No, it was the fact that it was too heavy and could not carry enough fuel to attain sufficient altitude to reach the ISS. That's why it was always used for research missions and had never been to the ISS.
It was also not on the correct inclination, but even if it had been, the above would have still applied. So even if they knew there was a hole in the wing, there wasn't anything they could have done.
It's the same with these satellites that are falling. They are too heavy for the amount of fuel they may carry, to escape from Earths gravity.
All of them up there will eventually fall back down. There is no other place for them to go.
Why do you think it took so long?You probably think it was the Sun's gravitational force as the reason behind the MESSENGER's 6-1/2 year flight plan in the aforementioned article, don't you?
You either do, or you don't.
What's an ex-centrifugal force?There is no try in the ex-centrifugal force, padwan.![]()
