Can somebody advise just how much of the total weight of a satellite is fuel? It seems logical that--absent fuel being probibitively heavy--the design engineers would have equipped their satellites with enough fuel to last through the expected useful lives of their satellites.

When we talk about 7 years, or even 5, we're talking two more generations of wafer fabrication development, battery development and cdma development. In 7 years, will we be buying G5 phones with 3 ounce batteries that last 100 hours between recharge? And, what data rates will we be looking for? In 7 years, I expect that the 9600bps (or is it 7200?--I think that got straightened out) will be deemed inadequate, and the old satellites would be replaced even if they are still functional.

So, the satellites may have been designed with technological obsolescence in mind, rather than physical deterioration.
