This doesn’t make much sense, though: “…the hardware itself will have to be deorbited when it reaches end-of-life. ‘ESA has a Clean Space Initiative. Anything that we’re sending to space, we have to think about the whole lifecycle, cradle to grave,’ Caplin said.”
It’s loony tunes to think that we’d deorbit something that size from GEO. It will be repurposed in some way in space, or at least go to a graveyard orbit.
