ESA's active debris removal mission: e.Deorbit (with annotations)

ESA's Clean Space initiative is studying an active debris removal mission called e.Deorbit, which will target an ESA-owned derelict satellite in low orbit, capture it, then safely burn it up in a controlled atmospheric reentry. e.Deorbit will be the world's first active debris removal mission, and will provide an opportunity for European industries to showcase their technological capabilities to a global audience.

e.Deorbit's robotic arm

ESA’s proposed e.Deorbit mission, shown left, using a robotic arm to catch a derelict satellite – the baseline capture method for what would be the world’s first active space debris removal mission, in 2024.

The Agency’s member state ministers in December strongly supported a ‘maturation phase’ for e.Deorbit, to foster the various advanced technologies required to make the mission feasible, from autonomous guidance to advanced images processing, along with a suitable capture mechanism.

The mission would first rendezvous with a large, drifting ESA satellite, then capture and secure it safely ahead of steering the combination down for a controlled burn-up in the atmosphere.

As well as the baselined robot arm, additional capture technologies are being investigated, including a net and harpoon.

In any case, grappling the derelict satellite would have to be done in a very rapid and precise manner to prevent e.Deorbit and its target rebounding apart.

The mission, being developed through ESA’s Clean Space initiative – tasked with safeguarding terrestrial and orbital environments – will be proposed for final agreement at ESA’s next Council at Ministerial Level, in 2019. It will place European industry at the forefront of the world’s active debris removal efforts and multipurpose space tugs.

I wonder what happens when the dead satellite tumbles. Can they still catch it?

presumably that's where net/harpoon tech might help... but the cleaner would have to survive being "reeled in" by the tumbling prey.
