“...it is obligated to deliver until its de-orbit, planned for 2016....”
Does that mean de-orbiting the ISS? If that’s done, it would be a waste. That’s nine years from now. Certainly it can be maintained longer than that. Mir was 15 years old when it was de-orbited. And they had all sorts of problems with it starting a few years before its end. ISS, OTOH, would be 18 years old in 2016. That just has to be a misprint.
