Next Generation Technology: "Space Tug" Built for Hardware That's Not Disposable

The CX-OLEV or "Space Tug" built by Orbital Recovery has received its first contract to service an in-orbit telecommunications satellite. This marks a milestone in satellite technology: it's finally cheaper to re-fuel the old one than throw it away and build a new one.
With the exception of the mildly successful Shuttle Transport System (Shuttle) operated by NASA, and a couple multi-use components of the Soyuz program, most Space hardware is disposable. Not intended for re-fueling or re-using in any way.
More than one scientist has publicly lamented this "disposable" type of Space program, arguing non-renewable means non-sustainable.
With the "Space Tug", however, a company can extend the life of a satellite by up to eight years, through autonomous navigation and flight control. It remotely attaches to the craft and takes over all control flight functions, then is turned over to the operator of the satellite for regular control.
Of course it's a European Space Agency program. They seem to be mastering the art of recycling in all facets of modern society.
