In addition to the policy issues Bob mentioned, the biggest change is that the
launch vehicles have gotten significantly larger. They've grown and
standardized to the point where the price/kg to orbit is not so much driven
by mass but by engineering and production costs. The result is that Intelsat
can host payloads of our expected mass without having to off load a
compensating amount of fuel. Since they can launch fully fueled the impact
to the spacecraft lifetime and their ability to generate revenue is
minimized.
During my talk at the Symposium I used the WGS and AEHF satellite programs as
examples of GTO launches with excess capacity. They have 1500 lbs and 1000
lbs respectively and there will be multiple flights of each. So there are
also other avenues being explored as well.
