whose singular purpose has been to rendezvous with a defunct Japanese upper-stage rocket module. On arrival it is to survey the debris to test approach and survey techniques to ultimately inform how we can remove them from orbit.

Private and military organizations are tracking some of the 170 million pieces of space junk orbiting the planet, but they’re limited to how small an object they can detect. Only chunks larger than a softball can be tracked with radar or optical systems, and that only accounts for less than 1% of the junk out there.
But a new technique is being developed to resolve space junk to pieces smaller than one millimeter in diameter.
