I still don't understand why you need 3 satelites to cover all the 
communication with the Shuttle.
Aren't there enough tracking stations on the ground? 
There is (at least) a couple in the US, some in Europe and in Australia.
That should be enough , I think. But it isn't. Why?
 
An other question:
What are the costs for 1 Kg payload in the space shuttle, ariane and
(if it's known) with the Russian satelites.
